The Mysterious Star. A peaceful traveling star with seven different countries ruled by kingdoms; the Flame Kingdom, the Seed Kingdom, the Jewelry Kingdom, the Waterdrop Kingdom, the Windmill Kingdom, the Moon Kingdom, and most importantly, the Sunny Kingdom.

This magnificent world faced a great peril when the Sunny Kingdom's power source that helps provide for the rest of the kingdoms, Blessing of the Sun, became in danger of going out, therefore spelling darkness and despair

However, the two young crown princesses of the Sunny Kingdom Fine and Rein, managed to use the magical power of the Prominence passed down to them by Princess Grace to save their home from disaster. However, a brand new threat is about to make itself known to the residents of the Mysterious Star...and this time, they will need help from Heroes beyond their world.


It was a beautiful day in the Mushroom Kingdom, guarded by the brave heroic plumber brothers Mario and Luigi. Currently, they were having a tea party with Princess Peach, and thankfully, their archnemesis, Bowser, wasn't around to cause problems.

"It's so nice to be able to spend a day without Bowser or his Koopa Troop causing trouble, right boys?" Peach said as the Mario Bros. nodded in agreement.

"Princess! Mario! Luigi! Come quick!" Came the alarmed voice of one of the Toad messengers. "A mysterious pipe has just appeared in front of the castle grounds!"

"What do you mean?" Peach asked as the Toad decided it was better to show her.

Heading outside, everyone saw a large pipe coming out of the ground. It was different from most pipes in the Mushroom Kingdom as it looked to be made of sparkling crystal and decorated with magnificent stars.

"Oh my, what could a pipe like this be doing here?" Peach asked.

"Could it-a be like the pipe that led to the Sprixie Kingdom?" Luigi guessed.

"Hmmm..." Mario hummed as he leaned his head into the pipe before seeing a golden light coming from it and quickly backed away to let it pop out of the pipe.

"Brave heroes of the Mushroom Kingdom...I am Princess Grace, the former ruler of the Mysterious Star. I am in dire need of your help, as someone you know is trying to take the star for himself."

Everyone saw an image of Bowser's Castle floating through unfamiliar lands, no doubt it was a part of the Mysterious Star he was invading.

"Bowser never-a gives up, does he?" Mario frowned, clenching his fist.

"Let's-a-Go, Mario! Even if he's not-a after the Mushroom-a Kingdom this time, we can't let Bowser have a-his way!" Luigi declared.

"Be safe, boys!" Peach said worriedly as the Mario Bros. leaped into the crystal pipe together to a brand new adventure.


"Ah, fresh air!"

These were the words said by Sonic Maurice Hedgehog, Hero of Mobius and the Blue Blur. Currently, he was racing through one of his favorite places to be when he just wanted to run and feel the wind in his hair; Green Hill Zone.

"It's been a while since ol' Egghead has been up to his old schemes. Wonder what he's hatching now so I can see if I can scramble it!"

Suddenly, a missile seemed to be heading toward Sonic and he quickly skidded to a stop as it landed in front of him. However, it was revealed to not be a missile but in actuality, it was some kind of pod that opened up a television screen with Eggman communicating through it.

"Ah, Sonic, I bet you're wondering why I haven't been up to any schemes in eliminating you and your friends like usual. Well, that's because I have discovered a new target to conquer! Behold!"

The screen showed what appeared to be some kind of traveling hollow star that then zoomed in to show seven different kingdoms. It then cut to show Eggman's Egg Fleet looming over a desert, no doubt setting up shop there.

"And guess what! I ran into an old friend of mine, Bowser! So this time, neither you nor Mario can get in our way! Don't worry, my old nemesis, I'll make sure to write from time to time!"

The screen then cut off and the pod began beeping. Realizing it was going to explode, Sonic ran away from the blast radius as quickly as possible before frowning.

"That no-good Eggman! Thinking he can have better luck against a different world this time? Not on my watch!"

"Then allow me to help you reach your destination."

Hearing the unfamiliar voice, Sonic looked around only to see a glowing orb of golden light floating in front of him. Suddenly, it manifested a doorway with a golden star on it.

"This door will lead you straight to the Mysterious Star, where your enemy is attempting to take over. I ask for your aid in helping save our beloved star."

"A new planet to explore, huh? Sounds fun! Alright, Eggman, here I come!" Sonic smiled as the door opened and he ran inside, eager to embark on this new adventure.


In the whimsical world of Dreamland on the Planet Popstar, the brave, kind, and positively adorable hero, Kirby, was taking a nap under a tree. The pink puffball's rest would soon be disturbed by an unfamiliar voice that radiated a motherly aura.

"Kirby...brave champion of Popstar...we need your help. Our world, the Mysterious Star, is in danger and you are one of the only ones who can save it. I believe you have what it takes to put a stop to the darkness..."

