All right. Yeesh. I just figured it'd make sense to have her carry a chao doll around with her all the time, perhaps strapped to her back or something. Anything so as to not introduce an actual Chao into the comic. God, I can't stand those things.
Also, you should have a one-off strip where STC Sonic goes to the Smash Bros. Brawl universe. Just for the lulz.
NEW CONTENDER APPROACHES!!!
Cue destruction of the SSBB universe. Work is done and Yahtzee cheers from the sidelines.
....and then we can have moments throughout STC where Sonic didn't know what to do, or how to react, and this guy was there for him, helping him, assisting him. Now the guy wants his due. Can Sonic can on his former master? "Sonic you forget, I helped you get where you are today. You don't stand a chance kid." "You're wrong, unsung hero. Because being a freedom fighter means we NEVER give up!"
Nothing interesting here my friend. Look further down. "Shoot 'em at birth, that's what I say. Yes, I agree. He is great comic maker." Madhair ftw.
