Druman (Japanese version Keble (キーブル,Kīburu)) is a Pyrus and Darkus hybrid Bakugan. His body is a little bit more Pyrus than Darkus and his wings are more Darkus than Pyrus. He has hands with eyes on them for wings and a reptilian body.
Druman and Centorrior are first seen in the joint Pyrus-Darkus world when they chased away an army of DarkusGargonoids from Dan and Drago, revealing shortly after that the only reason the did what they did was so they could fight him themselves. Nova Lion wisks them away before the fight can begin, but Centorrior and Druman found them anyway and started the fight again. The second time Centorrior is able to fatally wound Nova Lion and once again Dan and Drago flee. When Dan and Drago are found they fight for another time, with both of them captured this time so they could not run. After they receive some back up in the form of Masquerade and Alpha Hydranoid they and an army of Darkus Gargonoids and PyrusSerpenoids were defeated due to Masquerade's plan, using Drago as a decoy and Hydranoid as a long-range attacker.
Later, he, along with Naga's other servants, go to Earth and attack. Some earth children try to fight him and at first gain the upper hand, but Naga helps all the hybrids win their battles.
After the other four hybrids are defeated, he and Centorrior fight the Brawlers. Although he puts up a good fight, he is eventually destroyed.
He usually uses abilities that either weaken his opponent or reflect his opponent's attack.
