Out of seemingly nowhere, a bright light swung towards Kray's neck/upper torso area, surprising the green beast. This light less loose an explosion, most of the attack hitting its intended target, but not in the entirely intended place. Kray had just begun to rise from his stoop out from under the doorway, elivating his upper body. This caused the blast to hit him in the chest(doing signnificantly less damage than it would have in the collarbone area), sending him flying backwards back into the room and through several walls. One. Two. Three. Stop. 

Kray layed against a wall several dozen feet from where he previously was. He had massive burns and scars all across his chest area. Black splotches clouded his vision, making him feel tired. I need to sleep. No. Dont.
He slowly pushed himself up from his weakened position, and even under the effect of steroids, his enhanced need for violence was beat by his common sense to escape. He began to stumble down the hall to his left. Wait.

He turned, and his tatoos began to glow, and then they dulled all except one. The brick wall one. A wall appearing exactly the same as the others rose from the floor, covering Krays escape path to hide from his opponent. He then continued to stumble down the wide hall.
