Suggested by iKnowledge Natsuo is an excellent fighter and top of her class in the MMA world but Mockingbird will still win this one. Even if Natsuo may have slightly better speed and technique in base forms, Mockingbird received the serum at one point which boosted her strength to Captain America levels. She was able to shred robots like it was easy and endure building wide explosions. Natsuo can’t hold her own against such a super fighter at this point. Mockingbird wins.
