Scorpinoid

The Scorpinoid is a gigantic, alien scorpion from Sectoid 1, he a lives in pit that is located under Lord Dregg's castle who is used to execute someone. Not only he is a weapon and a type of transportation for Lord Dregg, he is also the pet of the evil ruler.

The Evil of Dregg
The Scorpinoid first appeared after Lord Dregg threw Leo, Mikey, Casey, and Raph into his pit, where attacked them and tried to eat them, but the guys were able to escape from him, after April throws down a rope. Before the Turtles escaped from the pit, Leo pushed Armaggon into the pit where caught him with his claw and eats him before letting out a big belch. As the Turtles, April, Casey Fugitoid, Mona Lisa, and Sal Commander escape to the Ulixies, Scorpinoid is unleased and chases after them with Lord Dregg and a swarm from Vreen and Xxax Bees. During the battle that follows, the Scorpinoid is able to strike down Mona Lisa after she admitted her love for Raph, renewing his will to fight. Horrified at seeing Mona struck down, and now fueled with anger, fury, and grief, Raph is able to overpower Dregg and decapitate him, revealing a robot head underneath Dregg's normal one. After Raph takes down Dregg, Scorpinoid tries to attack him again, but is blasted with laser beam from the Ulixes and incapacitates the Scorpinoid before vaporizing the Vreen.
