Just looking for advice. What nature should i use with my aron? I was thinking brave for some more attack, and well aron isn't about to win a speed contest anyway. (I'm to lame to play competitively so please refrain from directing me to the battle forms)Maybe sassy for some more sp.def I'll admit it I don't really know how to match pokemon personalities.

Adamant is your best choice for a Physical attacker. It won't be using Sp. Attacks anyways with that abysmal Sp. Attack stat.

good point, I think I'll go with careful or adamant as you suggested, whichever pops up first. Thank you for the help

Adamant, Careful, Brave, or Relaxed all work if you don't care about speed or special attack.
