Out of all the leaks, the only new figures outside of "exclusive" versions that Mattel haven't showed off were the following:
>Tri-Clops, Stinkor, Webstor, Fisto, Moss Man, Jitsu, Buzz Off, and FakerSeveral of these characters appear in art for Wave 3, including Tri-Clops, Stinkor, Faker, and Fisto. Faker is also shown driving a Roton. Mattel has also said multiple times that the characters featured in the art, isn't a coincidence, that they're deliberate, and strongly suggested that these were characters and probably vehicles, such as the Rotan that would be appearing in the line.
