Maggie is a new character introduced in Metal Slug Attack.
Originally a civilian, Maggie joined the Regular Army so that she could take care of Molly after learning that she was unable to take care of herself. She cares for both Molly and Amber, and as such is seen as a motherly figure to both young women though she is roughly the same age as them. She enjoys cooking (despite not being assigned as a cook), with one of her signature dishes being lotus root with minced meat.
In battle, she pilots the Slug Rising and effectively uses its plasma weaponry. Maggie is also part of the Metal Device Project. She is also capable of repairing machinery on her own, having a small selection of tools held inside her jacket.
First appearing in "Try Line 8th", Amber calls Maggie after learning that Molly is having trouble trying to make a living in the army. Maggie subsequently enlists into the Metal Device Project since civilians are not allowed into a military base. She locates Molly's room, tidies it up and prepares food. When Molly regains consciousness, she is surprised to see her and believing she is still a civilian, Maggie shows her the enlistment paper. After eating, they set out to participate in the event.
Upon finishing the operation, Maggie asks a soldier to take care of Molly for her, much to the latter's embarrassment. Amber comes in and chuckles at the scene, though Maggie takes a quick look at Amber and believes she is not eating enough. She then forcefully feeds her a special cookie while Molly goes off to the Try Line shop.
Maggie is later seen cooking for the Regular Army and is confronted by Claudia, who tells her that she isn't on cook duty. Maggie appears to ignore her words and instead offers her some food; coupled with her sincere attitude, Claudia is soon unable to resist. Following an operation against the Sky Satan, Maggie later stumbles into Claudia and Ashley, offering them vegetable curry, the latter of which eagerly helps herself to some.
