he's in western cave
Mewtwo is on the 99th floor of western cave
Recruit Ho-oh from Mt. Faraway. Then, an event will trigger, opening Western Cave.
Keys can be found on the floor in Solar Cave and Western Cave. They are more frequently found in Solar Cave, though.
mew=buried relic mewtwo=western cave
99 and at the end is mewtwo
it's the same as the pokemon mystery dungeon red rescue team. you can find mewtwo in the western cave once you recruited ho-oh.
You get it when you recruit Ho-oh though I am not sure if you have to recruit it or just beat it
