In Keystone City, the guys and Flash were trying to figure out a way to find out who could be trying to get Flash.

"Okay guys," said Biff "As we've established, Dr. Zin had found an ally here and he plans to use him to steal Flash's heart."

"And to make his ally's heart double in size" Scooby added.

"So what particular villain do you fight most often Flash?" Jabberjaw asked.

"Besides Professor Zoom, there's Gorilla Grodd, who I fought the most often." Flash replied.

"Like, and he's got mind control abilities." Shaggy added.

"Mind control?" Mudsy gasped "Meaning b-b-brainwash us?"

"Yep" said Shaggy.

"There's no way I'm doing it" Mudsy said "Not me!"

"Biff, Shelly, Bubbles and I got brainwashed once, boy you do not wanna know what they made us do" said Clamhead.

"What happened?" Augie asked.

"Oh we got brainwashed by some power mad soceress." Biff explained "But that's another story. Right now, we have to deal with Gorilla Grodd and Professor Zoom."

"Yeah. If I know Dr. Zin, I'm sure he'll be happy to have a mind-controlling gorilla on his team." Flash remarked.

"Like, I'll even bet that he must be having a video call with Dr. Zin and Professor Zoom right now." Shaggy added.

"We'd better find him and stop him before he finds us before he brainwashes us" said Scooby.

"Yeah" Scrappy picked up Scooby "So where should we start?"

"If you want to start with Gorilla Grodd, we'll have to travel to Gorilla City over in Africa." Flash replied. "That's his hometown."

"But there's no time to go to Africa" Biff said "Maybe for you, but some of us don't have much time to live."

"I guess we'll have to find Professor Zoom then" said Flash.

"But where do you suppose we find him?" Captain Caveman asked.

"Like, I think we may have the answer, gang." Shaggy said urgently as he pointed towards a speeding yellow figure.

The figure stopped in his tracks right in front of our heroes.

"Hello Flash" said the figure "I heard you were just talking about me!"

"Professor Zoom!" Scooby and the others shouted.

"Yes, and I'm warning you all to surrender right now, or I'll use this device on you!" The villain smirked before producing a vacuum-like ray gun.

"Oh no" everyone gasped.

"Say goodbye" Professor Zoom pulled the trigger on the gun.

A nozzle came out of the gun and started zooming fast towards Scooby and Flash.

Meanwhile miles away from the mainland on Paradise Island, Wonder Woman was getting the girls suited up for their big battle.

"There you go, girls." Wonder Woman said. "That's more like it."

"Alright" Shelly looked at herself in the mirror "Really shows off my curves."

Shelly kept making poses while looking at herself in the mirror.

"Not bad." Daphne nodded as she took out a mirror and looked at herself, nodding at the purple skirt she's wearing.

Yeah," Brenda looked at her outfit "This makes look even curvier."

"Right. Now the main thing for you girls is to be prepared for the hurricane when it strikes." Wonder Woman nodded.

"Hurricane?" Bubbles gasped "What hurricane?"

"I think she means Cheetah and Jenny Zin, Bubbles." Taffy said.

"I knew that" Bubbles shrugged.

"No you didn't" Shelly rolled her eyes.

Just then, a flying droid flew down to our heroines and was carrying some sort of screen.

"What the heck is that?" Shelly looked at the screen.

"Why don't we take a look?" Wonder Woman suggested.

The girls took the screen from the robot which zoomed out of the palace. Just then, Cheetah and Jenny's faces came up on the screen.

"Zowie!" Taffy exclaimed "Jenny and Cheetah!"

"Speak of the devil" April said.

"We heard that, April." Jenny replied. "You girls are lucky that we're far away right now, or my friend Cheetah here will scar you for calling us devils!"

"And let me guess, you two are sending this message to warn us, eh?" Dee-Dee said.

"Hello Wonder Woman" Cheetah made a smug smile "I'll bet you are probably wondering why we are sending you this message. Probably to warn you right? Think again!"

"What a surprise" Daphne remarked.

"Wonder Woman, I got a surprise for you!" Cheetah turned the camera to see Jenny holding Steve Trevor hostage.

"Steve!" Wonder Woman gasped.

"That's right." Cheetah smirked. "You can surrender right now and give up your heart, or you'll never see Steve again!"

"Make up your mind, Wonder Woman" Jenny sadistically smiled "If you want your boyfriend back, you will surrender yourself and your heart."

"Jeepers" said Brenda.

"I couldn't have said it better myself" Daphne remarked.

The girls looked at Wonder Woman, not sure what decision will she make.

"You have to make up your mind, Wonder Woman" said Dee Dee.

"Yeah," Brenda added "You can surrender your heart or lose the man you love forever."

"The choice is yours, Princess" Cheetah sadistically grinned.

There was some silence as the girls and the two villains through the video watched Wonder Woman making a hard decision.

Would she surrender herself? Or lose the love of her life? Finally, she came to a choice.

She breathed in deeply then spoke "I'll do it!"

The girls gasped.

"Very well." Cheetah smiled sinisterly. "At last, she realized."

"Wonder Woman" Shelly said "You're actually willing to give up your heart and yourself for some guy?"

"Why would you do that?" Taffy asked.

"Now listen carefully, princess." Jenny instructed. "This is what we what you and the girls to do."

"What do you want Jenny?" Dee Dee folded her arms.

"At the bottom of the screen, you'll see an address." Cheetah said. "That is where we are, and where you and the girls are going."

"And don't try to get someone else to come with you or enlist the help of another hero, because if you do, then we'll find out and things won't get pretty." Jenny warned.

"And you'd better right this down fast" Cheetah added "This message will self destruct in 20 seconds"

"Quick!" Brenda told Daphne "Write the address"

Luckily, Daphne was a speed reader and she wrote down the address fast.

As soon as she finished, they all backed away from the droid as it exploded into smithereens .

"There." Daphne said as she looked at the address she just wrote down. "Now what?"

"We have to follow her orders" Wonder Woman sighed.

"What?" The others asked.

"Are you nuts?" Shelly put her hands on her hips "You're gonna surrender yourself to your arch enemy just for some guy?"

"Yeah" Daphne added "I can't believe you'd put yourself and your heart and probably mine at risk just for one individual!"

"Why on earth would you do such a thing?" Dee Dee asked Wonder Woman.

"No, no, girls." Wonder Woman said. "It's actually part of a plan I have in mind."

"A plan?" Bubbles asked "What kind of plan?"

"It's a plan that will allow us to rescue Steve while keeping our hearts." Wonder Woman explained. "Now listen closely."

The girls leaned in.

"We're listening." They said at the same time.

"Good." Wonder Woman nodded. "So here's the plan..."
