Franchise: Disgaea

The design of the cyborg character Kurtis is an homage to 002 Jet Link, one of the protagonists of the famed anime and manga series Cyborg 009. Starting with Disgaea 2: Cursed Memories, players could acquire a recurring item in the series associated with Kurtis called the Accelerator. Purportedly equipped to a character's teeth, this item increases a character's movement range and can "approach the speed of light". This is a reference to the titular 009 Joe Shimamura, who could reach extremely high speeds by pressing a button hidden in one of his teeth.
