He encountered Boltmon at Ueno Park on Valentines's Day, in the guise of a strange figure with weird hair. He was the one who talked Boltmon into causing the chaos at Ginza. In order for ALL the Digidestined of Tokyo to be in one place so he could destroy them personally. To increase his chances, he brought a Control Spire with him to hinder any Digivolution, except Armor Digivolution. After a mixed-up of D-Terminals, Pukumon was sent running after the beating he took from Saggitarimon, Pteramon, Butterflymon, Manbomon, Rinkmon, and Pucchiemon.
