Metal Gear Solid 2: Sons of Liberty/Trivia
- Executive Meddling: You might be wondering why Raiden's codename in Japanese is written in Kanji instead of Katakana like the other characters or his real name. That's because the Katakana variation of his name sounded a bit too close to "Ladin" (as in, "Osama Bin Ladin," the leader of al Qaida and the mastermind behind 9/11) for people's comforts due to the game having a similar plot to the 9/11 attacks, and it being released just a few months after the 9/11 attacks.
- Hey, It's That Voice: A meta example. Rosemary's Japanese voice actress also does The Boss and Sunny.
- Her English voice actress apparently voiced Lilah in the Ctrl+Alt+Del animated series.
- The Other Darrin: Going by pre-release info, Raiden's going to be voiced by Toshiyuki Morikawa in Metal Gear Solid Rising. And according to Quinton Flynn's official site and Twitter, he has yet to be approached to reprise the voice. However, the English trailer for Rising confirms that, yes, he is still going to be voiced by Flynn.
- Similarly, in the English version of Secret Theatre film Metal Gear Raiden: Snake Eraser, Raiden was voiced by Charlie Schlatter (in other words, Raikov) instead of Quinton Flynn either because he was unavailable or the localizers wanted to make the similarities between Raiden and Raikov more apparent.
- Talking to Himself: Sort of. Raiden doesn't share any voice actors with anyone else in Metal Gear Solid 4: Guns of the Patriots, but his motion capture actor also portrayed Little Gray, the monkey sidekick of Drebin 893. In fact, his motion capture actor was literally the reason why Little Gray was added into the game.
- What Could Have Been: Vamp was originally supposed to be envisioned as a woman, but for some reason, his gender was changed in development. Also, he was originally supposed to be, similar to a real life Vampire, afraid of the crucifix, although it was mostly due to the trauma he experienced when the church he was attending in Romania was bombed with him and his family in it, where he actually was impaled by one.
