Lucario is my bitch. He's on all my teams.
I saw him first as "Rukario" on serebii and I'm like "OMFFFGZ A FITE STEL TYPE POGEYMAAAN" and I was in love immediately. Seriously, 4x Rock Resist, 4x Dark Resist, 4x Bug Resist, Dragon Resist, Normal Resist, Toxic Immune, and so much more great aspects. The weaknesses let him down...Fighting, Fire, and Ground are all very common attack types. But I don't care. I will always use this beast.