Opening his eyes, Kirby looked around to find the source of the voice except for a strange star-shaped portal. Despite his confusion, Kirby knew he couldn't let those in trouble be without aid so, steeling himself, the super tough pink puff leaped into the portal to a brand new adventure.


In a big purple country with a house standing by the giant letter 'E' in the word 'States', a young boy with spikey blonde hair and his anthropomorphic Bengal Tiger companion were in a rut.

"I can't believe Mom and Dad didn't believe we really did go see dinosaurs in our time machine." The boy, Calvin, said in annoyance.

"I don't entirely blame them." The tiger, Hobbes, said behind his hand with a grin.

"Hey! What's that supposed to mean?" Calvin asked.

"Nothing..."

Calvin turned to his Time Machine; a cardboard box with the aforementioned words scribbled on it.

"Anyway, I need to make some kind of new use for this. I've tried Transmogrifying, Duplicating, Time Travel, etc...but what have I not done yet?"

"How about Dimension Travel?" Hobbes suggested on a whim.

Calvin's eyes lit up as he turned to his buddy. "Hobbes, you're a genius!"

Taking out a marker, Calvin scribbled out 'Time Machine' and replaced it with 'Dimension Traveler'. Grinning proudly, the young boy jumped inside and patted an open space for Hobbes to get in.

"Come on, buddy! We're going to a new dimension! Hopefully, one where humans live with dinosaurs! Or maybe one with free money that we can snag and bring back here to become rich!"

"I dunno seems like this might go wrong...just like all your other inventions."

"Hey! This one'll work, ya fleabag!" Calvin snapped as Hobbes got inside the Dimension Traveler and, in a flash of light and the power of whimsical imagination manifest into reality, the duo disappeared, unaware they were about to embark on a great adventure...


"Alright, Sockhead, tell me what you got!"

In a humble Cul-De-Sac residing in Peach Creek, Minnesota, a young teenage boy named Eddward, or Double-D as his friends called him due to the two 'D's in his name, was about to demonstrate his latest invention to his two closest compatriots, Ed and Eddy.

"I'm glad you asked, Eddy!" Double-D said. He had golden blonde hair, a black beanie hat resembling a sock, a tomato-red t-shirt, purple shorts, long red socks, and light blue shoes. "This device took me five months to complete. It can allow us to view planets and stars OUTSIDE our known solar system!"

"Cool! Now we can finally see if the aliens of Planet Tarkos are real!" Ed said excitedly. He had feathery auburn hair, a unibrow, a dark green jacket, a red and white striped t-shirt, light purple pants, and black shoes.

"Double-D, if you can find life outside the solar system, we can become famous!" Eddy grinned. He was relatively short for his age and had blue hair done up in three asymmetrical spikes and wore a yellow t-shirt with a purple collar and red vertical stripe, light blue pants, and red shoes. "Not to mention RICH!"

"I have no interest in monetary gains, Eddy. I simply wish to discover the furthest boundaries our world has to offer!" Double-D said as he pressed some buttons on the control panel and stepped back as the device sparked to life, soon firing a beam into the sky that cut through the clouds above and reached out into the depths of space.

The Eds all gazed in awe as the device soon began forming some kind of dimensional window. Turning their attention to it, they saw a traveling hollow star that soon revealed that inside was an entire world housing seven different kingdoms.

"Amazing! We've discovered extraterrestrial life!"

"We'll be rich, I tell ya! RICH!"

"It is the Seven Kingdoms of Light from Royal Quest VI: The Mysterious Star!"

Overwhelmed with excitement, Ed ran towards the dimensional window before his friends could stop him. Suddenly, much to their shock, he went through it as if going through a portal, disappearing into the other side.

"ED!"

In fear for their friend, Double-D and Eddy ran through the portal as well, which soon closed behind them as the device shook before settling down, the beam it was shooting into the sky fading away and leaving behind only quiet.


What none of these heroes realized was that their paths would soon be crossing in the most unorthodox ways...and it would involve two young girls who were considered the most unprincesslike princesses in the whole of the Mysterious Star.


Welcome to the start of what I hope to be a bullshit crossover franchise! Having been inspired by the works of Nan the Keyblade Master and Bloodyguy, I've decided to throw my hat into the ring and see if I can make this work, and what better way than by involving an anime that is severely underappreciated; Twin Princesses of Wonder Planet.

If you haven't heard of this anime already, I highly recommend you check it out. It's not a major showstopper, but it's adorable, quirky, and silly and I feel like sometimes, we need stuff like that in this day and age.

Now, there will be more crossovers as this franchise progresses, but the main ones will be Twin Princesses combined with Mario, Sonic, Kirby, Calvin & Hobbes, and Ed Edd n Eddy! Stay tuned for how the heroes of these six worlds collide in the next chapter!
