To start this off, this is nonsense and totally just for fun! Here’s my idea prompt: You can fuse 3 dinos right off the bat into a Unique straight to L21, then add 1 more Dino to it at L25 that makes a Paragon Rarity L26.
So for example:
Unique rarity Pterogtherium
Pterogtherium+Concavenator= Paragon Rarity Venatrascendon
So what can you come up with?
