Reptosect

Double Face was jealous that Nefaria and Boulder Beetle was picked over his plan. He called upon a green lizard/mantis monster with black hair and big steel teeth known as Reptosect to assist him in battle. He can detach the blades on its back to throw them and use them as weapons. After Boulder Beetle's destruction, Reptosect stepped in with Double Face (who was wielding a War Saber). When Dex transformed into his Super Gold form, he broke Double Face's War Saber before destroying Reptosect with the Ecto-Ray. He fits the category of Double Face's unit.
