Edwina, but more often referred simply referred to as Ed, was the sister of Big Al and Bob, and owner of a small Roboshack on planet Hoven. She equipped Clank with the Hydro-Pack at Hoven by paying her 2,000 bolts. She has a strong affection for robots, as she adored Clank and hardly paid any attention to Ratchet, who had a small crush on her.
She spoke with a thick country accent and preferred to go by the more androgynous name of "Ed." She was with her brothers at the premiere of the latest Secret Agent Clank film at the end of Ratchet & Clank: Up Your Arsenal.
