** In this game and ''2'', the Navi Custumizer doesn't exist, instead they have Powerups that only upgrade [=MegaMan=]'s buster.

* SequelHook: The end reveals that [[spoiler:Wily is still alive in the credits]].

* LateForSchool: Lan is late on the second in-game visit to school, and has to sneak into his classroom. He takes the back door, and sneaks to his front-row seat. The class only has nine seats, meaning his absence would be easier to notice.

A Japan-exclusive port, ''Rockman.EXE Operate Shooting Star'', was later released on the UsefulNotes/NintendoDS in 2009. Along with some quality-of-life improvements, this version features a new crossover scenario with ''VideoGame/MegamanStarForce''.

* AccidentalPublicConfession: Mr. Match accidentally reveals that the serial arson he engineered was actually all about getting the [[McGuffin Fire Program]] in Lan's[[note]]Dr. Hikari's[[/note]] oven when he consoles himself over his loss by mentioning he "completed his mission". He immediately realizes he [[LampshadeHanging probably shouldn't have told Lan that]].

** S-Ranking an encounter ''always'' yields a chip drop. Some of the best chips can now be obtained at ranks 8 or higher.

** In this game and ''2'', Navi Cust doesn't exist, instead they have Powerups that only upgrade [=MegaMan=]'s buster.

** The main internet area looks very different than it did in later games -- it's a mostly-incomprehensible maze with a few chip salesmen scattered over it and no real pattern to it, whereas later games tended to make it much more orderly and distinct for each region. Indeed, because the first game had the same background for all parts of the Internet, it's impossible at a glance to tell the difference between the "regular" Internet and the Undernet.

** The existence of AfterCombatRecovery, where [=MegaMan=] will recover all of his HP after every battle. The only exception is the Power Plant where it was presented as a one-time gimmick for the dungeon.

* {{Foreshadowing}}: As soon as you can use the Metro, you're prompted to pay Dad Hikari a visit at work. He's not in, but while you're at the office you can find a photo of his family [[spoiler: revealing that Lan is not an only child]], and talk to some Navis in the large workstation who tell you about an experimental Navi [[spoiler: with human genetic data]].

* SequentialBoss: During the [=ElecMan=] Scenario, Chaud and [=ProtoMan=] finally break through the system protection and appear in the power plant computer where Lan and [=MegaMan=] fought [=ElecMan=]. They reveal that they intended to lure Zap in so they could defeat [=ElecMan=] and secure the [=WWW=] Server data, but [=MegaMan=] and Lan (the amateurs) thrashed him so thoroughly there was no useful data left over. Chaud gets fed up and orders [=ProtoMan=] to delete [=MegaMan=].[[note]]The great irony of the scene is that [=ElecMan=] had already finished his work by the time Lan and Mega arrived in the first place. If Lan and Mega hadn't gotten involved, the [=WWW=] agents would've been ''long gone'' by the time Chaud and [=ProtoMan=] got into the system.[[/note]]

-->"So you've made it this far... It's a shame you're wasted on the outside world..."

** Escaping battles strictly requires the Escape chip. ''2'' introduces the L button as an escape option but retains the chip, while the third game onward remove the chip completely.

* SpaceFillingPath: While present to some degree throughout most of the game, the main internet is a partifularly dramatic example, filled to bursting with loops, dead ends, and paths that twist and turn constantly. This is all made worse by how the paths all look more or less the same, combining with the isometric perspective and small field of view to make it very frustrating to tell where you are and where you're going. Prepare to spend a lot of time wandering aimlessly before stumbling across your destination.

* DiscOneNuke: Fire Tower chips can be obtained as soon as you start the [=FireMan=] scenario, and [=FireMan=]'s battle chip can be obtained shortly afterwards. They do 100 damage which is huge this early in the game, and synergize well with [=FireMan=] since they share an F chip code meaning that if you take time to fill your folder with a few of each, you can easily trounce many early-game viruses in one hit, as well as take huge chunks out of the health of many a boss. They even stay useful in the late game!

* EarlyInstallmentWeirdness: The first ''Battle Network'' is not only an ObviousBeta, but it was still trying to figure out how to hash out the world itself.

** Chip Traders don't autosave.
** Escaping battles strictly requires the Escape chip. ''2'' introduces the L button as an escape option but retains the chip while the next game removes it completely.
** The existence of AfterCombatRecovery, where [=MegaMan=] will recover all of his HP after every battle. The only exception is the Power Plant where it was presented as a one-time gimmick for the dungeon.

A Japan-exclusive port, ''Rockman.EXE Operate Shooting Star'', was later released on the UsefulNotes/NintendoDS in 2009, titled . Along with some quality-of-life improvements, this version features a new crossover scenario with ''VideoGame/MegamanStarForce''.

In the near future, everyone has a personal exploration terminal (PET), and the hero Lan has [=MegaMan.EXE=] as his. Together, they stop cyber crimes, eventually discovering WWW (World Three).

This game completely ditches the previous ''Franchise/MegaMan'' platformer gameplay and instead is an RPG, where Lan gives Battle Chips to [=MegaMan=] who uses them for special moves. The combat is real time and the enemies are viruses.

''Mega Man Battle Network'' is later ported into the UsefulNotes/NintendoDS in 2009, titled ''Rockman.EXE Operate Shooting Star''. This port adds several new features, particularly a crossover scenario with ''VideoGame/MegamanStarForce'' and is unreleased outside of Japan.

* EstablishingSeriesMoment:[=MegaMan=]'s attempt to pass through the oven's cyber-world is impeded by a field of flames. Lan clears the way for him by spraying the real oven in his house (which is also on fire) with a super-soaker. This works.
