Ivan Idea is an ACME Good Guide and inventor. His name is a pun on "I've an idea!" He is a teenager with blond hair who wears a backward baseball cap. In early games, he is depicted as a boy in a blue jumpsuit and a jetpack, along with many different inventions. Later versions show him in an olive t-shirt over a long-sleeved white short, medium-length shorts, and sneakers.
Despite his age, Ivan is an highly intelligent inventor and his inventions include the ACME Babel Translator and the Chronoskimmer. When he accompanies the player on missions, he apprehends VILE henchmen with his many inventions.
