Suicide Squad. It was poopy but can be watched if you are bored. Here is a list https://tribecafilm.com/stories/sup...war-super-james-gunn-unbreakable-bruce-willis
Unbreakable is getting a sequel called Glass in 2019. It has a sidequel called Split that came out January 2017.
I would like to point that out typically the protagonist refers to the perspective character as opposed to the "good guy." So the MC would still be a protagonist as opposed to antagonist. You might be looking for antihero or villain protagonist.
an·ti·he·ro ˈan(t)ēˌhirō,ˈanˌtīˌhirō/ noun a central character in a story, movie, or drama who lacks conventional heroic attributes. AKA the hero you only call because Batman, Superman, Spiderman, the Xman, (even Aquaman) aren't available. Because your city already has one villain, you don't need more shit exploding and body parts flying everywhere. Even then they might not show up. Because Antiheroes are dicks most of the time. And Antiheroes can be villains some of the time. Like Deadpool (has been a villian quite a few times in comic books due to his mercenary/asshole-ish nature), Deadshot (mercenary/assassin nature + cleans up his act later on), Deathstroke (merc nature + code of conduct). Hell, I even consider the first Ironman movie antihero. He killed a shitload of terrorists later on for revenge + equipment testing.
