Ace is a run away irken he used to be a commander genurul until his pack malfunctioned and gave him his emotions back, so he was fired and was assigned to be the tallestess female 'pet', but he didn't want his name to change to Dolly Bell, so he got into a pod and ran away from Irk, to a little unnone planet called earth.
