Sonic the Hedgehog

Sonic the Hedgehog is the titular protagonist of the Sonic the Hedgehog franchise and mascot of SEGA.

History
When Sonic was little,he was raised by his surrogate mother, Longclaw the owl. She took good care of him. But one day, Sonic was using his powers of super speed (which were meant to be secret). Then suddenly, they are ambushed by a tribe of echidna archers. Longclaw desperately flies away with Sonic, only for one of the echidnas to fire his arrow and successfully strike her, causing her to plummet to the ground with Sonic still clinging to her. Though injured, Longclaw reminds Sonic of the importance of keeping himself and his powers hidden, and uses a golden ring to open a portal to a world on the far side of the universe, called Earth.

How Sonic the Hedgehog should have ended
Sonic is standing up to Doctor Robotnik but then, Tails, Amy, Knuckles, Shadow the Hedgehog, and more come to help him. Robotnik says if they are having an Avengers portal knockoff scene then he is having one too and summons the Badnik Carreys. After a long battle, Sonic and friends defeat the Badnik Carreys and Robotnik.

In another alternate ending, Tom comes in with a gun, Sonic is there holding a ring trying to convince Tom he was a cat. Tom shoots him and Sonic freezes time. Sonic wonders if him and Tom should be friends, or even he should have just let the bullet hit him, but recalling Longclaw's advice to run away from his problems, he leaves. Sonic finds a mushroom planet and meets Mario. Sonic is displeased to see him.
