Water/Fighting Mantis Shrimp
Compound Eyes or No Guard for its incredible eyes and aggressive nature. Maybe iron fist too
Learns punching moves like mach punch or dynamic punch, but can learn aura sphere or focus blast due to its punches being so fast, it can create shock waves strong enough to create high temperatures and light.
Maybe its prevo can be a wimpy shrimp that evolves either into a smasher-claw water/fighting or a spearer-claw water/metal
