Starfire can survive in space. That doesn't mean being inside this thing is... pleasant, or isn't scaring the hell out of her.

Inside the dark, fleshy tomb of the inside of the zombie's mouth... stomach? Whatever it is, Starfire goes for a whole-body starbolt explosion.

She lets it build up in her for quite a bit before letting it finally go off, making it one of her stronger bursts, hoping it will burn and/or break through the thing trapping her inside it.
