Lunch Lady Ghost
The Lunch Lady Ghost is a fictional character in the Danny Phantom cartoon. She likes meat, and she gets angry when the menu is changed to a stricly vegan diet. She is voiced by Patricia Heaton and later by Kath Soucie.
The Lunch Lady Ghost may have once been a cafeteria worker at Casper High. She rose from her grave when the menu at Casper High was changed to a vegetarian menu. When she discovered that Sam Manson was the one who changed the menu, she makes the meat in the kitchen come to life and attack Sam (and everyone else present). Then, in the hallway, Lunch Lady Ghost covers herself with a meat battlesuit to capture Sam, and puts her in the freezer. When Danny and Tucker come after her, she attacks them as well. At outside the school, Lunch Lady Ghost makes an attack by controlling all the available meat, causing it to become a huge meat monster. When Danny defeated the meat creature, she summons little meat minions which he also defeats. In the end, Danny sucks Lunch Lady Ghost into the Fenton Thermos.
Her personality constantly shifts between a 'sweet old grandma' to 'vengeful spirit' (with voices to match) constantly. Either this means she has a split personality disorder or has a short temper.
In Prisoners of Love, the Lunch Lady Ghost serves lunch in Walker's prison. Then, she and all the ghosts teamed up to escape.
In an alternate timeline, she and The Box Ghost have a daughter named Box Lunch.
The Lunch Lady Ghost's powers
The Lunch Lady Ghost has ghost powers (intangibility, overshadowing, invisibility, and flight). She has a main ability to control meat, and to use it for her to become a meat monster. Lunch Lady Ghost also can control meat while invisible, as she did in Mystery Meat and Reign Storm. In Prisoners of Love, the lunch lady can summon a meat weapon.
