Chapter 13: Ultimate Mega Cat
As they reached to the end of the hallway, they spotted an elevator which leads them to Simian's sector. They got inside and Mega Cat push the button that will take them all the way to the top.
"Alright everyone get ready whatever Simian and brown's project is it's probably big and nasty." Proto Cat said
*Snicker* big and nasty." Mega Cat snickered
*Sigh* can we please be matured." Proto Cat said facepalming
"Sorry."
When they reached to the top, they got out of the elevator. "So where are they?" Mega-Dan asked.
"We are up here." Everybody looked up and see Dr. Simian and Dr. Brown standing on top of a giant shadowing figure.
"Well now greetings to Watterson's." Dr. Simian said smirking with her arms cross.
"Simian." Mega Cat said
"First, I want to congratulate you guys for making this far." Dr. Simian looked and sees Jamie standing with the Watterson's. "Jamie, so decided to betray me too, how unfortunate."
"That's right you ape! I will no longer be insulted by you and my team. "
*hmph* so you turn against me because you complain about your looks. How pathetic but I'll have to give you point for standing up for yourself. However…
"Shut it Simian, nobody wants to hear your evil speech. Now surrender or else." Mega Cat said threating her.
"Or else what?"
"We'll force you guys to surrender." Mega Cat said aiming his buster on them.
"Oh my Lucy this boy got some mouth in him." Dr. Brown said to Dr. Simian
"Yes my sweets, I thinks it's time to teach him some manners. Both scientists hop inside the figure. Okay Gumball come after us now, this new project that we've been working on will be your ultimate opponent." The figure steps out of the shadow revealing a robot that looks like Mega-Cat but in adult form, it's 50 ft tall, it's 2 tails were covered in metal spikes, it has 6 arms, and it has some of the powers that are based off one of each of the robot masters they fought from previous times, the top left arm has Gumball's Buster, the top right arm has Bobert's Robot-Laser, the center left arm has Jamie's Rocket-Fist, the center right arm has Carmen's Needle-Launcher, the bottom left arm has Rachel's Rainbow-Flash, the bottom right arm has Flames Inferno-Thrower, it's legs have Johnny's Wild-Sprint, it's 2 tails has Dante's Two-Tail-Blades, it has Ora's Ninja Stars, and has Lancer's Slash-Sword.
"What the…
"Yes Mega Cat your opponent is yourself."
"Now! Come at us if you dare!" The top left arm turn into a buster, the bottom right arm turned to flames and the center left arm clutching his fist making him roar.
*Roar!* As the machine roar lighting struck multiply times.
"I-it looks exactly like me." Mega Cat said surprisingly
"Accept that it's ugly." Jamie smirked making Mega Cat mad.
"Careful guys this thing has all the 10 Robot Masters powers including yours?" Proto Cat said warning them.
*pssh* big deal, so what they built there ultimate robot. It's still going to be scrap by my fists." Jamie charge right at that machine. "Jamie wait." Mega-Dan tries to stop her but she's already ahead.
Jamie launch her fists at the head, but he used Johnny's Wild sprint to dodge it and fired his own Rocket-Fist. The Rocket-Fist crush Jamie on the ground
"Jamie! Let go of her!" Mega-Dan throws his Two-Tail-Blades at the machine's arm. When the arm got damage it let go of her and return back to his body. Mega-Dan grabbed Jamie and take her far away from him.
"Are you okay?" Mega-Dan asked easily lying on her on the floor with his siblings that are standing next to him. "Heh, don't worry about me I can take punch."
"Darwin keep an eye on her will you."
"You got it bro."
"Okay everyone let's take this thing down." Everybody charged right at him and fired him but his speed has dodge their attack. He used the Rainbow Flash on them except for Proto Cat because she's wearing her shades, He fired his Needle-Launcher on Proto Cat but she blocked it with her shield and continues running toward him. Mega Cat and Mega-Dan had regain their sights and catches up with Proto Cat.
