This is a picture of a Nordic looking dude who may or may not be Link's biological father. He probably is, I just never pictured Link Sr. as a pantless cigar smoker. I mean, not that there's anything wrong with that. Love you Grandpa!
Picture (WARNING: all other images on that site are verrrrry NSFW. Clicking any of the other tags on the page will take you to cartoon pictures that will get you fired, including a ton more Zelda-themed ones I didn't look at, I swear).
Thanks to Yopoleo, who I question how he found the picture in the first place. Suuuure you just stumbled across it searching Google!
