Dead End's definitely not used to people actually liking his paint job. It's usually insults or just calling it weird or overly bright. Basically insults and more insults.

"Glow?" He blinks, staring down at the human. Aside from his optics, mouth and swords, no. No he doesn't glow.

He shakes his head, "I don't glow. Wouldn't work out for me."

If his whole paint job could glow... Well he'd end up dead when he sneaks around to kill people.
