Gertrude Yorkes (self-referred to as Arsenic), is a fictional character in the Marvel Comics 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. Gertrude, often called "Gert" for short, is often regarded as the most "book-smart" of the Runaways yet also the most sarcastic and cynical. She has socialist leanings and is ethnically Jewish but spiritually agnostic. Gert is known for her sarcastic one-liners, a pair of glasses, and brown dyed purple hair. She stands at a rough height of 5'1" and weighs 125 lb (57 kg).
In 2008, Marvel.com named Gert's death as the sixth out of ten best deaths in Marvel Comics history.
Do you still keep my pictures in your frame?
Cause I still shut down with the sound of your name.
Do you still wanna talk to me like you used to?
Cause I could understand if you don't
I Wont... Call unless you call me first
Do you still keep my letters in your drawer
Cause I still have yours but I don't read them anymore
Do you still wanna kiss me like you used to
Cause I could understand if you don't
Do you still hold me close to your heart
Cause I still need you even though we are apart
Do you still wanna hole me like you used to?
