Denny is a secondary antagonist in Beyblade: V-Force, who was enlisted as part of Team Psykick's Harasment Team. He was used as part of a plot to gather data on the Bladebreakers, in order to steal their Bit-Beasts. His beyblade is Klarken which he owns two of.
Denny was an underground beyblader who was scouted for the Harassment Team, by Doctor K; he was one of many given a specially modeled kit, and ancient bitbeast, extracted from the Saint Shields' rock. Due to Denny's particular talents, he was chosen to wield Klarken , and two identical beyblades, wherein he would use Klarken's illusory duplicates to appear to use multiple bitbeasts.
Denny was then sent to challenge the Bladebreakers, and gather information for his employers; he would ultimately be defeated by Ray and Zeo, who would tag-team against his twin beyblades, and destroy his bitchip, releasing his bitbeast.
