Amelia is a free spirit, independent, and mostly does what she wants regardless of other people's thoughts and feelings. She has a penchant for fire and explosives - likely a bizarre coping skill given an event in her past. She wears a gas mask at all times to conceal her disfigured face, only removing it for people she deeply trusts. She despises alcohol and drugs and gets upset if such things are consumed around her. 

Amelia's family immigrated from Mexico when she was a little girl. While she had a happy childhood with her mother and brother, he father was involved in the criminal underworld and owed a vast sum of money to drug dealers. In retaliation against her father, Amelia's family home was burnt to the ground with everyone inside. Her entire family perished in the blaze, but Amelia managed to crawl to safety. She was further disfigured by the criminals to serve as a cruel reminder of what had happened. She ended up homeless for many years as a young adult, shaping her into the street-smart individual she is today.
