Eternamax (ムゲンダイマックス, Mugendaimax, lit. Mugendaimakkusu) is a feature appearing in Pokémon Sword and Shield. It is a variant of Dynamax and Gigantamax; while any Pokémon can Dynamax and Gigantamax, Eternamax is only exclusive to Eternatus. Like Gigantamax, in addition to changing the Pokémon's size, it changes its appearance as well, thus works similarly to Mega Evolution. This feature, however, is unaccessible. You can temporarily use it while using Eternabeam, however.
