8901 Hakann is a BIONICLEset released in early 2006. The set includes the Piraka known as Hakann.
He was once part of the Dark Hunters organization. He is a master of double and triple-crossing his fellows and is known as "The Bully". Pressing hard on the rubber piece on his launcher will launch a sphere.
Enemies of Hakann never know just how he will defeat them - with heat vision, lava launcher, or devastating mental blasts. Hated by the other Piraka for his constant scheming, Hakann plans to eliminate them all and steal the Mask of Light for himself.
