Orcanoch was released as part of the Microverse line, Hasbro’s miniatures line meant to compete with Galoob’s “Micro Machines” (before Hasbro’s purchase of Galoob). It transforms from an orca into a multi-level tower base. Its pectoral fins pull out to reveal a separate one-robot mini-sub. The orca head is removed (and presumably set aside) to reveal a control tower with spring-loaded missile launcher.
Orchanoch's box-art shows a presumed Maximal that cannot be identified as an existing toy or character. It kind of sort of looks like a cross between Armordillo and Snapper, but isn't either of them.
