I'm adding the Avengers 2 characters because I like them and can lol.

Captain America-Baron (In the thirties of Gaim he was a great leader)/Zangetsu (He was the leader of Yggdrasil and if everyone didn't betray him can be a good leader, also has the shield).
Nick Fury-Garren (has a gun, runs an Organization with an anagram, and lost an eye in a sense lol.)
Hulk-Another Agito (He's a Doctor and He went uncontrollable at times, had depression and rage issues like the Hulk and being an Agito has a lots of strength.)/ZX (Was part of an experiment, and definitely has a lot of power and Rage issues after what happened to him especially what happens in the Spirits Manga.)
Black Widow-Satonaka/Kiriko (Black Widow doesn't have powers and these two women are extremely well-trained.)
Hawkeye-Riderman (Was evil in the beginning then went good, kind of similar to Hawkeye's comic origin and similar to the movie being possessed. Also his different arms work like different arrows.)
Iron Man-Kabuto (Smart, Cocky, and thinks he's God, pretty sure that describes both Tendou and Tony.)/W (Both Shotaro and Philip together they combine for both the Cocky side of Tony and the Smart side of Tony. So definitely could work.)
Thor-Decade (They come from different worlds both have to deal with 9 Worlds/Realms, insanely powerful and both can be arrogant and helpful.)
Quicksilver-For just the speed Drive/Accel. For the Speed and close to the character and speed I'll go Kick Hopper/Faiz.
Scarlet Witch-Wizard (because of Magic)/Gaim (because of his God-like powers now and kind of similar personalities).
Vision-OOO (Not an android-like being but definitely has the similarities with the multitude of powers.)
