Discovering he was immune to Duu's telekinetic powers gave Wakko an edge in the fight. Duu might have a more muscular tone, but he wasn't as strong as he appeared. Stripped of his advantage, Duu had a harder time keeping Wakko down. Wakko was confident he could wear out Duu, then go help Dot and Yakko.

Duu was losing his patience. It was bad enough that he could no longer grab the wild child with his powers. Now he was zipping around him, making him dizzy and trying to tire him out. If only he could get his hand on him. His eyes caught something in the corner and he smiled.

Formulating a plan, he began to lead Wakko to a certain place. He let the boy pounce on him. He knocked him off with a paw. He tackled him and bit him on his tail. Wakko retaliated by biting his front paw. A blur of bristling fur rolled across the floor, a cloud of dust kicking up all around them.

Duu pressed his back against a large shelf. He lowered his ears and let out a soft whimper. Wakko smirked at this, believing he had bested the deranged toon. He arched his back, moving his tail back and forth. Then he leaped into the air.

He realized his mistake too late.

Duu jumped out of the way. Wakko, unable to stop himself, slammed against the shelf. It wobbled back and forth before coming crashing down on him. He barely heard his siblings scream his name as the heavy metallic shelf crushed down onto him. Pain wracked through his body.

Duu moved around a barrel. He sneered at the fallen boy. Wakko managed to crawl out of the underneath of the shelf. He rubbed his forehead and let out a soft groan.

"What just hit me?" He muttered.

"This did."

Wakko looked up just in time to see Duu kick over a barrel with a small hole in it. Green liquid spilled all over the floor. The fluid rushed towards Wakko and hit him on his feet. In an instant, his eyes were open, tears crawling out of the corner of his eyes.

The scream that came out of his lips echoed throughout the building, sounding like something out of a horror movie. Dot and Yakko could see what was going on. The glass made it look wobbly, but it didn't take a genius to know what happened.

The Thinner now covering the floor around Wakko burned into his paws. He screamed again as he took a step back before falling down. Now his arms and hands touched the stuff. More painful screams as he crawled away from the liquid. Blood dripping down from the open sores from his body, Wakko tried to get up. The pain was too much and he collapsed.

Duu walked up to the whimpering and shaking child, careful to avoid the Thinner himself. He took the boy's mallet again. Oh how he loved to use his enemies' weapons against them. Wakko attempted to stand, but the pain prevented him from getting out of the way. The mallet hit him on the head and knocked him out.

"Wakko!" Dot cried in horror, seeing her brother passed out on the ground, bloodied.

Duu stood over the boy, pondering if he should finish him off. He turned his head to the remaining siblings. No, they needed to be dealt with first. He went over the control panel. Giving an evil smile to the pair, he pressed a button below the levers.

A pipe the Warners didn't notice until now began to quiver. They heard a bubbly sound. Something was moving through the pipe. Dot was the first one to notice what was happening.

"He's raising this stuff!" Even though she didn't know what it was, she knew it wasn't safe. She clung to her brother's tail tighter. "Pull us up!"

"I'm trying!" Yakko struggled with all his might to pull them up. He couldn't get a grip and his feet kept slipping down the side. "I can't get a foothold!"

The Thinner below them was rising up rapidly. Each second, it inched closer to them. Yakko tried to hang on, but he didn't know how long he'd be able to do this. With a burst of strength, he pulled himself up and almost made it over the edge.

Then something happened that made his blood run cold and the fur on the back of his neck to stand on end. Duu, using his transformation power which he hadn't used until now, moved in front of him. There, he floated, just inches away.

"Hello there." His calm voice said.

"No..." Yakko whispered. His heart raced inside his chest. White pupils were now so large they nearly hid his black sclera completely.

Duu's face contorted into a twisted smile. "Shapeshifting takes a lot of effort...but it's so worth it to do this!" He raised a foot and stomped onto Yakko's hands. He loved hearing the boy cry in pain. Duu stomped on his hands again and this time twisted his foot on them to cause more pain. "I told you this will be your grave!"

"Yakko!" Dot cried. "Don't let go!"

