Lupus Gigantormus is a massive, violent wolf that prowled the area surrounding the castle of the Black Baron in Flight of Fancy of Sly 3: Honor Among Thieves.
Description
It was very violent, attacking anyone it caught sight of in its territory. Bentley was forced to overwhelm it using sleep darts enhanced with skunk balm. Once it was out, the Guru possessed it to attack the Black Baron's forces, thus ensuring fewer airplane pilots for the final round of the ACES Competition.
Lupus Gigantormus is very similar to Grizzle Face, a Canadian grizzly bear from Sly 2: Band of Thieves who prowled Jean Bison's lumber camp, but the difference between them is that Grizzle Face will not attack on sight, and Lupus Gigantormus will. The only way the wolf can be killed is by luring it into the river.
