If you're looking for a crazy yet fun guy (get it?) to hang around with, EDjr is for you. He is Sage's friend, and is usually the one who gets into all kinds of trouble. Oh, and if he gets too crazy, he'll turn into some form that looked like he was in a Ren and Stimpy cartoon!
Jack is your ordinary calm yet bold person, always looking for adventure.
His mute, but bright partner, The Super Star, originally came from another dimension in space, before he crash-landed on earth and met Jack as a youngling.
The geeky girl you'd like to hang out with. She's really into cats and video games, but what she's really into is finding the portal to a secret land that we shall dare not mention...
A master scientist and Sage's arch-nemesis. While he is as intelligent as him, he's also quite a boastful person, wanting all the fame and fortune for his accomplishments.
