Shuma Gorath is a Marvel Comics character and one of Dr. Strange's foes. He is a extradimensional warlord and lovecraftian horror who wants to conquer our dimension and add it to the incountable amount of dimensions under his control. He was made into a fighting character in Capcom's Marvel Super Heroes, later appearing in Marvel Super Heroes Vs Street Fighter, Marvel Vs Capcom 2 and Marvel Vs Capcom 3.
Qkrtkf's version is based off his Marvel Super Heroes appearance, with the purple palette as the default and a gem system implemented.
Sludge's version is based off his MvSF and MvC2 appearances, though his Mystic Stare was changed into a regular projectile. It was made for the Super Marvel vs. Capcom: Eternity of Heroes project.
ゴマ's version is a improvement of Sludge's version, with the Mystic Stare fixed, many bugs of the original corrected and an agressive AI added. It comes with two separated def's: one for his MSH voice, and one for his MvC3 voice.
Basara-kun's version is a version of Shuma-Gorath with custom gameplay, with features from all of his various appearances. It is currently in beta state, with some moves still not implemented.
Cyanide's version is based off his MvSF appearance. It is mostly source accurate, though it adds the Hyper Mystic Ray (complete with new custom sprites) as a bonus.
