[[caption-width-right:350:[[{{Invocation}} Jack in! [=MegaMan=], Execute!]]]]

''Mega Man Battle Network'' is a spinoff/reimagining of the ''Franchise/MegaMan'' series. Its basic premise is "WhatIf the ''Mega Man'' universe had a major technological breakthrough in computer networking instead of robotics?" (like in our world). ''MMBN'' is set TwentyMinutesIntoTheFuture where everything is completely run by the Internet and life is more-or-less peaceful. Everything -- cars, refrigerators, schools, the weather -- ''[[EverythingIsOnline literally]]'' EverythingIsOnline.

The programming required to run everything has gotten so complicated that humans cannot comprehend it by themselves. So they've created helper Artificial Intelligences, called Network Navigators ("[=NetNavis=]" or "Navis" for short).

The stars of the series are 10-year-old (at the start of the series) Lan Hikari and his Net Navi partner, [=MegaMan=].EXE.

Since power in this universe is through the Internet, public enemies are those who would conquer or destroy it. Viruses are monsters that must be destroyed, and hackers are able to control all of the things mentioned above that the Internet is connected to. (Even the Mafia is Internet-based.) Lan and [=MegaMan=], being the main characters, have to face these forces off.

The "Real World" and the Internet are separated from each other. Lan can help [=MegaMan=] out by giving advice and "battlechips" that grant special powers, but he is more or less isolated from the action. (Unless the part of the Internet that is being affected controls the environment he is currently in, like a runaway train, a cruise ship, the oven of his house, etc.)

The series is best known for its unique battle system. It's complicated in theory, yet simple in practice. Combat is conducted on a three-by-six block grid, with [=MegaMan=] on the left and his enemies on the right. When your meter fills up, you can select a certain number of battle chips to blast your enemies in real time while dodging their attacks. They can damage, heal, claim more territory for you, damage or remove enemy territory, summon assistants, and a host of other effects. Those are the basics, at least. It would take far too long to explain all the little clever details and tactical considerations (and [[GameBreaker insane unstoppable ultra-combos]]), so those interested should watch some videos to have a better idea of what it's like.

The series lasted for six games before concluding. It spawned a sequel series focusing on radio waves and set 200 years in the future, ''VideoGame/MegaManStarForce''.

There are several attempts to make a [[FanSequel fan-game continuation]]. The most progressive one in the developing, that mimics the original games in 99% is ''[[http://mmbnchronox.com/ Mega Man Battle Network Chrono X]]''; being programmed in GML (GameMaker Language). This game is freeware and only for PC with Windows XP or greater OS. Chrono X is also being ported to Android devices and can be played with Android 2.2 & greater.

For the anime/manga adaptation, see ''Anime/MegaManNTWarrior''.
----
!!Trope routine, set! Execute!

* AdultsAreUseless: For some ''incredibly odd reason'', nobody else seems to notice that the world's about to end. Yeah, some of the enemy bases are in pretty hidden locations, but in ''Mega Man Battle Network 2'', Sean is hiding out inside a large Condoninium building that's ''getting merged'' with the internet - Now ''how'' in the ''hell'' does somebody ''not'' notice that? This is lampshaded by Chaud when he says that the official netbattlers are all in La-la land.
* AllAsiansAreAlike: {{Invoked|Trope}} in the second game, when an NPC remarks that all Electopians and Yumlanders [[FantasyCounterpartCulture (i.e. Japanese and Indians)]] look alike.
* AllTheWorldsAreAStage: Done in the first game Final Exam style, where each part of the final area is a condensed version of earlier areas, complete with more complex takes on stage gimmicks (i.e. putting out fires in [=FireMan=]'s area, using numeric passcodes to unlock doors in [=NumberMan=]'s area, etc.).
* AlternateHistory: This series (and its sequel, ''VideoGame/MegaManStarForce'') are set in a spinoff reality of [[VideoGame/MegaMan the original games]] in which Dr. Light develops network technology instead and it ended up being researched more prominently than Dr. Wily's robotics. [[VideoGame/MegaManX Good thing, too.]]
* AlternateUniverse / {{Elseworld}}: The Robot Masters (and a number of other characters) from the [[VideoGame/MegaMan original series]] return, this time as artificial intelligences called Net Navis. Dr. Wily himself is a major force. Dr. Light's counterpart is here named [[BilingualBonus Tadashi Hikari]].
** It doesn't match up ''perfectly'' mind you:
** Several Robot Masters have two counterparts. Slash Man has a lookalike counterpart in [=BeastMan.EXE=] who would've probably been his only counterpart if Capcom hadn't insisted on continuing the series after ''VideoGame/MegaMan3'', which eventually gave us the [[InNameOnly radically dissimilar]] [=SlashMan.EXE=].
** Another example of this is Magic Man, who has both [[RobeAndWizardHat MagicMan.EXE]] and the much more comparable [[MagiciansAreWizards HatMan.EXE]].
** Don't forget about [[VideoGame/MegaManX Zero.EXE, Colonel, and Iris]]. Or [[VideoGame/MegaManLegends Glyde]].
** [[VideoGame/MegaMan8 Duo]] is perhaps the one flaw in the ForWantOfANail explanation of the universe. While the Nail may explain deviations on earth, Duo hails ''from space'', where the Nail doesn't reach.
** Some [=NetNavis=] are infamously dissimilar to their Robot Master counterparts. [=CutMan.EXE=], on the other hand, is identical save that big ol' [[BroughtToYouByTheLetterS C]] across his chest. [=QuickMan=], likewise is just a slightly fancier version of his [[VideoGame/MegaMan2 original]].
** Ring is a GenderFlip of Ring Man.
** Save for the MascotMook [[AddedAlliterativeAppeal Mett]], most viruses are unique. In the PlatformGame [[GaidenGame Network Transmission]], a bunch of the viruses are basically rehashes of the original Mechaniloids. Fitting, as the game itself largely an exercise in [[NostalgiaLevel Nostalgia]] with Battle Network flair.
* AnIcePerson: Dr.Froid/[=IceMan=].exe, Ivan/[=ColdMan=].exe, [=BlizzardMan=].exe, [=FreezeMan=].exe.
* AdamSmithHatesYourGuts: Notice how the price of HP Memories tends to increase the later in the game you encounter the stores that sell them. It's not just Adam Smith, it's the shopkeepers too!
** Not only that, but even within the same store, the price increases the more you buy!
* AllThereInTheManual: Navi Customizer Compression and Extra codes in ''Battle Network 3'' could be found hidden in manuals, the [[Anime/MegaManNTWarrior anime adaptation]], and even some of the {{Gaiden Game}}s. For instance, the passcode Lan uses to force [=MegaMan=] into the ridiculously powerful Aqua Custom Style in the anime? It's the bonus code for 200 extra HP in the game. (Don't bother looking for it in the dub, though...)
** Let's put it this way: since ''NT Warrior'' got shelved, this gets escalated to GuideDangIt for Americans and Europeans (Amerouppeans? Netopians?).
* AlwaysInClassOne: All of the human main characters except Chaud are in class 1.
* AlwaysCheckBehindTheChair: Multiple ports and chips are hidden in the over-world. All of the main games have bosses reappear on select tiles throughout the Net; as well, the password system hides its codes where you cannot see them due to the camera.
* TheAnimeOfTheGame: ''Anime/MegaManNTWarrior'' (''Rockman.EXE'')
* AntiFrustrationFeature: In [=MMBN6=], the area that triggers a boss fight is marked by a tile with a skull on it, so that you know where to save beforehand.
* ApocalypseHow: Duo plans to pull a Class X on Earth, because its primary inhabitants have been very, very naughty indeed for the past few centuries. How's he going to do this? Crash his [[ColonyDrop car]] into it.
* ArbitraryHeadcountLimit: Only 5 characters can take part in the Liberation Missions of ''Battle Network 5''. When at least 6 people are present, one of them (you can't choose who) will get left behind to [[HandWave stay on guard and watch for surprise ambushes]], which of course never happens. It's specially strange to see Colonel leaving Shadow Man on guard and then talking about the need for ''speed'' in the mission.
* AvengingTheVillain: Dr. Regal, [[spoiler:the son of Dr. Wily]].
* BabiesEverAfter: [[spoiler:The DistantFinale epilogue of game six shows Lan and Mayl get married and have a son named Patch.]]
** And an unlockable in in ''Mega Man Star Force 2'' shows that [[spoiler:Patch's Navi is named [=MegaMan=] Jr, who was made from code taken from [=MegaMan=] and Roll's programs.]]
* {{Backtracking}}: A lot of the time, you're required to go back to previous areas. It's completely necessary to rematch bosses too.
* {{Badass}}: Every fighting character, and many of the operators.
* BagOfSpilling: At the start of each game, Lan and [=MegaMan=] start off with a horrible folder, 100 HP, no sub memory, no Navi Customizer, nor any of the previous Soul/Cross transformations (safe for a few - and even then they have to regain them again).
** The sixth game [[LampshadeHanging Lampshades]] the BagOfSpilling aspect in one of the poems of the Poem NCP. [=MegaMan=] asks Lan where all his old chips and such go, Lan answers that he really doesn't know!
** At least [=MegaMan=] gets to use his charged shot from the beginning in ''Battle Network 3'' and beyond, [[{{Nerf}} though the charged shot can't be as powerful as it could be in the first game.]]
* BattleTops: [=TopMan=].EXE can spin or toss tops, although [=MegaMan=] is only able to copy the spinning.
* BeardOfEvil: Regal grows one in-between ''4'' and ''5'' to show that he's serious this time. Mr. Match sort of has a Goatee Of Evil going on.
* BewareTheNiceOnes: Mamoru all the way. Despite being a sick little kid in a wheelchair, it is revealed in the third game that [[spoiler:his father was a [=SciLab=] scientist who created the Undernet, and Mamoru is its current owner.]] Also, look closely at the Navi icon on the side of Mamoru's chair in his [[http://images3.wikia.nocookie.net/__cb20080613014610/megaman/images/b/bf/Mamoru.jpg artwork.]] Guess which Navi's icon that is--[[spoiler:Serenade!]] It isn't entirely confirmed, but it is widely speculated and is very likely that Mamoru [[spoiler:not only owns the Undernet, but is Serenade's operator and thus the ruler of the Secret Area and the operator of one of the most powerful Navis in the series]]. BewareTheNiceOnes indeed!
** Also, ''6''[='s=] Prosecutor Ito. It doesn't help that he resembles [[AffablyEvil Mega Man]] [[EyesAlwaysShut Juno]] from ''[[VideoGame/MegaManLegends Legends]]'' with a bowl cut and dye job.
* BigBad: Wily ''yet again'' for three [[spoiler:(actually four)]] games. Dr. Regal fills in for him in the other games.
* BigDamnHeroes: Lan and [=MegaMan=] in every other scenario in the games.
** And in at least one scenario per game, usually near the game's climax, they're the ones who need the backup.
* BigFancyHouse: Yai has one.
* BlackScreenOfDeath
* BlindIdiotTranslation / GoodBadTranslation: Found in many, many cases, spanning the entire 6 games (and the {{Gaiden Game}}s).
