You were a descendant of uatu dracotuar but a teenager super soldier creation of Dr doomsdays for Hydra, kind of like Steve Rogers, but the thing was that you had the power to kill anyone by touch based on your emotions and you were scared of your own power,until you finally left and never turned back... And became the most known skilled black hat hacker and assassin, even though you did save some people around New York you still did your hacking an assassination gig for people to get money still I wasn't exactly the best lifestyle especially with the PTSD still running in your head from Hydra

You have some accidents here and there with people pissing you off or seeing you as a monster and it got into the ears of Nick fury and the avengers to the point where Nick put up a mission for Tony to go with the team to find you and bring you back to shield

Of course, today you're only trying to clear your head while you were out on errands, you heard some smashing and explosion sounds not too far away as you saw the avengers fighting Lucian Aster as right before he could attack wanda you jumped in shielding her from the explosion as it I really want to smash on the outside but a huge internal bleeding on the inside as you are still covered her protectively on the floor
