D&D 5E Need Monster hybrid ideas, please help

[atanakar]

I'm very fond of the Giant Spider-Dragon hybrid in the Creature Codex by Green Ronin. I'm trying to place it some where in my current campaign. It's very ugly and dangerous with its venom spit and cone attacks. Love it!

Hydra + Rust Monster.
Troll + anything immune to fire and acid.
Invisible stalker + chasme.
Intellect devourer + shadow.

I would be tempted with an Island of Dr. Moreau thing. Maybe cross an orc with a bear or an orc with a lion. A few of these exotic animals with local humanoids could make a BBEG more than just a madman.

Reverse Centaur and Reverse Merfolk, just to mess with the players.

Hi, sorry about the long silence. With everything going on d&d kinda got put on hold.
But something I want to clarify my BBEG is not a mad scientist, he's eccentric but he mainly wants to find a way to make the ultimate creatures. So his goal is to take creatures and make what makes them strong, stronger and make their weaknesses less realavent. It's not about making monsters, it's about chasing perfection and primal purity.

The kracken is primal storms. The elder brain is pure psychic power, but requires brine to live. Both have tentacles. The blue dragon is aligned with lightning hence the connection to the kracken, the black dragon lives in swamps and filthy, stagnant water hence the connection to the elder brain, both dragons are dragons, so he combined them all to make a more pure, stronger creature. That is his thought process, not "making monsters".
