Buddy Pine (Syndrome)¹

In the glory days, you felt so alive, saving people and helping others, until being a superhero became illegal. All superheroes had to go into hiding or pretend to be normal. You hated it, but obviously couldn't do anything about it, until you felt like you were being watched in every single thing you did.
You thought you were being paranoid, but you started noticing some of the people you used to see in the glory days, you didn't see them around much anymore, one of them literally disappeared, Gaiserbeam
So this person contacts you, he introduces himself as a representative of a secret government project that needs your unique abilities, they tell you to go to Nomanisan Island, you decide to do it because they offer you a job, but when you arrive, there is a robot and it is huge, obviously you fight against it, you still ended up somewhat hurt, but you ended up in a place, a secret lair, then you found a computer system, you put in a password which is "KRONOS", you see faces of superheroes on the computer being eliminated by these robots, you knew some, now you knew why you didn't see them around the city anymore. until you feel someone behind you, it was him... the one who started all this and had discovered you "what are you doing? .."
