Beast Spirit of Ice
The Beast Spirit of Ice (氷のビーストスピリット Kōri no Bīsuto Supiritto) was created from Ancient Megatheriumon of the Warrior Ten. At some point, it was trapped into a game that fell into Nanomon's possession. He was unable to beat the game but Himi Tomoki aided him in doing it when he was holding their D-Scans. When he saw that Tomoki was one of the Legendary Chosen he gave him the Beast Spirit of Ice allowing him to spirit evolve into Blizzarmon.
(Note: Is called Spirit of Ice B in the TCG.)
