Okay. This isn't going as planned and the Monarch has no henchmen to order to fight this guy.

That being said, he didn't get to the level of villainy he is at by being a quitter. Maybe if he can get this guy monologuing, he can figure something out. Distract the source to kill the light, as it well. The Monarch holds his hands up in a defensive position, backing up to the edge of the roof, being mindful not to get too close. Just enough to see Starscream himself.

"What, like it's something new? Please."
