A spoiler to this story.

To anyone who doesn't want to see it, please skip it.

I will be making the 2003 Hulk movie canon and the 2008 movie non-canon in this story.

The reason why is because Hulk 2003, to me, is an underrated gem & a thing of beauty in my opinion which is fascinating with how its symbolism & Hulk's origin feels natural to me.

XXXXX

(And now, back to our original programming.)

XXXXX

(Dark Bat's POV.)

As we arrived at the cloning warehouse and as we all got out of the Bat truck, a loud screech was heard.

The sound so glass was heard as a bat-like creature smashes through the skylight window.

Red Hood: "What the hell?"

Batman looks at the creature starts to screech louder and as it does, bats start to attack the group.

Louie: "What's going on?"

Huey: "It's the creature!"

Dewey: "What?!"

Me: "The creature and its screeches can control bats into being its attack force."

I look and saw a blue gem around its collar.

Dr Banner: "And I think I know how it's doing that, look around its neck."

The others look to see what I was looking at the creature and notice the second dance gem attached to the collar around its neck.

Robin: "How are we suppose to get the gem?!"

Louie looks around to see every angle & sees another warehouse and looks back at the Manbat, giving him an idea to stop it.

He turns to Phineas, Ferb and Milo.

Louie: "Can you three buy us a little more time to come up with a plan?"

Phineas: "On it."

Phineas presses a button on the top of the back of the giant mech suit known as The Murphy's law mark II suit transforms and gets to its original height.

As it finishes transforming, Ferb put the radioactive watermelon in the back to power up the suit and the three got in the suit.

With Phineas, Ferb and Milo fighting Manbat, Louie tells his plan to the group.

Louie: "I think I have a plan to get the gem, you said that the warehouses the Joker use to have as a hideout had been made into laboratories. Including one with sound weapons, right?"

Me: "Correct, why do you ask?"

Louie: "If we can find a lab with sound weapons, we can distract it enough for someone to grab the second Dance gem."

Dark Bat: "That might work. Mrs Beakley, there's a weapons warehouse nearby the clone warehouse with sound weapons that scare off non-anthropomorphic animals with a bat setting in the second cupboard near the entrance, do you think you can handle them?"

Mrs Beakley nods her head and runs to the weapons warehouse as Batman looks at Dark bat, confused about how he knows all of the layouts of the warehouses and which one is the exact warehouse he's talking about.

Red Hood: "It's a good plan but one problem. Who's gonna grab the gem?"

Louie then looks at Dr Banner as he looks back.

Dr Banner: "What?"

Louie: "As the Hulk, you can leap to Manbat and grab the second dance gem on its collar."

Dewey started laughing at the name Manbat as Dr Banner shakes his head.

Dr Banner: "No way! Once I get too angry, the formula wears off and I don't want the Hulk harming anyone!"

Louie: "How do you know that the Hulk will harm anyone?"

????: "Good question, Louie."

XXXXX

(Your POV)

Everyone looks to see me as I pause time and put the group along with Dark bat, Batman, Robin and Red Hood in Bruce's mind as mental projections.

As I did, everyone was confused about what's going on and how Dr Banner was in his human form which is more than understandable since I came unannounced.

I look to see Batman, who is looking at me with a grim look on his face.

Batman: "Who are you? And what did you do?"

Me: "My name is (Y/N) and I paused time in this universe & put us all except for Milo, Phineas & Ferb along with Manbat & Mrs Beakley into Dr Banner's mind-scape to help him with his insecurity of the Hulk."

Dewey looks around to see a gigantic, dark green door reveals itself with a label on the front of it with a dark green lock around it.

Dewey: "The other guy?"

Dewey gets closer to the door and pokes the lock as Bruce Banner sees the blue-shirted duckling doing it and knew what it is.

Bruce Banner: "Wait!"

The lock disappears after the fifth poke, letting the door slowly open and reveal a shadowy figure of the Hulk.

The eye of anger notices Bruce Banner and roars at him in rage.

Hulk: "HULK SMASH PUNY BANNER!!!"

The Hulk goes over to his other half to punch him but I teleport Bruce to the door, making the Goliath miss.

Batman reaches for some Batarangs & throws them at the Hulk, hitting him.

Red hood puts the safety on his guns and tasers the Hulk.

Damian gets his staff using it to get the Goliath to his knees.

Kirk gets a handful of tear gas pellets and throws them at his eyes, temporarily blinding the Hulk.

The Bat-Family thought they were slowing the Hulk down but that only angered him.

Me: "Don't use your gadgets to slow the Hulk down."

