"What? Mario is gone, and he left you a letter?" Sonic asked.

"He said he's going to find his friend King Mickey, so I have you to tell me about a key-weapon." Luigi said.

"Uh, key-weapon? I don't know about it, but I know someone who had information about the key." Sonic said.

"Who is someone?" Yoshi said.

"Wait, hold on! Your world is plunged into darkness the same happen to our world Mobius?!" Silver asked.

"Yes, those dark creatures tried to attack us in one place to another. I want to know what they are." Taiyo said.

"Those evil creatures are known as Heartless. They are born from the darkness that consumers of all living beings." Espio said.

"I see and why did they attack me?" Taiyo asked.

"They have a sense of great fear of the weapon called the Keyblade you use at them." Silver said.

"Oh, you mean this?" Taiyo asked as he summoned his Keyblade in his hand.

Chaotix was astonishing at Taiyo's Keyblade even Amy and Cream.

(Tails' Mechanic Shop)

"If the Heartless were fear of the Keyblade that belongs to the wielder, they're tracking to a person and destroyed." Lightning said.

"So how those Heartless appeared here than other worlds?" Yoshi asked.

"They were using the Corridor of Darkness as it linked as the gateway to any other worlds." Lightning said.

"So how did we stop them and defeated?" Luigi asked.

"You must find the Keyblade wielder, it is the only way to stop Heartless from invading the other worlds and let the wielder locked the Keyhole." Lightning said as Yoshi and Luigi shared a look in confused.

"A what?" Yoshi asked.

(Chaotix Detective Agency's office)

"The Keyhole?" Taiyo and Tsuki asked in unison.

"Yes. It is part of the world's natural heart and that's the reason Heartless find it." Blaze said.

"So, what will happen if the Heartless finds it?" Taiyo asked.

"They have easily devoured the whole of it from the inside. When that happens, the world crumbles into the darkness and erased everything from existence." Silver said as Taiyo and Tsuki gasped in utter shock.

"You must use your Keyblade, Taiyo. If you locked the Keyhole, the Heartless would never use it again and the world would safe from harm." Espio said as Taiyo held his Keyblade and looked at it.

"I see... Then where should I find it and locked?" Taiyo asked.

"We don't know where it is. It is hidden somewhere here, and it is really hard to find." Silver said as three Heartless Soldier appeared out of darkness along with three pairs of new Heartless Red Nocturne, Blue Rhapsody, and Yellow Opera.

The three Heartless Soldiers jumped attack at them, but Silver used his psychic to throw them up in the ceiling causing vanquished them in a puff of black smoke.

"What are we going to do?" Vector asked.

"We're going separately to fight Heartless in every three districts. Taiyo, come with me to deals with those dark creatures at Third District." Silver said as Taiyo nodded to him.

"Espio and I take off in First District." Blaze said accompany with Espio.

"We're heading out here in Second District," Charmy said along with Vector and Taiyo turned his head back to Tsuki.

"Tsuki, stay here with the others." Taiyo said.

"Okay, please be alright." Tsuki said as she embraces Amy, Cream, and Cheese in her arms.

"Be careful out there." Amy said as Taiyo, Silver, Blaze and Chaotix Detectives left the office.

Taiyo and the Mobians are outside in Backway Road.

"Before we split up, here's the walkie-talkies, guys." Charmy handed over to Taiyo and Blaze as Vector has one of radio.

"If you defeat any monsters, let us know." Vector said as Taiyo walked to Vector.

"Well, good luck to you." Taiyo said in determined.

"No problem to me, Taiyo." Vector smiled back at him as Taiyo and Mobians split up into each district.

Taiyo running to the Third District while Silver flying in levitation next to him. Luigi, Yoshi, Sonic, and Knuckles got outside as Taiyo and Silver passed through them making confused.

"Hey, who was that running with Silver?" Sonic asked as Luigi gasped.