** ''Red Sun/Blue Moon'' are the most blatant offenders of this.
** Some Battle Chips are on the receiving end of this in the more arcane cases. The "Howitzer" Battle Chip is later known throughout the series as the "Cannonball" chip, which suggests somebody on the translation team realized ''Hougan'' is the Japanese word for "cannonball" and not a bizarre attempt at "Ho-Gun".
* BodyguardBetrayal: Happens in the sixth game, when [[spoiler: Chaud reveals his true identity and arrests Mayor Cain]] right as he orders him to arrest Lan.
* BondCreatures: Not exactly {{Mons}}, but the [=NetNavis=] themselves each have an operator. Rarely, you might meet a [=NetNavi=] without one, such as [[BonusBoss Bass.EXE]].
* BonusBoss: Bass's final form in every game, [=ProtoMan=] in ''3'' and ''6''. ''6'' also has [[spoiler:[[VideoGame/{{Boktai}} The Count]], who was cut out of the English version, though arguably he was more of a secret boss]]. [=PharoahMan=], and [=ShadowMan=] in ''1'', [=PharoahMan=] (again), [=NapalmMan=], and [=PlanetMan=] in 2, [=DarkMan=], [=YamatoMan=], and Serenade in ''3'', and the souped-up recycled bosses in the bonus dungeons of the others. Later games also have Lan and [=MegaMan=] fighting souped-up versions of the FinalBoss as well.
* BonusDungeon: Starting with the second game, we have the [=WWW=] Area, the [[ExactlyWhatItSaysOnTheTin Secret Area]], Murkland (a sort of cyber-Hell), Nebula Area, and the Graveyard.
* BoisterousBruiser: [=GutsMan=].
* BoringButPractical : Obstacle chips, and Terrain changing chips, especialy in the third game where lots of [[GameBreaker Game Breaking strategy]] is made and broked by the same kind of chips.
* BossRush: Found at the end of most games; in addition, the time trials in ''[=MMBN3=]'', but they come with asinine requirements.
* BrainUploading: [[spoiler:[=MegaMan=] himself.]]
* BreakingOutTheBoss: The SealedEvilInACan immediately swallows up Wily in the third game after the program limiting its power is destroyed.
* BrokenAesop: In the fourth game, at the beginning of the first tournament, Lan and [=MegaMan=] defend some viruses from a navi who "weren't doing anything wrong," but later in Match's scenario, when Match says that there is a place for everything, even viruses, which he shouldn't simply delete on sight...which he was using to power a hot dog oven...(?) to which Lan disagrees...
* BrokenBridge: The electronic equivalent, a bad net connection, is used to prevent Mega Man from going too far into the net.
* BroughtToYouByTheLetterS: Most Mega and Giga class chips have the first letter of their name as their chip code. This also applies to Navis like [=ProtoMan B=] and [=SpoutMan A=], in that their [[DubNameChange Japanese-name counterparts]] match the chip-code ([=ProtoMan=] = Blues, [=SpoutMan=] = [=AquaMan=]) -- recurring chips like Meteors R (''Ryuuseigun'', Meteor Swarm) and Guardian O (''Ojizousama'', a Buddhist protector figure) are also victims.
** For extra fun, alphabetize your chips in ''[=BN4=]'' and notice where the Meteors chip gets sorted to.
* TheCameo: ''HideoKojima'' himself in ''Battle Network 4''. In-universe, Rogue of ''VideoGame/MegaManStarForce'' appears as a battle chip and enemy summon in ''Operate Shooting Star''. Also the cameos of VideoGame/{{Boktai}} characters, especially Django.
* CallBack: The first thing that Lan solves is an oven that spits fire in his house. In a later game, someone in a line to report complaints says, "My oven's spitting fire!"
** The response to which is the accusation of that being an old story. Also of note, [=FireMan=]'s second game allows you to Jack In to the oven again, though nothing of particular note happens there except for the tutorial.
* CallingYourAttacks: [=FlashMan.EXE=] falls victim to this a couple of times in ''Battle Network 3''. "Hypno Flash!"/"[[MundaneMadeAwesome SHINING... BROWSER... CRASHER...!]]"
** In general, whenever a Navi is using an ability, particularly in cutscenes. Notably in ''Battle Network 5'' where, during Liberation Missions, [=MegaMan=] and their allies will yell out their special abilities' name before executing it. Same goes with the bosses in said missions.
* CardCarryingVillain: Dr. Regal.
* CastFromHitPoints: Dark Chips in ''4'' and ''5''. One of the most extreme examples of this trope: using a Dark Chip only costs 1 HP, but that hit point is gone ''permanently.''
* ChaosArchitecture: Used, averted and justified.
** Explained: The Internet is constantly undergoing updates so massive, people don't even bother to care when the immediate cyber-neighborhood looks nothing like it did in the previous games. You might find a few similar areas here and there (a particular section of the Undernet in ''4'' is reminiscent of an area from ''2'').
** Unexplained: [=ACDC=] Town has a remarkably different geography in the second half of the series; the only remaining trait is that Lan and Mayl are next door neighbors.
* ChekhovsGun: In ''[=BN3=]'', whenever you make a detour to [=SciLabs=] Net Area, you will see a floating cube thing guarded by four doors. If you haven't played the game yet, that ''thing'' is [[spoiler:Proto/Alpha, the game's ''FinalBoss''.]]
** Lan's house has a dog house behind it. In the first four games, nothing is ever said about it and you would just think it is for security like the other one, but then the fifth game finally makes it a plot point.
** ChekhovsGunman: Iris in the sixth game.
** Also see ObfuscatingInsanity below.
*** Mr. Mach as well for a minor example.
*** A certain gray-haired boy in the second game is [[spoiler:Sean Obihiro, the ''BigBad'']] and an orange/redheaded scientist in the third is [[spoiler: [[Characters/MegaMan Dr. Cossa(c)k]], creator of Bass.]]
**** [[spoiler:Shun first appears on a plane, perhaps to oversee one of his lieutenant's operations -- though he's kind of hiding in the back of the plane; Dr. Cossack, on the other hand, first appears as an optional talking NPC who lectures you for exploring being out of bed that late at night; another notable Gunman is a little boy you meet named Mamoru whose chief characteristic is that he's suffering from the same heart condition that took Hub/[=MegaMan=]'s human life; turns out he's the administrator of the Undernet.]]
** Many fetch quests usually have you running across the item you need in the background somewhere, but you don't notice it until you're told you need it, then you need to go looking for it.
** ChekhovsClassroom: Every once in a while in the first few games. In ''3'', we find the class discussing program compression at the beginning of the [[{{Gonk}} BubbleMan]] chapter.
* ChestInsignia: Just about every unique Navi has a unique insignia, and if it's not on their chest, they'll definitely have it close by. Their operators also tend to display that same insignia on their [[MartialArtsHeadband headband]], earrings, hairclips, you name it.
** Subverted by Bass, who had one at one point, but instead has a massive scar that he keeps as a reminder of his betrayal by humanity.
* ChestMonster: Viruses inside trapped mystery data, of which said data is usually trapped more frequently by anonymous jerks in the less regulated parts of the internet.
* ChuckCunninghamSyndrome: Sean. He turns out to be [[spoiler:the BigBad]] in the second game, then shows up in the third game for one scene in the hospital. After that... he just walks off. Maybe he fell into a PlotHole after leaving the hospital.
** Other WWW members and antagonists have left and never returned. Yeah, some were arrested (The WWW members in ''3'', Dave) or possibly killed (Arashi) but some seem to have just vanished without a trace (Ms. Madd, Yahoot, Count Zap).
*** In ''Cybeast Gregar'', if you undergo an optional sidequest, you will wind up talking to Count Zap's wife, where you and her mention that he was imprisoned.
*** In the main games, maybe. Most/all of the main characters and villains from ''1'', ''2'', and ''3'', show up in ''[[GaidenGame Battle Chip Challenge]]'', notably sans Mamoru (especially bizarre in that you can fight his ''mother'', the proprietor of the Ura Inn). Shun's the final battle of one of the last tournaments, and the WWW members have at least one scene to themselves. ([[ShoutOut Funnily enough]], they're discussing [[Anime/MegaManNTWarrior curry]]). And Sean was part of the ensemble finale in ''3''. Of course, then he and Mamoru both disappear.
* ColdBloodedTorture: In the first game, [=ColorMan=] ([[PsychopathicManchild a misleadingly-friendly looking Navi]]) is torturing Roll ''for fun'' after defeating her. Fortunately, [[BigDamnHeroes MegaMan intervenes]].
* ColdSniper: [=SearchMan=]
* ComicBookTime: The main six games take place over the course of two years (5th and 6th grades), but event narrations will remark far too quickly that "several weeks/months" have passed over one or two games' course. See also "NotAllowedToGrowUp" below.
* CommandRoster: In ''BN5'':
** TheCaptain: [=ProtoMan=]/Colonel\\
NumberTwo: [=MegaMan=] (TheHero of the story)\\
The Marine: [=NapalmMan=]/[=TomahawkMan=]\\
MrFixit: [=SearchMan=]/[=NumberMan=]\\
Security Officer: two for each team: [=GyroMan=]/[=ShadowMan=] (for scouting areas) and [=MagnetMan=]/[=KnightMan=] (for defense)\\
TheMedic: Meddy/[=ToadMan=]
* CompositeCharacter: This universe's version of [=ProtoMan=] seems to be a mix of the [[VideoGame/MegaMan original]] and [[VideoGame/MegaManX Zero]], being based on the former but with the hair, LaserBlade and social standing of the latter. Also, the Battle Chip "Z-Saver" (mistranslation of Z-Saber, Zero's trademark weapon) is sometimes associated with [=ProtoMan=].
* ContinuityNod: Lan and [=MegaMan=] will recognize a good number of their teammates in ''Battle Network 5'', with the notable exceptions of [=SearchMan=] and [=NapalmMan=]. In [=SearchMan=]'s case, it could be {{justified|Trope}} that he's a random possibility among many in ''Red Sun''. In [=NapalmMan=]'s case, it could be that the bonus areas of the games aren't canon.
** A woman in ''Battle Network 2'' complains that her oven has spat fire. The clerk she's talking to says that's an old story (it happened to Lan in ''Battle Network 1'').
* TheCorruption: [[MadeOfEvil Dark Chips]] have immense power and force themselves to the top of the deck when you're hurting, but will permanently remove one hit point per use and slowly twist users into an evil, mindless LivingShadow. Cybeasts in ''[=BN6=]'' provide great strength, but will take over and rampage if given half a chance. Just say no, kids. Or, in the case of the Cybeasts, just make sure not to use it for more than three turns in a row.
** Dark Chips can be used if you have the [[DummiedOut Dark License]] program or can master the [[SuperpoweredEvilSide Chaos Unison]] form.
* CreativeClosingCredits
* CrosshairAware: All over the place since the beginning, even more so when ''4'' rolled out Cursor and other secondary elements for chips and viruses.
** Don't forget the scenario in ''4'' (''Red Sun'' version) where [=SearchMan=] is taking potshots at you with his [=ScopeGun=]; you can literally see the crosshairs lock onto Mega, along with the direction you need to dodge in order to not get shot.
