Agalia is a new character introduced in Metal Slug Attack.
Agalia is a vampire who helps others of her kind from humans. She is unfamiliar with human civilization. She is very prideful and dislikes using underhanded tactics.
As a vampire, Agalia enjoys feasting on blood. Unlike Aswang however, Agalia is capable of feeding without coming into physical contact. She normally appears as a typical vampire, but if she has acquired enough blood, she can "transform" into a more human-like form which resembles a young girl.
She first appears in the second United Front, where she battles a large group of enemy soldiers since she is hungry. After killing them, she departs from the battlefield.
Sometime later, she would eventually manage to bring Vatn under her control by drinking his blood. However, this cost her a considerable amount of energy in both transforming and controlling him, so she was forced to assume her human form. Despite her control over him, it was not complete and Vatn occasionally showed signs of disobedience.
During one of their missions, she learned of a Sky Jupiter Queen holding a considerable amount of energy. Since she was still weakened, she had Vatn destroy the machine to collect its energy, though he refused to chase after Caroline and Dragunov, who successfully escaped.
- She is simply named "Vampire" in the game's files.
- Her special variant color scheme is referenced to Athena, a 1986 SNK platform arcade game with the same name.
