This is Maximus (Max for short) — the hypothetical lovechild of Sonic and Tails. Despite her name she is a girl… because Sonic and Tails are weird like that. She's actually been around longer than "Little Shit", but I hadn't actually done any finished work of her.
She's a little tomboy, and specializes in tech to help replant Mobius after the war. In this pic she's about 12 years old, I guess.
But yeah XD forgive us. We just love her too much to keep her a secret.