* {{Crossover}}: Subverted with ''Operate Shooting Star''; the game was promoted on the alleged crossover between Lan/[=MegaMan.EXE=], and Geo/Omega-Xis. However, this so-called "crossover" only takes the form of an additional scenario, a Navi Chip, and a key item that lets the player "switch" between ''EXE'' and ''Star Force''-era Mega Man, and even use the ''Star Force'' version's shield ability. Otherwise, it's ''just'' a remake of the original GBA game.
* CutscenePowerToTheMax and CutsceneIncompetence: [=MegaMan=] slowly shifts from the first to second as the series goes on to the point in which he's almost always at the mercy of something by the sixth game. To get an idea of how bad this is for him, see the RescueArc entry below.
** All of the other main characters appear to exclusively follow the first one though. Especially [[TheRival ProtoMan]].
* {{Cyberspace}}: Specifically TheMetaverse, although Net Navis are independent, sentient individuals instead of just user avatars.
* CyberPunkIsTechno
* DamnYouMuscleMemory: The option to skip cutscenes was changed from the Start button to the Select button during the latter three games. Somewhat justified; having the "Skip Cutscene" button be the same as the "Bring Up Menu" button had some annoying consequences.
** In every main series game from ''1''-''6'', the B button was used to run in the overworld. However, ''Operate Shooting Star'' (in the vein of ''Star Force'') changed it so that characters automatically run, and the B button makes them walk.
* DangerousWorkplace: There are a few examples that apply directly to this trope. In general though, chances are that if you can visit something as Lan in the Real World, you're going to have to defend the place as [=MegaMan=] in the Cyber World.
* DarkestHour: At the end of every main game, people are practically waiting for the apocalypse - notable in three as MILITARY LAW and TANKS are being applied.
* DeadlyDoctor: Meddy
* DemotedToExtra: Bass in the fourth game and beyond turned into a plot-insignificant post-game BonusBoss again. He even seems to lose his memories all the time and doesn't recognize Mega Man. Also, some chips available in the later games are from viruses that don't actually appear in them. In those cases, the picture of the virus in the chip is monochrome.
* DifficultySpike: In each installment, any of three things will represent a difficulty spike: Entering the [=UnderNet=] (where [[GoddamnedBats powerful and tricky viruses]] are suddenly abundant and random battles are now deadly), reaching the FinalBoss (who usually packs upwards of twice the HP of previous bosses, more damage with faster attacks, and regenerating shields or temporary damage immunity), or facing a [[RecurringBoss version 3 boss]] for the first time. Outside of those things, the main games are pretty easy if you're actually exploring, collecting powerups, updating your folder, and so forth - suddenly being at high risk of dying from any of those things even when well prepared is a pretty significant difficulty spike. And just when you get to the point where all those things become easy (And you will), there's always the ultimate [[BonusBoss Bonus Bosses]] to stress you to your limits.
* DiskOneNuke: In all games featuring the Numberman trader, with an on-line guide to tell you the trade codes you can get rare and powerful chips and Navi cust programs early in the game.
** In the sixth game, in the very first area, you can obtain from the random encounters 5 Reflector1 As and 5 Machine Gun1 As. These, along with three Train Arrow As you can get in another early area (and [=SpoutMan=] if you're playing ''Falzar''), can and will see you through the entire game.
** In general, if you're willing to spend a bit of time grinding, you can assemble dual or monocoded folders very early in the game, which significantly reduces the challenge.
** In ''Network Transmission'', the Mini Bomb chip is for once actually useful. To be certain, against bosses it's not so hot but it's capable of pretty much destroying or at least crippling every basic enemy in the game that doesn't have an aura since it hits more than once. And the best part? You can get it at the beginning of the game since Higsby sells it for a measly 150 zenny. And since its a beginning chip, you can hold up to 30 and easily set it as your regular chip.
** As another general rule, Mega Chips (the ones you get by (re)beating bosses, and a few others with similar power level) run the gamut, but many are capable of winning random encounters in one move for much of the game. Many hit the entire screen or a good portion of it and do lots of damage and/or disable enemies. The 3 chips for the first boss of ''[=BN6=]'', for instance, hit all three rows for 120+ damage and the first area with enemies with more health than the chip takes off is the wood area, where everyone takes double damage from fire. In ''[=BN3=]'' the first boss's chip does 50+ damage to the whole screen, double on ice or vs water, while guard state and mercy invincibility and inflicting paralysis. To make up for this, though, you can't rely on getting these chips every battle; you'll just have a 5-7 in 40 chance of ending every random encounter in one turn for each chip like that you posess.
** ''[=BN6=]'' to an extent is full of these. The Cross is acquired relatively early compared to other ''BN'' games upgrade and has arguably the best and most useful effect and can be used just by pressing up on Custom Screen. It's also possible to beat the V3 version of the first boss in ''[=BN6=]'' especially easier in the ''Falzar'' version after getting the first Cross in a matter of seconds. You can get the full power version if you grind the correct chip and said correct chip is in the beginning area. At full power, the chip does 250 damage to the whole column.
** A bit of grinding and searching in the earliest portion of the games will net you the ingredients of a Program Advance, generally Zeta/[=Giga-Cannon1=]. It's also possible to put together a Flame Hook and Fire Burner P.A. in ''6'' before [=BlastMan=].
* DidYouJustPunchOutCthulhu: The Life Virus, [[GaidenGame Zero, Life Virus R]], Gospel, Alpha/Omega, Duo, [[SuperpoweredEvilSide Yourself]], Nebula Gray, Lord of Chaos, Cybeasts Falzer and Gregar, [[BonusBoss Bass]], and [[BonusBoss Serenade]] all qualify.
** And even more: in ''[=BN3=]'', one of the {{Bonus Boss}}es is actually Bass merging with Gospel's remaining datas, while in ''[=BN6=]'', as his last form, he merged with the opposite version's Cybeast (Gregar in Falzar version, Falzar in Gregar version).
* DoNotGoGentle / PatrickStewartSpeech / RousingSpeech / ShutUpHannibal: The long speech at the end of the fifth game. [[http://www.gamefaqs.com/ds/928331-mega-man-battle-network-5-double-team/faqs/38674 you can read the speech here]] and [[http://forums.somethingawful.com/showthread.php?threadid=3326989&userid=0&perpage=40&pagenumber=114#post387616218 view pictures here]] (scene 153, for the dialogue).
* DressingAsTheEnemy: In ''Battle Network 3''. Well, not ''exactly'' "dressing". [=MegaMan=] actually can run a program that sort of makes him "feel" evil, so that the navis in the Undernet think he's one of them, without [=MegaMan=] actually changing shape. (You'd think they'd recognize the Navi model of the guy who busted up Gospel's Undernet-based dealings a year ago, but eh.)
** He's actually generating an evil ''aura'', and in later games, the [[DummiedOut program]] can allow free use of Dark chips. The malevolent presence wards off suspicion like nobodies' business. In ''[[GaidenGame Network Transmission]]'', however, he ends up needing to cop an attitude like [[{{Jerkass}} NeedleMan]] to [[TheGuardsMustBeCrazy convince]] the guard he's {{Badass}} enough to get into the Undernet.
* DubInducedPlothole: Why are [=ProtoMan=], [=EraseMan=], and [=SpoutMan=] in the b, k and a codes? Because they are '''B'''lues, '''K'''iller[=Man=] and '''A'''qua[=Man=].
** The sixth game used [=AquaMan=].EXE's ''Anime/MegaManNTWarrior'' name of [=SpoutMan=], despite him being [=AquaMan=] in ''4'' because [[Comicbook/{{Aquaman}} DC just decided to randomly enforce their rights to the name in America]].
** Doesn't matter anymore because ''Operate Shooting Star'' changed [=SkullMan=] to D code and [=ShadowMan=] to T code. This is to spread out the variety of Navi codes, because there are a lot of S-named Navis in the game.
* DudeWheresMyRespect: So Lan saves the entire internet (and the world sometimes) every game. You'd think he'd at least get recognized by the officials and be acknowledged as being more than just some kid right? Haha '''no'''.
** Of course, there are some aversions. ''[=BN3=]''[='s=] InevitableTournament introduces Lan as the kid who stopped WWW, and ''[=BN5=]'' has Lan getting recruited to stop Nebula. Also, Chaud, while a jerk, at least recognizes Lan.
** Unfortunately, there are even more cases where this is played annoyingly straight. Perfect example: ''[=BN4=]'', [=SearchMan=]'s scenario. Raika, despite being a high ranking military officer, has apparently never heard of Lan, Mr. Saved the Internet Three Times At This Point. He treats Lan as a joke, and when Lan heads over to Sharo to help Raika out in a mission, an official all but tells him to go home, saying the Undernet (incidentally, as of ''[=BN3=]'', [=MegaMan=] was the KING of the Undernet) is far too dangerous for him. Then [=SearchMan=] spends the rest of the scenario sniping [=MegaMan=].
** The afformentioned status as King of the Undernet makes one question the way the undernet dwellers respond to your presence, in every game from the point you recieve this stats in the third one onwards...particularly when a group of cultists kidnap you in the 6th one (twice).
*** Partially justified, as the denizens of the Undernet are unlikely to care about their king enough to respect them -- just treating the king good enough to not make him delete you is likely their priority. On top of that, it's not like Mega is leaking power like [[spoiler:Serenade]] was, so maybe they didn't even realize that Mega became their king. As for the two times in ''6'', they're [[spoiler:a group of Cybeast worshipers that want to free the Cybeast from Mega's control.]] It's only natural that they would go up against even the Underking to get what they want.
* DummiedOut: A few.
** Lines from [[http://www.youtube.com/watch?v=JYIDuv6l5GY Twin Leaders]], [[http://www.youtube.com/watch?v=D7ZDjeSP7fQ Double Team]], and [[http://www.youtube.com/watch?v=cNbIkuSB8Ow Operate Shooting Star]].
* EasterEgg: [[http://www.youtube.com/watch?v=ueMGFoEvuFg So]], apparently there ''is'' Christianity in the Network-verse.
* ElementalRockPaperScissors: Fire beats Wood beats Elec beats Aqua beats Fire from day one; ''6'' implements the [[TacticalRockPaperScissors tactical variant]] for the secondary elements (Sword beats Wind beats Cursor beats Breaking beats Sword).
** Also some sort of ReviveKillsZombie: Sword chips pierce the Shadow defense, while Cursor chips go through Invis and post-hit invincibility; Break chips, er, "break" through shielded enemies, and Wind chips remove barriers and auras.
* EldritchAbomination: Cache, from an obscure GaidenGame as well as the FinalBoss during the Beast+ season in the anime. In the main games themselves, all final bosses qualify; especially Gospel as it's made of multiple bugs (and by the same token, Gregar), and Nebula Grey, which is literally MadeOfEvil (of the humanity's mind, specifically).
* EleventhHourSuperpower: Full Synchro, until it is downgraded and usable throughout the game in ''[=MMBN4=]''.
** Full Synchro doesn't actually do anything mechanically in ''2'' and ''3'' - the first does have your stats go up considerably during the last stage due to a last-minute powerup. It's possible to take out the final boss using nothing but blasters!
