Lizzie first appeared in the 1986 game, Rampage
, and has since appeared in every Rampage game to date. In the series' previous games, she resembled a Godzilla-esque dinosaur, but in Rampage: Total Destruction
, she grew shorter and has a more cartoony, exaggerated appearance. Her bio stated she was a scientist at Scumlabs and was somehow mutated along with George and Ralph into giant monsters.
