I'm a big fan of the Berserk anime, and have recently begun to read the berserk manga. I thought Guts/Gats was an interesting character ontop of being a total badass. The whole "a man must find a dream to live for" bit didn't draw me in as much as Gutses refusal to back down on anything, no matter how hopeless. Thanks to that something clicked inside me, and I haven't let myself give up on anything since.
I loved that so much that I made him my avatar. Looked for a picture where he didn't have a angry face, or even a creepy one. I just wanted one of Guts being Guts during the golden age arc. I found a picture of him with Griffeth, but I cropped Griffeth out, just leaving me with Guts.
