As Bart and the others headed to the damaged remains of Springfield caused by Zim, Chief Wiggum is shocked to see Zim attacking Bumblebee Man.

"El Alieno" shouted the overweight Latino man in bee suit.

"Holy crap, it's Alf," said Wiggum, pointing to the brown alien who was running away from the attack.

"All this for a crappy cameo," said Alf, who got blown away by Zim's ray gun.

"He killed Alf," said Milhouse.

"Hold it right there, Zim," ordered Bart, as the Irken turned to him. "Time to end this."

"You got that right, Bret," said Zim, as he pointed his gun at Bart.

Bart groaned after Zim said his name wrong. "For the last time it's Bart!"

"Say goodbye, Brit," Zim fired his gun at Bart, but a familiar person pushes Bart to the side.

"Ash?" Lisa was shocked to see Ash back from the dead. "Wait a minute. How did you come back from the dead? You were killed in Hellhomer."

"Look, kid, anything can happen in fan fiction," said Ash. "Time to kick alien butt!"

Ash pulled the cord to his chainsaw arm, but found out he was out of gas, as Zim fired at Ash. Ash dodged the beam, as he took a baseball bat to whack Zim in the head.

"That hurt, human," said Zim. "But you will pay for that, Nash."

"It's Ash, alien jerk," Ash corrected Zim.

"No matter, I take over this stupid planet anyway I can," said Zim, as be pressed a little red button on his belt. "In 24 hours, your planet will be destroyed."

"Oh no," said Lisa, as she turned to Ash. "Ash, you got to do something."

"Kid, I stopped the Army of Darkness and the Evil Dead, I don't know anything about aliens planning to blow up the Earth," replied Ash, as Lisa groaned.

"Looks like this is the end," said Bart. "Wait a minute, maybe not…"

Bart grabbed a nearby skateboard, and rode it towards Zim, grabbing the belt with a yoink. Zim roared with anger at this, and planned to shoot Bart with his laser gun, but it was on his belt that Bart took.

"How could the mighty Zim be beaten by a ten year old Earth Brad?" Zim asked himself.

"IT'S BART!!!" Bart whacked Zim with his skateboard.

Just then, a small robot was riding on Spider-Pig, heading towards Zim. "Look what I found," said Gir. "Piggy. I love pigs."

"I know, Gir," groaned Zim. "Can this day get any worse?"

Just then, two men in black suits walked towards Zim. One man was white, and the other man was African American.

"Look, Bart, it's the Men in Black," said Milhouse.

"And the black guy is Will Smith," Bart said cynically.

"Zim, you crossover with the Simpsons is over," said Agent K, as he turned to Agent J. "Slick, cuff the Irken."

"Right, Agent K," said Agent J, as he put handcuffs on Zim.

"How could he be Agent K, that I'm Agent K?" A British woman with white hair and a black outfit came out of nowhere from a jetpack.

"I'm Agent K from the Men in Black," said Agent K, to the woman. "And you are…"

"Agent K from the Replacements," said the British woman.

"Great, now Disney has joined the fray," groaned Bart. "First, it was Invader Zim, then the Men in Black, now the Replacements. What other cartoon series is going to pop up next?"

"Mmmm….peppermint," Homer came from nowhere, and grabbed Zim's belt from Bart. "If I can get this candy off of this belt…"

"NOOOOOOOOOOOOOO!!!!" Everyone shouted to Homer not to press the button, but he did anyway.

BOOM!

The Earth blew up.

Not Quite The End

The Simpsons will return in "Springfield Invasion 2: Revenge of the Crossovers," Coming Soon.
