Incineroar

The combination of Knock Off, good typing, and Intimidate makes Incineroar a great wallbreaker while being a solid defensive Pokemon. Sword Dance sets can make Incineroar into a great wallbreaker, since many defensive staples like Amoonguss, Galarian Slowbro, and Registeel just drop to its Swords Dance-boosted STAB attacks. Also, Incineroar easily checks the common Ghost-, Grass-, and Steel-types like Chandelure, Decidueye, and Klefki, meaning it can take advantage of its utility moves with a defensive pivot set if it wishes. It has Will-O-Wisp and Knock Off to cripple incoming physical wallbreakers like Toxicroak, Flygon, and Paldean Tauros-W and item-reliant Pokemon like Diancie, Avalugg, and Swampert. Defensive Incineroar is also solid for handling special wallbreakers such as Chandelure, Porygon-Z, and Heavy-Duty Boots Munkidori. However, Incineroar's low Speed stat makes it very easy for wallbreakers with a middling Speed tier like Basculegion, Breloom, and Heracross to outspeed and destroy it with their own STAB attacks. Incineroar's reliance on Heavy-Duty Boots can be felt, since it has to be wary of switching into opposing Knock Off from Tsareena, Alolan Muk, and Wo-Chien. It even has to worry about switching into the Pokemon it checks best, Chandelure, as it carries Trick to cripple Incineroar. Incineroar also lacks any form of recovery, making it easily worn down over the course of a battle.
