Warren is a character from the comic series Matt and Tyler.
Warren was the weirdo oddball kid and a classmate of Matt, Tyler, and Aaron. He was planned to be a recurring character in the series, but the cancellation prevented that from happening. Warren was still able to make two brief appearances in the series and Warren's odd personality is easily identified in both appearances. His first appearance is in the first episode and he is shown streaking around the school in his boxers. His second appearance is in the final episode and he is showing himself off around the school in lederhosen.
If the series had continued, Warren would of been shown doing various odd activities and freaking out the main cast with his weird traits. Warren was intended to have blond hair.
