Eternabeam is a Dragon-type move with an incredible 160 power and 90% accuracy. It is the signature move of Eternatus in its Eternamax form. Eternabeam is a Special attack and, upon use, requires a recharge turn on the next turn, similar to moves like Hyper Beam. This move is exceptionally powerful, making it one of the highest base power moves in the Pokémon games. However, its requirement for Eternatus to recharge afterward means players must use it strategically to avoid leaving their Pokémon vulnerable. Eternabeam is also notable for its visually stunning animation, depicting Eternatus summoning an enormous beam of energy from the sky.
