A/N: This story takes place in the events of Super Mario Galaxy, told through both Mario and Lucina's perspectives. Unlike one of my other stories, a Smash Bros. fanfic called Smashers in the Hotel (where there's a Mario x Lucina ship), Mario x Lucina will NOT (I repeat, NOT) be a romantic relationship in this one, as the ships in this story are Mario x Peach and Lucina x Robin. Instead, Mario and Lucina will undergo a friendship-esque bond in this story during their journey to save Peach and Robin. Also features a guest character from the Granblue Fantasy series, who will appear alongside with Luigi as supporting characters.

Mario and Lucina's Interstellar Adventures Across the Galaxy

A Christopher Spielberg fanfic

PROLOGUE

Every hundred years, a shining comet appears in
the skies above the Mushroom Kingdom. The
comet was so large one year, it filled the skies
and sent down countless shooting stars raining
down, creating a beautiful display for all who
witnessed it's stargazing sight.

In the Mushroom Kingdom, the Toads brought
the shooting stars to the castle, where they all
become a great and luminescing Power Star.
It should have been a very happy time for the
wonderful citizens of the Mushroom Kingdom.

That night was remembered as the magnificent
Star Festival, held once every hundred years in
the Mushroom Kingdom to celebrate the comet
and witness the spectacular view of the shooting
stars in the night sky...

The Mushroom Kingdom
The Night of the Star Festival

Lucina, the daughter of Chrom, and her girlfriend Robin from the land of Ylisse, both arrive at the Mushroom Kingdom on that special night.

Robin asks her girlfriend, "You sure this is the place?"

"It...looks like it.", said Lucina, who took out and looked at the invitation they were given;

Dear Lucina and Robin,

You're invited to the Star Festival. Enjoy the one night opportunity to see the majestic view of the comet that comes once a century. Don't miss it!

Sincerely Yours, Princess Peach

The princess of Ylisse then replies, "Like what the invitation says, it sounds and looks promising."

"I can't wait to see the stars with you.", anticipated the Plegian shepherd.

Lucina nods, "Let's go.", as the two advance their way to the kingdom...

...but not before a familiar red plumber follows behind them, who is also on his way to the Mushroom Kingdom for the festival, jumping in the air for one moment and saying, "Wa-hoo!"

Once the couple reach the kingdom, the two smiled as they saw the Toads happily collecting shooting stars and spending the lovely night. A guards each appeared between the path ahead while other Toads were seen.

"It's...so beautiful...", Lucina says with glee, about to move along with Robin before she felt someone bump behind her.

Lucina and Robin turn around to see who bumped into this, before seeing the same red plumber from earlier.

Mario.

"Oh! I'm-a so sorry.", the red plumber said, "Didn't see you too coming."

The blue-haired girl said to her, "That's okay. We're heading to the Mushroom Kingdom for the Star Festival. We recieved a letter saying we're invited. Are you invited as well?"

"Well, yes, but I received a different invitation...", Mario says as he showed his letter to Lucina and Robin;

Dear Mario,

I'll be waiting for you at the castle on the night of the Star Festival. There's something I'd like to give you.

From Peach

Lucina replies, "It's from the same person. The Princess Peach?"

"Of-a course. She's-a the love of my-a life.", said Mario, "We've-a been in love since the day I've-a saved her."

Robin giggled, "I assume she has a gift for you."

"Right-a you are!", the plumber smiled, "Maybe if it's-a not-a bother, maybe you two would like-a to meet-a the Princess? Wanna come?"

The Exalt girl answered after chuckling, "Yes. Why not? We're going to the Star Festival too, after all.", as the three then went on their way to the festival and Peach's castle.

Once there, the three gasp in awe as they saw many Toads and other guests celebrating the night of the Star Festival. Guards, peasants and all else.

"Luigi!", Mario greeted.

The green plumber says, "Mario!", before he and his brother hugged.

"That must be your brother, huh?", Lucina smiled.

Mario says, "Right, indeed. Luigi, this is Lucina and Robin. Lucina and Robin, Luigi."

"Pleased to meet you too. We've been invited for the Star Festival tonight, and-", Robin greeted again.

Luigi then said, "Hey-a, guys. You wouldn't believe who I-a met recently.", before saying, "Everyone, this is my-a friend Katalina.", bringing over another guest visiting for the Star Festival, Katalina.

Although she looked similar to Lucina, she had long, pale blonde hair, red eyes, large stature and broad shoulders, while her attire is mostly worn in armor with a blue-colored cape like Lucina's.

"Hi. My friend Luigi here just told me about his brother, Mario. And you are?", the blonde knight asked.

"I'm Lucina. And this is my girlfriend Robin. We're here for the festival."

Robin then tells her, "I'm just gonna go to the castle to see Peach for a bit. I'll meet up with you guys soon."

