Thunderball

During the Storm of Chaos, the giant Thunderball was the loader for the enormous cannon known as Ulric's Thunder, part of the defences of Middenheim.

Sadly, Skaven infiltrators saw Thunderball as an easy target and used warpstone to mutate his body into a writhing mass of tentacles. The monstrosity rampaged through the streets until it was killed by Count Valmir von Raukov's Dragon Bow
