With San Diego Comic Con this week, we're taking a look at some of the best celebrities who join in the cosplaying fun.

Cosplayers come in all shapes and sizes, and with celebrity cosplayers, they range from independent movie actresses, to TV stars, to WWE Superstars. Here are some of the best celebs who like to dress up as other characters at cons and events.

To be clear, we are only featuring celebrities who cosplay, not cosplayers who have become celebrities for cosplaying. As great as they may be, we won't be featuring beloved cosplayers like Meg Turney or Leanna Vamp here. Also, dressing up for Halloween doesn't count here.

    Bryan Cranston

    'Breaking Bad' star Bryan Cranston has made a name for himself as an expert 'Breaking Bad' cosplayer, with he and co-star Aaron Paul attending events and cast parties cosplaying as each other's characters and other characters in the show. But the pinacle of Cranston's cosplaying was during San Diego Comic Con a few years back when a man walked on stage wearing a life-like Walter White mask, only to be revealed as Cranston himself.

    Jamie Lee Curtis

    Jamie Lee Curtis isn't a regular cosplayer, but when she does, she goes all out.

    Molly Quinn

    Former 'Castle' star Molly Quinn is a regular SDCC attendee and cosplayer, attending the event as an original Star Trek crew member, Supergirl (whom she voiced in an animated feature), and as a gender-bent version of Malcolm Reynolds from 'Firefly', the role made famous by her 'Castle' on-screen father Nathan Fillion.

    Adam Savage

    The former Mythbuster is probably the king of celebrity cosplaying, being so good with his costumes that he goes completely unrecognizable during SDCC. Many SDCC attendees don't even know they saw Savage at the event until he posts the pictures to Facebook and Twitter with #AdamIncognito.

    Savage also performed a Ted Talk about his love for cosplaying.

  • Tara Strong Facebook

    One of the most beloved voice actors working today, Tara Strong is making a name for herself as a cosplayer by bringing her animated characters to life. Attending cons dressed as Batgirl and Twilight Sparkle from 'My Little Pony', Strong turned the most heads by showing up at her most famous character, Harley Quinn from the 'Arkham' video game series.

    Julia Voth

    Being totally honest here, we're stretching the definition of 'celebrity' here with Julia Voth. Voth's acting career isn't really A-list, appearing in several independent movies and one-off television guest spots. But she deserves inclusion on this list for who she cosplays as.

    While 99.9% of people may not recognize the name "Julia Voth", many gamers will recognize her right away as Jill Valentine from 'Resident Evil'. At 17-years-old, Voth provided the motion capture and facial model for the character of Jill Valentine in the 2002 'Resident Evil' remake for the Nintendo Gamecube. After the success of the game, Voth's likeness continued to be used as the official look of Valentine, and Voth embraced the character and began appearing at cons dressed as Valentine from the various games.

  • WWE & Xavier Woods Facebook

    WWE Superstar Xavier Woods has cemented his status as one of the best paid geeks in the world today. A child of the 90s, Woods uses many geek icons in his professional wrestling career, modeling his original attire after Power Rangers and shouting "Its Morphin' Time!" during his matches, and coming to the ring with his hair done up as Rufio from 'Hook' or Ruby Rhod from 'Fifth Element'. Gaining fame as a member of 'The New Day', Woods and his partners have shown up at Wrestlemania dressed as characters from 'Final Fantasy' and 'Dragonball Z', but also attending cons in his free time dressing up as Quailman from the cartoon 'Doug', Sub-Zero from 'Mortal Kombat', and even fellow WWE wrestler Bayley, just to name a few.