** Hub.bat in the first one. It's actually possible to beat the final boss by ''just spamming the B-Button''.
** Subverted in ''5''; [[spoiler:during the cutscene after Mega Man successfully defeates Nebula Grey, it regenerates and then tries to take over Mega Man's body. All hopes seem lost... when suddenly Mega Man turns into his full Hub form and wards off Nebula Grey with little effort. The subversion comes when he turns back to his normal form - and Nebula Grey goes back to strike him ''yet again''. Fortunately there's Colonel (and others) to help him defeat NG with a final, supercharged Mega Buster.]]
* TheEnd: We got a "The End" title card in ''Battle Network 6''.
* EnemyCivilWar: Occurs halfway through the sixth game.
* EvenEvilHasStandards: Lord Wily was very disapproving of [[spoiler:the actions of his son, Dr. Regal]].
* EvilIsHammy: Dark Chips are described in ALL CAPS. Dr. Regal, too (though in the usual dramatic way); as a fun fact, he's the Dark Chips' creator.
* {{Expy}}: Several of the Net Navis are based on characters from the Robots timeline of the VideoGame/MegaMan series.
** Prosecutor Ito is basically Light from Manga/DeathNote in personality.
** There are also expies of characters from past Battle Network games. Case in point, Captain Blackbeard is basically the Battle Network 6 equivalent of Takeo Inukai of Battle Network 3, right down to job (or in the case of Blackbeard, former job) and their plans involving chaos caused by animals (in an Aquarium and in a Zoo, respectively).
* ExtremeGraphicalRepresentation: Oh dear ''god'', you could practically rename the trope "[=MegaMan=] Interface". The cyberworld is exactly like the human world, complete with water, fire, weather, and plants including full-grown trees. Just slap the prefix "cyber" in front of the usual term.
* FakeLongevity: Plenty of examples...
** The backtracking. Most of the RealWorld segments in the first game are running back and forth between a few areas. The Waterworks stage is likewise hated for this.
** The castle stage in the second game, which features zombies, vampires, and burglars harassing you. In the Zombies' case, they take you across the map...and the map seems artificially lengthened.
** The hospital in the third game, which requires a bunch of fire chips to get through obstacles in the stage.
** Almost all of the fourth game is made of this, due to Lan taking on problems from his competitors.
* FamilyUnfriendlyViolence: For a series aimed at the younger set (at least in the English version), ''EXE'' has some pretty horrific stuff going on. Mass poisoning, terrorist bombings, gangsters being murdered by their own employers with briefcase bombs, and it just goes on like this...
* FantasyCounterpartCulture: Pretty much ubiquitous. Electopia is Japan (they didn't even bother pretending it wasn't Japan in the Japanese version, incidentally), Netopia (Amerope) is an amalgam of America and western continental Europe, Creamland is a mishmash of northeastern European countries, Kingland is the United Kingdom, etc. Some of the counterparts' names get a little unimaginative, like Sharo, which is basically Russia with the syllables reversed, or Choina and Netfrica (Affric), [[CaptainObvious which you should be able to figure out for yourself]]. The only one they seem to have put any effort into is Yumland (Ajiina), which would be India (famous in-universe for its food and massive population).
* FightLikeACardPlayer
* FiveManBand: The Navi teams in the fifth game are technically made up of seven members, but you never actually control them all at once, and their roles are pretty easy to figure out since they're usually recruited for specific purposes.
** TheLeader: [=ProtoMan=]/Colonel\\
TheLancer: [=MegaMan=] (TheHero of the story)\\
TheBigGuy: two for each team: [=MagnetMan=]/[=KnightMan=] for defense, and [=NapalmMan=]/[=TomahawkMan=] for offense.\\
TheSmartGuy: [=SearchMan=]/[=NumberMan=]. They specialize in finding traps and eliminating them.\\
TheSneakyGuy: [=GyroMan=]/[=ShadowMan=]. Able to walk on Dark Panels, they specialize in recon.\\
TheChick: Meddy/[=ToadMan=]. Have supportive abilities.
** It could be argued that most of the games end with a Five-Man-Band of sorts being formed on the spot to [[StormingTheCastle storm the castle]] (often literally). [=MegaMan=] is always TheHero, [=ProtoMan=] is always TheLancer, and [=GutsMan=] is always TheBigGuy, but the others vary quite a bit:\\
[[TheSmartGuy NumberMan]], [[TheSixthRanger IceMan]], [[TheChick Glyde]], and [[TheHeart Roll]] in ''[=BN1=]'';\\
[[NonActionGuy Glyde]] (who does absolutely nothing) and [[TheChick Roll]] (who gets a BigDamnHeroes moment, to her credit) in ''[=BN2=]'';\\
[[TheSmartGuy KingMan]] and ''almost'' Glyde and Roll in ''[=BN3=]'', but it's decided that [[TheLoad they would just get in the way]], even though Yai and Glide made it just as far in the N1 Grand Prix as Dex and [=GutsMan=].
*** What's really funny is that Yai ''points this out'', but then goes along with their decision in the end, since Glide's strength is Yai's massive load of rare chips, rather than his own power.
** The main characters make a FiveManBand too:\\
TheHero: Lan\\
TheLancer: Eugene\\
TheSmartGuy: Yai\\
TheBigGuy: Dex\\
TheChick: Mayl
* FiveBadBand: The sixth game is the only ''Battle Network'' game where the villains other than the BigBad had any real focus past their initial scenarios, and actually interacted with each other. Most villains in the other games usually showed up alone, did their thing, and disappeared (presumably dead, locked up in prison, or fled after their defeat) for the rest of the game.
** For most of the sixth game, the Band is the following:\\
The BigBad: [[spoiler:Baryl/Colonel.EXE]]\\
TheDragon: [[spoiler:Mr. Mach/[=BlastMan=].EXE]]\\
The EvilGenius: Prosecutor Ito/[=JudgeMan=].EXE\\
TheBrute: Two of them - Blackbeard/[=DiveMan=].EXE and Vic/[=ElementMan=].EXE\\
The DarkChick: Yuika/[=CircusMan=].EXE
** Towards the end though, the group splits into two. The BigBad and TheDragon remain together, while Yuika moves up and takes a combination of both positions for her group. This leads to hilarious results regarding Yuika's group after [[BossRush MegaMan.EXE defeats them all for the second time]].
* ForcedTutorial: One in every game. [[OncePerEpisode Every. Game.]] It will consist of three (3) virus battles against groups of Mettool viruses. You will have one (1) crappy folder that has [[BagOfSpilling no business whatsoever]] being in the hands of a world-saving duo. The first three games will actually employ the ''same exact tutorial'' (virus killing, chip combos, chip adding) with the ''[[RunningGag same exact folder]]'' in the ''[[RuleOfThree same exact sequence]]'', though there are different teachers depending on the game. The second half of the series trades out Chip Adding for an Emotional State (Full Synchro) tutorial, which is more dynamic a system.
** The Gaiden Games Network Transmission and Battle Chip Challenge require tutorials as well, though these are far less aggravating, since they are actually conflated with the opening levels.
** HeKnowsAboutTimedHits: Actually done well in the main game tutorials. The human operators are themselves using little handheld terminals, so banter about the L and R Buttons fits right in.
* ForWantOfANail: [[WordOfGod Supposed to be a world where Light turned to computer networking technology instead of robotics]]. All well and good...so, how does that explain Duo?
* FreudianExcuse: Most of Gospel in ''2''. It helps to make them more sympathetic - and their face-profiles even portray them as completely normal looking people, whereas teh
** Possibly justified in that [[spoiler: Wily]] might have been trying to ''kill'' Lan, considering [[spoiler:" his defeat the first game could have lead him to try and eliminate him for his next plot.]] Most of the attacks seem too specified (i.e. gassing Yai's house and no other) to be general terrorist plots.
** [[spoiler: Sean's FreudianExcuse may ring especially true for some people...specifically the parts where he mentions that the internet was the only way he made friends.]]
* GameBreakingBug: See "UnwinnableByMistake."
* GatlingGood: The Vulcan chips and Super Vulcan. Due to this trope (they deal damage by hitting for 10 points multiple times), combined with a few chips to boost attack ([=ColorPt/DblPoint=] and ATK +10/+30), they get the boost to each individual hit and thus can deal a OneHitKill on bosses.
* GenericDoomsdayVillain: Dr. Regal in the fourth game. His character (slightly) improved by the time the fifth game came along.
* GeoEffects: Standing on grass made elementally-aligned units heal but doubled the damage from fire, ice and water interfered with movement but made you weak to electricity, and so on. Some games got "creative" with magnet panels, conveyor panels, gravity panels, and in ''3'', a panel that was a hole into the Internet netherworld.
* GenderFlip: The Robot Master Ring Man was adapted into a female Navi named Ring for ''Battle Chip Challenge''.
* GetBackHereBoss: [[VideoGame/MegaManStarForce Mega Man Geo-Omega]] is the first type, as he fires at you with the [[ArmCannon Megabuster]] and then runs, only to repeat it when you catch up to him a second time, of course he finally does fight you the third time you catch up to him. The chase sequence can be watched [[http://www.youtube.com/watch?v=izqUOZIdeDo here]] and [[http://www.youtube.com/watch?v=9PMP3OnW7kw here]].
** [[OurVampiresAreDifferent ShadeMan.EXE]] too, in ''4''.
* GettingCrapPastTheRadar: A BigLippedAlligatorMoment onboard the plane in ''Battle Network 2'', [[spoiler:in which Lan must retrieve booze from a badmouthed rapper (who, by the way, doesn't supply the ''only'' cursing in the game) by joining in on a song rife with ''barely'' [[DubText subtextual]] sexual imagery.]] What descriptors did the ESRB give this E-rated game? Comic Mischief, and... nothing else.
** Everything that Ms. Millions says. [[WhatDoYouMeanItsForKids It's pretty much outright stated that she gets sexual pleasure from Net Battles, even going so far as to call you a dirty boy after you defeat Snakeman V3.]]
** In ''[=BN1=]'': [[http://www.youtube.com/watch?v=OyaUzESCm5w Lan is peeping Mayl changing clothes.]]
** The aforementioned whiskey rap, from [=MMBN2=]. In that same game, Gauss shouts "Damn it to hell!" after his plans are foiled.
** The second game tends to be filled with swearing. There's also the infamous dialogue of Yai accusing (and teasing) Lan for seeing her naked.
** A bit of a literal example is in Battle Network 3 during the zoo incident where sprites of animal feces are shown. The word ''poop'' also shows up visually when the player examines the elephant before the animals go beserk, and the end credits depict another sprite of feces.
** In 6, a plumber's navi loses his tool program (which looks like a plunger). Lan and Mega Man offer to find the tool program for the navi. Guess where the navi lost his program? In Lan's toilet. That's right, Lan has to jack Mega Man into the toilet's computer network to retrieve the tool program. Also, the tool program is stuck to a Mettaur's head.
* TheGift: Lan's got it; [[WellDoneSonGuy Chaud]], who is declared to spend ten hours a day training, apparently missed out.
* GlobalCurrencyException: [=BugFrags=], which are pieces of junk data, can be traded in for some of the rarer Battle Chips and [=NaviCust=] programs. Those [=BugFrags=] tends to be either ridiculously easy or rip-your-hair-out hard to find depending on the game.
