Tarrasque

Thought Chimeras were bad? try their top league hybrid children... like this one.

Tarrasque are born chimera and dragon turtle pairings, which are incredibly rare themselves. They resemble chimeras except for the fact they only have the lioness traits that carry over along with the dragon turtle horns, webbed hands/feet, and shell along with the steam breathe weapon that's now laced with the snakes toxins to make a toxic steam attack. Their tails are now more akin to an actual turtles with some webbing on the end but that's fine since their saliva is full of aphrodisiac toxins used in their steam attack. Despite the large protective shell, they're quite fast on both land and sea.

Tarrasque are able to travel greater distances thanks to being both aquatic and terrain based monsters. They also carry over both of their parents strength fueled by the chimera's challenge hungry nature and dragon turtle's greed. Their natural affinity for water and water-based magic certainly makes them a larger threat.

Tarrasque raised by dragon turtles grow up to be treasure hoarding deep sea divers that occasionally come to land to see what's available. Chimera raised tarrasque wander great distances in their endless search for bitches. All tarrasque have a fondness for pillaging monster settlements and fucking their warriors for several days at a time alongside shipwrecking.

Their weakness lies in the rare moments they travel through areas like deserts or cold climates. Some tarrasque get too bold and venture in places not suited for them, making them easier targets for monsters to fuck over. It can also be harder for the younger ones to get back up when knocked on their backs on land.