Yakko tried to hang on. The pain was making it hard to do so. It got worse when Duu lowered himself down and showed his claws to him. Yakko's eyes widened, realizing what he was fully intending on doing. With a quick motion, the hands came down onto him. The claws dug into his arms. Yakko stifled a cry and tried to hold back tears as Duu slowly moved his arms back, producing long bloody cuts on his arms.

Then, Duu made the final move. He lifted up his foot and kicked Yakko in the face. The force was enough to dislodge Yakko's fingers from the edge of the vat. He and Dot screamed and Duu laughed as they fell towards the Thinner below.

Suddenly, Yakko and Dot hit against something soft and fluffy. Though dazed and confused, they held on tightly.

Duu couldn't hide his feelings of shock at what happened. "When did a giant chicken get in here?!"

Chicken Boo let out a cluck in response. His wings were spread out, giving him some sense of balance. He moved his legs as fast as he could, his feet pounding against the side of the vat. He ran around the vat, getting closer and closer to the top. His wings struck Duu and pushed him back as Chicken Boo got over the edge. He swooped down to the floor, the two Warners still holding onto his back.

"I never thought I'd be so glad to see you, Boo." Yakko said, immensely relieved.

Chicken Boo clucked at him, giving the best smile he could.

"Where did you come from?" Dot asked.

The large chicken pointed towards the door. It had been opened and they could see movement just outside of it. They realized this was the loud crash he had heard.

Duu, back in his original form and on the ground, stormed towards Yakko and Dot. He was hoping to get them from behind. He didn't get far. Swooping all around him were birds. Three pidgeons to be exact.

"Come on boys! Let's show this guy what we Goodfeathers can do!"

Duu grunted in pain as the pidgeons flew all around him, pecking at his arms and face. He swatted at them. They moved out of the way, avoiding getting it. Pesto, Bobby, and Squit began to circle his head, keeping him at bay.

"Hold still, you bloated pidgeons!" Duu shouted. He was greeted with Pesto's face against his.

"What's that? You want a piece of me? Do I amuse you?" Pesto gave Duu the stink eye. When Duu nodded his head, Pesto's feathers fluffled up. "That's it!"

He flew at Duu's face. He held his wings against his cheeks while his talons and beak cut into Duu's face. Bobby and Squit joined him, pecking at his ears and ripping off fur.

As the Goodfeathers kept Duu busy, Dot and Yakko reached Wakko's side. He was still out cold. Yakko ran his fingers through his brother's head fur. He checked his feet and arms. The sores looked bad, but they weren't very deep. Gently, he picked him up and set him on Chicken Boo's back.

"Get him to Hello Nurse." Yakko ordered.

Giving a loud cluck, Chicken Boo ran out of the building.

Dot looked up at Yakko. "Do you think he will be okay?"

Yakko looked down at her. "I'm sure he will. He's tough." He put a hand on her shoulder. "So don't you worry."

Dot smiled, but then noticed something off to the side. Buttons and Mindy were walking down the aisle. She didn't bother asking why they were there. As Mindy got closer, Buttons growled and ran off, presumably to attack Duu.

Mindy was holding something in her hand. "Pretty picture." The girl babbled as she moved closer to Dot.

Dot knelt down and held out her hand. "May I please have the picture, Mindy?"

"Okay, lady." Mindy giggled as she handed Dot the picture.

Dot and Yakko examined it. It wasn't just a picture. It was an animation cel of some kind. It looked old and dusty. Dirt covered it almost completely. Enough of the dirt was removed for them to see it was Duu on the cel.

Where had Mindy gotten this? They guessed it was from around here somewhere. The little kid probably found it laying around and picked it up because she liked it. It seemed like something she would do.

At first, it seemed like it was going to be useless and they would have thrown it away. But something drew them to this particular animation cel. There was something about it that stuck in their mind. They couldn't explain it. It was almost like their minds felt this cel could help them somehow. In what way, they weren't sure. Could it help stop Duu? Or would it just help them understand his origins?

Attached to the picture was a note. It was largely scribble, but some of it was readable. Yakko picked it up and peered at it.

"Property of...I can't read the name." Yakko turned it every which way. But nothing helped. "I think this might be from a rival company. Warner Studios has a few of those."