"I knew it!" Luigi said making two Mobians and Yoshi dumbfounded.

"What?" Knuckles asked.

"That must be the Keyblade wielder and he's here," Luigi said as others realizing that.

"Then we'd better go find him and help him!" Yoshi said as he and others followed the boy and Silver's direction way.

Taiyo and Silver are now in front of the door leading to Third District with prohibited signs all over it and big lock chain.

"So, this is an entrance to the Third District with prohibited signs?" Taiyo asked looking up to signs.

"Yes, that why we need to investigate in there." Silver said as he used his psychic powers to unlock lock chain and it fell on the ground.

"Let's go in." Taiyo said as he and Silver opened the door and went in.

The door closed itself as Luigi, Yoshi, Sonic, and Knuckles run in front of it.

"Maybe they went to a prohibited district." Knuckles said.

"Yeah, let's go in there." Sonic said as they opened a door and headed in.

(Third District – Abandoned Hometowns)

Taiyo and Silver looked around the whole crumbling building which makes Taiyo uncomfortable in this day of reckoning.

The Third District is prohibited area that no one's allowed to live in any other places. It is an apocalypse municipality zone with buildings crumbling, old construction vehicles, no water, no plants, and no life.

"Wow, this is an awful place that no ones to be here." Taiyo said.

"That's right, but this is the only place we haven't looked." Silver said looking around as Taiyo saw an abandoned warehouse.

"Let's check over there," Taiyo said pointed at the warehouse.

"Good idea, Taiyo." Silver said as he and Taiyo entered a warehouse and see all the junks everywhere.

The several Shadows Heartless, four Soldiers and some magic elemental jar-like Heartless has summoned as they're about to attack.

"Let's do this!" Taiyo said summoned his Keyblade and Silver's psychic aura glowed his body. Red Nocturne and Blue Rhapsody cast their magic attack at Taiyo who dodged as he countered jump attacked at them with horizontal slashed at the same time and he lands on the ground. Silver blasts his psychic on some Shadows and two Soldiers disintegrated into a puff of smoke. Taiyo takes out two Soldiers and three Yellow Opera with strikes combat. The Heartless are retreating from them as radio beeping as Silver and Taiyo picked up their communicator devices.

"Hey guys, we took care of Heartless at Second District, Espio and Blaze have already defeated some of them at First District." Charmy's voice on Taiyo's radio.

"What's your report?" Vector's voice on Silver's radio.

"Taiyo and I finished those creatures." Silver talked to his radio to Vector.

"Good! But there's only one problem." Vector's voice on Silver's radio.

"What is it?" Taiyo asked to his radio to Vector.

"There are two hooded figures out of nowhere and one of them is viciously stronger. My pals and I never seen it before." Charmy said on Taiyo's radio.

"Then who were they?" Taiyo asked as their radios began jamming.

"Hello? Hello? Hello? Answer me!" Silver said as their radios died.

"Our radios are being jammed." Silver said.

Taiyo and Silver heard two evils laughing coming from the dark in the warehouse as they saw two hooded figures walking to them. One of them takes off his hood and reveals as Bowser Jr.

Bowser Jr. was one of the Koopalings and son of Bowser. His body has a yellow skin tone that lacks the tan seen on his dad and most of the Koopalings, as well as a light green head, with small horns on each side, each being circled with orange rings, small circular eyes, that are black in color and black sclera and irises, as well as his father's fiery orange hair and eyebrows; his hair is tied up into a top-ponytail. His mouth is wide, puffy, and con-vexed, with a large snout having one, fang-like tooth in the upper left corner. Bowser Jr has little hands and little padded feet, which have small white claws. His shell is green, lined with a white encasing, and the multiple, short spikes are circled with orange rings, similar to his father's shell, while his belly is plated, with four ribs.

Silver gasped at him in surprise while Taiyo looked disinterest at Koopa.

"Bowser Jr? What are you doing here?" Silver asked.

