1-Up
From Homestar Runner Wiki
1-Up the extra man is Homestar Runner's 20X6 counterpart. Everybody says Stinkoman's the guy, but 1-Up wants to be the guy, too. However, he is often squished by Pan Pan, usually to Stinkoman's great delight. He also inherited a gross old wig from Homestar Runner. His name comes from the video game term for an extra life.
This character's name wasn't officially revealed until Stinkoman 20X6 debuted.
