In Slender Fortress Edit
Jack is a Giant Teleporter in boss pack 4, he is a giant clown in a box, as called as JackintheBox, he is a teleporter and half chaser boss type, his main threat is to kill his victims using the power of statics, and somehow, This boss is a remake of Slenderman, exept that he doesnt kill on touch and he has a slower rate kill on statics than Slenderman, He creates Shock-Wave on Idle, making it easy to see where you are hiding at, but beware of making him chases you in hallways, as he uses statics, not pumping you to death!