* GoodIsDumb: The Navis you can control in ''5'' and ''6''. When you face them as bosses, they have more then 1000 HP (more than you can ever have naturally) and various attacks. However, when ''you'' control ''them'' they have at max 800 HP, less than the max for [=MegaMan=] (1000), but even if you fight them again afterward, they go back to their massive HP.
** Arguably {{justified|Trope}} in that, specially in ''6'', it is ''Lan'' controlling them instead of their usual operators. Since neither he or the other Navis are used to battling together, Lan cannot bring out their true potential.
* GoryDiscretionShot: Anytime violence ensues in a cutscene, the screen goes black.
* GoshDangItToHeck: Averted in the second game. [[Radar/VideoGames Yeah, that's right]]. Words like "damn", "hell", and "crap" are said, and it ''still'' got an E rating.
* [[GuideDangIt Guide Damn It]]: Compression codes, Variable Sword (and its upgrade Neo Variable Sword), Program Advances, Number Trader codes, EX Codes... let's just say there's a lot of them.
** The ones given via BBS or scattered throughout the game world are generally the easy ones (such as the Zeta/Giga-Cannon, a bulky P.A. that can be reasonably obtained before the first boss), but you'll need a guide to figure out some of the more advanced things (such as all the codes for the Neo Variable Sword). Many codes may be found in guidebooks, trading cards, anime episodes, merchandise, box art, and in one case in ''4'', the first ''VideoGame/{{Boktai}}'' game (through a riddle in the ''[=BN4=]'' game world). Worse, this is only reliable in Japan. Many materials (such as most of the anime codes) are NoExportForYou. You're surprised, Capcom, that they're all over the internet?
* HandInTheHole: Lan has to put his hand in the mouth of a stone lion face to prove that he was a tournament participant in ''4''. If he wasn't, it would bite his hand off.
* HardWorkHardlyWorks: Tora lets on in ''3'' that Chaud spends ten hours a day training. Guess who's smacking who around on a regular basis.
** In the first game, Lan suggests that the PowerOfFriendship enables him to win, as his fighting ability is determined by the strength of the bond with his Navi [[spoiler:and twin brother]] [=MegaMan=], while by contrast, Chaud's [=ProtoMan=] uses his own chips and fights alone.
* HeelFaceRevolvingDoor: Baryl and Colonel.EXE.
* HeroBall: Lan holds it in the fourth game. He'd win over half of his tournament battles by default if he simply just stayed out of his opponents' lives.
* HeroicRROD: What happens to Mega Man in a battle after using Beast Over in ''6''; Beast Over is accessible when you're trying to do a Beast Out (his regular transformation) after the 3 turns limit is over.
* HeroAntagonist: Geo from ''[[VideoGame/MegaManStarForce Star Force]]'' is set to be this in ''Operate Shooting Star'', at least to begin with.
* HijackedByGanon: Of course. [[spoiler:The plot of ''the entire second game'' is revealed to have been hijacked by Wily all along in the third game, and he hijacks the fourth and fifth games with the revealing he's Regal's father.]]
* HollywoodHacking: played with. Sometimes getting into a secure area simply involves obtaining a security certificate. Sometimes, you have to destroy or disable components of the security system to proceed. Other times you have to figure out the password using hints left in the system, solve puzzles, obtain specific Battle Chips, or fulfil other conditions.
** HighlyVisiblePassword: From your Navi's point of view, passwords are easy to decipher. Justified in that your Navi is directly connected to the network/systems and is most often in the correct dataspaces to see/manage passwords for you.
** ThePasswordIsAlwaysSwordfish: The passwords are very often all too easy to figure out, as helpful programs give a ''lot'' of hints.
* HollywoodMagnetism: Justified, as this takes place in the cyber world, where the rules of physics are constructed of data and are therefore artificial. There's a chip called [=MagLine=] which pulls you to the panel(s). If the panels are in the lower row, the staying in the upper row will prevent it from dragging you to that panel and visa-versa.
** Also, the Battle Chip of Magnetman EXE uses his North-South Tackle, and will not work if there is no room to summon South.
* HonestAxe: Spoofed in ''6'' with an absent-minded Mr. Prog spirit of a bucket with "Legendary Spring" scrawled on the side.
* HopelessBossFight: [[spoiler:Forte/Bass.EXE]], in the third game.
** [=ShadeMan=].EXE in the fourth... at least until you're given a Dark Chip as a DesperationAttack.
* IdiotBall: Gets passed around by various characters in the series, at least in terms of IT security. While repairmen slipping in malware attacks and some particularly nasty cases of social engineering are a standard form of espionage, some of the staggeringly blatant security weaknesses in the Internet as portrayed in the game fall into this territory. No wonder [=NetCrime=] is all over the place in the series.
** On the Social Engineering front: Lan should have at least gotten someone to vet the "packages" of malware Mr. Match asks him to install in the [=SciLab=] intranet during the "Hero of ACDC" story arc in [=MMBN3=]. What he does instead: gets his ego manipulated by Mr. Match into blindly loading in the payloads, resulting in a disastrous fire that injured many researchers including his father. To be fair, Mr. Match at least orchestrates an elaborate gambit with planted WWW "agents" to deceive Lan into believing that he had reformed.
* IncrediblyLamePun: ''3''[='s=] Humor program. So many horrible puns from [=MegaMan=].
** Also, in ''3'', there is a recycle canister with a kangaroo shape. In game text? "(used for recycling cans) maybe we should call it the [=CANgaroo=]? ... We apologize for that last joke. It wasn't punny at all." The game apologizes for a pun, even if it is making another pun in the process.
* InevitableTournament: Just about every single game save the first, second, and fifth have some sort of tournament at one point in the game.
** The fourth game had ''three'', and the ''Battle Chip Challenge'' SpinOff had... a lot more.
*** It could be argued that the tournaments themselves ''are the fourth game''.
* InNameOnly: A lot of the Navis share the names of Classic series bosses, but look, act and fight nothing like them.
* InsaneTrollLogic: Green Land in [=BN6=] runs on it, ironically it is said to be a very closed-in and highly regulated society. Two choice laws include the punishment for hitting a Mr. Prog on the head is "something infuriating" (exact words), while the punishment for finding zenny on the ground but not reporting it is tickling. Their entire justice system is overseen by the [=JudgeTree=], a supercomputer built into a giant tree that acts as judge in all criminal cases, which they consider superior to human judges as they might make mistakes. However, this is a world where EverythingIsOnline, and even the prosecutor mentions the tree is constantly targeted by hackers and their system is ruined if it gets compromised.
** Speaking of which, the punishment for tampering with the [=JudgeTree=]? "Ten hours of zapping." That's right. [[ColdBloodedTorture Ten straight hours of constant electrocution.]]
* InsideAComputerSystem: Almost ''everytime''.
* InterfaceScrew: The confusion effect from ''3'' onward, but most egregiously [=VideoMan=]'s scenario in ''4''.
* InventoryManagementPuzzle: From the third game onward, the series feature the Navi Customizer. You can use a number of programs to give Mega Man benefits with five rules: Textured programs may not touch the Command Line, non-textured programs must touch the Command Line, programs of the same color may not be touch, there must be no more than 4 colors of programs, and all used programs must fit within the allotted space. If you make a mistake, [=MegaMan=] will have [[InterfaceScrew glitches]] during battles.
* InvincibleMinorMinion: Quite a few enemies are invincible without exploiting a weakness.
* {{Invocation}}: "Battle Operation, set!" "In!" and "Plug-In! Rockman.EXE, Transmission!" in Japanese; "Battle Routine, set!" "Execute!" and "Jack-In! [=MegaMan=]! Execute!" in English.
* JustKeepDriving: Averted - the cars actually stop when you step out into the street. The first game even has a section with functioning traffic lights.
* KarmaHoudini: Match, who is the only tertiary character to appear in all six games (except ''5'') plus {{spin off}}s.
** There is also [=ShadowMan=]/Dark, something no one even mentions when he appears as a teammate in ''5''.
** Ditto for a lot of the teammates in ''5'' and some of the link Navis in ''6''.
** [[spoiler:Sean]] started [[spoiler:a syndicate, whose activities border on terrorism, including hijacking airplanes and blowing up dams.]] He's out in less than a year due to having a FreudianExcuse.
** Wily, [[spoiler:having personally started 3 terrorist organizations and masterminding the creation of a 4th]], actually gets punished with jail time when he is finally caught, [[spoiler:but somehow, despite being a notorious criminal with a knack for computers, manages to build ''two'' [=AIs=] while in prison.]]
** ''6'' shows the punishment in the game's universe, although it's bordering on torture (100 hours of zapping, waiting 10 hours for the use of a rest room) takes place in a fairly short time.
*** That's just in Green Town, which can only be described as weird even by the series's standards.
** Every single opponent you fight in ''Battle Network 4'' that commits a crime seems to get off the hook one way or another. Including someone who ''makes the temperature in the world go down to the point where it's snowing in a naturally hot country'' and someone who ''depletes their own village's only water source''. The former is seen in Sharo (despite being imprisoned in Netfrica) around the end of the game, and the latter is immediately forgiven after the battle with him.
* KillHimAlready: Upon confronting the devious operator behind whatever catastrophe was occuring, Lan often jacks into an infected computer system to fix things while the human villain, who is often in the same room, just... stands there... watching... Stopping him would be as easy as running up and yanking out some cables, but nope. No dice.
** Justified in that Navis can have operations preprogrammed into them; the only real way to stop something bad from happening is to do enough damage to the Navi that they can no longer carry out the function - often this requires deletion. They discuss this in ''Network Transmission'' [[spoiler:when Mr. Match comes around looking for [=FireMan=], who was [[BrainwashedAndCrazy infected]] by the Zero Vaccine, and the heroes point out that Match could have just told [=FireMan=] to go crazy and burn everything instead of doing it directly. They learn about the faulty Vaccine later.]]
* KnightOfCerebus: [=ShadeMan=], if you think about it. And he's the fricking FIRST boss in ''4'', which is where this applies. When you first see him, he's just floating in a corner, being creepy and creaking to himself, when you leave and come back, people are screaming, Navis are DEAD ''everywhere'' (not deleted, DEAD), and now that he's speaking in sentences, he tells you with perfect manners that he's off to find a nice lady Navi for dessert. As in, one of the main characters' love interest. GetBackHereBoss, indeed.
* LawOfConservationOfDetail: If you see any character with a unique sprite, expect said character to do something major very soon.
** Subverted with [=LarkMan=] in ''[=BN5=]'', as he's an optional boss.
** Also subverted in ''4'', as you end up picking fights with a few generic and heel navis. There's also the tournament announcer that has a unique sprite.
* LargeHam: [[http://www.youtube.com/watch?v=0jsOAnG341U Oh, God]], Colonel.
* LaserGuidedAmnesia: At the end of ''[=BN5=]'', [[spoiler:Wily erasing the memories of his own son Regal so the latter's vendetta against the world will be over]].
* LetsYouAndHimFight: In ''Operate Shooting Star'', [[spoiler:When Roll is kidnapped, [=MegaMan=] finds ''Star Force'' [=MegaMan=] near a clock and fights him. After the fight, they find that [=ClockMan=] is their enemy.]]
