War Machine
Also, War Machine develops a phobia of being trapped inside his armor (also based on a then-current comic storyline), but this is resolved before the final episode. While Rhodes was active as War Machine in season 1, he remained out of armor for the majority of season 2 due to reliving a tragic drowning experience while being trapped underwater in the War Machine armor in the season 2 episode "Fire and Rain". Rhodes eventually overcomes his fear and dons the War Machine armor once again in the episode "Distant Boundaries".
