The Tyrannodrones are the minor antagonists that appeared in Power Rangers: Dino Thunder. They are a race of dinosauric humanoids, created by Anton Mercer and Tommy Oliver, as a mixture of dinosaur DNA and technology. When Mercer became Mesogog, they were reprogrammed to serve him. They used invisiportals to get around and are assumed to be destroyed by the end of Dino Thunder. They look like the Stingwingers
The Tyrannodrones also appeared in the Dino Thunder/SPD team up episode, Wormhole, along with Zeltrax.
The Tyrannodrones were the first Foot Soldiers created by a specific ranger which were used against the Power Rangers of the day. Ironically, that ranger was Tommy, the first evil Ranger and a member of the team that fought them.
