The random Paper Mario generator generates characteristics of a randomized Mario-series character using a series one or more catalyst words. It generates multiple factors for a character, including gender, species, and dominant humor. It was programmed by gestaltScribbler and can be found on Memegen.net.
The 'Sign' portion is a possible reference to a Paper Mario Zodiac that gestaltScribbler created (2) however there are different signs in the generator than on the page. gS planned to describe what the signs meant, however he has not at the time of this edit.
