History YMMV / MegaManBattleNetwork5TeamColonelAndTeamProtoMan

* ContestedSequel: This game is the most polarizing in the series. While it has better reception than ''Battle Network 4'' -- near-universally agreed to be the weakest entry -- ''Battle Network 5'' still holds onto many of the gameplay changes that occurred going from ''3'' to ''4'', namely the nerfing of Program Advances and gameplay balance focusing on Double Souls and their unique abilities. The story is also better regarded than ''4's'' ExcusePlot TournamentArc, but still not all that great compared to the stories of earlier games. With the PolishedPort taken into consideration, many would put the game at least on par with ''1'' and ''2'', but still below ''3'' and ''6.''

*** Number Soul is just as broken as Search Soul. It automatically gives you ''ten'' chips in the Custom window, making it very easy to get the ones you need to form a powerful combo. It also grants all your neutral chips +10 ATK, effectively doubling the damage dealt by the infamous Vulcan chips. The Soul's only downside is its utterly terrible Charge Shot, but given its combo potential, it's unlikely you'll be using your buster anyways.

** [=NumberMan=] is seen as the weakest member of the Team Colonel cast. His Charge Shot, like Meddy's, is a lobbed bomb, but it also has variable damage with a long windup time and can even whiff if it makes direct contact with an enemy, and his unique chip is not as useful as the others when it is dependent on enemy movement. His Number Check ability can collect items and break traps without putting him into combat, but it doesn't liberate them either. It's generally recommended to switch him out with [=SearchMan=] in ''Double Team DS'', as [=SearchMan=] can liberate entire lines of item and trap panels and is a bit more competent in combat.

** Flinching. An overwhelming amount of chips in this game give the enemy invincibility frames upon connecting, pretty much making it mandatory to have Blinder in your folder to speed up battles.

* SurprisinglyImprovedSequel: Given how ''Battle Network 4'' turned out, not many were expecting much from the fifth installment. While still a ContestedSequel for the series as a whole, ''Battle Network 5'' is considered to be a massive improvement over its predecessor in story and gameplay, while offering way more innovation to the series than ''4'' ever did.
* ThatOneBoss: [=CloudMan=]'s fights are aggravating due to him hiding in the back row and shielding himself with respawning clouds a'la [=BubbleMan=]'s bubbles. The clouds also spit out sparks that can paralyze if they hit, and when he combines those with the clouds that attack in a + formation it's easy to get trapped and hurt. This is before taking into account the fact he's first fought in a Liberation Mission, which means you have to deal with the 3 turn time limit. He also ramps up the annoying factor with his overworld attack, which paralyzes the target for two turns.

** The Samurai-Whacking minigame in [=NumberMan=]/[=SearchMan=]'s scenario is mandatory for plot progression, and you'll have to knock away 100 robots to complete it. The robots appear quickly and without following a pattern, and if even one of them touches Lan the challenge starts over. This is made especially awkward by the game's isometric view, meaning you're trying to be precise with diagonal movement on a d-pad. It's even worse in the DS version, where this minigame must be played over and over if the player wishes to obtain the ''VideoGame/{{Boktai}}''-themed chips.

** Knight Soul is all-around amazing. Its charged attack hits in an area-of-effect in the eight panels around [=MegaMan=], [=MegaMan=] is invincible for 1 second whenever he uses a chip in the front row, and best of all, you can charge up Break chips for double power. A single charged Air Hockey or Drill Arm chip can shred through bosses and even groups of viruses if used correctly.
** Search Soul returns from ''Red Sun'' and is just as busted as before. Its power is to "shuffle" your currently available battle chips, up to three times a turn. You can do this even while selecting a chip to use and then shuffling the rest to keep that chip on standby. This makes it ''ridiculously'' easy to dig through your folder for whatever you need and set up Program Advances, and adding in Custom+ programs to boost the number of chips you get each turn just makes it easier. The Soul's only downside is that it's fueled by Cursor chips, which are either situational or downright terrible on their own.

** Dr. Regal revealed rather unceremoniously at the end of the previous game that he's the son of the series' main BigBad, Dr. Wily. This connection barely factors into Regal's story in this game until the very end where [[spoiler: Wily shows up and wipes Regal's mind to make him a good guy.]] Regal then ends up ''doubly'' wasted when [[spoiler: the story ends with him now good and joining Yuichiro's research team, which seemingly sets him up as an ally for the next installment. But come ''Battle Network 6'' and he's vanished without a trace and no one mentions him again, not even his own father Wily, who's reasserted himself as the BigBad and whose relationship with Baryl is given the attention instead.]]

* TheyWastedAPerfectlyGoodCharacter: [=GutsMan=], Roll, and Glyde are dismissed from the story within the first hour of the game when Nebula steals the trio's [=PETs=], and Lan's friends spend the rest of the game moping about it unable to do anything (though Mayl at least gives you the Roll series again). This is particularly glaring when you get to the Undernet scenario of ''Team [=ProtoMan=]'' and meet Meddy, a medic Navi whose healing powers can help negate dark power, and her Double Soul is performed with healing chips. Considering the ''Battle Network 4: Red Sun'' had made Roll an opponent and she gave the Double Soul for healing chips, why write her out of the story for this game and then introduce a new character with the same abilities to fill the same role?

While it has better reception than ''Battle Network 4'' -- near-universally agreed to be the weakest entry -- ''Battle Network 5'' still holds onto many of the gameplay changes that occurred going from ''3'' to ''4'', namely the nerfing of Program Advances and gameplay balance focusing on Double Souls and their unique abilities. The story is also better regarded than ''4's'' ExcusePlot TournamentArc, but still not all that great compared to the stories of earlier games.

*** Shadow Chaos has Dark Invis, which turns [=MegaMan=] fully invincible but uncontrollable as he jumps around the battlefield, firing buster shots and using previous chips attacks or even Program Advances at random. In situations where your Busting Rank doesn't matter, you can spam Dark Invis all fight and hope that enough hits connect to finish off the enemy.

* IdiotPlot: The clue that eventually leads to the {{Macguffin}} that Dr. Regal is searching for is found on Dr. Hikari's computer when Lan and [=MegaMan=] check it late in the game. This immediately invites the FridgeLogic that ''no one checked his computer themselves''; neither Nebula, who kidnapped him for information they believe he knows, nor the officials, who are investigating why Nebula would kidnap him. If either group had the thought to just check his personal files earlier in the game, they could have found the {{Macguffin}} within a few hours.
