0010 - Pokemon Blue - Mewtwo
===== [written by JCPMA Sept.21.2011]

This is what Mewtwo looks like on the Nintendo Gameboy Pokemon Blue version game.

Mewtwo is in the Unexplored Dungeon (cave). You can access this only after you have become champion, that is after you defeat the final boss and the game spits out the "credits" and ends. Restart/continue the game. Then travel north of Cerulean City and go into the water. Travel south for a short distance until you see the entrance of the the cave. Mewtwo is in this cave.

Unfortunately, I no longer own a Master-Ball. Several attempts at using Ultra-Balls failed to capture Mewtwo. But, I was able to defeat him in a fight.
