Marvel vs. Capcom 2: New Age of Heroes (2000) is arguably the most popular game (as of yet) in the Capcom Vs. series.The final 2D entry in the Marvel Vs Capcom series, it sandwiches every playable character from X Men Children Of The Atom all the way up to the original Marvel vs. Capcom. The only absences are the Vs Boss characters, the palette swaps, and most helpers from the previous game.To make things easy for you, that is a whopping 56 individual characters, placing the game among those with the most numerous cast.If that wasn't enough, the game bumped the teams up to three fighters per team, allowing you to select different sets of assist attacks and Double (and Triple, of course) Supers. The game also allowed you to chain supers together for absurdly long and painful combos, or just safe, if costly, switching between characters.Eventually, Capcom lost the Marvel license, and both companies would follow separate routes until 2008. After massive fan demand (and the success of SuperStreet Fighter IITurbo HD Remix), MvC2 was rereleased for Xbox LIVE Arcade and the PlayStation Network with online play. This reignited the Marvel and Capcom relationship, and in 2010, the companies announced that the game would get a true sequel in the form of Marvel Vs Capcom 3.
Composite Character: Zangief and Sakura may qualify, since they have the ability to transform into Mecha Zangief and Dark Sakura during battle, who were technically separate characters in Marvel Super Heroes vs. Street Fighter.
Cool Ship/Cool Airship: Ruby Heart, being a trans-dimensional, world-traveling pirate, is in possession of one. It also is the cast's main form of transportation, one of the fighting stages of the game AND one of her Super Combos.
Damn You, Muscle Memory: Two assist buttons are added, but both medium attack buttons have been dropped. Some medium attacks have been retained as launching command attacks, while others can only be done by pressing a weak attack button twice within close range.
Divergent Character Evolution: War Machine in MvC was exactly like Iron Man in the earlier games. In MvC 2, he gets Gold War Machine's special moves, replacing Iron Man's beam attacks with guns and missiles (which is closer to how he's portrayed in the comics).
Game Mod: Before the Xbox LIVE Arcade version was announced, people were making custom Dreamcast ISOs with custom soundtracks, (due to its heavy Soundtrack Dissonance) and custom colours. There wouldn't be "Mango Sentinel", "Sicily in the middle of Italy" nor "Bitch be blue like candy" without this, for Yipes' sake!
Loads and Loads of Characters: The game included pretty much every playable Marvel and Capcom character inside of Capcom's Marvel games that was featured in the series up to that point, to a grand total of 56 (counting both of Wolvie's forms, and not counting the boss).
Long Range Fighter: Several, but the best example is Blackheart. Even his punches and kicks summon projectiles.
Just to clarify, Abyss' first form isn't hard to take down melee, but the second form pretty much requires liberal projectile usage. The third can be taken down in either fashion, but leans towards aerial attacks.
Soundtrack Dissonance: The infamous original soundtrack, consisting of jazzy music. The entry on that page likens the dissonance to using zydeco music in Silent Hill.
Updated Rerelease: If you are really (and we mean really) technical, the 2009 port could count as this with its additions of online play, fixed glitches, custom soundtracks and sprite filters. No more, no less.
Victory Fakeout: Happens twice with Abyss. Each time you defeat its first two forms, the usual YOU WIN! message appears, and your onscreen character even does his victory pose. Sadly, your health is not restored.
Voluntary Shapeshifter: Amingo and Venom make extensive use of this in their movelist. Then there's Shuma-Gorath (who can change shapes into mouths, spikes or even stone), Spiral (has one Super in which she turns into everyone on Marvel's side of the cast), Morrigan (can shape her batwings into several forms), Felicia (can turn into a small kitten) and Anakaris (can shape into various pyramid-shaped forms)
Wave Motion Gun: Iron Man's PROTON CANNON, Cable's HYPER VIPER BEAM and Morrigan's SOUL ERASER
A Winner Is You: Unlike the first game, there's no separate endings for the characters. You get a little uncolored slideshow of the characters mingling on Ruby's ship after the Abyss battle and that's pretty much it.
