ゥ is a Poké BB-type glitch Pokémon found in Red and Blue. It occupies hexadecimal slot F4. It evolves into MissingNo. at level 195. This glitch Pokémon can be obtained via the Time Capsule exploit with Forretress. If attempted to catch via the Ditto glitch, the player will encounter Lorelei instead. ゥ's cry is that of Raticate's.
ゥ has a glitch screen; the red-tint variant in particular.
It should be noted that ゥ knows a Super Glitch move as one of its starting moves, and care must be taken that the move's name not be viewed in any way, unless in controlled circumstances.