* LittlestCancerPatient: Mamoru in ''[=BN3=]'', complete with IncurableCoughOfDeath, who suffers from the same heart condition as [[spoiler:[=MegaMan=] back when he was Hub Hikari]]. He's also the operator of [[spoiler:[[BonusBoss Serenade]]]] and owner of [[spoiler: the Undernet.]]
* LivingShadow: The Shadow and Nightmare virus series, which can only be harmed with swords. Also, any battle against [=DarkMega=].
* LoadsAndLoadsOfCharacters: Being an RPG, this was inevitable; it wouldn't be a stretch to say the ''Battle Network'' games have more characters than any other ''Mega Man'' series.
* LostInTranslation: In the third game, Mamoru's last name is "Ura," and the inn in Yoka is the "Ura Inn." "Ura Internet" (with "Ura" roughly translating as "reverse side", or "underworld"), is the Japanese name for the Undernet, so the names of Mamoru and the inn are meant to hint to Mamoru's connection to the Undernet, and the entrance to the Secret Area being located somewhere inside the Inn's grounds.
** In ''Battle Network 2'', the Netmafia Gospel's ultimate goal is to create copies of Bass, whose name in Japan is Forte. To Japanese players, Gospel's name would be a huge tip-off, since that was the name of Forte's support unit in [[VideoGame/MegaMan the original games]]. In America, they translated Forte to Bass as always, but left Gospel's name alone, confusing the hint. Perhaps they thought that "Treble" would be an odd name for an evil shadowy organization, or they didn't want to bother with their logo, which is a "G".
* MadeOfIron: Let's take a look at Dr. Wily's for a moment...
** ''[=BN1=]'': Wily was at the center of an explosion that leveled his lab. He was just fine in time for ''[=BN2=]''.
** ''[=BN3=]'': He had his soul devoured by an internet EldritchAbomination and his lifeless body was at the center of an explosion strong enough to sink a small island. Since he was on a small island, it sunk, along with his lifeless, blown-up body. He got better in time for ''[=BN5=]''.
** ''[=BN5=]'': [[spoiler:He walks into a room that is currently exploding (the room is the center of the explosion, naturally) in the crater of a volcano that is simultaneously erupting. This does not faze him at all, and he's back in time for ''[=BN6=]''.]] Though admittedly, everyone managed to escape, including [[spoiler:Regal himself]], so it's safe to say that he's okay.
** ''[=BN6=]'': He is at the center of an explosion that levels a sizable chunk of town. Not only did they find his body in the exact spot he was standing (again, at the center of an explosion that leveled a sizable chunk of town), but according to Lan, "he wasn't hurt very badly."
** Keep in mind, Wily is an Old man with a walking stick, and he ''still'' survives all of that.
*** Conclusion: Wily is Immortal.
* MascotMook: Mettaurs. They'll even appear in the later games as an overworld placeholder for virus battles that DON'T involve Mettaurs.
* MatrixRainingCode
* MaximumHPReduction: A slightly weird version occurs with the Dark Chips in the fourth and fifth games. They deplete the ''user's'' maximum HP by one point.
* MeaningfulName: [[ShapedLikeItself HeelNavi]].
* {{Mon}}: Experimented with in ''3'' and ''6'', in which [=MegaMan=] could domesticate and summon viruses through chips (the former) or copy them for tournament battle (the latter).
** You could even feed them in ''3''.
** Also, the Navis themselves.
* MonsterClown: [=ColorMan=] and [=CircusMan=]. ''Especially'' [=CircusMan=].
* MoralityChain: Subverted. [[spoiler:Wily momentarily stops his quest for revenge for the sake of an old friend. That friend goes to war, leaving his son (Baryl) in Wily's care. When Wily learns that his friend died in battle, his thirst for revenge returned.]]
* MusicalNod: One that stands out is from the credits sequence of the fifth installment; you may be pleasantly surprised by the sudden appearance of the opening riff from the first three games.
** You can also hear it in the background of the "Hometown" theme from the same game.
* MythologyGag:
** Bass.EXE gives one in the second game, for all those people who know his Japanese name.
--->'''Bass.EXE''': [[{{Pun}} Battle is my forte!]]
** Lan's grandfather and stand-in for the Classic series' Dr. Light is named Tadashi Hikari, which translates to "right (i.e. correct) light". Probably a play on the whole [[SpellMyNameWithAnS Right/Light problem]].
* NegativeContinuity: Pretty much every game rebuilds the continuity from the ground up with little regard to past games. Of course, there are some {{Continuity Nod}}s here and there too.
* {{Nerf}}: The series tends to seriously nerf or completely take out [[GameBreaker game-breaking]] battlechips and strategies while introducing new battlechips or seriously buffing others to said game-breaking levels.
* NewGamePlus: The fourth game is the only ''Battle Network'' game that features a true form of this, allowing you to do this as many times as you want. The second game features a separate save file with upped difficulty that has major amounts of GuideDangIt involved in unlocking it, and all of the other games save for ''4.5'' are generally one playthrough and one save file only deals.
** Although, in 4, if you want 100%, or even if you just want the various other [=DoubleSouls=], you have to beat the Game, the New Game Plus, and the New Game Plus '''Plus'''. And in every single playthrough, you have to go through some of the most irritating minigames and pointless backtracking over and over, and over again. The New Game Pluses don't even get rid of tutorials! (see HeKnowsAboutTimedHits.)
* NewYearSameClass
* NiceGuy: In the sixth game, one scenario's villain claims Lan's FatalFlaw is that he is too nice. Lan's response?
-->'''Lan''': "Being nice is a good thing!"
** Aside from that, though in the first three games occasionally gets a little cocky, throughout the entire series Lan is ridiculously nice and forgiving, to the point that at the end of the sixth game he forgives [[spoiler:''Wily'']].
** CharacterDevelopment. The kid had a FreakOut and a RoaringRampageOfRevenge in 3, remember?
* NoExportForYou: ''Rockman.EXE 4.5'' has not been released outside of Japan as of May 2009, and will probably never be. Also, almost everything related to ''VideoGame/{{Boktai}}'' (which included a ton of post-game content) was removed from the English version of the sixth game. [[SeriousBusiness Cue the very ticked off fans that knew of this.]]
** Heck, what about the Battle Chip Gate and its successors? Releasing those would have made collecting physical battle chips totally worthwhile.
** And what about the e-Reader cards Japan got to use with ''Rockman.EXE 4''-''6''? Heck, everything related to them was translated then DummiedOut in ''Battle Network 5''!
** Not to mention Phantom of Network and Legend of Network.
** It looks like the ''VideoGame/MegaManStarForce'' crossover/remake of ''Battle Network 1'', ''Operate Shooting Star'', isn't coming over either. It's been out in Japan for several months and no word of a translation.
* NoobCave: Typically ACDC Area. In the one game where it's not, it's revealed the reason why ACDC area usually has such weak viruses is because [=MegaMan=] clears out the area so often that the only viruses that could form were small ones.
* NoOneCouldSurviveThat: UpToEleven and straight into ArtisticLicensePhysics territory in ''[=BN2=]''. Lan should have been dead from radiation poisoning before ''Battle Network 3'' if he was exposed to hundreds of thousands of rads, even with a top-notch radiation suit.
** Then again, this is some kind of [[GreenRocks wacky computer-born radiation]] that not only causes someone to walk sideways when he tries to go forwards, and starts merging the real and cyber worlds if left unchecked, so perhaps the usual rules don't apply...
* NotAllowedToGrowUp: The first three games happen during fifth grade, and the final three during sixth grade. The final game ends (before the DistantFinale) on the last day of sixth grade, and the elementary.
** The second game supposedly takes during summer vacation.
*** Justified in Japan, since the school year starts and ends in spring rather than summer. Although it's a PlotHole for those who do not know that.
* NotCompletelyUseless: The Minibomb chips in each of the games are usually one of the first chips a player removes from their initial folder, due to the fact that actually hitting anything with them is like pulling teeth, and it doesn't pack the punch even if it does land. However, in the sidescrolling spinoff, ''Transmission'', it's actually really easy to hit with, and the explosion hits several times for full damage within the space of about a second, meaning one single bomb can destroy almost every random enemy in the game not protected by some sort of aura. It's also easy to get, has a low MP cost, and you can carry a ton with you. For that single game, it is turned from a useless weapon into a complete GameBreaker, but most players will still just skip over it after their experience with it in the main games.
* NotRareOverThere: In ''2'', one NPC asks to be payed in "Guard * chips". Talk to another NPC, and she'll give you 30 of them.
* NumericalHard: The second game has a hard mode which only increases the amount of HP each enemy has and the amount of damage they do.
** So does the fourth, in its NewGamePlus, though the enemies also move faster and have more agressive attack patterns.
* ObfuscatingInsanity: There's an old man NPC in the first game who spends most of the game telling you he's not senile. [[spoiler:He's the one who knows how to access the Undernet.]]
* ObviousBeta: The first game. It's amazing how much was improved upon by just the ''second game''.
** Justified in that the first game was Capcom figuring out the question of how the battle system and mechanics should work in the first place.
* ObviouslyEvil: Dr. Regal, so much so that he wasn't really trusted even in his [[VillainWithGoodPublicity not-entirely-negative publicity]] days. Pretty much every evil Navi follows this trope as well.
* OddlySmallOrganization: The number of unique characters in World Three shrinks as the series goes on. As a consequence, their influence goes from being feared throughout the world in the first three games to being hardly noticed until (and arguably after) they release the SealedEvilInACan in the sixth game.
* {{Ojou}}: Yai. Maybe also Jasmine.
* OldSaveBonus: The DS version of ''Battle Network 5'' allows you to plug any of the previous GBA games in the series (including the GBA versions of ''Battle Network 5'') into the system's second slot for various bonuses, including a special form (Bass Cross) that was previously restricted to the Japanese games.
* OneGameForThePriceOfTwo: third game onwards.
* OnlyPointTwoPercentDifferent: Lan and [=MegaMan=] have a 0.1% difference in their DNA, due to [=MegaMan=] [[spoiler:being a program designed after Lan's dead twin brother, Hub]]. However, [[spoiler:this is changed to a 0% difference between the two at the end of the first game, making the two have exactly the same DNA.]]
** This is all despite [=MegaMan=] being a ''computer program''.
* PauseScumming: Battling the Pop-pup enemy plays like a game of whack-a-mole, so pausing lets you spot him without the need for lightning fast reflexes. The fight with Drillman.exe is similar.
* PetTheDog: Just to show how much different the Wily of this universe is from the original, he [[spoiler:paid for the medical treatment of Joe Mach's daughter]], and [[spoiler:his adoption of Baryl, which even caused Wily to temporarily abandon his plans of revenge]].
** Although the first one was, in all likelihood, simply a way to get [[spoiler:Mach]] to work for him in the first place.
* PhlebotinumRebel: In game five, [=MegaMan=] is captured and infused with a conscious Dark Soul. Unfortunately for Nebula, Lan gets [=MegaMan=] to wake up and take control of himself - which unlocks the [[SuperpoweredEvilSide Chaos]] [[SuperMode Unison]] ability, letting you use the [[GameBreaker Dark Chips]] as much as you want. Be very careful, though, as if you mess up trying to control it, your Dark Soul will hop out and start taking shots at you.
