Grizner is large brown bear.
Gundham somehow managed to bring a live brown bear to class, apparently to demonstrate his talent with animals by performing a series of strange gestures with the animal. When the bear eventually bit Kazuichi and Teruteru's hands (which were holding a donut and a banana, respectively), Gundham claimed it was karmic retribution for the duo's off-color suggestions about Mikan Tsumiki and the Ultimate Imposter's absence.
During morning class in Nagito's imaginary world, Grizner is fed a large piece of meat from Teruteru's skewer.
