Finally, Scooby and Mudsy's team were landing right on Messick Island.
"Attention passengers" said Scrappy "We are descending right into Messick Island! An island inhabited by wild animals and some sort of evil scientist. We all know you have a lot of choices, so thank you for flying Air Green Dragon."
"Looks like we've made it already, Scooby-Doo" Mudsy told Scooby.
"Yeah" said Scooby "Now we can go stop those evil villains and save our friends!"
"So," said Daphne "Where are April and the others? They were supposed to be here."
Scrappy took a mini telescope out of his tag and saw the Egnima Machine "Uncle Scooby! Look up in the sky!"
"Like, it's the Enigma Machine." Shaggy exclaimed when he recognized the van. "They must have held off Luthor and his allies."
Soon, the Enigma Machine landed in front of them.
"Shaggy, Scooby, Daphne, Scrappy, Mudsy, Boo!" Skip said as they got off the Enigma Machine.
"Guys!" Scrappy said. "Did you managed to hold off Luthor and his baddie pals?"
"We sure did." Brad said.
"Yeah, after using our lasers to sabotage the war jet while BF and pals did the rest." Augie nodded. "They must be having a good splash right now."
"That's good." Daphne said. "Now we've got to get in and rescue our friends!"
"I'm afraid it's not going to be easy, lady." A voice suddenly said.
Everyone turned towards where the voice came from. It was Captain Planet and the Planeteers.
"Oh, not you again!" Mudsy exclaimed.
"That's right." Captain Planet sneered. "You meddling kids have meddled once too often!"
"Enough cheesy puns you creeps!" Brad told them "What've you done with my son?"
"We have done nothing" said Linka "But we are going to zap you like little flies and finish you off once and for all!"
It was then that they heard fighting from the inside of the base.
"Sounds like we've got a prison riot going on inside." Augie remarked. "Our friends must be fighting Zin and his allies!"
"We'd better help out." Skip said. "And show those creeps how mad we can be for them killing the love of our lives!"
"I'm with you, man." Biff nodded. "Those villains will wish they were never born!"
"Scooby, Shaggy, Daphne!" Brad said "You and those other three guys in your group fight off these guys, we'll find Dr. Zin's base and free the others!"
"Don't worry Brad!" Daphne said "We'll take care of these guys!"
"Come on," said Bubbles "We've gotta save our friends!"
"Right." Skip nodded before his group, along with the original Mystery Inc., Blue Falcon, Dynomutt, Birdman, Jana and Space Ghost all raced into the base while Shaggy, Scooby, Daphne, Scrappy, Mudsy, Boo and the Green Dragon faced Captain Planet and the Planeteers.
After the split-up, Shaggy, Scooby, Daphne, Scrappy, Mudsy, Boo and the dragon face Captain Planet and the Planeteers.
"Time to settle this once and for all!" Planet said. "You kids meddled once too often!"
"Like, bring it on!" Shaggy replied evenly.
"You're not scaring us this time, Planet!" Mudsy added.
Mai-Ti and Daphne were having an epic battling.
"Meow!" Boo added.
"You will come back with us and we will get that brush back!" Wheeler said "Fire!"
Wheeler shot fire from his power ring and a whole circle of fire surrounded our heroes.
"Oh no!" Mudsy shouted "It's ha-ha-ha-happening again!"
The whole fire reminded Mudsy of the attack the British did on his family's home before they got killed.
"Like, not if I can help it!" Shaggy said as he took out the sword.
Its power allowed Shaggy to slice the blade through the flames and put the fire out, while the Green Dragon huffed and blew out the flames.
"Jeepers Shaggy," said Daphne "You really are a natural with that thing."
"Yep" said Shaggy "I've got still got it!"
"Alright Captain Planet!" Scooby growled "You won't be taking us tonight!"
"Yeah" Shaggy said "Now that we've got the Sword of Fate!"
"Plus, you're talking to Scrappy-Doo!" Scrappy said "The newest samurai!"
"And the Funky Phantom!" Mudsy added.
"Meow!" Boo boasted.
"You kids leave me with no choice!" Captain Planet responded. "How about returning to the Turner place and settle this once and for all?"
"It's a date!" Daphne bodly said.
Back inside Dr. Zin's base, a massive battle between the heroes and the villains was taking place.
Our heroes were battling their foes with all they had. So many villains were there including; Dr. Zin, Jenny, the Joker, Catwoman, Gorilla Grodd, Professor Zoom, Sinistro Corps, Black Manta and Orm. As well as Dr. Zin's agents.
"Alright Crystal," said Amber "Let's do this!"
