A term that’s used a lot in programming with some ire is “singleton” - a feature or concept that’s only used once in the entirety of your software. They’re a huge pain in the ass to implement and are usually a “last resort” kind of situation. I’ve been thinking about them a lot in Marvel because this game has more singletons than any fighting game I can think of. I wanted to try to list some and see how many the community can come up with. Some are obvious, some not so much.
THE RULES: These are system mechanics or states that only happen as a result of one specific thing. Some examples:
HAGGAR: Haggar’s 8H (headbutt) in the air when it counter-hits causes a knockdown state where the opponent’s character looks normal but can be OTGd by any ground move. No other move in the game causes this knockdown state.
ARTHUR: Arthurs 5M on the ground has a number of auto-guard frames that will block mid attacks. Not super armor or invincibility - the attack is treated as blocked, not absorbed or whiffed. No other move in the game has auto-guard frames.
V. JOE: Shocking Pink is the only projectile in the game that can damage both allies and opponents.
FRANK WEST: Frank’s snapshot is the only move in the game that reads data from the combo counter.
PHOENIX: Phoenix is the only character in the game that can come back to life after losing all her health (with 5 meters stocked).
MODOK: Modok is the only character who gains abilities by connecting with a specific move (Analyze Cube) and has a “stock” of those abilities that can be depleted.
NOVA: Nova is the only character in the game who loses red life from performing specific moves.
What other ones can you think of?
