Because the Sub-Forum desciprion demands it!
Rattata. One of the first Pokemon known to players. Based on a rat(duh!), it is Gen I, early route normal type pokemon.
Bidoof. Gen IV's early normal type. Except its much more than that. It appears everywhere in Sinnoh. That and its appearance has led to many jokes and hate. Upon evolution it turns into an awesome HM slave.
Who do you like more?
Who has the better design?
Who would win in a battle?
I like Bidoof more. It has the better design and I think it would win in a battle.
