Treblor

Treblor, also known as "Buzzard", worked as an agent of the Zombarian Retrieval Department, and initially allied himself with Agents J and K to hunt down the interstellar criminal Z-Ron. However, when certain revelations were made, Treblor turned against the MiB agents. He has reappeared on Earth since then, now in his true character as a bounty hunter and mercenary.
