Sorry for taking so long, Mammal_Mage. Here's my latest:
Villain Name: Mister Mysterious
Abilities/Equipment: Brilliant gadgeteer; Meticulous planner; Reasonably skilled athlete/hand-to-hand combatant; Outfit is equipped with a variety of gadgets, including holographic projectors, high-powered lasers, a device in his helmet that allows him to control anything in the immediate are with electronics in it (his helmet is also designed to allow him to see out without anybody else seeing IN), a multi-purpose gas dispenser (which includes, sleeping gas, laughing gas, tear gas, stink gas, freeze gas, incendiary gas and even a gas capable of temporarily nullifying Commander Arthropod or Arthro-Pooch's super-powers); A considerable number of powerful robot minions.
Origin: A former stuntman turned super-criminal, Mister Mysterious is particularly fond of incredibly theatric approaches to his schemes and employing dangerously modified variations of Hollywood special effects as personal weapons. He started out trying to frame Commander Arthropod for a crime spree and then attack the super-hero under the pretense of being a new super-hero trying to bring him to justice. The scheme ultimately fell through, but the villain has eventually proven one of Commander Arthropod's most devious and persistent enemies.
Personality: Devious, greedy and single minded but tends to favor elaborate, multi-layered schemes.
Based on: Mysterio
Pet's Name: Copperfield
Species: Ferret (male)
Abilities/Equipment: Extremely limber (even by feret standards); Exceptionally skilled figher; Collar sprays out four different types of gases depending one side is pressed (The button front side sprays out a powerful hallucinogen. The button on the left sprays out sleeping gas. The button on the right sprays out freeze gas. The button on the back unleashes a gas that can negate Commander Arthropod or Webbly's super-powers for up to an hour).
Background: Figuring Commander Arthropod would have at least Arthro-Pooch for back-up, Mister Mysterious was pleasantly surprised to find a curious ferret who was extremely interested in trying to get food from him. Seeing how quick and agile this ferret was, the villain figured the ferret could be very useful with the right training. Thus, Mister Mysterious carefully trained the ferret and equipped him with a gas color; dubbing him "Copperfield" after the famous magician.
Personality: Greedy, nasty and sneaky.
Physical Description: Much like a regular ferret except for his silver collar.
