In this chapter, our heroes will fight the Doctor. Hence the chapter title. I figured I would look up a doctor idiom for this chapter title. And this is the one that I chose.

What do you think?

It looks like this is the final battle.

Or is it?

Who knows? We'll just have to wait and see.

It makes me feel happy that this fanfic has gotten over 100 reviews.

And yes, they've been positive reviews.

A lot of them are from the same guy, but I digress.

Chapter 73: Go for the Doctor

"I wonder if the Doctor is allergic to wild parsnips and dairy like I am..." questioned Candace to herself. After all, she was her dark reflection. One could say the same for Shego regarding Kim as well.

The Doctor fired lasers from her throne.

Our heroes were forced to take cover.

Luckily, this wasn't the first time that Kim had to dodge lasers. She had once gone through a laser grid to rescue two people, after all.

In fact, she was kind of used to that sort of thing by now. Like the time that she had gone up against the Senors' animatronics. Ron never thought that JP Bearymore would try to destroy him. He always happened to like eating pizza at his restaurant.

Perry the Platypus had experience dealing with that sort of thing as well.

Ron was still frightened, however. He scared a lot easier than Kim did. Though one couldn't really blame him for getting scared. He had encountered the likes of Dr. Drakken, Duff Killigan, and Monkey Fist.

In addition, something embarrassed happened to the wielder of the Mystical Monkey Power.

"My pants fell down again!" exclaimed the young man who had recently graduated from high school.

Quickly, he pulled them up.

Unfortunately, he had forgotten to wear his belt today.

"I should consider myself lucky I wear a catsuit." noted Atrosis, who had witnessed the event.

"Just relax and accept me as your royal highness!" exclaimed the Doctor.

That's what the Cowards had done, more or less. Though some of them had decided to rebel recently. Mama hadn't taken control of everyone. Though now that she had access to more oxygen, things would change.

"How about no." answered Shego.

She had already experienced mind control before. And she didn't want it to happen again. Why did Dr. Cyrus Bortel invent the mind control chip, anyway? To her knowledge, he was not a mad scientist.

Incidentally, Professor Dementor had also experienced what it was like to be mind controlled. Luckily, his assistant decided not to take advantage of him...mostly. She was very loyal to him.

Atrosis rolled into a ball, then crashed into the force field.

This succeeded in doing some damage.

However, the force field was still intact.

If they wanted to take out the force field, they were going to need more...force.

The Doctor proceeded to launch missiles at the heroes.

Ron screamed.

As before, our heroes were forced to take cover.

The missiles made scorch marks wherever they landed.

Shego launched a plasma beam at the force field.

This did some damage.

In retaliation, the Doctor pressed a button and a giant hammer appeared.

It attempted to strike everyone near it.

To make matters worse, the hammer happened to have spikes on it.

"How many weapons does that throne have?" asked Ron.

Rufus shrugged as he tried to avoid ending up like a mole at the arcades. The hammer was especially dangerous to him given his small size. Though his small size also made it harder for the hammer to hit him to begin with.

It certainly was a powerful device, that was for sure.

One could only hope that they could destroy it.

Though Rufus did note that this wasn't the first time that he had gone up against a machine.

The Doctor pressed a button and out came a freeze ray.

"Uh-oh." remarked Atrosis.

If she got hit by that, she would be in trouble.

Granted, she had the professor for protection.

But even so, she didn't want to become a popsicle.

Gill and Camille noted it would be best if they avoided that freeze ray as well.

That was how Dr. Doofenshmirtz had managed to get the better of them.

Speaking of him, he zapped the force field with his ray gun.

The force field shattered.

The Doctor gasped in alarm.

It looked like she was vulnerable.

"Booyah!" cheered Ron. It looked like they were winning.

"Uh-huh!" nodded Rufus.

Afterwards, the Doctor's chair deactivated.

It looked as if it was in need of repairs.

Tim and Jim were watching the battle on TV.

They were of course rooting for their sister. It was a bit ironic that thy were the ones cheering her on given that she was a cheerleader. But she would most likely appreciate the support, nevertheless.

"Yeah! Wipe the floor with her, Kim!" exclaimed Tim, raising his right fist in the air.

