I have 3 Lucario, all of them are level 100, but they have different natures and slightly different movesets (before anyone flags: Should I ask this at the Battle Subway?):
Lucario #1 (Gaia)@ Black Belt
Lucario #2 (Anubis) @Lucarionite
Are there any other details I should add? I don't know how to calculate EVs/IVs...
The one I use the most is Lucario #1, but I don't really relish the fact that he has a Mild Nature. My least favorite to use is Lucario #2 because I know I can improve its moveset (unless you think it's fine for an in-game set, at least.) Lucario #3 seems all right to me but I barely use it. I know all of their movesets have some similarities, so perhaps this is just a "battle of the natures"? Thanks in advance!!