"Right" Crystal said.
They both touched their necklaces and transformed into their alien forms.
It was then that Augie's group entered the fray after Skip and Biff knocked down several agents that tried to block their way.
Seeing Orm, the Black Manta and the Sinistro Corps, Skip and Biff turned to each other.
"Let's get those losers for murdering our loves, man!" Skip said, and Biff can see that his eyes were on fire with vengeance.
"You've got it, man!" Biff replied evenly as he shook Skips hand. "They're going to wish that they were never born!"
"Right." Skip nodded before producing a large hand with the power of his ring and handpicked the three villains responsible for Shelly and Brenda's deaths while their teammates joined the fight in fighting the other villains.
Just then, Skip noticed something; it was a portal leading back to the DC world.
"This is for Brenda and Shelly!" He and Biff both said at the same time.
Skip used the large hand from his ring to throw a fastball of them into the portal and Biff quickly shut it down, so they wouldn't get back.
"Alright!" Biff and Skip high fived.
"Now let's go kick us some villain bahookie!" Skip said "Only for Brenda!"
"And for Shelly!" Biff went back to the battle.
The battle kept continuing. All of our heroes were fighting against the antagonists in this epic battle.
Back at the castle, Charlie, Jessica and the animals were lost looking for the tallest tower.
"Are you sure you know where we are Mr. Chan?" Boo-Boo asked.
"Actually I'm not sure" he said "Maybe if we found some signs, we could find out where the tower is."
"But the signs are all faded" Dixie pointed to the sign. "What're we going to do?"
"Uh, meeces? Charlie?" Mr. Jinks collapsed to the ground "I think I'm getting lighter and weaker."
"Oh no" said Jessica "We're running out of time. According to my calculations, we have only 22 minutes left before we all die!"
"Then there's no time" said Charlie "We must find another way to get to the tower. Yogi, Boo Boo, you and the mice stay here and look after Mr. Jinks. Jessica, Ruff, Reddy, you guys come with me!"
"Right" Jessica, Ruff and Reddy said at the same time.
Meanwhile back downstairs, the kids were still fading and waiting for the adults to return, but they hadn't.
"I'm worried, guys" Scooter said "What if daddy doesn't come back?"
"Pop is the bravest, smartest adult I know" Flip told his brother "He'll never give up on us."
"I'm just worried" Scooter started to cry "What if he doesn't come back and we never see Henry, Stanley, Suzie, Alan, Tom or Anne again?"
"And I'll probably never see my daddy again either" Cavey Jr started to cry as well "I want my daddy and aunties!"
Mimi tried to hold back her tears "Don't you dare cry Scooter Ch-ch-ch-Chaaaannn!"
Mimi hugged her brother and started to cry as well.
"Well, I guess this is it, Nancy." Flim Flam turned to Nancy. "This could be our last time together."
"Yeah." Nancy sighed as she decided to share an embrace with Flim Flam.
"This is it" Flim-Flam started to cry "And it's worse that we can't spend it with our families."
Flim Flam nodded as they shared a long embrace.
Chu-Chu was vanishing more and more, until the unthinkable happened...he disappeared into thin air.
Mimi gasped "Chu-Chu! No!"
Back upstairs, Charlie, Jessic, Ruff and Reddy were racing up the stairs with what remaining strength they have left.
"Guys" Jessica huffed "I can't go on anymore. I'm fading."
"Huh?" The males turned around and saw Jessica all weak and vanishing more and more.
"Say, I see the door up there." Ruff exclaimed. "We're almost there!"
"You guys go on!" Jessica said.
Immediately, the trio made their way to the top of the stairs, pulled the door open and entered the room.
Looking around, they soon found another copy of the magic book, as well as what they were looking for.
"There it is, guys!" Charlie said! "The crowns!"
"Awesome!" Reddy said as they spotted the two crowns, one with a large "H" and the other with a large "B" inscribed on the gold.
As soon as Ruff and Reddy walked over and touched the crowns, they felt a sudden surge in strength and a restoration in colour.
"Say, I'm feeling more colourful all in a sudden!" Ruff remarked.
"Same here." Charlie said before taking the magic book and opened it and flipped through the pages until he found what he was looking for.
"According to the magic book, it says that once the heirs to the throne of Boomerland touches the crowns, all characters will have their colours and strength restored temporarily for an extra hour." He read. "If you don't get crowned in the coronation ceremony within the extra hour, we'll all vanish for good!"
"That means we've now got one hour and 21 minutes to go!" Reddy said. "We'd better inform Scrappy and have him arrange the ceremony soon!"
