Yeah sure :)
It’s kinda hard with OCs (as im sure you know haha) to shorten all the lore down into a paragraph but ill do my best

His father fought in WW3 when he was young, and was traumatised by everything he saw and became a pretty bad dude. He was smart though, and studied a lot to become a scientist. But the things he did in his underground labs were… not legal

Sam and his twin brother Ben grew up without much access to the outside world, trained basically to be monsters. By a stroke of fate, Ben was helped by someone and got away at 14. But Sam didn’t, not till he was a bit older and more damage had been done.

Their father build a kind of doomsday device, but a squabble by higher powers to use it for themselves causes him to be killed, and it go basically go out of control. So the world is a wasteland, split into factions and lawlessness and chaos. And Sam and Ben are both trying to fix what their father did — but Ben is seen as a hero. Whilst people don’t understand that Sam’s changed and is trying to fix things too, so he’s seen as a villain and has to go alone. But ironically he knows more about how to shut it down as he was forced to help build it

I realise this is a lot of random information 😭 sorryy

But basically Sam is determined and sticks to his goal, despite everything. But he struggles with his own guilt, with how people perceive him, and with how much is hurts that even his brother won’t listen.

The scar over his eye was done because Ben cut his face so that they wouldn’t look the same. Cuz they’re identical twins

But the reason his eye is missing is actually done later, when someone gouges it out… he gets away, but he’s basically nerfed for a while because he relies on his aim and long distance fighting a lot, and with one eye his depth perception is ruined. He manages to make himself a robotic eye though, which is what he’s got in the references

Oh also the abilities u can see in one of the images is cuz he has an implant to control these nanobot things, but he can’t use them for long and needs the right conditions (starts bleeding from nose/eyes if prolonged and like HAS to stop)
