Do the enethe that appear in arcade game when running out of time have a canonical name

I never seen confirmation that any of those rumors about codes were true. There is a setting called "Free Play" on most arcades that the owner can enable, however, which involves opening the case itself. This may have been what started the rumors.

EDIT: That's not to say that some games didn't have a glitch that allowed free play to become available without opening the cabinet. This sometimes involved actions like physically turning the machine off, then rebooting it again when it was at a certain point in the startup sequence.

Each mutant has similar basic punches, throws, and attacks, but each has a unique mutant power to destroy their foes. Cyclops uses an optic blast, Storm calls a tornado to kills enemies, Nightcrawler teleports and destroys enemies on screen, etc... Mutant powers are the only things that truly distinguish one X-Man from the next, as all other attacks are the same for each character.
