Ross Marquand

Roscoe Wayne Marquand (born August 22, 1981) is an American actor and impressionist. He has played Aaron on the television series The Walking Dead (2015–2022), Red Skull and Ultron in various projects connected to the Marvel Cinematic Universe, and voices numerous characters in the adult animated television series Invincible (2021–present) and X-Men '97 (2024–present).

Early life Marquand was born in Fort Collins, Colorado. His initial foray into acting began at the age of nine when he played a small part in a church play. Soon thereafter, he joined the Boy Scouts of America (where he attained the rank of Eagle Scout) and began impersonating celebrities at campfire ceremonies.

According to Marquand, he suffered from bullying in his youth due to being part of "all nerdy things" such as the Boy Scouts, the student government and the chess club. When he was 11 years old, Marquand watched X-Men: The Animated Series and "fell in love" with the show, taking a particular liking for Wolverine due to all the pain and pathos within his character. Wolverine's line "There's no peace for me here. There's no peace for me anywhere" marked Marquand's life, making him feel like if he could convey a shred of what Cal Dodd could do with Wolverine, that's what he wanted to do in life, deciding to pursue acting.
