He's not an alien nor does he have super advanced tech. He's a cop with a flaming skull for a head.
And of all he has, he just ever uses the gun more than once. The show he's from is a little... well, you should go to youtube and watch Inferno cop. the episodes are three minutes long, and fairly self-explanatory.
Anyway, I'd keep up the trend of anything except the gun being forgotten after one use, if Elf doesn't think Inferno Cop is too retarded.
