Rhinosaurus

The Rhinosaurus is a mechanical rhinoceros created by Willem Viceroy. It serves as the primary antagonist in the episode "McFear Factor".

Role in the episode
The Rhinosaurus was created to turn one's greatest fears against them as part of the plan to capture the Ninja. Its horn is an emotional sensor which can detect one's greatest fear. Once it zaps a victim with its horn, its back end produces a gas which forms a phobioid (an embodiment of one's fears).
