I love kirby. He is so round and you just want to give him a hug. But I still love Link. First of all, he is the main person of the Legend of Zelda. Second, I love his tunic. He also had great facial expressions.
No rules allowed? Link wins due to heavy arsenal of weapons and range. If I'm not mistaken, Kirby is a close ranged fighter with no abilities. No rules is no rules.
Link, with all his weapons that can be used for long distance combat between someone who has to get close in order to suck you up and copy one move? Game over.
This is a hard decision, but I love both of them. Imagine Link wearing a pink tunic in honor of Kirby? I would love to see that! XD Nintendo should make a cross-over of Link and Kirby! I would so buy that game!
