She's lean, she's clean, she's an old school Autobot, she's Hydromeda!
About this creation
Based on set 5912 - Mike's Swamp Boat - here's the comparison shot.
Hydromeda and her friend Mike patrol the waters of the Dino Island chain, ever-searching for Decepticons.
A foothill shot, the pair are joined my Hydromeda's "engine", Spinner.
Searching the desert where a reported sighting of a robot scorpion was seen.
Finally, it's "back" to the foothills.
Hmmm, an early Powermaster Autobot, perhaps, Hydromeda is another member of what I'm calling Old School Transformers. Her form is very close to set 5912 and fits with the theme. I may refine her design a bit, dunno yet.
