In Keystone City, Professor Zoom (aka, Reverse Flash) had come right before Scooby, the Flash and the guys.

"Professor Zoom!" Flash exclaimed.

"Do you fellas want to surrender the easy way or the hard way?" Professor Zoom smirked as he aims the vacuum nozzle at the heroes.

"Like I'd rather take the easy way out" Shaggy shivered in fear.

"So would I" Mudsy turned invisible.

"We're not going down without a fight!" Scrappy raised his fist.

"Scrappy's right" said Flash "We can't back out of this when the world is in danger of ending."

"Alright Zoom!" Scrappy raised his fist "You're messing with Scrappy-Doo here! We're not afraid of you, right Uncle Scooby?"

As Scrappy was making the comment, Shaggy saw a rock on the ground and took a deep breath as he picked it up.

"Like, let's hope this works." Shaggy thought to himself.

As Shaggy predicted, the rock hit the nozzle, causing the vacuum to break down.

"Yes!" He exclaimed as he pumped his arm in victory.

"Looks like you've gotten the short of the stick Zoom!" Flash pointed to Prof. Zoom.

"That's what you think, Flash" Professor Zoom snapped his fingers.

Just then, a copter was flying and someone jumped off and onto the ground. He landed so hard, you'd think there was an earthquake. It was none other than...

"GORILLA GRODD!" Everyone shouted.

"That's right." Gorilla Grodd smirked as he pulled out the vacuum. "Surrender right now!"

"Like, weren't you supposed to be watching me, Gorilla?" Shaggy asked as he swiftly picked up another rock and threw it towards the nozzle of Gorilla Grodd's vacuum.

"Yes, he does." Professor Zoom grinned. "Now, let's take these people's hearts!"

"Now hold it right there, Zoom." Grodd stopped him. "I've got a better idea."

"What?" Zoom barked.

"Instead of taking their hearts, why don't we use my mind control on them and make them do our bidding?" Gorilla Grodd asked.

"Not a bad idea," Zoom said. "Fire away Grodd!"

"Right" Grodd smirked before turning to face the heroes.

"Well, any ideas you got, Flash?" Blue Falcon asked.

Before Flash could answer, Grodd used his hypnotic powers on our heroes.

"You are now under my power!" he looked at them with his hypnotic eyes.

"Yes master." said the brainwashed protagonists.

However, Mudsy and Boo weren't hypnotized at all. They weren't affected.

"Heavens to Delaware" Mudsy remarked "Looks like it's up to us to sort this mess out, Boo."

"Meow" Boo nodded.

Mudsy and Boo vanished to formulate a plan. At that same time, Grodd and Zoom had been putting their plan into action.

"Now I am your master," Grodd looked into their brainwashed, swirly eyes "And you will obey my every command!"

"Yes master, Grodd" said the brainwashed heroes.

"You will surrender your hearts to me and Professor Zoom at once!" Grodd ordered.

"Yes master" Shaggy, Scooby, Scrappy and Flash braced their chests while the others stood still in a daze.

Zoom shot the vaccum nozzle on Shaggy's chest and his heart was sucked into a container, then he shot the nozzle on Scooby's chest and his heart was sucked into the same container and then Scrappy's heart was sucked out as well.

"Look at those hearts, Professor" Grodd sinisterly looked at the hearts "They're as good as ours."

"Now, to finally fulfill my lifelong goal" Zoom pointed the gun at Flash "Finally, the Flash will be no more."

At that moment, the two ghosts came up with a plan. With the two villains still occupied in sucking the hearts out of their comrades, the two ghosts entered the vacuum to possess it.

Just then, the vacuum came to life and started glowing.

"What the?" Zoom barked "What's the meaning of this?"

Just then, the vacuum started speaking in a creepy-sounding voice.

"Friends!" the voice spoke "What's the meaning of feeding me such disgusting-tasting hearts? I thought you all know that I'm on a heart-free diet!"

As Mudsy was making the speech, Boo was using his claws to scratch and sabotage the vacuum system.

"There must be something wrong with the vacuum." Grodd muttered.

"Yes." said Mudsy "The hearts you just fed me tastes really disgusting, repulsive, icky even. I don't think I can take it anymore."

Then, the vacuum started to shake violently.

The vacuum shook so fast, that Scooby, Scrappy and Shaggy's hearts were blown right out of the nozzle.

