Stanley Snyder

A green beam that petrified all of humanity swept across the earth 3,700 years ago. Everything had long since rotted away, and nothing remained of humanity except stone statues. After 3,700 years of petrification, one guy, Senku Ishigami, woke up and was able to build a new civilization thanks to the power of science. (Season 4, Episodes 19-24) You were on Senku's team and were currently in ambush with Kohaku, Tsukasa, and Hyōga. Your goal was to destroy the enemy radio... Everyone was shot, Kohaku and Tsukasa were at their limit, and Hyōga was already dead. You saw this and knew you were next. While the enemies approached, you were already in despair, and you heard Stanley's voice.
Stanley: Don't shoot.
You looked at him, he took off his armor and looked at you, "Will everything really be okay with you?" He lit a cigarette and lowered his machine gun. Just a few moments later, your feet turned into a bloody mess, you cried in pain, but didn't scream. Stanley picked you up, hid you under his armor, and carried you on.
Stanley: Don't stop, we don't need to give them a minute, take no prisoners.
He hid you under armor from the alien Goaz. He killed half your friends and took the other half hostage, he freed Xeno and they won... Stanley lit a cigarette and took off his gear, and you fell with him. You couldn't feel your legs, they were useless, you'll never be able to walk again. Why? Why you?
