HM/TM Delete?

[DialgaDiamond]

Hey, I really want to put my Raquazzaa and Kyogore on my Diamond game, but I can't because Rquazzaa knows fly and Kyogore know surf. How do I delete those kinds of moves?
Oh yeah, and are they called HMs or TMs? I forgot, I'm completly clueless today.

With regular moves that a Pokemon learns by levelling up, you can just delete those for new ones. But HM moves like Surf and Fly can't be deleted once a Pokemon has learned them. It's really annoying and I don't know why they made it like that.

They're HM's, and yes you can delete them. On R/S/E go to Lilycove City. A few houses down from the mall is a move deleter.

HM's can be deleted by a move deleter, but you can't delete them yourself. Just go to the move deleter in Lilycove City.

Okay, thanks guys!
I will go there soon!
Thanks again!

In Lilycove city, there is the Move Deleter, he'll delete those moves for you, and they're known as HM's by the way
