Falcon & The Winter Soldier: 10 Characters Who MUST Appear

9. Thaddeus Ross

With the inclusion of Wyatt Russell as John Walker in the series, there's little doubt that we'll be seeing his comic origins be adapted. In a nutshell, after Steve Rogers once gave up the mantle of Captain America, Sam and Bucky were passed over to pick it up in favor of Walker, whose turn as the star-spangled hero proved problematic, leading the character to give up the role and eventually become U.S. Agent instead.

As such, it only makes sense that - with the government certainly wanting to voice its opinion about Sam being the new Cap - Thaddeus Ross serve as the face of the conflict. After a long absence following his debut in The Incredible Hulk, Ross returned as the Secretary of State in Captain America: Civil War to spearhead the Sokovia Accords, something that helped fracture the Avengers ahead of Infinity War and Endgame.

An appearance by Ross in the series would go a long way towards clarifying what he's been up to during and since the Decimation, what the current situation is with the Accords, and what his thoughts are regarding a new Captain America. After all, it was Ross who dusted off Project Rebirth, the super-soldier program that created Cap, and created the Abomination, so it wouldn't be a surprise to learn that he's spent time trying to right that mistake for use on someone like Walker.
