There's really not much to say. Spinoraptor, Stegoceratops, Ankylodocus, and Spinoceratops. I can throw in some ideas for extras, but these four are really the only ones needed, and would fit a DLC since they usually have four species each.
Ideas for extras (All use genomes from base game creatures only):
Those are the only ideas I can think of for extra types of hybrids, but I honestly think the four mentioned at the start would be enough for a hybrid DLC.
Ideas for extras (All use genomes from base game creatures only):
- Hybrid A: Iguanodon + Nodosaurus - Large ornithopod hybrid with a bulky body and thick osteoderms - Relatively docile for a hybrid, but still pretty mean
- Hybrid B: Liopleurodon + Deinonychus - Medium marine hybrid with amphibian features
- Hybrid C: Parasaurolophus + Compsognathus - Mini-Parasaur!?!?
- Hybrid D: Dimorphodon + Troodon - Nightmarish nocturnal pterosaur hybrid with two rows of teeth, bat-like wings, and glowing eyes
- Hybrid E: Gallimimus + Proceratosaurus - Mildly creepy omnivorous hybrid with a slender body and a coat of feathers
- Hybrid F: Stygimoloch + Baryonyx - Extremely ugly omnivorous hybrid that looks like a potato that got hit by a semi truck
Those are the only ideas I can think of for extra types of hybrids, but I honestly think the four mentioned at the start would be enough for a hybrid DLC.
