Codec Conversations

Codec Conversations is a series of easter egg conversations in Super Smash Bros. Brawl. The conversations are triggered when Snake performs his down taunt on Shadow Moses Island without being attacked for at least five seconds of the animation. The conversations feature Snake consulting either Colonel Roy Campbell, Mei Ling, Otacon, or in one case, Slippy Toad, regarding the fighter he is facing in a given match. Codec Conversations can only happen once per match. It is currently unknown if they will return in Ultimate, and if so, whether they will reuse the Brawl conversations.

They reference conversations between Snake and his support team in Metal Gear Solid/The Twin Snakes, even reusing the same portraits of the characters from that game. Mei Ling, another character from Metal Gear Solid, joins them in some conversations, as do Otacon and Slippy Toad in others. The discussions are light-hearted in nature, and often contain references to the character's respective franchises. Palutena's Guidance is triggered in the same fashion as the Palutena's Guidance had by Pit on Palutena's Temple in Super Smash Bros. for Nintendo 3DS and Wii U.

Samus

 * Snake: Hey, Otacon. I got a woman here in a Power Suit...


 * Otacon: Huh? How'd you know she was a woman? Yeah, that'd be Samus Aran, the most renowned bounty hunter in the galaxy. Her Arm Cannon packs quite a wallop. If you get hit with a charged shot from that thing, you can kiss your butt good-bye.


 * Snake: Sounds like my kind of woman...


 * Otacon: Yeah, well, just don't get too close, Snake. Samus is deadly. After Space Pirates killed her parents, she was raised by the Chozo and trained in the fighting arts. She's been places and seen things that you and me can't even begin to imagine.


 * Snake: But underneath that cold, metal exterior beats the heart of a woman...

Aside from it indirectly referencing his deducing Meryl in disguise as a Genome Soldier in his debut game, and to a lesser extent foreshadowing the Beauty and the Beast Unit in Metal Gear Solid 4: Guns of the Patriots (which had been in development at the time Brawl was released), the beginning remarks, in particular Otacon's surprise at Snake deducing Samus's gender, also alluded to how in the first game, Samus's gender had been kept secret until the ending.

Zero Suit Samus

 * Snake: Mei Ling, Samus took her clothes off!


 * Mei Ling: That's just her in the Zero Suit, Snake.


 * Snake: Without that bulky Power Suit, she's gotten a lot more agile... You know, I bet if I took off all this heavy gear, I could catch her.


 * Mei Ling: Um, yeah, you wish. Even without the Power Suit, all that training she did with the Chozo has made her a super athlete. I don't think a normal human could ever keep up. Just look at her.


 * Snake: ...Her loss.

Snake's remark about Samus taking her clothes off was slang for nudity, and was an indirect reference to how the best endings in the Metroid franchise generally had her in revealing attire. Although technically true that she had trained with the Chozo, the conversation neglected to mention that a large part of her superhuman abilities were the result of being infused with Chozo DNA to survive on Zebes.