"This alien invasion stuff is really cool..." noted Jim. Of course, there had been another alien invasion not too long ago. However, the power hadn't gone out this time.

"I just hope that the aliens don't mind-control us..." hoped the boy in the red shirt.

Otherwise, they likely wouldn't be able to play video games. They would be too busy bowing down to the Super Super Big Doctor for that sort of thing.

And yes, those video games were sci-fi related.

Hopefully Kim could get things straightened out once and for all.

"I have to admit, no matter how many times that Kim saves the world, it always seems to end up in jeopardy again." noted Tim.

Of course, Kim wouldn't be so famous if the world didn't end up in jeopardy to begin with.

Jim shrugged. He wasn't sure why the world kept ending up in jeopardy.

He just hoped that Kim could save it once more.

Meanwhile, the Super Super Big Doctor's hands began to glow.

"It looks like I'm going to have to dirty my hands a bit with this one." noted the evil dictator.

Considering they had defeated the two Lorwardians, it wasn't such a big surprise.

No matter. She had consumed the power juice that they had given her.

She was still in the fight.

Which was good, since her troops wouldn't do well against the enemy without their leader.

Though she had to admit, conquering Earth was proving to be a challenge. Conquering Feebla-oot had been a breeze, but this planet was a whole different story.

Would other planets put up this much of a fight? She heard that Mars was named after the god of war.

Things certainly were interesting, she could say that much.

She launched several energy balls at her enemies.

Kim backflipped to dodge the deadly energy.

Phineas decided to take advantage of the situation now that the force field was out of the way.

"The force field is down! Ready the T-Shirt cannons!" ordered Phineas.

"Way ahead of you, Phineas!" exclaimed Isabella. Unsurprisingly, she was following Phineas's commands to the letter.

"Can I have one?" asked Atrosis curiously. It seemed like they had quite a few.

Having a T-Shirt would be awesome.

Though they weren't in her color.

"We need them to defend ourselves from the aliens." explained Isabella. The more ammo that they had, the better. They didn't know how many soldiers the Doctor had, after all.

"All the more reason to end this invasion, I suppose." noted the sidekick of Professor Dementor.

The sooner the invasion ended, the sooner she got a T-Shirt.

Unfortunately, the fact she frequently teleported made the Doctor hard to hit.

And to make matters worse, reinforcements showed up to defend their master.

She wasn't losing to the heroes on their watch.

"You'll never defeat the Super Super Big Doctor!" exclaimed one of her minions, brandishing a spear. He was decidedly loyal to his mistress.

"Don't you think that name is kind of long?" questioned another minion, who was wielding a hammer, similar to what the Super Super Big Doctor had attacked the heroes with earlier.

It was a lot simpler to simply call her the Doctor. Just as Ohfortheloveofpete did at times.

But of course, the Super Super Big Doctor had an ego to her. Hence the giant statue she had built on Feebla-oot.

Kind of like Dr. Drakken himself.

"Huh. That makes me wonder if I should shorten the name of Doofenshmirtz Evil Incorporated." noted Doofenshmirtz. Though he did prefer to be called Doofenshmirtz rather than simply Doof.

Maybe he should just call his villain lair Doofenshmirtz Evil Inc.

Irving blasted some of the minions with T-Shirts.

"i wonder why they get so excited over T-Shirts." questioned the bespectacled boy.

Whatever worked against them, he supposed.

Meanwhile...

As it turned out, the Senors were watching the show as well.

"I hope Shego can defeat the aliens." remarked Junior. If they fell under mind control, the aliens could force them to give away all their money. Though he knew that Bonnie wasn't dating him simply for the money. Though she had acted like a gold digger when she was around Ron once.

"I'm rooting for Atrosis personally." noted Senior.

"Hasn't she gone off the deep end?" asked the young man in a yellow shirt. She had been sent to an asylum a few times.

"It's always nice to meet a villain who's interested in being evil. Though I suppose she is a lot more energetic than I am." admitted the elderly villain. It helped that she was a lot younger than she was.

Perhaps he should consider investing in technology that could replicate her elastic powers. Of course, he could also hire her in the event that her employer was taking a day off.

