I'm going to have an emboar with fire punch, thunder punch, iron head, and brick break. Should it have adamant or jolly?
Adamant. His speed is terrible and is outsped by most Pokemon already, so why not invest in attack?
I'd go Adamant, not sure if speed is the best investment on Emboar
Go jolly ONLY if he was RECKLESS & you gonna CHOICE SCARF him & EV train him in speed , and give him this set of moves FLARE BLITZ + HEAD SMASH + SUPER POWER + WILD CHARGE , that will benefit from his ability.
otherwise go adamant !
