This replication of a Hatzegopteryx is a scrapped idea of a robot meant to kill off drones, and specially... Disassembly drones. It has a strong beak with sharp metal teeth like spikes on the outer upper beak. Their large legs overlap their giant wings that are equipped with gigantic claws to balance flight diving and stab into its target. It's large crested head is meant to pick up sounds from afar and signal others nearby by sending out a sonar signal of sorts ?

To unfold it's strangely positioned wings it jumps up and flings out it's wings, unlike the actual dinosaur its wings are overlapped by it's legs to keep more steady movement, but it's wonky so it prefers to fly. It has weapons itself though, large missiles on the underside of its wings, two on each.

These are the only weapons they have, and probably for a good reason.

And if wondered, yeah, they roar like a trumpet 😭
