Why does Detect have less PP than Protect?

Question

They are completely the same moves!

And try to make it more than a "GameFreak made it that way" answer if you can.

Answer 1

Well, it's one of those questions that have no good answer beside, "Because Gamefreak wanted it that way"; so it's just Gamefreak's weird logic.

Answer 2

Actually, there are several reasons. A Pokémon with Detect and Protean will become a fighting type, more useful than being a Normal type. But the kicker is that in Doubles, the move Imprison will keep you from using Protect, but Detect is still usable. Hope I helped :)
