Kabutops

Kabutops has an excellent offensive STAB combination, allowing it to hit most of the tier for neutral damage. It is also one of the only two relevant Aqua Jet users in the tier, which allows it to revenge kill fast Pokemon such as Archeops and Pyroar, which may otherwise threaten Kabutops with their coverage moves. While Kabutops's typing is really good offensively, it's below average defensively, leaving Kabutops weak to common types such as Grass, Ground, and Fighting. It also isn't that bulky, which makes it somewhat difficult to set up or spin and limits the usefulness of its resistances to Normal and Flying.
