I acknowledge Spawn and Black Panther.
Falcon--he is a one dimensional character and moreso a sidekick rather than a stand alone hero.
Cage--he is your idea of white people trying to be "cool" and revamp an urban black hero. Stereotypical, can't stand him.
Cloak- has great potential to develop as a character but not used oftenly enough.
Maxim--He is just a Thanos/Hulk rip off and appeared briefly in the Infinity Crusade saga.
Rhodes---Don't see him as an important figure and he is just a spinoff from a much more famous character. He was Stark's lackey/buddy/confidant.
