Back at Ted Turner's place, Scrappy's cell phone rang.

"Like service must be really good even in outside of its original dimension." Shaggy joked.

Scrappy answered it "Scrappy-Doo here. Jessica? What is it? You found the crowns? And you also found what?"

After a pause, he continued. "Just follow the instructions on the magic book. Once we finish off Zin, we'll be right over!"

"What happened, Scrappy?" Daphne asked him.

"Good news is that Flim Flam and the others have found the crowns" Scrappy explained "Bad news is that we have to do a coronation ceremony within the next...21 minutes or we'll vanish forever!"

"Zoinks!" Shaggy exclaimed "I always imagined we'd go out in some sort of restaurant incident!"

"Jeepers" Daphne gasped.

"Heavens to Murgatroyd- I mean Delaware!" Mudsy gasped "We've gotta get back to Boomerang Land, but how, where, when, why even."

"Dude, like that makes no sense" Shaggy pointed out.

"Do you have anything that could potentially help us, master?" Scooby asked the Green Dragon.

"I am sorry my young friend" the Green Dragon told them "I'm just a dragon. I can't teleport."

"Looks like we really are going to die" Daphne said sadly. "But at least we'll be together."

"Yeah" Shaggy nodded as he and Daphne pulled closer to each other. "It's better than dying alone."

Just then, a portal to Boomerland opened up nearby, and everyone were surprised by the blue electro rays that opened the portal.

"Wh-wh-what's going on?" Mudsy stammered.

"Like, I'd recognize that ray anywhere." Shaggy pointed out. "It represents the power of the Sword of Doom."

"The Sword of Doom?" Daphne exclaimed. "Our friends must be in trouble!"

"Hop on, everyone." The Green Dragon said. "We don't have much time!"

Immediately, the heroes hopped on the dragon and took off, flying through the portal and into Boomerland.

Meanwhile back at the castle, the kids were still crying and upset, unaware that their colors returned temporarily.

"Kids" Charlie shouted as he, Ruff, Reddy and Jessica raced down the stairs with the rest of the animal characters. "We've found the crowns and the second copy of the magic book!"

"Daddy?" Mimi looked at her father with her face soaked with tears.

"What's going on?" Flip asked "And why are we not gone?"

"Ruff and Reddy just found the crowns." Charlie explained. "When that happens, our colours and strength are restored temporarily for an extra hour."

"Yeah but we only have 12 minutes left" Jessica said "Boy time sure flies."

"What do we have to do pop?" Flip asked Charlie.

"Don't worry." Jessica said as Charlie showed them the magic book. "The magic book has instructions on how we should set up for the coronation ceremony, which is due to take place in this castle."

"That's good." Flim Flam replied "But what about Scrappy?"

"They're off to rescue everyone else, who are currently imprisoned on Messick Island." Jessica replied. "He said that we should get started in preparing for the coronation ceremony now, and he'll get back to us after the rescue."

"Awesome." Yogi smiled. "We'd better get started now!"

"Right" Charlie nodded as he flipped through the pages until he got to what he was looking for. "So here's what we should do first..."

Back on Messick Island, all of the imprisoned characters, heroes and DC villains alike, are forced to kneel before Dr. Zin and Jenny.

"At last" Zin evilly grinned "I have won! I have finally defeated Dr. Quest and his gang!"

"The world is going to be ours father!" Jenny added.

"You have betrayed us Doc!" the Joker exclaimed "Why did I ever trust him?"

"Cause you're a clown" Cheetah remarked.

"The main continent is going to burn" Jenny sadistically smiled "The weak shall perish. In just 21 minutes, all of you will be dead!"

"We should have known better than to trust a double-crossing liar like you, Doctor Zin!" Grodd spat.

"Well, you all figured that out the hard way, and now it's too late now, especially thanks to your bumbling." Dr. Zin retorted.

Back in the sky, the Green Dragon was approaching Messick Island, where the source of blue electro-rays originated.

Through the open area of Dr. Zin's base, they can all see their friends being forced to kneel before Dr. Zin and Jenny.

"Oh, no" Daphne exclaimed. "Zin's got everybody now! We're too late!"

"Fear not, Shogun Daphne!" The Green Dragon said. "Allow my spirit to enter the blade of the Sword of Fate, and then you'll be ready for the fight."

"Like, hang on, everybody!" Shaggy shouted as he pulled out the Sword of Fate while Daphne held onto him as Scrappy stayed in Scooby's arms.

As Shaggy pulled out the sword, the dragon's spirit enters the blade, and after a flash of light, the six heroes started to descend to the ground.

"Like, we're right on schedule, guys!" Shaggy exclaimed as they landed towards the ground.

Back on the island, Dr. Zin and Jenny were grinning when they started to notice the container containing Shaggy, Scooby, Daphne and Scrappy's hearts were starting to shake violently.

"What's the meaning of this?" Dr. Zin asked.

"Look, up in the sky!" Stanley shouted as he looked up. "It's a bird!"

