Rogers later meets and trains Sam Wilson, who becomes the superhero the Falcon, the first African-American superhero in mainstream comic books. The characters established an enduring friendship and adventuring partnership, sharing the series title for some time as "Captain America and the Falcon". The two later encounter the revived but still insane 1950s Captain America. Although Rogers and the Falcon defeat the faux Rogers and Jack Monroe, Rogers becomes deeply disturbed that he could have suffered his counterpart's fate. During this period, Rogers temporarily gains super strength.
