I'm afraid I'm not well versed in Zelda lore. Link is a pop culture character. To be honest I don't know much about his character, but I do know who he and the LOTR character Legolas were based off of.
It is indeed! I write an AU where Wendy and Robbie never broke up. He's more of an emo and isn't a bully. Dipper is in love with Wendy, but has feelings for Robbie as well which he strongly reciprocates. I absolutely love angst especially when it comes to romance.