"No, it's a plane!" Henry shouted.

"No it's..." Robin was about to finish when he saw Superman in front of him. "...not Superman."

"No, everyone, look!" Velma shouted. "It's Shaggy, Scooby, Daphne, Scrappy, Mudsy and Boo!"

"Ow, my neck!" Fred exclaimed as he tried to look up.

"Huh?" Dr. Zin and Jenny questioned as they all look up.

Soon, the six remaining heroes landed on the ground, and at that moment, the container containing the four major hearts blew up.

"Ah!" Dr. Zin shouted as he and Jenny took cover.

As the smoke cleared, Zin and Jenny looked up, as Shaggy, Scooby and Daphne marched towards them with the Sword of Fate on hand and with their colours restored as their hearts returned. Similarly, Mudsy, Boo and Scrappy moved in together as they marched towards Jenny.

"Who dares to challenge me?" Zin asked as he got up with the Sword of Doom in hand.

"Like, here we go, guys." Shaggy said to Daphne and Scooby. "I only hope we're all prepared."

"I don't know." Scooby whimpered.

"Yeah, I've never felt so nervous before." Daphne added. "I mean, I never faced someone else holding another sword."

"Haha" Zin laughed. "What a joke! Prepare to join your friends!"

"Zoinks" Shaggy exclaimed as he, Scooby and Daphne covered their eyes.

With that, he charged towards the trio and swiped the Sword of Doom at them, only for it to be deflected by an unseen force, forcing him to retreat.

"What the...?" Zin asked as Jenny gasped.

At that same moment, Shaggy, Scooby, Daphne opened their eyes and realized that the sword was still shaking.

"If I'm not mistaken, Father, that's the Sword of Fate!" Jenny said.

"The Sword of Fate?!" Zin growled. "IMPOSSIBLE!"

"Oh yeah?" Daphne smirked as their confidence returned.

"Like, if you think that's impossible, Dr. Zin." Shaggy said. "Try flying back to your island base on a green dragon sometime."

"We may be fading, but we ain't gonna let you take our friends!" Scrappy raised his fists.

"Yeah" Mudsy added "You mess with April, you mess with the Funky Phantom!"

Boo showed his claws and hissed right at the villains.

Jenny responded by taking a combat pose as she faces Scrappy, Mudsy and Boo.

Similarly, her father prepared the Sword of Doom as he faces Shaggy, Daphne and Scooby.

"Like, let's do this, guys!" Shaggy said to his teammates confidently.

"Right" Scooby and Daphne both nodded in agreement while Scrappy, Mudsy and Boo gave their thumbs up.

Everyone watched Shaggy, Daphne and Scooby tightening their grip on the Sword of Fate with serious and "Game On!" looks on their faces, with Scooby also growling, as they face Dr. Zin, who narrowed his eyes, while Scrappy and Mudsy tightened their fists and Boo revealed his claws and hissing as they face Jenny.

The two parties soon charged towards each other for the final battle.

Meanwhile back in the Underworld, Shelly and Brenda finally arrived at Hades' place.

"Here we are" said Brenda.

"No turning back" Shelly added.

Meanwhile back in the Underworld, Shelly and Brenda finally arrived at Hades' place.

"Here we are" said Brenda.

"No turning back" Shelly added.

"Right" Brenda nodded as they entered the place.

It was quite a dark and scary place in Hades castle. It was crawling with scariness and paintings of dead evil people.

"Golly," said Brenda "It's like the Evil Hall of Fame in here."

"Well this is the Underworld" Shelly remarked "What did you expect?"

There was a sign that said "THIS WAY TO HADES", they followed it. They got into a room with a dark and scary looking guy sitting on a chair and looking at a fireplace.

"Um, excuse me?" Shelly gulped.

The guy turned around, it was none other than...Hades, lord of the dead.

"What can I do for you?" Hades asked with a devilish tone in his voice, spooking the girls.

"Aahh!" Brenda jumped into Shelly's arms.

"My name is Shelly" Shelly explained "And this is my friend, Brenda Chance. We're the latest deaths."

"I see" Hades said "So you're the new ones. So do tell me, have you had any sins, shattered hopes and dreams, heartbreaks or misdeeds."

"Why would you want to know?" Brenda shivered.

"Because...I am Lord of the Dead" Hades told them "And I will be the one who'll determine what I'll turn you two into. I may turn you two into Angels and send you to Heaven, I may turn you two into ghosts and keep you into the miserable world that ended you where you'll be feared and hated or I can turn you ladies into souls and you'll be stuck here. So tell me everything."

The two girls looked at each other and swallowed.

Author's Note:

Oh baby! It's the final battle that's about to begin! It's Great Danes, two meddling kids, the ghost of a 38 year old war soldier and the ghost of a cat vs. a mad scientist and his equally evil and malicious daughter. Looks like it's gonna get all Ninja Turtles in here (and I mean the 2003 4Kids series, not the 80's one).
