Psychic types may be weak to ghosts, but this Mew here is well-equipped to handle Gengars and their motorcycle antics.
I made a regular version and a shiny version. He will desync wifi because I had to disable his arm bones. All of his attacks still seem to work fine, with the exception being when he has the beam sword item. He gets almost no range with that.
CSPs and Battle Portraits included. Big thanks to Beyond for his tutorial on removing normals.
