Comic-Con starts today and in honour of the comic world's über fans, we've rounded up 25 of the craziest comic tattoos out there. You won't believe just how dedicated some fans are — we're talking The Joker's face on your forearm. But if you're thinking your look is more Chanel than Captain America, need we remind you that Angelina Jolie and the Glee crew were just some of the A-listers in attendance last year, and this year, Ryan Kwanten and Emma Stone will be channelling their inner geek!
