Peter can deal with some cartoony scorch marks, he would like to keep all of his limbs though. His spider-sense is probably enough to help him avoid death and dismemberment, at least. Whiiich good thing he has that, because now there's a friggen laser beam bouncing around all over the place. The initial dodge is easy enough, he hops straight up and over it, but it nearly hits him on the rebound when it starts bouncing off of shields. In fact, most of the next few moments is spent hopping around dodging that laser.

It does hit the ground eventually, and as soon as Peter is no longer dodging lasers he's quickly trying to close the distance between himself and Gokudera. He just has to get in close enough to pop this guy like once, and this fight'll probably be over. He could probably use his webs to help, but naaaah, he'll hold off on flinging sticky web goop everywhere.
