This is one of the Illustrations appearing in the recent "RIFTS: Black Market" published by Palladiumbooks. [link]
The robot steed is manufactured by Bandito Arms and the steed is an amphibious unit combining a shark with a stallion. It has built in cannons in the nasal cavity and can utilize its tail fro melee combat along with its hooves. The underbelly has vector thrusters for assisting it underwater and leaping. In this illustration I chose to have it being piloted by a Rifts dimensional being known as a Loak.
