GiGi Armlet (ギギの腕輪 Gigi no Udewa) is a mysterious O-Part of the Incas that was created 120 years ago as one of two keys (the other being the GaGa Armlet) that would allow the user of the two to rule the world with Incan super science. The GiGi Armlet serves as Amazon's power source along with being the only thing keeping him alive. Grafted unto his left arm, Daisuke is originally unaware of the Armlet's true power until he found the Quipu that revealed it.
