Mega-Gallade is a must pokemon on fighting due to its great typing, great setup capibilities, and a amazing attack, making it a great wallbreaker. Its dual stab allows it to pressure poison types such as Mega Venasaur, Toxapex, and Galarian-Weezing all of these are pokemon that fighting usually strugles with due to being able to spread depricating status, and there great bulk. While Urshifu is usually petter at this role, M-Gallade can pressure psychic types with knock-off.
