Hyper Beam causes damage. Your Pokémon must recharge during the
following turn, and can't take any other action.
If the attack misses, breaks a Substitute, or faints the victim, your
Pokémon does not need to recharge.
Because it is a Normal type attack, it cannot affect Ghost Pokémon.
* - This number is slightly low for RBY, as the process sometimes
only takes one turn, for the reasons mentioned above. This is unlike other
two-turn attacks, such as Sky Attack,
which always require both turns.
