When the Doctor regenerates, anything is possible, right? In Katherine Sudy’s Doctor Who tattoo sleeve, the timey wimey realm of the TARDIS is combined with Pokémon to give us memorable imagery—like an Ood holding a Poké Ball and Pikachu as the the fez-wearing Eleventh Doctor. No, really.

Sudy got the idea for the Who and Pokémon crossover because of a present she received in a redditgifts exchange. Redditor dragon71 drew an Ood holding a Poké Ball and that spawned ideas for Sudy and her tattoo artist Billy Bubbles Tattoos. She gave Billy guidelines and he did his own renditions of all the art.

The strictly Pokémon sleeve took around 15-20 hours to complete, with the Doctor Who-leaning sleeve clocking in at about 25 hours.

Time travel to the gallery below to get closer looks at the various elements of the tattoo, including Gyrados, a Bad Wolf (note the inclusion of a rose as a tribute to Rose Tyler), a Doctor Dalek, a Dr. Horrible quote, and more.

If you have nerdy ink on your skin or you’re a tattoo artist that applies pop culture, STEM, music, or other nerd-inspired ink (tl;dr: I want to see basically all of the tattoos—not only Star Wars ones) on a regular basis, then please hit me up because I’d like to highlight you in a future Inked Wednesday gallery. I’m especially interested if you have a sleeve or other large tattoo. You can get in touch with me via email at [email protected]. Send me photos of the tattoos you’d like me to feature (the higher resolution, the better) and don’t forget to let me know the name of your tattoo artist if you have it, as well the name of the shop he or she works out of. If you are the tattoo artist, give me links to your portfolios and/or Instagram accounts so I can share them with our readers.
