a giant half-dinosaur half-shark, which could transform between shark-head dino-body and dino-head shark-body for sea to land transition. Although, I seem to have overlooked the general automotive theme. Perhaps it's because I just finished watching the movie Dinoshark.
(Not recommended, by the way. Neither is Sharktopus. But if you do want to watch a terrible shark movie, I suggest Mega Shark vs Giant Octopus. It's really bad/great.)
