HM04 is a (variable name) (0x41)-type glitch move in Pokémon Red, Blue, and Yellow. It is not capable of causing Super Glitch.
Successfully using this glitch move will result in damage with Hyper Beam's animation. Coincidentally like Hyper Beam, the user also cannot attack until the next turn if the move does not knock out the opponent.
