Disney Vs Non-Disney Villains War
The Guards of King William are briefly featured as part of Frollo's French army, in the early events of the first war. After learning of Rothbart's recent acting of witchcraft, Frollo orders his troops to seize him at once, while they also destroy many fragile and valuable objects of the sorcerer, in the process. However, they do not have the opportunity to apprehend Rothbart, as he breaks himself from the guards and challenges the evil judge, by transforming into his wyvern form, the Great Animal. In a flash, Rothbart grabs Frollo and topples him from a higher height. The Guards of King William do not respawn for the rest of the war.
