Did you see Thin Buu(Evil Buu) vs. Mr. Buu(Fat Buu)? Thin Buu directed back the beam. Gill could probably do the same with seraphic wing(yes it's seraphic Wing again). And about distraction, though Gill is a powerhouse, he isn't stupid enough to get distracted and then get hit, he always keeps an eye on his opponents.

I'm sure that you know that the some of Saiyan/Saiyajin fighters could distract Gill for a while. Besides, if Vegetto came and KOed Gill, he would be too busy trying to heal himself, leaving him open to the Henka Beam.