"Alright. We'll catch up.", Lucina nodded as Robin left to go to the castle not too far away from the plaza, "So wait are you planning to do for the festival."

Katalina answers, "I don't know, maybe catch some stars, maybe collect them as souvenirs..."

"We-a can even gaze at stars-a with our friends and-a loved ones.", Mario adds.

Luigi high-fived, "That's the spirit, Mario!"

"Now, it's time to meet up with Robin, see Princess Peach and-", Lucina said-

Suddenly, they heard cannons blasting as many cannonballs strike the plaza, one knocking down a building!

"GET DOWN!", Lucina said as the four ducked.

It appeared that several airships were heading towards the Mushroom Kingdom, still striking cannonballs where the heroes are!

Luigi shivered in fear, "W-w-w-w-w-wha-a-a-at's-a going on?"

"We're under attack!", Katalina said, as another cannonball hits another building far away from them in the plaza.

Lucina sensed, "Robin's in danger!"

"Peach!", Mario sensed as well, before he said to Luigi and Katalina, "Go, Luigi and-a Katalina! Go where it's-a safe! We're-a going to save-a Robin and-a Peach!", as the two couples split up and went off.

Mario and Lucina, dodging cannonballs and fireballs colliding and exploding in the plaza, then gasped as they stopped and saw the airships arrive and passing by in the air, appearing to be led by the villainous Bowser, nearing Peach's castle!

Peach witnesses the chaos in the kingdom as she carely held the precious white Luma in her arms, while two Toad guards looked on.

One of the airships then neared the castle as someone steps forward and meets with Peach.

Bowser himself.

"Princess Peach! You are formally invited...to the creation of my new galaxy!", Bowser declared as the Toad guards cowered in fear behind the princess as Peach clutched the Luma tightly, not wanting the star to get harmed.

Bowser laughs evilly as he unleashed a massive amount of energy, "THIS FESTIVAL'S OVER!"

Inevitably, a saucer appears in the scene, making the catastrophe even more frightening.

Robin witnesses the entire thing when she arrived at the castle and said, "What's going on?!"

Peach, on the other hand, sees this as the UFO reflects in her eyes as she witnessed in danger.

Back at the festival, Lucina says to Mario, "Come on! We need to keep moving! We gotta save them!", before they start running on their way to the castle in a hurry.

"How could this happen!?", one Toad said.

Another said, "Going to my happy place...!", as the two heroes ran.

As the two reach the Castle Gardens, they heard Peach and Robin yell out, "HELP ME!"

"ROBIN!", Lucina shouted.

Mario also shouts, "PEACH!", as they head towards the bridge and ran across the grass.

But as Robin was about to reunite with Lucina, the saucer appeared right on top of the castle and, when its red bottom parts turned green, it suddenly shot lasers after it positioned its lasers, tracing around the castle in a circle.

Peach almost loses her balance when the earth shifted, as the bridge Lucina, Mario and Robin were on shattered, separating Lucina and Robin (with the former still with Mario) by the force!

Chains went down from the airships as they dug into the ground, where in several moments, the castle is lifted away from the ground, bringing Mario, Lucina, Robin and Peach up!

The castle went higher and higher by the airships as the UFO lead the way, leaving the atmosphere as it enters into outer space!

"MARIO!", Peach called out in danger.

Robin also said, "LUCINA!", as she tried to reach her by crossing the cracked bridge.

Mario and Lucina pant as the latter looks below, seeing how high they were going by Bowser's armada of airships.

"This is...too high...", Lucina said to herself, before saying, "Don't worry! I'll come get you! Just stay calm!", just as she was about to reach Robin with the broken bridge while Mario reached out for Peach,

"Peach...", said Mario.

Lucina ensured to Robin as she almost reached her girlfriend, "Everything's gonna be-"

Suddenly, Kamek appears and snatches Robin!

"ROBIIIIIIIIN!", yelled Lucina, as Mario sees this.

Lucina pulls out and readies her Falchion sword, glaring on at Kamek as she grunted with anger.

Kamek says to the two, "So long! Enjoy your flight!", as his wand glowed with power before Kamek was about to cast a spell at the two!

"NOOOOOOO!", Robin shrieked, watching in horror as Kamek casts his spell.

The spell headed towards Mario and Lucina, the latter managing to block it, but causing the castle bridge to be destroyed completely as the two were sent flying off in space!

"AAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHH!", screamed Mario and Lucina as they were sent flying away into space!

As Kamek cackles in victory and disappears after settling Robin with Peach, they let out;

"MARIOOOOOO!"

"LUCINAAAAAAA!"

The castle then disappears and warps away by another spell of Kamek's!

But before it does, the white Luma star escapes and flees its way to find the two heroes...
