I'll try not to make this story too long, but no promises. Since Halloween's coming up, I figured I may as well write something to do with "Treehouse of horror". I'm not too good at humor, though, so it'll likely be kept to a minimum.

Future Springfield:

It seemed peaceful, but as we all know, looks are deceiving. Most of it was destroyed long ago, but the center still existed, protected by a glowing shield.

And this was what Jessica Lovejoy was in charge of protecting. She was hardly a good girl, as her numerous love affairs had proved, but she was not the troublemaker she was as a child. Their situation had forced them to mature. She flew around on her jet sled, making sure the numerous defenses they had around the city were working properly. If it was up to her, she'd have stayed her normal self, but this duty was thrust upon her by the townspeople. What remained of them at any rate.

Over the years, they had all grown accustomed to loss. Both her parents were still alive, although crippled, but she had lost friends, such as Sherri and Terri. Almost nobody in Springfield had not suffered a loss of a loved one; Jessica considered herself lucky, given the circumstances.

"Hey, Jessica, what's going on?" Ralph Wiggum asked, also on a jet sled. At the age of 15, he was diagnosed with a major speech impediment, and thanks to his dad pulling a few strings, managed to get the help we needed. "Boring as usual?"

"Maybe so, but it's got to be done." Jessica replied. "I'm amazed we've lasted as long as we have; thank God for professor Frink. By the way, you were supposed to be here an hour ago! Where were you?"

"Sorry, Jessica." Ralph apologized, bowing his head. "I was just visiting my father." She nodded in understanding. Jessica was the leader of the resistance, but knew how to be kind, another thing this situation had taught her. Chief Wiggum had died in the last attack 6 years ago, trying to give his son time to escape.

"Any luck persuading the army to help us? Hydroponics aren't going to keep us alive forever."

"I'm afraid not; they're still too scared to come here. I can understand that, but they're abandoning us! Stupid government, can't do anything right…" The rest of Ralph's tirade is better left unsaid.

"The public is starting to lose their fear, so some of our funding has been cut. Our forces are well-trained, but we need more money. I'll be talking with Mayor Kirk, but he won't give us any more." Out of the 40,000 people still alive in Springfield, over 200 had joined their defense forces.

"What about Smithers? He might be willing to help us, although I'd prefer that you go. His crush on me is a little creepy." Since Burns was killed in the beast's first rampage, Waylon Smithers inherited his money, and spent a good deal of it fixing the nuclear plant and financing their shield.

A siren went off, indicating the demon's return. People ran outside screaming, praying that their defenses would hold. Jessica and Ralph nodded grimly, knowing what they had to do. It wasn't long before red and green energy was unleashed in a frantic effort to break the shield.

"You can't escape me this time, Jessica!" The demon laughed. Jessica flew closer, against her better judgment, wanting to get a look at him. Since the last attack, he had grown more muscular, and obviously more powerful. Now he was over 6 feet tall and had adorned a dark cloak so that only his red eyes were visible. "I'll beat you to death with your own limbs!"

"I've heard that before, Bart; it's nothing new." Jessica replied, rolling her eyes. She saw the rest of their army ready for action, complete with artillery. She thought sadly at what had become of her old love interest. Bart was a troublemaker, and terrorized, but he was never this cruel. A tear escaped her eye as she remembered why he turned into this thing. "How did you escape hell, Bart? Kiss up to Satan?"

Bart laughed, more loudly than she ever heard. "Never, Jessica! I found a more permanent solution!" He levitated an object that she eventually realized was the devil's severed head. "Now I'm the demon king! This shield won't hold me this time, girl!" The explosions resumed, and Jessica noticed that their defense was starting to fluctuate. What if he was right and the shield did break?

The army raised their weapons, although they were terrified at the sight of him. Hopefully, the civilians were taking cover in the underground shelter. Bart stopped momentarily, and they breathed a sigh of relief. However, it quickly turned to horror as he unleashed a terrible sonic scream, forcing them to cover their ears and recoil at the sound.

Jessica did likewise, looking at the 15 shield towers. They were holding for the moment, but how long would that last? Thankfully it ended and the shield was still standing, but the towers were cracked and a couple were even inoperative.

