The Pokemon meta has undergone substantial changes over the years as each generation introduces new mechanics and critters that build upon those that came before them. Additionally, games like Pokemon Legends: Arceus have introduced new forms of previously existing mons, remixing critters from older generations to fit within the most recent one. However, even after gaining a Hisuian form in Pokemon Legends: Arceus, Arcanine remains one of the best Gen 1 Pokemon in the modern Gen 9 era for competitive battles due to its consistently useful ability and great support potential.
