Krowll (Japanese version: Cryskull, クリスカル) is a spider-like Bakugan in Bakugan: Mechtanium Surge. It was one of Sellon's Bakugan, but was used by Soon and Anubias at different periods of time. Its BakuNano was Slicerix.
Looming ominously over adversaries in battle, Krowll's appearance strikes fear even before he begins to attack. Krowll can fire a shock wave to blow opponents off the battlefield.
In A Royale Pain, Krowll is partnered up with Soon to participate in the Bakugan Battle Royale. Krowll also uses its BakuNano Slicerix against Robin and some other brawlers. Krowll then tried to fend off Silent Strike, when Shun had summoned it, although it lost with Bolcanon due to the barrier protecting Silent Strike.
In True Colours, Krowll battled against Taylean alongside Spyron and Vertexx, but was easily defeated.
In Unfinished Business, it appeared again under the use of Anubias. Both Dan and Drago were wondering why he had Krowll since it was not used by him before. Anubias then made him combine with Krakenoid to form Mutant Krakenoid and later Mutant Krowll.
