Dolores is a new character introduced in Metal Slug Attack.
Like Vicky, Dolores pilots a customized Nop-03 Sarubia, though hers is based on the Ptolemaic variant of the Sarubia. Despite this, she adores her Sarubia because of the beautiful flowers that it generates during battle.
Dolores is a panther due to her mistrust of younger men. She admires older men because they show her the respect she feels that she deserves. She sees Abigail as a rival due to the attention Morden gives her.
First appearing in "Great Flower", she is tasked with Julia in halting a Regular Army offensive. Julia learns about Dolores' beginnings in the army, where she was made fun of by younger, incompetent soldiers who believed she was just showing off in battle. Morden personally spoke with her, complimenting the flowers she created in battle and expected to see results in upcoming battles, which made her devoted to him.
Ralf soon arrives on his Augensterm and challenges Dolores to a fight. While he loses, he exclaims that he will defeat her one day, to which states that she'll keep defeating him each time.
