From Homestar Runner Wiki
Stinkoman (also spelled Stinko Man) is Strong Bad's 20X6 counterpart. He is an amalgam of anime clichés. This includes having blue hair; big eyes; a blocky sort of body; a mouth that is very small when closed, very large when open, and out of sync with his speech (a parody of poor dubbing). He also has a tongue that is sometimes green, and an obsession with challenges and fighting. He was introduced on January 6, 2003 in the Strong Bad Email japanese cartoon, which makes his birthday fall exactly one week before Trogdor's. Even before the introduction of the Stinkoman character, his name was mentioned in island when Homestar Runner calls Strong Bad "Stinkoman". Stinkoman also stars in the game Stinkoman 20X6, which The Brothers Chaps introduced in the NYU Talk and later released on homestarrunner.com.
Stinkoman's theme song, which accompanied most of his early appearances and featured pseudo-Japanese lyrics (actually the words "Challenge" and "Fighting" repeated as if spoken by a Japanese person), was actually a background tune from the NES racing game Rad Racer. The composer, Nobuo Uematsu, would later be famous for the soundtracks of the Final Fantasy games and the main theme of Super Smash Bros. Brawl.
Stinkoman employs technology to arrange, engage in, and practice for his challenges. He has a cell phone which he uses to challenge Marzipan in Marzipan's Answering Machine Version 8.0. When the distance to his foes is too far, he whistles for the Stinkowing for transportation. According to alternate universe, Stinkoman uses his friend Vector Strong Bad as his "training simulator", but when he's not preparing for upcoming challenges, he relaxes by playing the Nintendo Entertainment System at Stinkoman Headquarters. Stinkoman's favorite foods appear to be chicken soup with dumplings, bread, power crunches, pudding, and prawns, as seen in Stinkoman 20X6.
Various facets of Stinkoman's persona refer specifically to characters in real-world popular culture. In particular, Stinkoman is very similar in build to the NES incarnation of Mega Man, who also had blue hair at one point. In fact, Stinkoman's sprite in Stinkoman 20X6 is a modified version of the original Mega Man sprite.
Stinkoman's lines, "Are you asking for a challenge?!" and "No way, you're just a kid! Maybe when you're older!" are very similar in both content and intonation to messages spoken by the Mega Man 8 boss Tengu Man: "Are you worthy of my challenge?" and "It's just a kid, don't make me laugh!" The line "No way, you're just a kid! Maybe when you're older!" is used several times in the anime movie Akira. The 20X6 and Akira connection appears again in an Easter egg in 3 Times Halloween Funjob. It is thought that his voice is based on Cam Clarke's rendition of Akira's protagonist, Kaneda.
When Stinkoman grits his teeth, plus signs (+) make up the cracks between them. The character Donkey Kong in the original Donkey Kong arcade game was also depicted with plus signs to indicate the separate teeth in his mouth. Finally, Stinkoman has worn the costume of another Japanese cartoon character, Speed Racer, as seen in 3 Times Halloween Funjob.
Stinkoman has a strange habit of eating dirt, such as when he finds the time capsule in the email of the same name. Additionally, in Under Construction, he tastes what he thinks is dirt even though it turns out to be pudding.
His trademark attack is the "double deuce", which shows him holding his "hands" in front of himself and shouting "DOUBLE DEUUUUUUUCE!!!" while a glowing aura surrounds him, similar to various attacks done by Goku in Dragonball Z.
