If I had one superpower...

     A tall, skinny man with short, black hair named Jeff was in his room casually, until suddenly he accidently knocked his lava lamp over and broke it. He wanted a new one, so he decided to go no buy a new lamp.
     He found a store selling all kinds of lamps, he went to the lava lamp aisle. He noticed a nice looking lava lamp, so he bought it. Later, at his house he unwrapped his new lamp with great delight. The lamp was smudged all over, so he rubbed it against his long sleeve. A green goblin appeared next to his feet, barely taller than the new lamp.
     "Thanks for cleaning my house, I've been meaning to do that." the goblin said in a high-pitched voice
     "Oh, I didn't-"
     "I'll give you one superpower, of choice, for your kind act" the goblin rudely interrupting. Without thinking Jeff wished for invincibility, and he got what he wished for. He didn't feel much different, so he grabbed a conveniently placed heavy brick and dropped it on his foot. It broke easily, the brick did.
     The same day Jeff made his own superhero name, 'Invinci-Jeff' and was ready to fight crime. He never really fought crime or stopped any super villains as he had hoped to, but he did like the aspect of not being harmed in any way. What he didn't realize was, being invincible also means you are immortal, so he lived on and on for ages.
     It was four-hundred years since the day Jeff became invincible and all of his family and friends he knew were all long gone, and this made him sad, very sad.
     Jeff went to as many lamp stores as he could find and rubbed as many plasma-lamps (lava-lamps had long since gone out of style) as he could. Finally he found a smudged dirty plasma lamp and rubbed it vigorously. Out came a blue ghost.
     "Thank you for cleaning my-" the ghost started
     "Yea, yea, I wish I had the ability change and travel time." Jeff hurried
     "Fine then, take your power and begone!" Jeff was soon having fun again as he was traveling through time, both future and past. Jeff was having fun and all but then he thought about his friends and family, and had a brilliant plan. He concentrated hard and traveled to when the goblin offered him a wish. Future Jeff grabbed the lamp and smashed it against the nearest wall, as both the lamp and the goblin shattered into a million pieces.
     "What are you doing?!" past Jeff said in anger
     "Let me explain all this..." so the future Jeff had to explain all this to his past self as quickly as he could. The two Jeffs didn't know much about time traveling, but they had created a paradox with there being more than one of the exact same being in a universe. This paradox caused a black hole that sucked up both Jeffs.
     Jeff was still invincible so he had survived the suction of the black hole. It was strange here, nothing was there, and yet at the same time, everything was there...somehow. He felt uncomfortable here, so he tried time travel both past and future, but everywhere he went, there was another Jeff, and that meant paradox, which meant another black hole. Time travel is confusing.
     After what seemed like weeks, Jeff gave up at last but he had done something incredible while doing his paradoxing or whatever. He had managed to create millions of other invincible Jeffs with him. He decided to live them for the rest of his life, which lasted literally forever, and he was happy, at last.
