Colonel Roy Campbell
Colonel Roy Campbell is a character from the third-party developer and publisher, Konami. Campbell is from the stealth-action video game series, Metal Gear, debuting in Metal Gear 2: Solid Snake. He makes background appearances communicating with Solid Snake through his Codec device in Super Smash Bros. Brawl. Referred to simply as "Colonel", Roy Campbell appears in the first SSBB trailer, during which Snake is officially announced as a playable character. Like Otacon and Mei Ling, he also appears in a number of Snake's Codec Messages, which can be seen and heard mid-game on the stage Shadow Moses Island. Colonel's frequency in the Metal Gear franchise is 140.85 (although the frequency changes frequently in Metal Gear 2), and the same frequency is used in Brawl.
At the end of the first official SSBB trailer at E3 2006, which only has Japanese dialogue (but English text and subtitles), Solid Snake is shown receiving a Codec message from Roy Campbell. The trailer contains the following English subtitles during the Codec conversation:
On the stage Shadow Moses Island, players using Snake can activate a Smash Taunt by pressing the button for a down taunt very quickly. Executing this correctly displays a Codec message in which Snake speaks with Otacon, Mei Ling or Colonel Roy Campbell about a character he is fighting during the match. He speaks with Roy Campbell about Bowser, Fox, Ike, Jigglypuff, King Dedede, Luigi, Mario, Ness, Pokémon Trainer, Wario, Wolf, Zelda, and Snake when he fights another player who is also using Snake. Originally implying to call the Colonel, Snake talks to Slippy Toad when discussing with him about Falco. Slippy Toad's frequency is also 140.85, but this is simply because Slippy had overridden Campbell's frequency, a recurring element in the Metal Gear franchise.
