Suggested by Sonic Deathbird is an agile fighter with a whole lot of super strength and speed at her disposal. While Mecha Knuckles is a power type as well, I’m not sure that he will be quite up to the challenge this time. She can out speed his missiles and I think she can handle his power with her own. Ultimately she’s more agile and speed will be the winning factor here. Mecha Knuckles wins.