"Do you think Duu is just a rip off of us?" Dot asked.

"It would explain his sour personality." Yakko muttered, remembering the pain Duu put him through. "A toon created with the intent to steal. Not a good combination. No wonder he hates humans."

Dot got an idea. She looked over at the vat of Thinner. She recalled the words she heard spoken before. Original animation cels were important to toons. She only remembered bits of why, but something about how they were required for a toon to have a physical form. If they were to get the cel tossed into the Thinner, then maybe they could...

"Come on, Yakko!" She grabbed his hand and ran before he could say a word.

After a scream of frustration, Duu swatted at the Goodfeathers. He managed to backhand them and they smashed against the ground. They lay there dazed as Duu walked over to them. He was about to smash them with his foot when a frying pan out of nowhere crushed into his head. His body flinging away, he could barely here his attacker's snarky comment.

"Now that's payback!" Slappy twirled her frying pan in her hand and walked over to the downed Duu. "Hey, you remind me...of a very young Amon."

She was flung back by Duu's powers. He got back to his feet. He took a step towards the squirrel, but stopped. He couldn't worry about the little details right now. He looked up and saw a few more Animaniacs characters coming in. He narrowed his eyes. This would make his job even harder. He had to get away, somehow.

He looked over and saw Yakko and Dot holding something. His eyes grew big. No, they couldn't have found it, could they? No, they had to be stopped. He tried to get at them, but Buttons had charged him before he could get a step close to the Warner siblings.

"You mangy mutt!" Duu struck the dog down with his claws. "Get out of my way!"

Duu was pushed into the ground. Something heavy stood on his back. He craned his head in time to see another dog standing there. This dog, who turned out to be Runt, stared at him with a goofy smile for a second before he let his inner dog kick in. Fangs sank into Duu's back.

As Duu struggled, he felt needle sharp claws scratch at his arms. Rita, her fur bristling, clung to his arm. The two weighed him down and continued to maul him. Buttons, having recovered, joined in. He chewed on Duu's tail, chomping on it like it was one of his bones back home.

Finally, unable to take it anymore, Duu glowed brightly and threw the three animals off of him. He stared at them, fuming. How dare they interrupt him... After he takes over, he'd make sure they pay dearly for their interference. Ungrateful... They should be thanking him. What he was doing would have benefited them, but they chose to defy him. What a way to repay him for what he saw as noble deeds.

He turned his eyes to Yakko. The boy had to be the reason behind this. Yes, it was all his fault. If he hadn't told anyone about the attacks, if he hadn't given anything, not so much as a clue, then everything would have come into fruition. Power over the studios would have fallen into his hands. He would have been a hero.

But instead, the Animaniacs, so ungrateful and misunderstanding of his goals, have come to spit on his face pretty much. Yakko had told enough that they were able to put the pieces together, and came to help Yakko and stop Duu himself. Yakko stole his victory away from him. He would make sure he would never be able to do it again. He would make sure he would never have a chance to destroy him.

As Chicken Boo lunged for him, Duu turned into his black-colored shapeshifting form. He moved out of the way. The chicken crashed into the ground and went into a confused daze from the force of the impact. Duu zigzagged around until he reached Yakko.

Just as the boy was about to throw the animation cel into the vat, he snagged the boy by the scruff of his neck and yanked back. He knocked Dot away, slamming her back against the side of the vat. Yakko called out for Dot and tried to strike at Duu. It was all in vain; he couldn't do much being held like this.

Duu raised himself a few feet in the air. He held Yakko out in front of him. He watched as the boy tried to hit him. He smirked at his pathetic attempts to hurt him. Yakko tried to pry the hands off. Duu's grip was like a vice.

"You are going to pay for this..." Duu whispered harshly into his ear. He pressed a finger against Yakko's nose, crunching it againts his face. "I was going to give you a quick death. But now I think I rather kill you as slowly as possible, so you will suffer."

Yakko snapped his jaws at Duu. His teeth crashed against each other against air. Duu had moved his hand away. "I am not afraid of you anymore..."

Duu snarled as a smile spread across his face. "Then I will make you fear me again..."
