A.N. — December 1 is a crowded day for birthdays. So, the next three drabbles are all characters born then. I chose to lead off with the least noteworthy of the bunch, IMO, and I'm sure the write reflects that. Supporting that argument: he's only got one name.

333. Sidero

Humarise didn't much care for people like Sidero. Not only did he have a quirk, his very body was evidence that the organization's main tenet was true. And, truth be told, Sidero didn't much like the group, either... or himself. Joining up was just a sanctioned way to vent his frustrations at the world while ensuring he wasn't culled due to his "disease."

Making other people miserable via his Iron Ball quirk was the only way it could possibly be construed that Sidero was having a ball at all. He just wanted to destroy others before he himself was eliminated.
