- Alternative Character Interpretation: Is Shadow Lady:
- Critical Research Failure: About the default colors for some of the Marvel characters:
- Orange and blue Spider-Man. (Likewise, his actual palette is available as an alternate color scheme, but only in original home ports.)
- War Machine having some cyan in his armor, as opposed to fully gray.
- Ear Worm:
- Designated Hero: The game's subtitle is "Clash of Super Heroes", but it includes Venom who is an Anti-Hero.
- Ensemble Dark Horse: Captain Commando, Jin Saotome, and especially Strider Hiryu and Venom. The latter has the distinction of topping character fan polls for MvC3 DLC (alongside Gambit, himself a darkhorse), even long after the dev team stated that his fluid animations weren't compatible with the game's engine, whereas Hiryu (who skipped out on MvC3) had an inordinate amount of fan clamor which singlehandedly forced Capcom to work out a deal with Moto Kikaku in order to get him into Ultimate Marvel vs. Capcom 3.
- Fridge Brilliance: The Marvel secret characters represent other Marvel heroes/villains: Gold War Machine is one to Iron Man (since he has gold armor), Red Venom represents Carnage and Orange Hulk represents The Thing.
- Duo Team Attack (which allowed you to have both our characters on screen at the same time) when used with certain teams plus the Colossus assist.
- Or for that matter the Colossus assist itself. Totally invulnerable, multiple hits, good damage, and gives ample opportunity to do any sort of combo you want it if hits. Psylocke, who has many of these same properties, is also quite popular. And once you learn the trick to get any Assist you want, you'll have no reason to use anything else.
- Any team involving Spider-Man, Strider Hiryu or Wolverine, at least in the right hands.
- Gold War Machine/War Machine together on the same team is this, to the extent where if they do a Duo Team Attack and both perform a War Destroyer, the graphics start to glitch until the moves end.
- Harsher in Hindsight:
- Considering Captain Commando only appeared in this game and the next one, Onslaught's comeback when he is confronted by Cap is darkly prophetic:Your return will be short-lived, Captain.
- Likewise for Jin's ending where he dies and Ryu expresses hope he'll be back, considering he only appeared in two more games after this (and the second game was a cameo in Ultimate Marvel vs. Capcom 3's Days of Future Past stage on a wanted poster).
- Considering Captain Commando only appeared in this game and the next one, Onslaught's comeback when he is confronted by Cap is darkly prophetic:
- Memetic Mutation:
- Narm: Chun-Li's ending, where Charlie saves Chun-Li, but the way he kicks Bison off-screen looks more funny than dramatic. The other endings have varying degrees of Narm too, just watch.
- Porting Disaster: The PS1 port omitted the tag team gameplay due to the system's limitations.
- Rescued from the Scrappy Heap: This game almost singlehandedly did this for its Final Boss Onslaught, who was previously regarded near-unanimously by fans as The Scrappy due to how hard Executive Meddling shoved his titular Crisis Crossover story down the throats of readers back in 1996. Of those fans who remember Onslaught fondly, most were influenced by this game rather than the actual story about him.
- Tear Jerker:
- Hulk's ending, where Cap sacrifices himself to save the world, with the rest of the X-Men eulogizing him. Though this is sad enough, it's the frakking music that makes it worse.
- Jin's ending, where he does the exact same thing is even worse when you realize he only appeared in one more game as a playable character. In Shadow Lady's ending, she and Shadow turn him into a cyborg after he was mortally wounded by Bison.
- Shadow Lady's ending. Although this What If? version of Chun-Li manages to break free of Shadaloo's control and does a HeelFace Turn, she can never become human again as Shadaloo forcibly cyborgized and converted her into a brainwashed minion.
- Tier-Induced Scrappy: Roll. A somewhat strange example considering she was intentionally designed to be a rather poor combatant.
- Unexpected Character: Jin qualifies, as many gamers were unaware of his existence prior to this game. Strider Hiryu and Captain Commando also qualify.
YMMV / Marvel vs. Capcom: Clash of Super Heroes
