Murderous teleporter

The door slid open and two men rushed in, their eyes clashing with Derek's as they saw the corpse of their comrade. 

Derek quickly identified those tattoos. 'Shield guards' he mused internally, while watching both men, Derek folded his sleeve up to his elbow.

He could see the distorted faces of both men when they saw their comrade clawed to death. With unrestrained rage, they both rushed toward him, but they had missed something.

Who owned those claws? They had looked round but nothing here could match those claw wounds, that was because Daniel reduced to his small form and hid. When the two men faced Derek, he revealed himself.

"GRRR" With a reverberating growl, Daniel sunk his fangs into the first man's neck and shook his head, tearing the soft flesh as the man's windpipe was torn apart in seconds.
