Hero Creator is a game on Hero Factory.com
Just as the title would suggest you are allowed to create a hero of your own with any colors of your choice, but limited to the armor of the heroes in the Hero Factory TV Show.
After you finish picking out your hero's weaponry you can choose which class he or she is in. Your choices are between being a Fighter, a Technician, or a Gunner. These classes are then used in the game, on the same website, known as Mission: Von Nebula. This video game will allow you to play as your character and destroy Von Nebula's henchmen while you progress.
Though there are serious limitations in the Hero Creator, it is a nice connection to the online game.
