L_G can't be stunned as long as he has Nogauntlet equipped. Forgot about that, didn't you?

L_G fires two Firaga bullets!
Tangent takes 1789 HP damage.
Tangent takes 1804 HP damage.
Bulla is still asleep.
Trunks is stunned and can't move!

I assume that since Tangent is now a creature of the underworld (in a sense), he is vulnerable to fire. I think. ^^;;
