Some TMNT stuff really isn't for little kids.
Maze is a member of the Street Phantoms gang and an associate of Darius Dun. Like all the Phantoms, she wears a special phasing cloak that allows her to phase through solid objects. Her signature weapon was an electrified knife.
She first encountered the Turtles when they raided a meeting between the Phantoms and a gangster named Lupo, but retreated as Dun did not wish them to be seen openly yet. After a Foot Assassin named Jennika contacted the Phantoms in order to betray Splinter, Maze accompanied Jammer to Foot Headquarters, where she lost her cloak and was knocked unconscious by Leonardo. She was carried away by her cohorts.
Some days later, she was again drawn into a trap when she, Jammer and Turk were lured to a parked truck by Donatello. As she was about to slash its tires, she was tased and knocked away by Nobody before fleeing the scene. She also accompanied Jammer when he kidnapped Harold Lillja, and was present as Dun attempted to recruit him, and during his escape.
Along with the other Phantoms, she attempted to stop the Foot Clan from invading Dun's corporate building, and encountered the Turtles on their way up. She fired an EMP gun at them, but was punched out by Nobody.
While she recovered her wits, Maze happened to hear Libby Meitner confessing to Harold that she still loved him and wanted to be his partner once again. She attacked Meitner with her knife, wounding her badly, but was once again defeated by Nobody before she could injure Harold.
Along with the other Phantoms, she was stripped of her mask and cloak by the Foot Clan, and witnessed Dun's execution on Splinter's orders. Afterwards, she was released.
