Pick the story you would like for me to continue:

History of Heavenly Damnation
History of Hasidic Samuri
Sonic's Final Battle: Yolkum, Eggman's biggest fan.

In the third choice, Yolkum is a boy who looked up to eggman, but when he gets too old to fight and destroy sonic, and decides to retire from his villainy, Yolkum decides to take his place. He announces his bid for world domination as Dr. Evan "Yolkum" Masheenik, and forces Eggman and sonic to team up for a final fight. Yolkum has built improved versions of Eggman's most powerful machines, including the Flying Serpent (Egg Viper) and Beta MK III (Beta from Sonic Adventure 1).

"Dr. Evan "Yolkum" Masheenik" is based on "Dr. Ivo "Eggman" Robotnik."
