Hiro and Wilbur are a lot like Hiccup and Jack Frost. The bad boy and the nerd finding one another. Wilbur is a time traveling, arrogant dork, while Hiro is an arrogant superhero nerd. Both really compliment each other well. They would have a love-hate thing when they first meet but soon get over that. When Hiro is down (being the more pessimistic) Wilbur the optimistic one who can cheer him up and tell him to keep going.
