Abominations by science aside, have some autistic headcanons.
>Dracovish mostly lived in areas with a large amount of lakes, though weren't shy to living in the sea
>Their large frame mean that they can't swim freely in the water super well, but their highly developed legs allow for easy walking, dare I suggest straight up running almost, underwater.
>Their main method of attack would be to stand still and lie in wait before rushing forward in one large pounce with their legs, using their fins to steer slightly if needed. Their main aquatic prey would probably be miscellaneous fish, Omanyte, and Kabuto.
>Omastar shells are simply too hard to break for Dracovish, while Omanyte need a bit of force but are do-able. Kabutops are probably predators for Dracovish. Due to a Kabutops' ability to easily 1v1 a Dracovish without issues, Dracovish have adopted a small herd lifestyle consisting of roughly 5-10 individuals on average, though numbers as high as 20-30 are not unheard of. Through numbers, they're able to bring down a Kabutops if needed.
>Able to hold their breath for several minutes at a time, Dracovish are capable of walking on land, and actually running fairly fast. Dracovish are among the most consistent fast runners on Pre-historic Poke-earth, beaten out only by the likes of Tyrantrum and Dracozolt in short bursts.
>Though a Dracovish typically ventures above ground solely to retrieve miscellaneous bits of fruit, they aren't privy to attempts on live prey. Arctozolt are their main source of above-ground food due to their slow speed. The amount of voltage Arctozolt regularly put out isn't strong enough to deter most Dracovish unless it's consistently applied. Dracovish have adopted a strategy of rushing towards Arctozolt, jumping on it's sizeable torso and toppling it over, then repeatedly bashing its prey's head in with it's feet before feasting.
>In large, dedicated numbers however, Arctozolt have been able to keep Dracovish at bay with their ice affinity.
