Marianne

Marianne is an obese italian woman and the cousin of Mario and Luigi, who perceive her as annoying; she bears a slight resemblance to Mario (they are both played by Lou Albano).

In The Super Mario Bros. Super Show! live-action segment "Marianne and Luigeena", Marianne, along with her apparent sister, Luigeena, calls Mario and Luigi on the phone and, after hearing Lyle Alzado would be visiting Mario Brothers Plumbing, decides to go over, much to Luigi's dismay.

Arriving at Mario Brothers Plumbing, Marianne and Luigeena notice that Mario and Luigi are not home, but Lyle Alzado is there instead. Marianne and Luigeena instantly begin trying to flirt with the disturbed Lyle upon seeing him.

After a while, Marianne manages to convince Luigeena to leave and look for Mario and Luigi, leaving her and Lyle alone. Continually flirting with Lyle, Marianne is eventually separated from Lyle by the recently appeared Luigi. As Luigi begins to try and explain things to Lyle, Marianne decides to leave to search for Luigeena, though not before reminding Lyle of their upcoming date, much to Lyle's horror.

Marianne, as well as Luigeena, appear again shortly afterwards to tell Lyle that her date with him was canceled, as the two had recently seen Mel Gibson and had decided to follow him home; the two then left, leaving a somewhat disappointed Lyle behind.
