Basilisk

The basilisk is a large, snake-like abnormal.

History
It has scaly skin and two wings attached behind its head that do not, however, enable it to fly. It spits acid and can breathe fire. When attacking, it scans for faces, especially eyes. This means looking at a basilisk is fatal. It's completely deaf, but has a strong sense of smell. They used to roam the surface, but disappeared a long time ago when they relocated to Hollow Earth.

Dr. Helen Magnus and Dr. Will Zimmerman came across a basilisk shortly after entering Hollow Earth. They were saved by Birot and Linor, who distracted it with a hologram.

There is a basilisk feeding ground below the Indonesian caldera.
