Ty just looked at the bulk that filled out the clothing of the man standing next to him. The guy was in perfect shape and looked like it took a lot of hard work to chisel out all of his features. The lines in his face were put there to make him handsome and they did the job well. What made Ty react in terror was the mark on the massive man's chin. It matched the one on his chin that he got as a baby when he fell out of his high chair on a piece of glass.
"Yes Ty, I am you from the distant future and I don't have much time to explain what I am doing here before it happens again. You have to stop fooling around with the lives of other people. There are many forces of the universe that we don't know about and somehow we got one but abused it. You're just a nerdy kid now so it's cute but you will grow to be me and the bit gets old fast. I can't make you stop. I can only ask. If you show that you can handle the power with responsibility, the time loop will be broken. If not, you will see me again."
Ty blinked his eyes and woke up in bed from a sound sleep. "Oh hell, it was only a dream." He heard the sound of a rock hitting his bedroom window and the little kid next door was yelling his name. Ty smiled and added 250lbs of muscle to him.
"OH SHIT"
