Chapter 1: Declaration of War
(Disclaimer! I own nothing of Nintendo, Steven Universe, Star Butterfly, Kirby, or anything else! But I do own this story.)
The Cosmic Star, it is an artifact of unimaginable power. Housed within it is the very thing that my master has spent years searching for. The master has found an ally with Mewnian. I have trusted him with the staff that houses some of the artifacts power. He is ready to rule, ready to conquer. There is a planet that is more than useful to begin our new kingdom. A planet called…. Earth. That is where the Cosmic Star was last located. Our army, it will take over this planet. And the humans? What more can they do, but burn?
S.M.A.S.H secret base. 23:00 hours
There were soldiers going around doing secret work. Others were evacuating the facility while researching the Cosmic Star. One of them saw a helicopter. "Soldiers!" she said, "He's here." The helicopter landed. From it came Captain N, Princess Lana, and Pit. "So what did you find?" he asked Captain N, "How bad is it?" "That's the thing," said Professor Elvin, "We're not sure." They were going into the room where the research was taking place. "I don't recall saying you should go into tests," said Captain N. "I didn't, it just turned itself on," said Professor Elvin, "That's why Pit ordered an evacuation." "We best get ready for phase 3 of our weapons," said Captain N. "Kevin, are you sure that's the top priority right now?" asked Lana. "Unless the earth is gonna explode we best act like it still intends to spin," said Captain N, "The last thing we need is world wide panic."
Elvin was looking at the Cosmic Star. "It seems like its acting on its own will," he said. "That supposed to be a joke?" asked Captain N. "Its not," said Professor Elvin, "Normally I am prepared for this kind of thing, harnessing energy from other dimensions, but the one thing we're missing is the harness." Captain N noticed his ally Meta Knight in the sky. "Meta Knight, report," he said. They were talking. "Things for me are better seen from a distance," said Meta Knight. "You should keep a close eye as well Meta Knight," said Captain N.
"Professor!" said a scientist, "Its spiking again." The base was rumbling and then a portal opened up. "What the hell…" said Pit. From within the portal came a man with a spear glowing with blue energy. He looked around. "Who or what is that?" asked Lana. "Shoot first, ask questions later," said Captain N, "Fire!" Before the soldiers could act the man quickly dashed around them and knocked them out cold. Meta knight snuck behind him but the man was quick. He used his staff to put him under his control. Captain N saw this as an opportunity to grab the Cosmic Star and run.
"I wouldn't do that if I were you," he said, "I need that." "Who are you?" asked Captain N. "My name is Comet Dragonfly of the planet Mewni," said Comet, "And I was born with the soul purpose to rule." "Well find another planet," said Captain N, "This one's off limits." "Comet, Captain N is stalling," said Meta Knight. "My men beg to differ," said Comet as he snapped his fingers. One of the soldiers shot Captain N and he dropped the suitcase. Meta Knight took it and started to leave. Lana saw him and other soldiers leaving with the Cosmic Star. "Lana!" said Captain N, "Meta Knight has been compromised…."
Lana took out her pistol and started shooting. Meta knight deflected them with his sword. There was a vortex of energy in the testing room. "All personnel go after Comet!" said Captain N. There were soldiers on cars chasing him. "Try all you must," said Comet, "You're just denying the inevitable." He used his staff to slow them down shooting bolts of energy. Other soldiers were evacuating the area before the place explodes. Lana was close to Meta Knight's car. He sped up and pushed Lana to the side and she fell out. Pit swooped in and saved her. "You ok?" asked Pit. "Yeah, thanks to you," said Lana, "Where's Captain N?" "I'm alright," said Captain N, "Right now we gotta get outta here!" Everyone made it out safe. The base collapsed to the ground and was reduced to ashes by the blue energy. "Is everyone ok?" asked Lana. The soldiers gave thumbs up.
"I knew this was gonna happen," said Pit, "I told you messing with that star was a bad idea." "Anyone who isn't in injuries should get to work locating Comet and the Cosmic Star," said Captain N, "As of today, Earth and another dimension are at war." "What are you gonna do?" asked Pit. "I'm gonna get ready," said Captain N looking at the files he received.