"Bowser Jr, huh? More like a little baby cretin." Taiyo said as Jr growled in annoyance.

"I'm not a baby cretin and nobody calls me that!" Bowser Jr shouted at him as he tried to attack as his partner stops him with his katana blade against Bowser Jr.

"That Keyblade wielder was mine." He said as Taiyo gripped his Warrior Key.

"You must be his partner, whoever you are." Silver said.

"If you must know... He takes off his hooded clothes and reveals his appearance to them.

Snide is an evil alter-ego side of Heckyl, yet powerful and grey metallic-armored alien from Power Rangers Dino Supercharge. Snide has one yellow eye, top of his head embedded with a dark blue jewel, given resemblance to Zeltrax and his mask mouthpiece was imprinted with dark blue runic patterns resembling like his transform tattoo.

Taiyo and Silver have glanced at Bowser Jr.'s deadly partner in alarmed.

"I never have seen that monster before but looks dangerous." Taiyo said as metallic armored figure chuckled evilly.

"Dangerous looks to me. I'm Snide, your worst and deadliest enemy." Snide said pointing his katana blade at him and Silver.

"Be caution yourself, I sensed on his limits were strong." Silver said.

"But maybe we'll fight one another soon as I summoned the strong Heartless." Snide said as he snaps his fingers to summon boss Heartless.

Taiyo and Silver feel the ground shaking tremendously but stand prepositionally.

"Why is this shaking on a ground?" Taiyo asked.

"I don't know but I hear it's coming out." Silver said as the driller burst out of the ground still drilling and it emerges out of the ground. The Heartless looks tougher and bigger called Junk Scraper.

"Surprised to meet Junk Scraper!" Snide said as it's roared at Silver and Taiyo.

Junk Scraper is an Emblem Heartless boss made of metal scrap. Its body color is red-brownish, it has a giant screw on top of its head, its Heartless emblem was on a chest resembling junk car bumper, its two arms were excavator's claw and big driller and its two legs and feet was road wheel.

"Get ready, Taiyo." Silver said as Taiyo took on battle positions.

Junk Scraper slammed its excavator's claw on them, but they jumped away and Taiyo counterattacks few strikes its legs. Junk Scraper growled at him as it swiped its drill arm at Taiyo and making him slides across the ground.

"Taiyo, you're alright?" Silver asked looked worried as Taiyo held his arm with his hand.

"I'm fine, just a bruise." Taiyo said.

"Let me do it." Bowser Jr said as Snide grunts.

"Fine, I let you do it." Snide said as he leaves Bowser Jr to deal Silver and Taiyo as disappeared in the darkness.

Silver dodged from Heartless boss and sending psychic wave energy toward Junk Scraper. Junk Scraper launches its drill at Silver as he flies dodged from drill launch attack but got fire blasted by Bowser Jr making him fall on the ground stunned. Bowser Jr brought out his Magic Paintbrush and whacked at him but blocked by Taiyo's Warrior Key vertically.

"I didn't know you learned how to fight, Bowser Jr." Taiyo grunted.

"Either you are." Bowser Jr said as he let out fire breath at him, but Taiyo jumped over in behind of him.

Taiyo mighty strike at him as he sent flying to the wall crashed. Before Taiyo finished him off as Junk Scraper grabbed him with its claw and smashed him on the ground three times. The boss Heartless throws Taiyo on the ground and rolled across. Silver comes to aid him but smacked by Bowser Jr's Magic Paintbrush and spewed fireball to knock him downfall next to Taiyo.

"Junk Scraper, finished them." Bowser Jr ordered as Junk Scraper spins its drilling hand ready to finish them. A green fireball shot out of nowhere as it exploded its face.

"Grrrr. Who did that?!" Bowser Jr growled as Taiyo and Silver saw Luigi and Yoshi coming to them.

"Luigi and Yoshi, where were you?" Silver asked as Luigi and Yoshi saw Taiyo who still hold his Keyblade.

