Encountering in battle.

is a dual-type 999/Normal Glitch Pokémon that is found in Pokémon Yellow. It can only be obtained via the Time Capsule exploit with Chikorita. It occupies hexadecimal slot BF.

If encountered with the Mew glitch, with a stat of 191, the game will freeze and no action can be taken, which then leads to a crash.

The reason why it crash the game, is due to it setting to a invalid sound bank, which is due to that 4 4's (invalid) front sprite is unusually huge (256x256), which causes it to overflow from RAM to SRAM which then corrupt the current sound bank identifier address into invalid sound banks. Since invalid sound banks (usually) crashes, 4 4 will (usually) crash due to that. It could actually be encountered without crashing, which is by using the gameshark to prevent sound banks from ever changing (0108EFC0, 0108F0C0), and 4 4 could be encountered without crashing (since sound banks didn't change to invalid). But even doing that, the battle couldn't be continued forward due to the fact 4 4's sprite overflowing also corrupts address that RAM holds (http://datacrystal.romhacking.net/wiki/Pokémon_Red/Blue:RAM_map). Since 256x256 is a ultimately huge size, it could possibly corrupt the whole RAM, turning the whole game into gibberish.

Example of using gameshark to encounter 4 4 here: https://youtu.be/wiqosSUVVf8

's cry in battle is part of the sound of the move Surf; however in its summary it has the cry of a Rhydon, and when withdrawn or deposited at a PC its cry is a slowed-down version of the melody of Cinnabar Island. 's solid glitch screen makes using it in battle difficult, as the player won't be able to see the battle menu.
