Marcus grinned as he watched the charging beast, he set himself up into a classic defensive pose, almost like he planned to hug the thing. Marcus watches as it charges, the rush of the hunt pouring yhrough his veins. The faces of those he'd slain flashed before him and in his mind numbers calculated themselves rapidly, configuring to the charging beasts run.
He'd wait for it to near before grasping one of its appendages and using it to twist about the creature, he'd deliver a sharp elbow to the rear cranium as he passed before tearing the still clutched appendage from its socket, It would be in pain and likely lash around to face him, he would need to go under the swing before jamming the appendage upwards and hopefully past the ribs and inyo the heart. Easy.
As it neared he finished his plan mentally. This little beasty was about to be put down.