Dewey: "Why not?"

Me: "That will only make the Hulk angrier and he gets more stronger that way."

The Hulk turns to face the Bat-family and roars in rage.

Hulk: "Gadget men hurt Hulk, Hulk rip off gadget men's heads!"

Damian: "Our heads?

Jason: "Oh crap."

Bruce Banner gets an idea to trap the Hulk and yells at the giant.

Bruce Banner: "OVER HERE, YOU BIG GREEN ASSHOLE!!!"

The Hulk looks to Bruce, angered by the insult.

Hulk charges at Bruce but missed him as the professor dodged and charges inside the door.

Bruce then closes the door, so the Hulk doesn't come out.

Bruce Banner: "And stay in there!"

Dr Banner turns to all of us worried about what we would think.

Dark Bat: "That's the hulk?"

Bruce Banner: "Yes... and it's back where it belongs. The Hulk is a monster that I've been unable to control and even though I've merged with it, he has been giving me nightmares ever since Sigma went down."

I notice Huey go up to Dr Banner with a small smile on his face like he's been through what Bruce is going through right now.

Huey: "Take it from someone who use to have a struggle with emotions. You can't ignore the parts of yourself that you don't like, even the parts you are afraid of. You need to own them."

Bruce Banner: "But he is pure chaotic rage!"

Huey: "And you are pure frustrating order! If anyone can handle the Hulk, it's you."

Bruce looks at Huey, then back at the door and takes a deep breath.

The strongest avenger then opens the door, goes inside and closes it.

I smile and snap my fingers, letting all of us exit Bruce's mindscape.

XXXXX

(No one's POV, outside of Bruce's mind.)

You resume time as everyone gets out of Bruce's mind & Mrs Beakley gets the sound weapons.

She gives everyone except you, Batman, Bruce Banner, Milo, Phineas and Ferb a sound weapon.

You: "Agent 22, I have a lot of explaining to do but right now actions speak louder than words and I've only got three of them for everyone. Aim and fire."

Mrs Beakley nods her head as everyone fires the sound weapons.

You then notice Bruce slowly gets bigger and turns a brighter shade of green.

One by one, everyone stops firing and looks to see Bruce has fully transformed into the angry being known as the Hulk.

The Hulk screams in rage as he jumps at Manbat, smashing a warehouse as Manbat bites into the green Goliath, drinking his blood with the creature's skin slowly turning a pale green.

As the bat-like creature gets off, it slowly reads the mind of the Hulk thanks to the brain the Joker made combined with the Gamma radiation in his blood.

Manbat starts screeching very loudly until it said one simple word.

"More."

XXXXX

(No one's POV.)

Manbat charges at Hulk but gets punched so hard it got knocked down.

Hulk turns around and sees the Bat-family, thinking that they were trying to kill him.

He goes over to attack, screaming in rage.

Fortunately, with the space & reality stones, you moved the Murphy's Law MRK 2 suit away and created an invisible & indestructible bubble-like barrier to hold only the Hulk, ManBat and something else in until the situation is sorted.

Unfortunately, Hulk starts to slowly turn back into Bruce Banner because of his fear of hurting people as Manbat gets back up and bites on his back, sucking up more & more gamma radiation and blood, heavily losing his consciousness by the passing second.

Huey realises that Bruce is still worried about the Hulk but also see how to stop ManBat.

Huey: "Bruce!"

Bruce looks at Huey as everything becomes darker and darker.

Huey: "The Hulk is you, channel your inner strength!"

XXXXX

(Bruce's POV, inside his mind.)

I look around the dark part of my mind, seeing a giant thunderstorm with green lightning lines connected to me and shows my memories.

Memories of my father.

I look at the Hulk who has was throwing boulders and roaring at the storm, which was slowly taking the shape of the Manbat.

"That's right, keep fighting. The more you fight, the more of you I take."

As the Hulk roars at the storm, I start to see an emotion I never thought I would ever see on the Hulk.

Fear.

XXXXX

(Outside of Bruce's Mind, your POV.)

Red hood grabs me by my shirt as the others start to worry about Dr Banner and Hulk being drained of blood & some of the gamma radiation from his body.

Red hood: "What are you doing?! Take the shield down!"

Me: "I can't."

Batman: "Can't or won't?"

Me: "Thank you for correcting me since won't is more appropriate than can't but I still choose not to take the barrier down just yet."

I straighten my shirt before Jason lets me go.

Dark Bat: "Why not?"

Me: "Because of the power deep inside Bruce Banner and the Hulk."

