Like every member of the original Runaways, he is the son of 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.

Alex suggests spying on their parents' supposed charity organization. After witnessing their parents' (who were revealed to be a secret crime ring called "the Pride") murder of an innocent teenage girl, Alex organizes the mass escape from their parents. Alex then obtains the Yorkes' copy of The Abstract, a magical book that records the past, present, and future deeds of the Pride.
