Razor Claw

From Alien Species

Another large breed with a purple coloration and large, sharp claws on its fingers. It is known for its great speed, making it hard to defeat or even keep up with. It is fond of using that speed to make dashing attacks in which it uses its namesakes to cause massive damage and slice its victims in half. The birth of the Razor Claws was a result of a genetic malfunction in the cocoon process.
