Fan:Borenmon

Borenmon is a Cyborg Digimon whose name is derived from "Boren", which is Dutch for "Drill". Borenmon is significantly different from how Dorulumon was. Borenmon endlessly creates tunnels, sometimes interconnecting it's own tunnels in the process. It's right arm is equipped with the "Dyna Claw", which is designed for explosive attacks meant for destroying and shattering diamond to pieces. Being from an alternate universe from which Xros is rarely used for Digivolution, Borenmon's own existence may have never been known about in any other situation, and some call it merely a legend unless one actually witnesses Dorulumon digivolving into it, because Borenmon are incredibly hard to find in the wild.
