Kingler

While Kingler boasts an impressive Attack stat complemented by a decent movepool, Sheer Force, and Agility, which gives it a decent matchup against offensive teams, it sadly struggles to break through walls like Vaporeon and Seismitoad. Moreover, its bad special bulk makes it extremely hard for it to set up and leaves it easily revenge killed by faster threats such as Sceptile and Magmortar and by priority move users like Comfey after setup. It also suffers from competition from other Water-types wallbreakers such Samurott, which has higher bulk, Aqua Jet, and Megahorn and can afford to use a Z-Move, giving it a stronger Bug-type move in Savage Spin-Out.
