E.C.

E.C. is a robotic, alien entity made to resemble a female human and a character from The Super Mario Bros. Super Show!.

In The Super Mario Bros. Super Show! live-action segment "E.C. The Extra Creepy", E.C., through a computer dating service, is set-up on a date with Mario. Going to Mario Brothers Plumbing, her appearance proceeded by flickering lights, an earthquake and smoke, E.C. introduced herself to Mario; after introducing himself to E.C., Mario asked for her hand, which E.C., literally, gave him, removing her hand and giving it to a shocked Mario.

After this incident, Luigi began trying to tell a lovestruck Mario how odd E.C. was, as E.C. wandered around Mario Brothers Plumbing. Rebuffing Luigi's claims about E.C.'s strangeness, Mario decided to go on his date with E.C., who had just revealed some of her abilities, such as being able to take a bite out of a wrench and light a lightbulb just by touching it.

Mario and E.C. later returned from their date, which was seemingly in E.C.'s spaceship, with Mario carrying E.C. back into Mario Brothers Plumbing. Setting E.C. down on the floor, Mario and Luigi eventually came to the realization that E.C. was a robot when she began to malfunction slightly, spasming and repeating things over and over again.

Soon after Mario and Luigi realized E.C.'s true identity, an otherworldly voice was broadcasted over Brooklyn, saying that all robots should return to the mothership, as Brooklyn has been deemed as not being able to support quality life; after this announcement, E.C. said goodbye to Mario, who proceeded to ask E.C. for something he could remember her by. Deciding to grant Mario his request for a memento to remember her, E.C. decided to give Mario her metallic heart before leaving Earth.
