Who doesn't die if you use hyperbeam?

In the Pokémon games, if a Pokémon uses Hyper Beam, it typically must recharge on the next turn, leaving it vulnerable. However, if a Pokémon is knocked out while using Hyper Beam, it won't faint until the move is fully executed, meaning it can still deal damage before it faints. Additionally, certain abilities or moves, like "Protect," can prevent damage, allowing the user to avoid fainting while using Hyper Beam.
