In Sonic the hedgehog 2, Sonic can become "Super" by collecting 7 chaos emeralds while holding 50 rings and pushing "Jump" twice. He becomes an invincible golden hedgehog that can run super fast and jump incredible hights, not to mention he can run accross water at will. And as he was created before dragonball z, i doubt sega ripped them off, more likely it was the other way around.
Yeah, i got the seven chaos emeralds by the fourth level, and owned Dr.Robotnik (Who's name was changed to eggman because robotnik sounded to russion or somthing) through the rest of the game using Super Sonic.
Also known as s^3, they are a vex robotics team, who every year somehow manges to field excellent robots. The team is the textbook example of winning award regardless of robot performance. I swear they can win excellence and be the worst seeded robot
