I knew Explosion would be an HM for 3 reasons:
~You can't go back to the beggining city without booming some rocks in Moleman Hills
~Dive is in Firered... but has got no uses. Also you know those darkblue tiles in firered? Those were supposed to be diving tiles.
~Professor(insert name here)'s house exploded!
-exactly. Also, a moleman says that he tried with all the usual hms, but it would take a big explosion
- I'll try to give dive some use, at least in a certain place.
-Actually that has nothing to do with that. It was not an explosion, someone just exploded his house. It's part of the story... who burned his house?
Also, it won't be fully an HM, It will be through a move tutor that doesn't stop teaching you the move explosion. (I wanted to modify the HM8, but I have no idea how to)
