Hyper Beam is a Steel-typemove introduced in Generation I. Most evolved Pokémon are capable of learning this powerful move. However, while it is extremely powerful, its only downside is that the user is forced to recharge next turn.
Many competitive players shun the use of Hyper Beam because most moves can do more damage over 2 turns than Hyper Beam does, as well as the fact that it is a Normal type attack, and therefore cannot be super-effective. Since Generation IV, Hyper Beam has been reclassified as a Special Move so Pokémon with high Sp. Atk. could make good use of it. Its Physical counterpart is Giga Impact.