* PinkGirlBlueBoy: [=MegaMan=] and Roll, [[http://www.rockman-exe.com/rr.html these pictures]] should explain it.
* PostCyberPunk
* PowerCopying: It wouldn't be a [[TropeNamer Mega Man]] game without it. Played straight in several ways, actually, with Souls/Crosses and [[FightLikeACardPlayer Chips]].
* PowerLevels: There are various systems that show up in different places throughout the series. (However, that has no bearing on a given character's particular SuperWeight).
** [[{{Mooks}} Viruses]]: In the first three games, viruses in general form a three-tier system, with an increase and PaletteSwap between levels; under certain circumstances (usually plot-related), you can happen across a special "Omega" virus, generally [[LawOfChromaticSuperiority Black]]. The fourth and fifth games forego the "Omega" virus and instead give each of the three levels an "[[SuperMode EX]]" variant[[note]]Although you may see some similarities between high-level EX viruses and Omega viruses, don't confuse them. Mettool Omegas will launch superfast shockwaves that crack panels beneath them. Mett3 EXes will launch superfast shockwaves that corrupt the panels beneath them into swamp panels.[[/note]]. The final game returns to the three levels plus Omega variant, though instead adds two levels of "Rare" that jockey for prowess with the Omega variant[[note]]Defeating Rare Viruses will add virus data to [=MegaMan's=] Virus Battler Card for later use[[/note]].
** [[BondCreatures NetNavis]]: Like viruses, Net Navis can generally be counted on to follow a three-tier "version" system. In the first two games, most [=NetNavis=] will reach version 3. In three, "V2" and "V3" are replaced with α and β, and we are also given a [[GuideDangIt secret]] class called "Omega" (Ω). This remains the same for the fourth and fifth games, which replace Omega with a "Dark Soul" variant, basically the given Net Navi at the height of their power... ''[[SuperPoweredEvilSide plus]]'' the [[TheBerserker wild craziness]] of [=MegaMan's=] Dark Soul, which also gives them access to every Battle Chip and Program Advance you've ever used, with their frequency depending on how often ''you'' use them (you haven't been spamming any Program Advances, have you?)[[note]]Don't worry, you won't have to worry about Dark [=NetNavis=] until after you [[FlawlessVictory S-Rank their original third versions[[/note]]. The sixth game replaces the α and β with EX and SP, and its special class is "R". ([=ProtoMan=] has a secret "FZ" class that otherwise fills the same niche as "R").
*** You can generally earn benefits for [[FlawlessVictory S-Ranking]] the third variant of a given [=NetNavi=]. In ''3'', for example, various security cubes will unlock depending on which Navis you've defeated.
*** Interestingly, while you can generally count on seeing the various villainous [=NetNavis=] make a reappearance (which would be the [[AlternateHistory Battle Network]] version of the [[VideoGame/MegaMan Wily Castle]] BossRush, though spaced out by plot); most [=NetNavis=] won't actually exceed the second level in-story. However, the original defeat of a [=NetNavi=] will rip off enough raw data, that the data's natural restoration will occur anyway, and take in various leftover data from the internet to reinforce the leftover data, resulting in a second, stronger "Ghost Navi", often caught in a single place. Defeating ''that'' Ghost will release it to roam another area, and NPC chatter that tips you off that the ghost is roaming around will often imply the ghosts are retaining facets of their [[GeneticMemory originals' personalities]].[[note]][=BubbleMan's=] third-level ghost refuses to fight you unless your health is critical; and can ''still'' hide among the legions of Aqua viruses, so using the "[=FishBody=]" program to draw him out won't work.[[/note]]
** Battle Chips actually employ multiple tier systems at once. In the first two games, most chips can be used however many times as the max cap will let you, but you can only have five unique Navi chips max (and Navi chips can often be split into three variants; the various versions of a Navi Chip don't count as repeats). In the third game, they codified it into the "Standard", "Mega", and "Giga" tiers that lasted throughout the series and VideoGame/MegaManStarForce; "Mega" absorbed the Navi Chips. However, it added a secret fourth version of each Navi chip that could only be earned with [[ThePowerOfFriendship Team Style]] and a number of overpowered earlier chips and applied the Navi Chip limit of five uniques to all of them. The "Giga" classification included only the strongest, most often employing certain [=NetNavis'=] [[SignatureMove Signature]] or [[FinishingMove Finishing]] moves, or perhaps even single Navi Chips of the most powerful [=NetNavis=] (and in 3, the [[SerialEscalation 5th]] version of a Navi Chip). Also, fairly standard for the whole series, was a five-star classification that rated a given Battle Chip's power in relation to others. Most standard chips would rank one, two, or three stars; most Navi chips would rank three, four, or five stars.
* PromotedFanboy: Some of the Custom Navis featured in the game are actually fan submissions for the "create your own Navi" contests held throughout the series. Many are [[BonusBoss extra bosses]] (especially ones owned by Mr. Famous), but several, like [=LaserMan=].exe, [=Cosmoman=].exe, and [=CircusMan=].exe are canon bosses.
* PressXToNotDie: In [=PvP=] play, you can counter the other player's time-stopping weapons, even things like the [[PenultimateWeapon V5 Navi Chips]] in ''[=BN3=]'', just by pushing A at the right moment to [[CatchAndReturn call your own ally]]. You have to set up a Battle Chip for this in advance, however.
* [=Pre-=]TeenGenius: Slightly even younger, Chaud, around the same age as the other main characters, is a high-ranking Official (a sort of Network policeman), and by the end of ''[=BN6=]'', while the others graduated elementary, he graduated '''high school'''.
** That last part's not really all that far-fetched in the US, in a strange inversion of DubInducedPlotHole, since, strictly speaking, receiving a GED 'counts' as completing high school, and an individual could conceivably pass the GED test with an average 8th grade education. (There's a reason it's called the [[FanNickname "Good Enough Degree"]].
* PsychopathicManchild: The leader of Gospel finds himself exasperated as all of the people in his organization are continually being thwarted by a[[spoiler:nother]] child. Heck by the time you get to [=ShadowMan's=] chapter, you can tell he's psyched to be hiring a professional. [[spoiler:Of course, then you find out [[SubvertedTrope who he really is]].]]
* PunnyName: Starting from Lan (a de-capitalized acronym for [[http://en.wikipedia.org/wiki/Local_area_network local area network]]) and going damn near everywhere: Mayl, (rolo)Dex, ''[=BN5=]''[='s=] Fyrefox, [[spoiler:Hub]]... and that's just the ones derived from computer and networking terms.
* ThePowerOfFriendship: Everywhere; Souls from the fourth game onward are a more direct application.
* QuirkyMinibossSquad: The team of Yukia, Ito, Vic, and maybe Blackbeard during the last quarter of ''6''. They are actually quite competent and pose a serious threat to the main cast, despite having squabbles like whether or not they should call themselves Yuika's Lovelies, the Cloudy Bombers, or the Justice Club.
* RandomEventsPlot: Many of the chapters seem to be this, for better or worse. Many of them share a unified theme, mind you. In 1, each chapter is a different terrorist attack staged by a [=WWW=] operative (serial arson, corrupting the water supply, several nigh fatal hostage incidents), each of which disguises a theft of a superprogram utilized in the creation of the Life Virus; 2 and 3 are more of the same, with even more terrorist plots (another hostage situation, terrorist demolition, mass [=NetNavi=] murder, etc), also serving the purpose of stealing program data. The fifth game shakes this up by rendering each chapter as a campaign to recapture lost cyberworld territory, while the 6th returns to [=WWW=] form.
** The 4th game is the straightest example of this trope, however, as each sub-chapter is ''determined randomly''.
** Lampshaded in the sixth game:
--> '''Lan''': It's OK. I'm used to random things happening by now.
* RealityEnsues: Several disasters over the course of the series show more or less the consequences of hooking up critical computers to the Internet without sufficient security measures, and they naturally get hacked by the villains.
* RecurringRiff: The main theme is both types.
* ReplacementGoldfish: Variation: [[spoiler:[=MegaMan=] is Hub, Lan's dead brother.]]
* RescueArc: Twice in the fifth game, ''three'' times in the sixth game. Almost all of them involve rescuing [=MegaMan=].
** [=ProtoMan=] gets one in ''4'' (''Blue Moon''), and either he or Colonel, depending on the version, do in ''5'' as well.
* RestoredMyFaithInHumanity: Duo seeks to wipe out mankind because it's wicked (nevermind the fact that destroying an entire planet isn't the most moral thing to do...) but changes after his fight with [=MegaMan=].
* RightHandVersusLeftHand: After you beat [=ProtoMan=] in ''[[http://megaman.wikia.com/wiki/Rockman.EXE_Operate_Shooting_Star Operate Shooting Star]]'' Roll gets kidnapped and all Mayl says is that there was a [[VideoGame/MegaManStarForce weird blue NetNavi with a red visor covering his eyes]]. Lan and [=MegaMan=] confront him and after [[GetBackHereBoss a long chase sequence]] [[LetsYouAndHimFight the two of them fight]]. The thing about this is that the chase and fight sequences could have been avoided if ''SF'' [=MegaMan=] had just told [=MegaMan=].EXE what he was doing in his time period instead of running off.
* TheRival: Chaud
* SealedEvilInACan: Alpha in the third game and both Gregar and Falzar in the sixth game. The sixth game's example is especially notable in that immediately afterwards, one is captured by [=CircusMan=] for the evil organization, and [=MegaMan=] has no choice but to seal the other within his body. Cue [=MegaMan=]'s [[PersonOfMassDestruction series of]] [[IKnowYouAreInThereSomewhereFight internal]] [[FightingFromTheInside struggles]] while having to deal with the evil organization at the same time.
* SequelHook: The scene from ''[=BN2=]'' after the end credits.
* ShoutOut: A corrupted program in the first game says, "[[ZeroWing All your base are belong to us]]"
** Also, One of [[spoiler:Cossack]]'s inventions, a [[spoiler: chair that can transport a living person's mind into cyberspace, although with risk of leaving a person brain-dead or worse if his/her mind was killed in cyberspace]] bears a lot of similarities to the Jack-in chairs from the ''[[Film/TheMatrix Matrix]]'' trilogy.
** Incidentally, the phrase "Jack-In" was used in the original ''Matrix'' prior to its use in the original ''Battle Network'' (the English versions; the Japanese versions uses "plug in").
** It's well-hidden, but if you like exploring areas between chapters, you might find an Aquarium worker hanging out with the jellyfish in ''[=BN6=]'' - he even introduces you to two of them: [[LeeroyJenkins the one on the right is named Leeroy, and the one on the left is named Jenkins]].
** In the second game, [[http://lpix.org/572354/image564.png there's a Game Cube logo in the scenery for the Scilabs' Mother Comp. where you fight Shadowman.]]
* SiblingYinYang: Netto/Lan and Saito/Hub.
* SituationalSword: Machine Sword, which only hits paralyzed foes.
** A ''lot'' of the more powerful Battle Chips are these (Snake and Old Wood, for example, both require holes in the field, but in different ways). A lot of the MetaGame folders (look up the Renowned Folder [=FAQs=] on [=GameFAQs=]) are based in producing the situation to get the sword, and then boosting it with as many Power chips as they can get.
