Sam and Dean
FFN: Those matching tattoos are pretty cool. How long has that been planned?SG: I remember talking about it with Ben Edlund last season, while Cat was writing "Born Under A Bad Sign." We agreed that if we were Sam, the first thing we'd do is take that anti-possession amulet and head for the nearest tattoo parlor. He reminded me of it while we were working on “Jus in Bello,” because breaking out the amulets was an important story point in that episode. So I stuck it in there, and it made for a nice moment. It’s like, of course Sam and Dean have matching tats. How could it be any other way? By the way, I'll be convinced we're truly a cult hit when a fan gets the same tattoo.
Little did Sera know, that fans had been getting tattoos since early on in the Show's run.
- See Fan Tattoos for a gallery of Supernatural inspired tattoos from fans. The anti-possession tattoo is one of the most popular designs.
In 4.18 The Monster at the End of This Book, this phenomenon is referred to when Sam and Dean reveal their tattoos in order to pass as avid fans. In response the publisher of the Supernatural books by Chuck Shurley, reveals she has the same tattoo - on her ass. While not named in the episode, the publisher's name was Sera Seige, named after writers Julie Siege and Sera Gamble - as mentioned in this interview by Sera Gamble.
In 7.20 The Girl with the Dungeons and Dragons Tattoo Charlie reveals she has a tattoo is of Princess Leia in her slave girl bikini astride a 20-sided dice (which are used in RPGs). In a scenario familiar to many fans, she claims she got it while drunk at Comic-Con.
Kevin and Linda Tran
In 8.02 What's Up, Tiger Mommy? Sam and Dean make both Kevin and his mom Linda Tran get anti-possession tattoos at the Inked Pig Tattoo Parlor. Linda admits its not her first. Later Plutus' assistant Beau burn off Linda's tattoo so that Crowley can possess her. During 9.06 Heaven Can't Wait, Kevin's tattoo is visible as he draws his blood so Crowley can call Hell.
In 9.03 I'm No Angel after Castiel becomes aware that angels are hunting him, he gets a tattoo in Enochian which will make him unable to be tracked by angels. This is similar to the Enochian sigils he burned into Sam and Dean's ribs for the same purpose in 5.01 Sympathy for the Devil. However, this tattoo just jams him from being sensed by an angel's normal means of sensing people, Ephraim is able to locate him by sensing his pain showing the tattoo doesn't block everything.
