The Pulse is a light-up looping/2A yo-yo in the Hardcore series first released by Duncan at the 2007 Worlds. It was initially available exclusively at the Discovery Channel Store, until it began to be distributed at other retailers. It is based on the Orb in terms of having that distinctive ridged body shape and a battery-powered light-up mechanism, but with Friction Sticker response instead of starbursts. If the user wants, he or she can equip the Pulse with purpose-made Looping Stickers. Also distributed exclusively in Hong Kong Disneyland is a Halloween Mickey Mouse edition of the yo-yo.
