This motorcycle was terrorizing the Digital World before Beelzebumon be its owner. A Tsuchidarumon village was beset by this motorcycle. When Guilmon decided to drive that motorcycle, a Choromon appeared, saying that it was a possessed driver before Guilmon. Choromon also told that Behemoth controls its driver. Leomon helped Guilmon to throw off the motorcycle, and, it suddenly fell. A short time later, Beelzebumon came, and Behemoth found his driver.