"The hearts!" Grodd shouted.

"I got them, don't worry!" Zoom flashed and caught all the hearts in a container.

Then, the ladder from the copter they were in landed down.

"Quick!" Zoom climbed on "Let's get outta here!"

"Right behind you Professor" Grodd climbed up the ladder as well.

Just then, the brainwashed characters snapped out of their brainwashing as well.

"Zoinks" said Shaggy "Like what happened?"

"Look!" Jabberjaw pointed to the copter.

"So long suckers!" Zoom waved the hearts from the copter.

The copter then started flying away.

"Jumping jellyfish" Biff exclaimed "Zoom and that ape guy got away!"

"And that's not all!" Scrappy said. "Our hearts are gone!"

"Say, where are Mudsy and Boo?" Augie noticed.

Back on the helicopter, Zoom and Grodd were glad that they still got the hearts.

"Haha, we finally triumphed over those losers!" Grodd laughed.

"And that's not all; we've got all of their hearts!" Zoom smirked. "I hope Cheetah is making progress on Paradise Island."

Just then, the entire helicopter started glowing.

"What the?" Grodd asked. "What on earth's wrong with the helicopter?"

"What is wrong is that I've just ate a stinking gorilla and an insane professor and my stomach is having an issue with that!" The helicopter, possessed by Mudsy, says as Boo uses his claws to sabotage the controls of the vehicle. "I thought you two will be kind enough to return our friends' hearts, but you left me with no choice."

At that moment, the helicopter started making funny noises and shake violently.

"Who's there?" Zoom asked angrily.

"Show yourself, I dare you!" Grodd snorted.

Just as Grodd made the remark, the container containing the hearts came to life.

Then, Mudsy turned visible as he held the container.

"Hello fellas." He smirked. "Thought I might come along in helping you with your scheme"

"So it was you all along!" Zoom said. "Wise guy, eh?"

Grodd then produced a ray gun and aimed it at the ghost as he added, "Hand me the container, right now, or you'll suffer the same fate as your friends down there."

"Make me." Mudsy smirked. "And besides, if I were you, I will pay attention on where I'm flying towards!"

"Huh?" Grodd and Zoom asked as they turned and looked.

As it turned out, the helicopter was running out of fuel, due to Boo sabotaging the fuel tank and causing it to sprung a leak, and worst of all, they were on a collision course with a skyscraper.

"Yikes!" Grodd exclaimed. "We're going to crash!"

"Yep" Mudsy smirked as Boo appeared. "We're not that cold-blooded, but your actions left us with no choice. So long"

With that, the two ghosts turned invisible with the container and flew out from the helicopter.

Back on the ground, the rest of the heroes were surprised when they say the helicopter crashing into a skyscraper and a container flying towards them.

"Zoinks" Shaggy exclaimed when he saw the container. "What's with the container?"

Just then, Mudsy and Boo reappeared.

"Mudsy!" Augie exclaimed "It's you!"

"Yep, it's us all right." Mudsy grinned.

Opening the container, he added, "And I believe these belong to you guys."

"Woo hoo!" Scrappy cheered "Our hearts!"

Soon, the heroes got their hearts back in their chests and looked towards the crash site.

In the crash site, Zoom and Grodd got out of the remains of the copter.

"Curses" Zoom crushed his fist "Foiled again!"

"No we're not!" Grodd grabbed Zoom "We must retreat back to HQ and recruit more villains! We'll get those hearts back and get Flash!"

Grodd put Zoom on his back and they went back to their lair. At that same time, Shaggy, Scooby and Scrappy put their hearts back into their chests.

"Ranks a rot Rudsy" said Scooby.

"Always a pleasure, a Scooby-Doo" Mudsy bowed.

"One question though," Flash said "How come you and Boo weren't affected by Grodds powers?"

"I'm a ghost Flash" Mudsy explained "Which means we in the afterlife aren't affected by brainwashing, unlike you mortals."

"Wowee wow wow" said Clamhead "That's pretty convienent."

"And reliable" Skip added.

"Looks like we've got two ghosts in handy." Flash remarked.

"Yeah" Dynomutt agreed.

"In the meantime, Flash, those two may be back later." Blue Falcon warned. "You better be prepared."

"Don't worry" said Flash "I will"

"Now we'd better go finish saving the world" said Biff "Where's the button?"

