On the way to Peach's Castle

At Night of the Star Festival

Bowser, Kamek, Kammy, Bowser Jr., and the Seven Koopalings were all flying towards to Peach's Castle. Bowser was holding a royal letter in his claw and reading it again as he walked.

Bowser: ""...And I know how busy you are. So I'm inviting you and whoever you bring with you to this Festival. I would kindly appreciate it if you come to this. -Yours truly Peach.""

Kamek: "And are you absolutely sure that's what it said in that letter your gratefulness?"

Bowser: "I'm positive Kamek! I know her handwriting anywhere."

Kammy: "Yeah Kamek don't be such a worrywart."

Kamek still looked a little worried then turned his head to the eight koopalings who were chatting amongst themselves.

Kamek: "What do you koopalings think?"

The koopalings stopped talking and looked at Kamek and then at each other.

Lemmy: "I say don't worry about it."

Ludwig: "Hmph. Odd? Inviting? Yes. But, I'm sure for a reason and that's to have fun."

Larry: "Yeah Kamek I'm sure the rest of us agree, so don't worry too much about it."

Kamek reluctantly nodded as they continued flying.

Wendy: "Remind me again why did we take our personal vehicles instead of our airship?"

Kammy: "Because it would make everyone in Peach's Castle thinking that were attacking them. Besides it's a little more politer this way."

Wendy then turned to Junior and Iggy.

Wendy: "I guess that makes sense. But, Why does Junior have his case of Mech-Minions and his Magic Brush in his Clown Car and Iggy having his brand new invention along with him?"

Junior: "Come on Wendy you can never be sure in events such as this. Besides the Mushroom Kingdom doesn't have a good track record in parties or events because either we make the trouble or something else brings it down."

Iggy: "Plus I can never leave something like this at home. It's called the W.E.D. or World Entering Device and I'm entrusting it to Junior."

Roy tilted his head in confusion as Iggy gave the device to Junior.

Roy: "Why are you giving that shell phone to the squirt?"

Iggy: "Junior has become more reliable ever since the whole Blorb incident and with the Brute Force Federation or something. That's why I'm trusting it to him, I don't know maybe it's just me Bwahahaha!"

Roy now understood and nodded.

Morton then spotted the castle up ahead.

Morton: "MORTON SEES CASTLE! MORTON AND FAMILY MAKE LANDINGS NOW!"

Bowser: "You heard Morton. Time to land."

All the Koopas landed in the castle front yard.

Bowser and the Seven Koopalings left their clown cars, Kamek and Kammey tucked away their broomsticks in their wands. Junior shrunk his clown car and put it away along with his case, brush, and the W.E.D. in his shell.

When they got to the door Bowser knocked on it only for the door to move on its own.

Bowser: "What the stars-!"

Before Bowser could say anything else a long purple ghostly arm came out of the entrance's darkness and wrapped around Bowser and yanked him inside.

Bowser: "BWWWAAARRGGHH!"

The 7 Koopalings: "BOWSER!"

Kamek and Kammy: "YOUR ROTTONESS!"

Junior: "DAD!"

Kamek, Kammy, and the 7 Kooplings drew their wands and charged in while Junior was still in a state of shock.

The 9 koopas disappeared as soon as battle sounds filled the castle.

Kammy: "RELEASE HIM! I-AHRRGGH!"

Kamek: "KAMMY! HOLD O-! SCRRREEE!"

Lemmy: "STOP THEM! AHHHH!"

Ludwig: "NO! ALL MY SIBLINGS! THEY BEEN TURNED INTO STONE! AAAAAARRRGGHH!"

Then the battle silenced.

Junior shook out of his shock and charged in only to find darkness.

Junior: "SHOW YOURSELF! LET MY FAMILY GO!"

The room lit up and Junior opened his eyes to see a number of toads knocked out along with Toadsworth.

Then turned to see 9 koopa statues all in battle stances.

Then looked up on top of the middle staircase he saw two human statues that had M and L on their hats.

Along with three unconscious princesses and a Bowser statue in a terrified state.

Junior was about to move forward to free his dad when he heard some terrible laughter.

?(1): "EYAH HAHAHA!"

?(2): "MAHAHAHA!"

?(3): "FWAHAHAHAHA!"

(You might remember them from the Mario and Luigi games.)

Junior then saw three dark purple spirits floating on top of the staircase.

Junior: "Who are you and why are you doing this?"

The three villains laughed again.

?(1): "I am Cackletta the mentor of Fawful!"

?(2): "I'm the Elder sister of Princess Shroob!"

?(3): "I was originally Dark Star but now I'm beginning to grow on my loathsome copy's body, you may call me Dark Bowser!"

Junior growled.

Dark Bowser: "Ahh so you are the copy's spawn I see."

Cackletta: "Why don't we play a little game shall we?"

Junior tilted his head in confusion.

E.P. Shroob: "A game of those elder tots over there. We move to different worlds gaining all the dark power we can find, while you chase us as the hero instead of those two. does it sound like fun? If no then too bad you don't have a choice to follow us the Dark Evil."

The Shroob Princess then warped away the Mario bros, Bowser, and the three princesses.

Junior was shocked to see this.

Cackletta then shot lightning at the castle wall and made a red portal with black orbs swirling it and went in, followed by the Shroob Princess.

Dark Bowser then turned around to see Junior as he moved backwards into the portal with a dark grin on his face.

Dark Bowser: "Each of the worlds we enter has 1% of dark power. Catch us in a 100 worlds if you can! FWAHAHAHAHA!"

Then he vanished within the Portal.

Like clockwork two lumas flew in trough a broken window and spotted Junior. then they flew over to him with desperate looks on their faces.

Luma (1): "Save our Mama and your Papa!"

Luma (2): "Don't worry about here we'll let everyone know what happened and to calm the panic. If you want to find another Luma in another for guidance or to power up your mysterious gadget to another world use this Star Whistle."

The Lumas gave Junior the Star Whistle and put it in his shell.

Lumas: "GO!"

Junior nodded as he ran inside the portal.

Unknown

Junior was starting to awaken.

Junior: "~Groan~ Wh-Where am I? I feel like I was falling for an hour."

He then opened his eyes and saw the portal behind him disappeared.

Then he saw that he wasn't wearing a shell only a shell like shaped backpack, a white shirt, light brown jeans, and yellow sneakers.

Junior was stunned and spotted a puddle up ahead.

He looked into it and saw a completely different shape.

Junior: (I'm a HUMAN! Must have been the effect of the portal. Lets see I have the same skin as Peach does, I still have the same green pupils, and I have red hair that is covering my head but, I still have my ponytail. To top it off I'm the same height as Peach.)

He then remembered all the stuff he had, so he took off his bag and opened it. He breathed a sigh of relief to see that all the stuff he had is still there and they still work.

Junior: (That's a relief to see they are all still here but, now that I'm a human now I can't breathe fire for now. OH! Those three spirits where did they go?)

Junior closed his bag and put it back on as he began to look around as the sun began to rise.

Junior: (More importantly where...am...I?)

He looked up to see right in front of him was the Eiffel Tower.

Three Villains have returned and are now in a another world! Where is Junior at? I'll give you a hint it's based off of a cartoon and anime show mixed together. Any guesses on which show is this? Find out next time in Bowser Jr's Multiverse Journey!
