Floored! said:Here is a list of Pokes who use earthquake and "never touch the ground": Gyrados Aerodactyl Mew* Forretress Steelix Mantine Ho-oh* Wailmer Wailord Glalie Metang Latias Latios Rayquaza
* = Questionable
Just because something flies doesn't mean it never touches the ground. So, Aerodactyl, Mew, Mantine, Ho-Oh, Lati@s and Rayquaza are easily explained there. Rayquaza may apparently live in the ozone layer but if it needs to touch the ground, I'm more than certain it can land.
As for the water types, there are such things as underwater earthquakes. Besides, what if there's a battle in a completely landlocked area?
How the hell do Forretress and Steelix never touch the ground?
So, we're left with Glalie and Metang. They may both be shown to levitate but much like Rayquaza, they can land if they want/need to...
