It's Piglit, Pignite, and Pignition, but since we only know one Pokemon in the line right now, he's just dubbed Pignition.
Also, I take no credit for the names, they come from /a/ and /v/.
Wait, wait wait - They aren't confirmed names right? They sound like it, but I haven't heard them anywhere. I'm guessing /a/ and /v/ is a person?
