Victor Chase Stein (also known as Talkback) is a superhero who appears in American comic books published by Marvel Comics. The character was created by author Brian K. Vaughan and 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 Chase's case, mad scientists. Chase tends to be viewed as the "wild card" in the series due to his shifting roles within the group (e.g. getaway guy, technical wiz, loose cannon). Chase, 18 years old, is the eldest of the Runaways. Chase shares a psychic and empathic link with dinosaur Deinonychus Old Lace, granting Chase the ability to command the creature. Chase also possesses the fictional world's most powerful gauntlets, Fistigons.Chase Stein was portrayed by Gregg Sulkin in the Hulu television series Runaways, which is set in the Marvel Cinematic Universe.
