>>58421369Burmy gets different forms because there's a couple moth larvae do what it does (builds a outer casing of bits of crap it finds lying around its habitat) and of the two, one specifically displays extreme sexual dimorphism, with males metamorphosing into moths and females staying in their more immature forms. Venusaur displays dimorphism between males and females, like Pyroar does (to a lesser extent, true) and doesn't bother distinguishing gender under ME. There's no reason for Pyroar to do so.
