Irritator's name comes from the irritation scientists felt when they realized that the original skull had been doctored with plaster to be elongated for a higher commercial value. Some reconstructions show Irritator with a crest on its nose instead of its head.

Manga

In the arcade website's Four-Frame Manga, Seth had Irritator use Life Swap on Zander and Ed, who had through shenanigans reversed their fat/skinny dynamic; the result removed Zander's extra fat, but sent it to Irritator instead of Ed.
In the actual manga's storyline, Ed gives the new Alpha Gang recruit, Rex, an Irritator to fight Max. However, Rex had only joined to save Max, so he and Max took the Irritator and escaped. Later, the Irritator started to talk and was later known as Benjamin.