"Looks like you found a boy with a Keyblade." Yoshi said.

"Here." Luigi said as he throws two mushrooms at Silver and Taiyo.

"What are these mushrooms?" Taiyo asked.

"Eat it and you'll be healed." Luigi replied as Silver and Taiyo eats the two mushrooms as light green aura emitted on their bodies and healed them.

"Whoa, I'm recovered up." Taiyo said as he and Silver stand on their feet.

"Jr, what is exactly Bowser want to do?" Luigi demanded as Bowser Jr chuckled evilly.

"My daddy has got lots of plan than kidnapping Mama Peach. He's going turn all the worlds into darkness. Also, Papa Bowser going to find Mario before he was searching for his friend King Mickey." Jr said.

"Who's Mickey?" Taiyo asked.

"Mickey was king of Disney Castle Kingdom as a ruler. Papa told me that Mickey knows the darkness threatening in every world in the universe." Bowser Jr said as Taiyo gasped in shock.

"You mean helping the Heartless to conquer all the worlds and consuming into darkness?" Taiyo asked.

"That's right but I'm still learning about this conquering thing. Well anyways, Junk Scraper take care of those twerps when standing my way." Bowser Jr said as he used his Magic Paintbrush to open the dark portal and entered it.

"Ughhh. Jr is getting away." Yoshi said.

"But we got bigger Heartless to take care of." Taiyo said as Silver, Yoshi and Luigi nodded at him and ready to defeat Junk Scraper.

"Here we go. Thunder Shot." Luigi said as he summoned a green sphere of electricity at Junk Scraper making stunning damage.

Taiyo amazed at Luigi's electric attack.

"What was that electric?" He asked.

"Oh, let's say I'm a master of electrokinetic." Luigi smirked.

"Wicked!" Taiyo yelled as he sensed Junk Scraper tried attack behind himself and jumped on its head.

Junk Scraper roared at him as shook him off its head, but Taiyo managed to hold on and strikes four times. Junk Scraper roared in agony as Taiyo jumped off its head and land on the ground. Yoshi jumped higher at Heartless and spin kicked at Junk Scraper's face. Silver levitated junk car and chuck at Junk Scraper more damaged. Junk Scraper was weakened as it's laid on the ground.

"It's weak, let finished it!" Silver said as the four heroes finished it as Taiyo's crystal Kingdom Hearts sigil glowed in bright white making Luigi, Yoshi and Silver surprised as wisps towards to Luigi and Taiyo.

Taiyo and Luigi have somehow unlocked Limit Breaks which allowed combining their skills. Four heroes looked in amazed.

"Whoa! What just happened then?" Yoshi asked.

"That wisps came from the crystal necklace that surging into Taiyo and Luigi." Silver said.

Taiyo and Luigi felt their mysterious energy running their veins. "That energy was... Limit Trance." Luigi said.

"Limit Trance?" Taiyo asked.

"The phenomenal life-force said to be through all the living beings and given us the power of Limit Breaks." Luigi said.

"Limit Break, huh? That is cool and used it." Taiyo said as he and Luigi combining their attack.

"Green Volt Strike." Luigi and Taiyo said in unison

Luigi burst the green lightning ball as Taiyo threw his Warrior Key at the electric sphere which transformed into a powerful ball of green lighting and straight at Junk Scraper. Warrior Key came back to Taiyo's hand as Junk Scraper roared in pain got incredibly exploded in electrified and defeated. The Heartless boss glowed in bright light, revealing a heart that flew out of it and disappeared. Junk Scraper vanished in a flash of light.


Author Notes: Taiyo encountered the two villains; Bowser Jr. and most of the worst enemies of the Power Rangers is...Snide! Snide somehow revived after Dino Charge Rangers defeated him in battle before the Dark Energem destroyed and turned into the black hole to suck Sledge's ship and Planet Earth.
