Bipalium Dragon sketch

Omnivorous reptiles. After being symbiotic, the biological character will change and become very irritable. Flapping the wings produced by the symbionts attack and tear apart other creatures from high places (they can't really fly). Compared with pterosaurs and birds, the impact of its huge weight is fatal to most animals. Scientists found only 30% animal matter in its stomach, and the rest were plants. All these creatures have a strong osteophagia. They often sleep on animal carcasses and chew fresh bones.

Wing Bipalium: one of the largest invertebrates known. After finding a symbiotic host, it will lose its aggression and penetrate its skin and nerve connections. Wing Bipaliums can fast for months, expand into wings when necessary. When the host sleeps, it will throw out the gastric sac and dissolve and digest proteins and minerals nearby. If the host is attacked secretly, the nerve connection will make it rush to the painful position to fight back. The nerve effect also makes the planarians rush to the joints and fragile bones when the host is excited, so as to prevent the host from being injured when landing.
