Knucks and Rebel Rouge saw their home get destroyed and changed by The Eggmen. They were both horrified and formed a resistance group in hopes of getting their home back. Knucks like Knuckles is brave and strong and has determination, but his dim life makes him lack his usual fire. He also has much caution to not get caught in traps and to sense betrayal. Knucks discovered his fire when he thought Sonic and Nine betrayed him. He is a red echidna and an alternate version of Knuckles.
