Alex Wilder is a fictional character in the Marvel Comics series Runaways. He was created by author Brian K. Vaughan & artist Adrian Alphona, and debuted in Runaways vol. 1 #1 with most of the other main characters. Like every member of the original Runaways, he is the son of evil villains with special abilities; in Alex's case, gang mob bosses. Alex is the team's de facto leader in the title's first volume, temporarily ranking Alex among the list of African-American superhero team leaders. Unlike the rest of the team, Alex does not possess powers of any kind but is a child prodigy in the fields of logic and strategy, both of which assist Alex greatly during his time as leader. Thin, black, and with a signature afro, Alex outed himself as the Runaway's secret mole to their evil parents, and met his tragic demise after being blown into ashes by the Gibborim.