"I have to admit, I find it odd that she and Shego are working together." noted Junior.

"How so?" asked Senior. He was willing to work with Atrosis. After all, she was rather friendly towards him.

"Atrosis and Shego have totally different personalities. That's why they're feuding." explained the young man who was filthy rich.

Now that Senior thought of it, Atrosis was a lot more energetic than Shego was.

Of course, he knew from experience that there was a lot of variety when he came to villains.

"I suppose we should be rooting for both of them." noted Senior.

Junior nodded. They were trying to save the planet, after all.

Back at the arena...

Since the Doctor was proving difficult to hit, the heroes decided to use the T-Shirt Cannons on the minions instead.

This caused them to explode.

"Awesome! A free T-Shirt!" exclaimed one of the minions, right before exploding.

"Phew!" exclaimed Phineas, wiping sweat off his forehead.

It was a good thing they were good shots with those cannons.

Candace found it ironic that she heard her name whenever they exploded.

Namely because she was one of the people shooting them.

Likewise, the Cowards helped by fighting the minions.

They certainly were feeling a lot more confident.

The Doctor shook her fist in anger.

She fired a beam at our heroes, which hit Kim.

"Ow!" exclaimed Kim.

It was a good thing her suit was capable of repairing itself. She would thank Wade for that feature later if she managed to win against the aliens.

However, Shego retaliated with a beam of her own.

'Ouch!" exclaimed the Doctor.

Phineas then followed by hitting her with a T-Shirt cannon.

This was a direct hit.

"Yes! We hit her!" cheered Phineas.

However, it seemed that she was made of tougher stuff than her soldiers. A single T-Shirt wasn't going to do it.

In retaliation, she retaliated by launching a pink tornado at Shego.

It was a direct hit.

"Ow!" exclaimed Shego. It was a good thing she was super resilient.

"Whatever happened to the Hippocratic oath?" questioned the brunette.

Dr. Doofenshmirtz shrugged. He had broken that oath a long time ago when he fought against Perry the Platypus. Though in his defense, he was a friendly sort of enemy.

Kim Possible punched the Super Super Big Doctor in the face.

She was sent flying several feet.

"Aarghhh!" exclaimed the Super Super Big alien. She had really felt that one, that was for sure.

Kim noted that having super strength sure was useful...especially when you were wearing a super suit. Hego would attest to that, though he would likely lose to his sister in a fight.

However, the Super Super Big Doctor wasn't out of the battle just yet.

In fact, she was just getting started.

She began to glow pink.

"That isn't a good sign." noted Ron.

Rufus gulped.

It looked as if the Doctor was about to go berserk.

She began to attack much faster than before.

In addition, her energy balls were much bigger.

She also teleported greater distances.

Ron used his Mystical Monkey Power to attack the Doctor.

However, she blasted Ron with a laser beam.

"Ow!" exclaimed Ron.

"You OK, Ron?" asked Kim.

The blonde nodded.

The Doctor used her telekinetic powers to lift a car and toss it at Kim.

But she tossed it right back at her.

She was left stunned.

"Ow! My head!" exclaimed the Doctor, who pressed her hand against her forehead.

Candace hit the Super Super Big Doctor with a T-Shirt Cannon.

The Super Super Big Doctor fell to her knees. The T-Shirt had caused her legs to become wobbly.

"Yes!" exclaimed Candace. She was glad that she had managed to secure victory for her team.

The Cowards clapped and cheered.

It looked like their planet was finally free.

They would make a thank-you card for the heroes later. Not least for helping them find their courage.

"Are you ready to surrender?" asked Shego, waiting for her opponent to pull out a white flag.

Personally, she wanted to get a nice suntan after this.

"No! I had the entire solar system in the palm of my hand!" bellowed the Doctor.

It looked like her evil plans weren't going to succeed. The heroes had simply proved themselves to be too much for her. Just as they had proven too much for the two warriors that had assisted her with her plans.

Which was a shame for the Lorwardians and herself, since they had worked hard on them.

"I guess the Doctor should have quit while she was ahead..." noted Kim.

"Why did you decide to enslave a planet, anyway?" asked Candace.

