Background
Krogg, once the bodyguard of Colonel Arcticfox, was killed during an exchange while at a ranger election. His death was left as it was, though the USMC was known to have attempted to clone him for their own research and other purposes.
The Incident
Krogg, tampered and mutated into a hideous lizard-humanoid being, rebelled from his captors. During this escape, it was unknown as to how he managed to flee the complex. Following this escape, a hunt for him began, though it inevitably ended up in failure.
The cloned Krogg proved to be different from the original Krogg, though he was known to have appeared at the Ranger Center and requested the body of the original for unknown purposes. This clone remains on the loose.
