Who he is: Chester Phillips
His power: No powers, just an old-fashioned military man.
His story: Colonel Chester Phillips is first introduced in Captain America: The First Avenger as the man in charge of training the candidates for the super-soldier program, scornful at first of Steve Rogers’ presence, but slowly accepts his potential. After Rogers is put through the treatment and the serum’s creator, Dr. Abraham Erskine, is killed by a Hydra agent, Phillips returns to the front, having assumed Captain America would perform as a kind of show pony to raise funds for the war. However, after Captain America deserts his post and singlehandedly rescues an entire unit of men from Nazi control, Phillips finally respects him—even doling out a salute, which as everyone knows is very rare for grizzled old military guys who don’t take any guff. He then aids Captain America again in the final infiltration of the Red Skull’s facility, and convinces Dr. Arnim Zola to come work for the Americans. (Although, that last thing doesn’t work out so well in the long run.)
Played by: Tommy Lee Jones
Currently, Chester Phillips is: Long dead, as are most of the characters from the ’40s-set Captain America.
Where will we see him next? Likely never.