Surely there had to be a reason. She knew Dr. Drakken had decided to conquer the world because he felt disrespected by his peers. Kim Possible had told her about that.

Likewise, Professor Dementor was bullied because of his short size. Luckily, Atrosis treated him well despite clearly being the taller of the two.

"To be honest, I always felt overshadowed by my brothers..." remarked the Doctor.

It was surprised what they were capable of.

Not only that, but they had made more than a few friends. People always invited them to their parties...not least because they had set up an awesome party for their mother.

They were very charismatic.

After taking over Feebla-oot, she no longer felt that way.

"Everyone's special in their own way." pointed out the redhead. Though she would rather be normal than be an evil dictator.

She knew that people were impressed with how fast she was. It made her question whether she needed a bicycle or not. Though she did admit she happened to like her bicycle.

"Huh. Maybe I don't need to conquer planets after all." answered the alien.

Ron sighed in relief.

It looked like the invasion was finally over.

Perhaps it was time for the Super Super Big Doctor to stop using a mind control plant to get what she wanted.

And maybe she should stop treating her own brothers like prisoners.

However, speaking of that mind control plant...

...suddenly, a vine grabbed onto the Doctor by the ankle.

"Aah!" exclaimed the Doctor.

Mama then swallowed her whole.

Afterwards, she let out a burp.

"Whoa!" shouted Phineas. He hadn't been expecting that.

Candace's eyes widened with shock.

Though their sister had decided to lock them away, the Super Super Big Doctor's brothers couldn't help but feel frightened by the turn of events.

"Zis reminds me of when I used plants to try to take over ze world..." noted Dementor. Who would have thought that herbology would be so useful for world domination?

However, this plant seemed even more aggressive than the ones that he had created.

"Really?" asked Atrosis.

Perhaps he shouldn't try that evil plan again. Not until he was sure he could control those evil plants.

Ironically enough, he knew that Dr. Drakken had acquired plant powers recently.

"Oh no! Not our evil overlord!" screamed one of the evil minions.

Shortly afterwards, they heard a roar.

It looked like Mama was out of control. It seemed that the Lorwardian's machine had worked a little too well. Maybe the Doctor should have set it to a lower setting. Though to be fair, she wasn't experienced with Lorwardian technology.

Not even the Doctor could control Mama now. That had been made all too clear.

They immediately began to panic.

Perhaps it would be best if they retreated. Though it was doubtful they could go back to Feebla-oot seeing as Mama wasn't producing her mind control spores there anymore. They would most likely be thrown in the dungeons by the Cowards...once they came back to their home planet.

Unfortunately, the plant monster decided that it would eat the minions as well. It seemed that she was still hungry. And apparently, aliens happened to taste good.

As she ate, she grew bigger.

It seemed that the more she ate, the stronger she became. Which made her all the more dangerous.

Mama let out another roar.

Miraculously, she was still hungry. Her appetite was insatiable, it seemed.

"I want my mama!" exclaimed Baljeet, who was now sweating nervously. Was he going to be plant food?

"The plant's name is Mama. How ironic." remarked Buford.

For once, Irving wondered if he should have accompanied Phineas and Ferb on one of their journeys. He was in danger now.

But then again, they appreciated his help combating the aliens.

It looked like they had gone out from the frying pan and into the fire.

"We're not getting paid enough for this..." remarked Dash.

"I thought you guys stopped accepting money in exchange for heroic services." questioned Ron.

"Oh, right." answered the leader of Team Impossible.

Could they stop the plant before she consumed everyone in Danville?

The whole city was counting on them.

Heck, maybe even the entire world!

Uh-oh! It looks like Mama has grown out of control. Of course, I already said that as the narrator. And you likely saw this coming if you saw the movie.

Just as the Doctor was about to make peace with our heroes too. At least that's one less threat to deal with.

Perhaps she should have been more careful with that plant.

It looks like our heroes are going to have to take care of things.

Can they destroy it before it consumes everyone in Danville?

Perhaps Dr. Drakken can help. Herbology is kind of his speciality. Though I can't say the same for artificial intelligences. Heh heh.

See you next time.
