Benton Dusk is a character that appears in Bakugan Battle Planet. He is on mission to protect the Bakugan from being used for evil and selfish purposes, unlike his sister Philomena Dusk, who is doing the opposite and wants to profit off Bakugan with her company AAAnimus Inc. He owns a Hydranoid.
A mysterious, enigmatic figure, Benton Dusk plays a pivotal role in the world of Bakugan. As a world-famous business magnate, investor, engineer and inventor, Dusk is truly a modern renaissance man. He is ranked as the 79th wealthiest person in the world and ranked 16th on Culture Magazine's list of the World's Most Influential People. The very existence of the Bakugan holds great interest for Dusk. For him, they fall right in line with how he sees the future of humanity. His goal is to keep Bakugan and their powers open source. In other words, available for all to use. To that end, Benton recruits Dan and the Awesome Ones to aid his personal quest to collect the Core Cells.
