Eatle

He is a robotic humanoid alien with a beetle-like horn and a big metal. Eatle has sharp fingers and enhanced strength, allowing him to rip though material and eat inorganic material such as rocks to convert into powerful laser breams that he shoots from the slot on his horn. He briefly made his debut in "A Knight to Remember" on a short failure attempt to fight Vilgax, with his full ability revealed in "The Enemy Of My Frenemy". Then, he appears in "Catch a Falling Star". Ben uses Eatle to fight Julie in "Night of the Living Nightmare". Ben uses Eatle in "The Ultimate Enemy Part 1" to fight with George against Vilgax. He may be currently be one of Ben's favorite aliens along with Fasttrack as they have been used the most in season 3 of Ben 10: UIltimate Alien.

Eatle returns in Ben 10: Omniverse shown at Toy Fair. All though he has the same coloring scheme, his body is made more beetle-like in body shape with his Omnitrix on his stomach.
