Their both bat Pokemon. One is based on a Vampire bat and the other is based on the Heart-nosed Bat and a species of fruit bat.
Anyway lets get back on Topic. I didn't bother naming my Musharna. Its just not a Pokemon I could train, I hate the way it looks. I may change my mind in time but I doubt it, its one of the few Pokemon that hasn't grown on me.
