Sonic the Hedgehog

Sonic the Hedgehog, or Sonic, is a blue anthropomorphic hedgehog gifted with super speed from birth, hailing from Mobius, an alternate dimension from the Mushroom Kingdom, native to it's capital South Island. He is the main protagonist of SEGA's long-successful Sonic the Hedgehog franchise. Sonic has appeared in some of SuperMarioGlitchy4's Mario videos, and is the main protagonist in the Sonic the Derphog sub-series.

The Wacky Wario Bros.: The Winning Ticket.
He made an appearance telling the viewers that he is Sonic, Sonic the Hedgehog, but then was ran over by Wario's car. He then appears where the (Wacky) Wario Bros wait for the bus, along with Kirby. He then sees Wario and notices that he was the one that ran over him. He then battles Wario, he uses Chaos Control to slow down Wario, Wario then throws Waluigi and Kirby into Sonic, but misses, but then got ran over by a train, ultimately killing him, he wasn't seen for the rest of the video.

Super Mario 64 Bloopers: Who let the Chomp out?
Sonic made a small cameo appearance. He greets the Chain Chomp at the door to the castle and introduces himself. He then later becomes friends with Chain Chomp.

DerpTV: Super Happy Fun Fun Gameshow
Sonic made a small cameo appearance again. He was in the backstage and encounters Mario, who throws him to the Chain Chomp, who later rewards Mario a free holiday to Teletubby Land, much to the fury of a plumber, who throws tantrums.

Trivia

 * Sonic is the second SEGA character to be featured in SMG4's bloopers, the first being Dr. Robotnik/Eggman (who appeared more often than Sonic).
 * Sonic acts calm most of the time, is intelligent, and uses common sense, unlike Mario, who occasionally acts like an idiot, has anger issues, and uses violence to solve his problems. This makes sense seeing as Mario and Sonic were rivals in the real-life "console wars".
 * Sonic is friends with Chain Chomp on Facebook. It is also revealed that their friend request was mutual. (If you don't know what that is, it is when both people send a friend request to each other simultaneously.)
 * Sonic may be bisexual, as he was attracted to Amy in Sonic The Derphog: The Evilness of Eggman (?), but later told her that he was gay (this was probably an excuse for her not to attack him).
 * Sonic's relationship with Eggman parallels their depiction in the Sonic Boom series, showing as while they're professionally enemies, they typically act like friends.
