Gertrude Yorkes (self-referred to as Arsenic) is a fictional character in the Marvel Comics award-winning series Runaways. She 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 she is the daughter of evil villains with special abilities; in Gert’s case time-travellers.
