Shrewmanoid

A lumberjack in the Pacific Northwest.  After seeing some strange lights in the woods, he tracked them down to a cave.  He went to find out what the source was and the cave floor collapsed.  He found a strange device that contained a portal.  Standing outside the portal was a bunch of woodland creatures staring at him as if they wanted him to enter.  He felt the urge to press a button on a control panel and was bathed in a strange energy.  He was re-made into…the Shrewmanoid.  The animals outside were now at his command.
