Nightscream

Nightscream is a Maximal who is one of the heroes from Beast Machines Transformers.

Background
When armies of Vehicons conquered Cybertron, young Nightscream survived alone in the darkness below the surface of the planet. This trauma influences much of his behavior. He's always on the defensive. Paranoid. Rude. Distrusting. Confrontational. But really, he's just a troubled kid, and he's been through a lot. Inside, he's got a good heart. He's just got to learn to stop fighting friends and enemies alike.
