- "Jeff, wait. How... am I supposed to find this Rick? I don't even know your last name. Where does he live, Jeff...? Jeff?"
- —Claudia asking Jeff about his brother.[src]
Nothing is known about Claudia's life prior to or as the outbreak began, except that she worked as a curator in Barcelona.
She was working as a curator when the apocalypse hit. Her assistant had turned and bitten a security guard at her work before she escaped with a suit of armor. She met Jeffrey Grimes and the two attempted to escape to America on a boat. She fell into the water attempting to kill a zombie, and Jeff saved her life before revealing he was bitten. He tells her to deliver a message to his brother, Rick, but dies before she could know anything more about him. It is currently unknown what has happened to her since.
This list shows the victims Claudia has killed:
The two met in Barcelona after the outbreak. They seemed to have a good relationship, as they both saved each others lives. Jeffrey also asks Claudia to deliver a message to his brother Rick as his last wish.
- It is hinted in Letter Hacks that Claudia might appear again in the Comic Series.
- This never occurred, however, as the Comic Series ended with Claudia never being heard from again.
- During the online panel Comic-Con at Home, Kirkman jokingly stated that Claudia had been eaten by a whale shortly after the events of the comic.
