Advertising: Segata Sanshiro

You'd better run, boy.note 

In the 1990s, Hiroshi Fujioka played the eponymous Segata Sanshiro (pictured), the Japanese spokesman for Sega's Saturn console - a crazed martial artist who beat the living crap out of kids for not playing Sega Saturn and singing his own theme song (well, part of it), which was later released as a single that sold over 100,000 copies. It can be argued that his presence in Sega's Japanese commercials was singlehandedly responsible for the continued existence of Sega in the console market (up to the Sega Dreamcast).

His last commercial consisted of him bravely sacrificing himself to ensure the Dreamcast's release, and his exploits were immortalized in Sega's last first-party Saturn game Segata Sanshiro Shinkenyugi.

His exploits have given him a Memetic Badass status comparable to Chuck Norris, except this guy has video footage to back the claims up. The two faced off, with the end result being the two tying, and breaking the universe in the process.

He was one of the three winners for the voting of DLC characters in Sonic & All Stars Racing Transformed.

He made his American comic first appearance in Archie Comics' Sonic the Hedgehog issue #269.

A collection of the commercials can be found here.

The Segata Sanshiro commercials provide examples of:

Troper: "Oh yeah. Now what trope do I have to see..." (someone taps his shoulder) "Look, I'm kinda bus— S-SEGATA SANSHIRO!?"
Segata: (beats Troper to a pulp for contributing to tropes rather than playing Sega Saturn)
Troper: "S... Segata Sanshiro..."
Segata: "Sega Saturn, shiro!"
