Sonic The Hedgehog (SRC)

"We'll try to find our way back to Mobius, but until then, just try to enjoy yourself here."
 * Sonic talking to Tails about getting home in Chapter 26

Sonic The Hedgehog is a renowned hero on Mobius, known for his exploits in defeating Dr. Eggman several times on several occasions. He is the hero of the eponymous Sonic the Hedgehog video game titles, made by SEGA and its affilated companies (such as BioWare for the development of Sonic Chronicles: The Dark Brotherhood.)

Appearance
In Sonic's Reality Check, Sonic appears (in all of his appearances to date) with short and flattened out blue hair and his signature red shoes with a white strap and yellow belt buckle. However, there has been (currently) one costume change made to Sonic. This is his appearance, as follows.

Chapter 1 to the Beginning of Chapter 24

 * A dark blue shirt
 * Tan jeans
 * No gloves

The Rest of Chapter 24 Onward

 * A white t-shirt with orange rings at the ends of the sleeves, the neck hole, and the bottom of the shirt
 * Metal belt
 * Cameo pants
 * A pair of black wristbands that have two stripes of blue going parallel to each other on the fabric of the wristbands

Personality
Sonic is a good-hearted hero and a nice guy, and although he lacks a short temper, when provoked he can be deadly. He has an overwhelming sense of justice, which is shown when he defies the odds to save his friends and even sometimes his enemies.

In SRC, Sonic retains these base qualities, and not much of his personality has drastically changed. However, it can be seen that he is more lax than usual, and that he tends to not like hanging around Amy as much as he normally does, although this is rectified by somewhere around Chapter 20.

Sonic's Role
Sonic has had little roles in SRC, at least up until Chapter 20. Sonic, for the most part, had been the butt of many Sonamy jokes throughout the series up until Chapter 20. In Chapter 20, Sonic learns of Amy being kidnapped, and he does his best to save her (after some persuasion by Shadow and Silver. Sonic then begins becoming more of a "brotherly" character to Tails whenever Tails learns of Cosmo's possible destruction by the hands of either Nega-Nick or another force. Sonic has matured greatly since his inital appearance in Earth at this point in time, and he follows whichever lead he can get to obtain another Chaos Emerald for their quest to find their way home.

Sonic (surprisingly) still has less screentime than some of the other canon character however.