Bart grinned as he charged up a powerful energy attack. The resistance raised their weapons, preparing for the inevitable. He finally unleashed it after several minutes, and at first, the shield withstood it. The blast continued, though, and their defense was destroyed, everyone watching in terror as their protection faded away.

Bart flew towards Springfield, since the force had knocked him back several miles. Jessica and Ralph, along with everyone on a jet sled, flew to confront him, only to be knocked away by Bart's second attack. Jessica quickly realized it was meant only as a distraction as Bart flew past them, and started blowing up what was left of Springfield.

Their secondary defenses were activated, firing powerful lasers in his direction. Unlike before, though, Bart didn't pay them any mind. He fired several beams, quickly melting them into useless metal. Laughing, he blew up city block after city block.

Furious, Ralph sped after him, intending to get revenge. He fired several shots from the jet sled, all of them hitting Bart in the back, and spinning him around. Even so, he didn't consider him much of a threat. "Hello, Ralph, long time no see." Bart grinned. "How have you been since I tore the heart out of that fat slug they call your father?" He dodged several more shots, and slapped another one away with a wave of his hand. "Not very well, then. Such a pity; I was hoping for an actual struggle before I do the same to you."

"Think again, Bart!" Jessica exclaimed, hitting him in the chest with her most powerful weapon. It sent him back, but again, Bart simply grinned, as if they were simply old friends.

"You brought the whole crowd; I'm touched." He said in a mock-baby voice, blowing up one of the artillery vehicles. "Shame you don't like me anymore; we could have been great together."

"I'll never forgive you, demon!" Jessica replied, raising her gun again. "You may look like Bart, but you're nothing like him." He fired a mild eye blast, knocking the gun out of her hand. More lasers, this time from the tanks, sent him into the ground. Those shots actually hurt, but nothing like before. Angrily, Bart blew them up, ignoring the people on sleds.

Ralph actually rammed into Bart, firing several shots into his eyes. He flung him away as he tried to regain his vision. Jessica wasn't going to give him the chance. She unsheathed her unique blades, and rushed him. Bart laughed at her futile attack, since the blades didn't go even 1 inch into him.

Jessica saw that their forces were quickly crumbling. Occasionally, they were able to drive Bart back, but it was never for long as he fired as many shots as he could towards the ground, killing anyone near them. Jessica prayed that at least some were able to get away. She wondered how he had gotten so powerful in the past few years.

The remaining members of the resistance noted that Bart had not once used a shield to protect himself. Some hoped that it meant he was weakening, while others guessed the truth; their weapons simply weren't doing anything to him.

Bart landed on the ground, waiting for their next attack. True, some of the weapons still hurt, but he didn't see the need to heal himself. He grinned at the fact that soon he would never have to see this hellhole again. They took everything from me! When I'm done, nobody will survive.

He blew up the last of the artillery, but the members on jet sleds were relatively untouched. They flew around, dodging his attacks, although they couldn't do anything to him. Jessica and Ralph flew in close, hoping to do some damage. Bart grinned, and flew below them, killing another resistance member.

By now, all they wanted to do was get the innocents out of the warzone. As the battle continued, Bart flew down and razed more of the city. Buildings stood no chance against his power, and even the remaining members could barely hurt him. Jessica followed, firing her weapons. Springfield was largely in ruins, but some of it still remained.

Eventually, though, they decided there was no point in continuing. Most of them had lost their will to fight and retreated. Ralph wanted to keep attacking, to go out on his feet, but Jessica eventually persuaded him to retreat. They decided to hide in what was left of the Kwik-E-Mart.

"What do we do now?" Ralph demanded in a whisper as he saw Bart tear apart whatever poor soul didn't escape in time.

"We wait and find survivors." Jessica replied. "Professor Frink has a few weapons in his underground lab he had under development before his heart attack. It's not much, but it's the only hope we have."

"I have another idea that someone had." Ralph informed. Once he told her, she nodded in assent. It sounded risky, but what choice did they have?

I know it sounds pointless, but there's more development in the second chapter where you see the present time. It's my first attempt at a Simpsons story, so don't be too harsh.
