[[Image:Mon-siegebreaker-decapitation.jpg|thumb|300px|left|Siegebreaker biting off a Barbarian's head.]] Besides his gargantuan size and speed, the most talked about feature of Siegebreaker's appearance in the WWI 2008 gameplay movie were the fatalities he delivered to two of the four characters fighting him. The most memorable was the death of a barbarian, when Siegebreaker picked up the hero and outright bit his head off, then threw down the decapitated corpse with a howl of rage. In result of this action, Siegebreaker's jaw was covered with blood and body parts until the end of the battle. A Witch Doctor was similarly destroyed, not by a bite, but by a spike to the ground, after being picked up and howled at.

That conclusion just begs another question, though. How many such special animations are there? Do all the bosses have some special fatality move they only show when they kill a character in a special way? Do any regular monsters have such talents? Do players die in as wide a variety of ways as monsters? Shattering when frozen, falling down and burning to a cinder from flame, charring to a skeleton from lightning, etc? Hardcore players might want to try out some softcore, just to run around and die in interesting ways.

Another interesting trick of Siegebreaker's is his death animation. He [[:Image:Mon-siegebreaker-corpse1.jpg|crumbles down to pieces]] in a very pretty way, like a decaying, hollowed volcano, but then sends out five jets of red light, which swirl around the screen for a moment before crashing to earth. Where the lights land, in the cemetery where the battle took place, great numbers of skeletons spawn. It's not clear why a giant centaur-dog beast like Siegebreaker would spawn human skeletons when he dies, but it is certainly a cool effect.
