Nah, the type should split depending on the evolutionary path you take. Like Snorunt, and Poliwhirl and everything else in the series.
snorunt is kinda not the best example. it works for both sides of the argument with one evo keeping the type of the the prevos and one getting a type change.
Glalie for Ice/Fairy? <.<
Glalie should have been Ice/Dark just by it's desigh, i mean just look at it, it embodies a face of a dark type XD.
I have always thought this.
On topic, pretty much what everyone else said. They should stay pure Psychic because then Gallade would make no sense. Being male only and evolving differently should have nothing to do with the type of its prevolutions.
and in theory it gaining a type (and possibly now changing a type) doesnt have to be effected by its prevos.
am i the only person that wishes game faqs offered the option to cut peoples comments from your topics?
