Organization- Dragonbat Fire Breath

The thing unfurled its leathery wings and turned its head around on a long neck to look their way. A huge bat, with an almost childlike face… a small dragon, with smoke curling from one nostril… she guessed it really didn’t matter which.

The dragonbat growled fire.
...

Dana couldn’t help looking back, and she saw the dragonbat winging at them from the guard’s station, fire gushing from its mouth and clawed wings ripping at the air.

They took the corner at speed, running straight into a man in a long white lab smock and with a terrible cut to his scalp. He glared at them but didn’t seem to see, and as he pushed past them the dragonbat struck him in the chest.

The impact was immense. It powered him against the opposite wall, cracking plaster and splintering wooden studs, casting them both through to the space hidden beyond. The fracture was illuminated by a burst of flame, and the man’s screams quickly boiled away. The dragonbat rocketed from the hole again, meat and stringy stuff hanging from its mouth. Marty leaned across Dana to protect her and raised the gun, but the creature ricocheted from the walls and disappeared down the corridor, leaving scorch-marks wherever it touched.

They stood, and Dana couldn’t help herself; she took three steps to the hole in the wall and looked inside.

The man lay dead beyond the fracture, a cauterized hole in his stomach where his guts had once resided, hands curled in like dead spiders. His mouth was open in a silent scream, and smoke drifted up past his shattered teeth.
