In ''[[SM129|Battle Royal 151!]]'', all the members of Team Skull entered the [[Manalo Conference]], although only Guzma managed to get past the preliminary round. While Guzma competed, the Grunts created havoc and mischief around [[Manalo Stadium]]. In [[SM137]], after Guzma had been defeated by Ash in the semifinals, he attempted to dissolve the team, but the Grunts wanted to stay with Guzma, as they wanted him to teach them how to battle as well as he does.
