Catchphrase: The Doctor is In!
Battle Class: Quickshot
Element: Tech

No one is really quite sure what exactly Dr. Krankcase is a doctor of. But his technical engineering achievements are legendary. The secret to his success lies in his modified concoction of glowing green goo, which causes wooden objects to come to life and turn evil. His unique skill set makes him a valuable asset to the Doom Raiders, who have plenty of nefarious uses for evil wooden creatures. It is also commonly known that Dr. Krankcase served as an evil inspiration to Kaos once upon a time, who had figured out how to make his own wooden creatures, the Wilikin, come to life after reading about the doctor's exploits in the Minion Monthly Catalog. Kaos also respected Dr. K's interest in world domination, doom, and his well-documented love of pickles.

After being captured by the Trap Masters, Eon gave these Krankcase a choice – either go back to a newly reformed Cloudcracker Prison or become a Skylander Sensei, teaching a new generation of Imaginators his formidable battle skills as well as how to stay clear of a life of crime. The doctor accepted this deal but first had to prove themselves by helping to re-arrange all the books in the Academy's library, a task which took almost two years, testing every ounce of will he had. And his knowledge of the alphabet. Now he uses that newfound knowledge to train Imaginators on the A, B, Cs of shooting, as the master of the Quickshot Class.
