Dolores is a villainous pilot in the Rebel Army and a playable unit in Metal Slug Attack.
Dolores was sent along with Julia to fight off a Regular Army attack. During their mission, Julia learns about Dolores' beginnings in the army, how she was made fun of by younger, incompetent soldiers who believed she was just showing off in battle but was personally complimented by General Morden for the flowers she created in battle, causing her to become extremely loyal to him.
Dolores and Julia are confronted by Ralf Jones on his Augensterm and Dolores is challenged to a fight. Dolores defeats Ralf, but he states that he will defeat her one-day. Dolores then replies that she will keep defeating him each time.
