First he was a necromancer in human form, then he was trapped in the Book of Monsters and now he is a cloud. Monstrox is the most evil… uhm… vapor? But even in the form of a cloud, Monstrox is still very powerful. His lightning can turn good people evil and animate stone statues to obey his every twisted command. He has given up on taking over Knighton, now he is out for full-on destruction, of course mixed with his usual humorous insults. You think you have seen bad weather? Then check out this dark cloud!