Captain Caveman took the button out of his fur "Me got it."

"Back to the forgotten land" Biff pressed the button.

A blue ball of lightning formed around our heroes and they were sent back to Boomerang Land.

Meanwhile back on Paradise Island, Wonder Woman finished telling the Teen Angels her plan.

You got to be kidding me." Shelly huffed as the girls helped her getting dressed in Wonder Woman's outfit. "I know this may be a key to help save the world, but this is ridiculous."

"Sorry, Shelly, but with your long black hair, you're the only one that can be disguised as me." Wonder Woman replied. "And besides, your heart is already gone."

"She's got a point there Shell" Bubbles said. "You've got nothing to lose."

"Fair enough." Shelly nodded.

Once Wonder Woman finished wearing Shelly's outfit, the girls wasted no time making their way to the address Cheetah and Jenny provided them in the video message. It was in some sort of cave in the Paradise Island jungle.

"There it is Teen Angels!" Wonder Woman said "The rendezvous point. Now Shelly, you proceed in and pose as me."

"Got it" Shelly said.

"Once you give me the signal, I'll rescue Steve and the rest of you apprehend them." Wonder Woman informed them "Got it?"

"Got it" said the Teen Angels.

Shelly walked into the cave inside of it; the two villains were waiting impatiently.

"What's holding her up?" Jenny wondered.

Just then, Shelly, disguised as Wonder Woman, arrived.

"About time you showed up." Cheetah said.

"We were getting impatient" Cheetah said.

"Whatever" Shelly put a hand on her hip "I'm here now I can give you what you want."

Hiding behind a nearby door, Daphne saw Shelly giving the signal in the form of placing her hand on her hip and turned to give Wonder Woman and the rest of the girls' thumbs up.

"Excellent" Wonder Woman nodded as she and the other girls entered. "Now you girls keep those two occupied while I go rescue Steve."

"Okay." The rest of the girls nodded before they stealthily approach the door.

"Alright missy" Cheetah pointed a vaccum like gun at Shelly "Get ready to be heartless!"

"I'm ready baby" Shelly said bodly.

Jenny smirked as Cheetah flipped the switch. The vacuum was activated and made its attempt to get Shelly's heart out.

However, as the seconds went by, nothing emerged from Shelly, who now had a smirk on her face.

"What's the matter with the vacuum?" Jenny asked. "Her heart should be out by now."

"I don't know." Cheetah replied. "I hope your father has gotten all of the vacuum guns checked before distributing them to all of us, because chances are that this one may be defective."

"My father is a mastermind!" Jenny barked "Of course he double checked them! He double checked them twice!"

Cheetah then looked at Shelly real hard "Wait a minute. You're not Wonder Woman! You're some chick dressed up like her!"

"That's right." Shelly smirked. "Took an ugly-looking cheetah like you quite some time to figure it out"

At that moment, Cheetah growled as she activated her claws. "Don't you ever talk to me like that?"

"Now tell us, pretty-face." Jenny said. "Where is Wonder Woman?"

"Before she tells you where she is, you will have to deal with us girls, first!" A voice suddenly shouted.

"What?" Cheetah asked. "Who's there?"

"Show yourself, I dare you!" Jenny shouted.

"Hello, Jenny Zin." The voice said again, and as the two villains and Shelly turned and looked, Daphne and the rest of the girls approaches them. "I'm sure you still remember me from that brief encounter when your father attempted to free you from the mechanical dragon you've trapped yourself in."

"Yes!" Jenny barked "And I've had some time to contemplate my revenge!"

She then produced another vacuum gun and aimed it at Daphne.

"Prepare to say goodbye to your heart, Daphne!" She smirked.

However, just as she pulls the trigger, Daphne grabbed a rock from her purse and threw it towards the nozzle.

"What?" Jenny exclaimed as the rock hits the nozzle.

"Looks like you're all rocked out, Jenny!" Bubbles giggled.

"No more games Cheetah!" Wonder Woman snapped at Cheetah "Where's Steve?"

"I'll tell you where he is if you surrender your heart" Cheetah smugly smiled.

"Never!" Wonder Woman snapped.

"Very well" Cheetah pressed a button on her remote "I guess I have no choice."

A hatch opened up from underneath the floor and there was Steve, trapped to a chair.

"Steve" she gasped.

