Mike Daniels has arrived.

The Green Bay Packers' defensive lineman has spent two decades obsessing over Japanese animation, otherwise known as anime, and now he has finally reached the mecca. It's Comic-Con 2017, where more than 100,000 die-hard fans of everything from gaming to comics to anime gather annually to live out the childhood fixations they never grew out of.

Daniels is here for the very first time and in cosplay, dressed as Raikage, a central character for the anime series Naruto.

He's in his element.

"This kind of stuff, it wasn't the cool thing when I was growing up," Daniels said at the start of his four-day adventure through Comic-Con last week. "Now, pop culture is comic books, super-hero movies, anime, manga, and I've been doing it for a long time."
