'''X-Men: Children of the Atom''' is the beginning mark for the VideoGame/MarvelVsCapcom series.

Sometime around 1994, {{Capcom}} gained the rights to make video games based on the heroes of MarvelComics, starting with VideoGame/XMenMutantApocalypse for the SuperNintendo. This being the early 90's, with ''StreetFighter'' mania in full swing, they decided to start with a FightingGame using the Comicbook/{{X-Men}}.

The game had six of the X-Men (Cyclops, {{Wolverine}}, Psylocke, Iceman, Colossus, and {{Storm}}) and four of their enemies (Silver Samurai, Omega Red, Spiral, and a Sentinel) taking each other on in a series of one-on-one battles, before fighting their way through the Juggernaut and facing Magneto in a final showdown. Akuma, from ''Super VideoGame/StreetFighterII Turbo'', makes an appearance as a GuestFighter SecretCharacter, thus paving the way for the eventual coming of CapcomVsWhatever.

The game featured a unique exaggerated and animesque style accompanied by massive screen-blasting [[LimitBreak Super Combos]] and the ultra-high jumps needed to avoid them.

Naturally, the game was a hit, and it was followed in 1995 with '''VideoGame/MarvelSuperHeroes'''.

* ShockAndAwe: Storm's primary form of offense, as well as several of Silver Samurai's attacks.
* {{Shotoclone}}: Cyclops.
* ShoutOut: Check [[ShoutOut/CapcomVsWhatever the page]].
* SNKBoss: '''Magneto'''. His AI is complete bullshit and seeks to royally piss you off at the worst time possible. He can fly away well out of your characters' reach and assault them with an extremely fast, damaging projectile. He has another move where he sends in four magnetic balls that are ''unblockable'' and home in on you, and when he catches them he can do whatever he wants. His super hits off-the-ground and unlike in other games reaches the top of the screen vertically, plus does ridiculous damage and it's very hard to avoid it. He's really fast, does a ton of damage with just a few blows, he is really difficult to get inside of and just has everything.\\
\\
To make things even '''''MORE''''' insulting, his throw allows him to follow-up with pretty much anything since it freezes you. Plus, his super meter fills automatically and he has a full bar in seconds to spend on flight, Magnetic Shockwave or a ''force field where he is COMPLETELY INVULNERABLE'' to attacks for a set period of time.
** PuzzleBoss: Then again, if you study him long enough, you will notice that he always follow a strict pattern which you can exploit.
* {{Stripperiffic}}: In the ladies' side, we have Psylocke. And in the men's side, if one is feeling crazy, Colossus.
* SurprisinglyGoodEnglish: All the characters save Silver Samurai are voiced by native English speakers.
** In fact, most of them have their [[WesternAnimation/{{X-Men}} Animated Series]] voice actors.
* WhenAllYouHaveIsAHammer: All of Cyclops' moves (in this game and the later ones he appears in) are basically various forms of optic blasts.
** Not entirely true: Cyclops had two special attacks that didn't use his optic blasts- Cyclone Kick, a spin kick attack that was fairly similar to Ryu's Hurricane Kick, and Charging Tackle, a running grapple that ended with an elbow drop.
* WolverineClaws: Wolverine, duh.
* ZerothLawRebellion: In Sentinel's ending in ''X-Men: Children of the Atom'', [[spoiler:after defeating Magneto, Sentinel returns to earth. Then, the complete Sentinel line is activated and they start to wipe all the mutants on earth. After the success of the mission... they [[KillEmAll start wiping out humanity]]!]]
