Gokudera would never. The blasts from his cannon and bombs would either knock Peter out, kill him, or just leave him covered in some very cartoon scorch marks. It just depends on how the muns want this to play out on how things go in the heat of the fight. Despite his bad attitude, and how he doesn't like other people, a good majority of their spectators are aliens and Gokudera adores them. He'll keep them safe, and he isn't going to damage much around them. Property damage is his forte, but this is a space cruise ship and he's not sure he even has currency enough to cover his own food or drinks let alone scorched and damaged ship interior.

"Alright alright! Just hit me already!" He says, sounding aggravated, but it is nice to see someone excited about his weapons. The entire system isn't even out, and it's his pride and joy.

Honestly, the closer Peter gets, the safer he will be. Gokudera's got his bone loops out, but is not using them on himself, so... there goes his attempt to bludgeon the other boy. Gokudera flicks his hand to one box, pulls out a metal canister, and puts it right into the strange cannon strapped to his arm. The skull above Gokudera's fist opens its mouth and shoots out a beam of light, like a laser, but with red fire and a current of green electricity curling around it. It's pointed at Peter, and would be easy to dodge, but it's also got a nice shield to bounce of, and will pinball about until it hits either of them, or the floor. Gokudera could probably glide about on the last disc he hasn't called out, but he'll stay on his feet, stepping back to try and keep distance between them.