"Teen Angels" Daphne said to the other girls "Attack!"

But before they could, Jenny pressed another button and the girls got trapped as well.

"What's going on?" April gasped "We're trapped."

"You think Stewart?" Shelly asked her sarcastically.

Cheetah showed her claws "The choice is yours princess. Either you surrender or I will claw your lover boy to death and I'll make you watch."

"Steve or the heart" Jenny sadistically grinned.

"Very well." Wonder Woman said as she willingly steps in front of Cheetah.

"Say farewell to your heart, princess." Cheetah smirked as she pulled the trigger.

"No!" The girls exclaimed as they watched Cheetah's vacuum gun taking Wonder Woman's heart.

"That does it." Daphne said as she used a pick to get herself free from the chair.

"Daphne, what are you doing?" Dee Dee asked.

Without answering, Daphne grabbed another rock from her purse and threw it towards Cheetah's vacuum gun, knocking it from her hand and smashing it into pieces before it could fully suck in Wonder Woman's heart.

"You fool" Jenny exclaimed as she watched the vacuum gun smashed by Daphne's rock. "Do you know how much it costs my father to have these weapons replaced?"

"Looks like daddy will have to keep spending!" Daphne exclaimed.

"That does it!" Cheetah showed her claws "I'm definitely killing you Blake!"

Cheetah walked to Daphne and showed her razor sharp claws and was about to claw her to death.

At that same time, Jenny picked up Wonder Woman's heart, which fell onto the floor into a jar.

Just then, a lasso appeared out from nowhere and pulled Cheetah back.

"Not today, Cheetah." Wonder Woman put her hands on her hips.

"Arrgh" Cheetah exclaimed as she struggles to break free from the lasso, only for it to get tighter.

Seeing that Jenny has gotten her heart, Wonder Woman, using the tied-up Cheetah as a weight, pulled her closer towards her and causing her to knock over Jenny in the process.

"Watch where you're going, you clumsy fool!" Jenny growled at Cheetah as she struggles to get up.

"I will be if that meddling princess hasn't tied me up!" Cheetah retorted as she continues her efforts to break free.

Taking advantage of the situation, Daphne walked over to take the jar, opened it and took out the heart.

"Here's your heart, Wonder Woman!" She says as she tossed the heart towards Wonder Woman.

Wonder Woman jumped into the air, allowing her heart to re-enter her chest.

"There!" She smiled before performing a few rope tricks, and within seconds, both villains were tied up.

Then, the others were freed from their chairs.

"Looks like you've got the short end of the stick, eh pretty kitty?" Shelly made a smug face.

Wonder Woman ran over to Steve "Steve! Oh thank goodness!"

However, there was something that didn't seem right about Steve.

"Steve?" Wonder Woman asked when she saw her love. "Are you alright?"

Just then, something happened. Steve wasn't Steve at all.

"You're not Steve!" Wonder Woman said as the girls looked on with shock.

"Jokes on you princess" Jenny made a smug smile "That's not your Prince Charming! That's just an android we programmed to trick you into surrendering yourself!"

"Who's got the short end of the stick now?" Cheetah gloated as she used her claws to untie the lasso.

"By the way" said Jenny "That's not just any android, it's a powerful bomb set to go off any moment and blow up the entire lair with you and those meddling Angels in it."

Jenny took out a remote and the whole cave started to shake and rocks started to fall down.

Jenny and Cheetah ran outside and escaped in a copter. Back inside, the whole cave was about to self-destruct.

"Golly!" Brenda screamed "We've gotta get outta here!"

"Brenda," said Dee Dee "For once, you said something useful!"

"Let's go!" Wonder Woman ordered, and the girls all quickly took off.

A few seconds after they made it out of the jungle, the cave blew up.

"Jeepers" Daphne stopped to catch her breath "That was a close one."

"Yeah," said Shelly "I could've gotten a blister."

"Well at least you're safe princess." Dee Dee said to Wonder Woman.

"But not for long" April reminded her.

"Not to worry, girls." Wonder Woman said. "I'm always ready for the likes of Cheetah and Jennifer Zin."

"Alright" Taffy said. "Now, I suppose we should return to Boomerland, eh?"

"Right" Shelly nodded before taking out the bottom.

After bidding farewell to the Amazon princess, the girls were teleported back to Boomerland, arriving at the same time as Shaggy's group.