"Grrrr! Annoying little pests! Take this!" The Robot fired his buster on them. The shot had knocked them back making Dr. Simian and Dr. Brown laugh.
"Fools! Do you guys think you stop us with your pathetic weapons?!" Dr. Simian laughed
They all got back up but suddenly they got hit by the robot's Inferno-Thrower. Next, the robot throws his Two-Tail-Blades and his Ninja-Stars at them but luckily they dodge it only leaving them scratched and marks on them.
"It's no used this thing is to powerful." Mega-Dan said in defeat
"No were not giving up, we've been through worse before and were are not going to lose by a bunch of senile couple. Now let's go!" They got back up again charged right at him again.
The Robot fired his Robot-Laser but Mega Cat quickly equipped his Plasma Shot and destroy one of his arm.
"Hey! Don't do that!" Dr. Brown yelled. The Robot fired both is Rocket-Fist and Needle-Launcher on Mega Cat but he was by Proto Cat when she blocked it with her shield and fired her buster on one of his arm leaving with some damage on it.
The Robot tries to use his super speed on them but Mega Cat quickly switch to Plasma Shot to Rainbow Flash to blind him.
"AHHHH! Copy Cat that's our stick!" With the robot and the scientist's tries to regain their sight, Mega-Dan sneaks behind him and sliced his tails. They gain there eyesight back and to sees that the robot's tail has been cut he turn around and see that it was Mega-Dan who did it. Mega-Dan was about fire his buster but he was grabbed by him.
"Well done Mega-Dan well done indeed. But even his tail got sliced he got more power to destroy you and your siblings. They turned to see Mega Cat and Proto Cat but they were gone.
"What the…where did they go?!" Dr. Brown asked.
"Okay Dante where are they and don't lie to us." Dr. Simian said threating him
"I don't know what you're talking Simian they were when I sliced your tail." Mega-Dan smiled.
What they didn't know that Mega Cat and Proto Cat are standing on top of the robot's head. Mega Cat blasted the hatch and enter inside giving Simian and Brown a spook.
"Mega Cat!"
"This is for Jamie, Danny and the others you dirty ape." Said Mega Cat fired at the control
"No! He destroy the controls!" When the controls explode the robot let go of Mega-Dan and lands on his feet. Mega Cat and Proto Cat grabbed Brown and Simian and took them outside of the robot. As they got out, the robot began to fall and crashes on the ground.
Mega Cat and Proto Cat drop both of the scientists to the ground and aiming their buster at their faces.
"Looks like you lose again Simian." Mega Cat said
"Don't get to excited Mega Cat I still got ace up my sleeves." Dr. Simian quickly took out a flash grenade a throws it at them causing to go blind. Proto Cat sees Simian making ran for it. Proto Cat was about chase after her but was tackled by Brown giving Simian a clean getaway into her saucer.
"No!"
"Hehehe looks like we won." Dr. Brown laughed. Proto Cat punch Brown in the face knocking him out. When the flash got clear, they regain their sights and sees Simian had vanish.
"Darn it! She got away again!" Mega Cat yelled slamming his fist on the ground. Mega-Dan walked up to his brother and pat him on his shoulder.
"Don't worry bro, will get her next time."
"I know, but we were so close, we could have end this war once and for all. But now we got to fight her again."
"And we'll keep on fighting her until she's defeated."
"That's right Gumball and were here to help you to the end because me and Jamie are on your side." Proto Cat said
"Yeah, your right." Said Mega Cat getting up.
"As long you guys with me, we will win this war." Mega Cat said
Suddenly Mega Cat got a message from his mom and she said she call the cops and they are headed to your coordinate. "I got a message from mom and she said the cops are on their way." Mega Cat announced them.
"Well let's go." Darwin said
"Come on Jamie." Mega-Dan said.
"Just…a…few…more…minutes." Jamie said punching the head of the fallen robot.
"What are you doing? " Mega Cat asked
"Punching your face that's why." Jamie continue punching the robot's head. "Eat this you lard crud." Jamie continue punching.
