Bart was shock; he couldn't believe his eyes. It never occur to him the consequences of his time travel would be this bad. But he had been wrong. Very wrong.

It had all began a few hours ago in Bart's history class. They had been studying the prehistoric eras, and had to do a project on these times. Not a problem, unless you were Bart, whom's attention span lasted for about thirty seconds before something else came into his head.

The day ended. Back home, he quickly changed into his Impulse costume and zoomed out. But a millisecond before he reached the door, Max stopped him. "Where do you think you're going Bart?" he asked in a serious tone.

"Uh, out to save the world?" Bart tried to get away from Max, but his grip was too strong.

"Yeah, right. I saw your homework on the table, and I want you to start it right away."

"Fine, O.K, I'll start it right away,"

Max let go of Bart, and he started to climb the stairs, but then vibrated through a nearby wall and got outside. "Bart, come back here right now," Max shouted, but Bart was travelling at top speed. Max realized he had no idea of where he was going, so gave up trying to get him back.

Bart didn't know where he was going either, so he just ran around Manchester looking to see if anything was happening. Nothing was, so he ran to the Young Justice cave instead. Hardly anyone was there except for Red Tornado and Robin.

"Rob! Red! Hey!" he shouted to them.

"Hello Impulse," said Red Tornado.

"Hey Bart. What's up?" Robin asked him.

"Nothing much. Anything wrong in the world?"

"Well, nothing much for us. The Justice League's on something big, and..."

Robin was interrupted by snoring. "Bart, wake up!" he shouted next to Bart's ear.

"WHOA! Sorry man, but that was sort of boring."

"I only said 12 words!"

"Exactly." Robin sighed, and went over to the cave entrance. "Hey Robin, I gotta ask ya something!" Bart shouted to him.

"What?" Robin called back.

"Will you help me with my homework?" Bart said hopefully.

"Do your own homework," came the response.

Bart sighed. He had to find a way to do his project on time. If only he had been listening or...hey, was that a mushroom growing by the computer?

Bart snapped out of it. He had to concentrate. Think, Bart, think. He got it. All he had to do was go through time back to prehistory, write some things down, and he would get a good grade for sure. It was a great idea. He'd done it before, he knew what to do.

Bart began to run. He started off at a normal speed for him, then faster, then faster, then faster and faster and faster andfasterandfasterandfasterandfasterandfasterandfasterandfasterandslowerandslower andslowerandslower and slower and slower and slower and slower until...Bam!

Bart landed in a pile of dirt on the ground. He brushed it off his costume and looked around. He could hardly see anything that interested him. If this was prehistory, where were the dinosaurs? He pulled out a piece of paper and a pen that he'd got to write down the stuff Robin might have told him if had bothered to help. He scribbled down 'Nothing of interest happened during this time'.

He put the paper away and was a bout to go back to the future (Yes, I know it's bad but give me a break!) when he tripped over a quite large reptile on the floor. "Stupid lizard," he muttered, and kicked it. It landed in a hole full of funny-looking liquid. Bart couldn't be bothered to think about what he'd just done, and speed off back to the present day for us.

Which brings us back to the beginning. Bart had got back and saw an amazing sight. All of the people had been turned into half-human half-reptile mutant thingies. He screamed, but regretted it. All of the mutants heard him, and went after him. Luckily though, it was just like the video game 'Lizards from the Planet Reptilion' (What a corny title), a game he had got the highest score on. He dodged the lizards, and decided to go back in time and stop himself from kicking the lizard (Now it's getting a bit complicated.)

He sped up again and ran back to the past (I'll skip the whole 'fasterandfaster' thing 'cos I can't be bothered to do it again) and was back in the past. He looked around and saw himself. He looked really handsome, he thought. But he then saw the lizard and got back to the matter at hand. He zoomed over and picked up the lizard before it got in his way.

He had done it. He had saved the world from himself. Bart had stopped Bart. Wait. Did this mean he was a hero or a villain? He didn't think about it and ran home. He would have to use a...shudder...book to do his project. Oh well.

The End. Thank you for reading.