* SmugSnake: [[spoiler: The Mayor in the sixth game]]. He wanted to be the final boss, but was hopelessly out of his league and was outplayed by both sides.
* SpellMyNameWithAnS: Is it Mayl, Maylu, or Meiru?
* SpinOff / SequelSeries: ''[[VideoGame/MegaManStarForce Star Force]]''.
* SpinToDeflectStuff: Used by [[TrickBoss Serenade]], who, as a graceful jerk, sends back the large majority of your attacks right back at you without even taking a scratch. Aside from the "attack when Serenade is attacking you" tactic, there is a less obvious way to completely bypass this defense.
* StockVideoGamePuzzle: The weighted switch variety in ''5'', in each of the factory computers.
* StoryBreakerPower: It is implied throughout the series that [[spoiler:should [=MegaMan=] ever completely tap into his latent powers from his human side as [[ReplacementGoldfish Hub Hikari]], he would gain powers that would make it seem as if he was the strongest being on the Internet, if not an actual god of it.]]
** [[spoiler:You can play with a ''[[GameBreaker fraction]]'' of that power with Hub Style in ''2'', the Navicust Program Hub.BAT in ''3''-''5'', and the Gigachip Hub Patch in ''6''. All but the last cut his max HP in half but grants [[AllYourPowersCombined almost every non-HP-increase passive ability at max power]].]]
** [[spoiler:However, we finally see [=MegaMan=] unleash his full power in a cutscene at the end of ''5'', where he completely transforms into his human form and seals the (thought to be defeated but had quickly recovered) ''final boss'' Nebula Gray (which is ''[[MadeOfEvil the personification of evil and darkness]]'') with a simple ''wave of his hand''.]] Of course, everyone quickly forgets about this by the time the sixth game rolls around.
* SuperArmor: Available as an equippable ability, which renders the user immune to flinching (and knockback) when struck by attacks.
* SwissArmyAppendage: Net Navis often replace either or both of their arms with the weapons pictured in assorted Battle Chips, sometimes with [[ArmCannon projectile weaponry]] or [[BladeBelowTheShoulder entire blades]]. ProtoMan and Colonel are notable for using a sword whilst occupying [[TelescopingRobot Copybots]].
* {{Synchronization}}: All over the damn place as soon as ''[=MMBN1=]''[='s=] ending happens. And of course, the Full Synchro.
* TechnologyMarchesOn: Character and chip names are limited to 8 characters. The network must run on DOS at the time.
* TheSyndicate: Nebula was mentioned in ''4'' in one of the first plot-related cutscenes, and expounded upon by Chaud directly after the dungeons from hell. They're responsible for the plots of the fourth and fifth games.
* ThemeMusicPowerUp: "Running Through The Cyber World"/"Proof of Courage", "Under Justice"/"You're Not Alone" and "Hero".
* ThemeNaming: As usual, the Navis with names go with the SomethingPerson formula of the [[Videogame/MegaMan classic counterpart]], barring a few such as Bass or Serenade.
** Applies to some of the human characters as well, with a recurring theme of computer-networking-related terminology (Lan from LAN, or Local Area Network; Hub as in "network hub", a connection point where multiple devices can connect to a single network; Mayl as a corruption of "mail", as in e-mail; etc.).
* TooDumbToLive: In the first game, during the water-works scenario, someone who's incredibly thirsty walks right up to the school pond and takes a drink...never mind that one, he is drinking ''from a fountain'' that likely has a completely different filter than water taps, but it's also ''purple''.
* TookALevelInBadass: Post-''[=BN3=]''
** The Good News: Bass no longer uses his Life Aura.
** The Bad News: Bass no longer '''needs''' his Life Aura.
* TournamentArc: Present in a few games; makes up almost the entirety of ''[=MMBN4=]''.
* TrailersAlwaysSpoil: Not that ''Sun'' or ''Moon'' tried to keep the BigBad much of a secret, but [[http://www.youtube.com/watch?v=60DKt7N_FEY this trailer]] still doesn't help things.
* TransformingMecha: [=GyroMan.EXE=].
* TwinTelepathy: Guess who? [[spoiler:Answer: Lan and [=MegaMan=].]]
* TwoTeacherSchool: All games, the 3rd and 6th show addition teachers, but only one of Lan's teachers is ever shown.
* UnexpectedGameplayChange: The liberation missions in the fifth game are more or less board games. Navis each get a turn to move through the area and "liberate" tiles by defeating an enemy party within three turns. The player liberates tiles one by one to clear a path through the impassable "dark" tiles to the boss. Upon beating him you get a reward based on how many rounds it took you to clear the area. To say the premise is a slight change-up from the normal gameplay is an understatement.
** Also, battles during Liberation Missions are modified, as well. First, battles are now timed. You have exactly [[RuleOfThree three]] turns to defeat the enemies or the boss - the instant the Custom Guage is filled, the menu shows up. One turn down. If enemies are still left, that [=NetNavi=] ends his turn without having achieved anything (thankfully, bosses will retain the damage dealt over several Liberation battles). This is made all the more difficult by the fact that, depending on how you start your battles, territory changes will factor in. You can literally be stuck in the center two columns with enemies on either side, which is made even ''WORSE'' with enemies that can warp around their territories. Have fun!
* UnwinnableByMistake:
** In ''2'', you can't jack out of [=QuickMan=]'s stage once you enter. Jacking out is the primary method of restoring HP, and it also cuts you off from accessing better chips, making getting stuck here ''very'' possible.
** During [=WoodMan's=] scenario in ''Battle Network 4: Blue Moon'', the area will fail to load ''any time you leave a random encounter unless you're playing on an original [[GameBoyAdvance GBA]]'' (that includes not just emulators, but the SP, Micro, and Gameboy Player). Technically, its load-time just slows WAY WAY WAAYYY DOOOWWWWNNNNN... If you're willing to wait, oh, say half an hour, it'll show up again. The problem also shows up if you try and SAVE.
*** An even worse example of this from 4 is the Free Space battle board. If you link up with the other version before you have all 6 of the double souls (this means a new game plus plus at the very minimum) then your game will crash and be completely broken. You can't start a new game or do anything to remedy it.
** A similar slowdown error caused by similar platform problems occurs in either version of ''4'' if one uses a [=GutsMan=] chip.
* UpdatedRerelease: ''Operate Shooting Star''.
** ''Double Team DS'' as well. You still play one version of the game but with better music and some additions.
** The third game also is an example of this in Japan with ''Black'' (''Blue'' in the US), as it was released three months after the glitchy mess that was the original version of ''Battle Network Rockman.EXE 3''.
* VampireRefugee: [=MegaMan=] himself in ''5''. [=MegaMan=] was infected so heavily he spawns a Dark Soul, which later gains intelligence. He manages to [[HeroicWillpower subjugate it]], which gives him access to the [[SuperpoweredEvilSide Chaos Unison]], every use running a constant risk of releasing said Dark Soul.
* VerbalTic: Most prominently, Higsby with his trademark "huh", a few of the Navis also do this, such as [=DiveMan=] with "Aooga" and [[strike:Aqua]] [[strike:Spout]] Aquaman and * woosh* or "drip" for the fourth and sixth games, respectively.
** Even more prevalent in the Japanese version. Higure (Higsby) has "demasu", [=BubbleMan=] has "puku", [=GutsMan=] has "gatsu", and so on.
** [=BubbleMan=] has a lot of bubble-variant tics.
* VeryDefinitelyFinalDungeon: Let's see, A base isolated in the mountains, an irradiated condominium, an evil-looking castle on an island, a foreign internet network inside an asteroid, and yet another evil-looking building in the middle of a volcano...
** The only ''EXE'' game that actually tried to hide this is ''6'', and even then, you will figure it out after listening to it's [[MusicalSpoiler suspicious music]] and when the BigBad appears and reveals his EvilPlan. It was an innocent-looking area that can be accessed about ''five seconds'' after leaving from Lan's house.
** [[spoiler:Kotobuki's]] cyber world also tried some subtlety. It has bright colors and everyone there is nice... but if you look well, [[spoiler:Koto Square]] ''is shaped like a skull'' and has a mysterious blocked darker path. Just before the reveal, you discover that the [[spoiler:Koto]] area is connected to the Undernet. [[StealthPun Also, people pray in there.]] [[spoiler:"Gospel", [[DontExplainTheJoke get it?]]]]
* VictoriousChildhoodFriend: [[spoiler: Mayl.]]
* VirtualGhost: [[spoiler:Hub/[=MegaMan=]]]
* VirtualCelebrity: Aki-Chan from ''NT Warrior''
* VisualInitiativeQueue: The Chip Challenge is based on this.
* WakeUpCallBoss: [=ProtoMan=] in the first two games can be considered this.
* WeatherControlMachine: Made important in ''2'' when the computer suppressing the planet's weather is hacked, threatening to unleash years' worth of earthquakes and storms on the planet.
** Rehashed on more localized scales in ''4'' and ''6'', natch. In these cases, however, the real-world weather disruption is part of that chapter's boss Navi's schtick (in ''2'' it's just a byproduct of Net-centric weirdness).
* WellDoneSonGuy: Chaud in ''3''. Not that he'd ever admit it.
* WhatHappenedToTheMouse: There's a mysterious [=NetNavi=] in ''3'' that forges some connection between [=SciLab=], Bass, and Alpha. While the connection between those three entities is expounded, the Navi only appears for all of two scenes and we're never given any sort of closure regarding him..
** Given how he addresses Bass on familiar terms and has some knowledge of his powers, it's quite possible that he's [[spoiler:Cossak]]'s [=NetNavi=].
* WhatIf: The series stems from the question "What if Doctor Light worked in networking instead of robotics?" Meanwhile, Doctor Wiley still worked in robotics, and became fiercely jealous when Light's projects took away his funding and public interest.
* WretchedHive: The Undernet.
* WhyDontYaJustShootHim: While Lan's opponents usually hack systems from out of sight, there are still plenty of instances in which Lan and his (generally larger and tougher) opponent both send their Navis to do battle from within the same room. In the time it takes to traverse a puzzle dungeon, fight through waves of RandomEncounters, and defeat a boss Navi, the enemy operator apparently never thinks to punch Lan out, or something. [[spoiler:They figure this out, but only right before the very end of the series.]]
* YouAllLookFamiliar: {{Lampshade|Hanging}}d at one point.
** Justified in the Internet world, as the regularly reused navis are supposedly "standard" models. They're occasionally used by major characters; similarly, unimportant characters like [=LarkMan=] sometimes have unique sprites.
*** Generally, though, unique sprites designate fightable bosses rather then important characters - using the example from above, [=LarkMan=] is totally separate from the plot, we never see his operator, and yet he has a unique sprite.
*** Also justified: ''4'', ''5'' and both of the spinoffs have "Normal Navis" which are more generic, cheap models, whereas the anime explicitly states that [=MegaMan=] and the others are expensive custom Navis.
** There's a mention in ''6'' from the characters which notes that [=MegaMan=] "looks heavily modified", which possibly factors to the unique models.
* XMeetsY: Classic Mega Man meets KingdomHeartsChainOfMemories (for the similarities in gameplay) meets TheMatrix.
* YouMeddlingKids: Used almost word for word.