Everyone looks at the inside of the barrier as it starts to frost up.

Me: "The frost is Manbat's doing thanks to the gamma radiation in its system, which is now absorbing heat from inside the barrier."

Dark Bat: "If that isn't the kind of power Bruce has, then what does he have?"

XXXXX

(Bruce's POV, inside of his mind.)

As I stared at the Hulk more and more, he notices me, turns in my direction and his hands formed fists.

I felt nervous and wanted to run but I didn't.

I took a deep breath from my nose and exhaled through my mouth as I looked at the Hulk.

We steadily go over to each other.

We both stop as we both face each other as we start to calm down bit by bit.

I then start to look at the Hulk, seeing him not as a monster that needs to be ridden of but as something I never considered him as.

Family.

I smiled at him as he looks at me.

We both turn to see the storm grow in size more rapidly.

Manbat: "Sleep little Bruce and forget forever, struggle no more and give me your power!"

The Hulk looks back to me, winking with a smirk on his face as I realise he has an idea and I nod to him.

Me: "You think you can live with it?"

My smile turns into a small smirk as I turn back to the Manbat storm.

Me: "Take it!"

XXXXX

(Outside of Bruce's mind, no one's POV.)

Bruce instantly turns into the Hulk as Manbat takes its fangs out of his body.

Hulk looks at the creature and yells one sentence.

"TAKE IT ALL!"

The Hulk radiates massive amounts of gamma energy inside the barrier, allowing Manbat to absorb more of it.

Manbat: 'Yes! Yes!'

The hulk roars in rage as more gamma radiation flows violently inside the barrier.

After a while Hulk loses consciousness and turns back into Bruce Banner as Manbat starts screeching in agony, not being able to absorb any more of the gamma radiation and causing Manbat severe pain to its body.

Manbat's brain starts to fry up and the heart starts to pump so fast, some screws start to come loose.

You go over to the barrier, moving it up in the sky while removing the gamma radiation from both the field that was inside the barrier and Manbat's body.

You slowly remove Manbat & Bruce's unconscious bodies from the barrier and slowly putting them down, without harming them.

You also changed Manbat's body, the organs including the brain and heart to human.

Also giving 'Manbat' knowledge and his body a regenerative healing factor type VIII along with blood generation & some special immunities to radiation, all meta powers, contamination and pain that is compatible with any blood type and anyone who is injected will gain his abilities.

Using the reality stone, you swiftly changed the gamma radiation into oxygen and the barrier vanishes as a giant wave of fresh air fills the atmosphere.

You look at Dark Bat, who was quite surprised about the Hulk defeating the now meta-human 'Manbat' with some of the gamma radiation he had released.

Dark Bat: "That was the power inside him?"

You: "That was the power inside them."

Batman: "What happened to the gamma radiation the Hulk released?"

I showed Batman my arm and pointed to the reality stone.

You: "I used the reality stone to turn it into oxygen."

Batman slightly smiles until he turns to Bruce Banner and 'Manbat's' unconscious bodies.

Dewey: "So... now what?"

You look at both bodies and decide to wait for them to wake up.

XXXXX

(Your POV, 5 minutes later.)

The group and I look at Bruce Banner and our friend, waiting for them to wake up.

As they do wake, instead of Bruce being worrisome, he was more calm, collective and confident as Cyrus is a bit nervous.

Bruce: "What happened?"

Me: "Cyrus, who was once the being called 'Manbat', was drinking some of the Hulk's blood contained with Gamma radiation, which also enhanced its heat absorption which caused the barrier to get colder and is quite astonishing since bats take up heat from their environment, which can be like how humans & Faunus absorb heat except we don't have 15 times the metabolic rate since we can't fly..."

Bruce: "(Y/N). We apologise for interrupting your talk about temperatures, bats & heat but is it ok for you to cut to the chase, please?"

I then look at Bruce and the others, realising that I need to get on with what has happened around the Hulk and Cyrus.

Me: "Oh, thank you for telling me. Anyway, your friend started screaming in rage as Gamma radiation exploded out of your body which overloaded Cyrus."

Cyrus: "Cyrus?"

Me: "I named you Cyrus because the name suits you."

I then walk over to Cyrus, took off his collar, took the gem out of the device and looked at Batman.

XXXXX

(Batman's POV.)

My cowls communicator starts to ring as (Y/N) looks at me.

(Y/N): "You might want to answer swamp thing's call with the communicator in your cowl, mr Wayne."

I was surprised he knew who I was but I kept my composure and pressed the answer button.

Me: "This is Batman."

???: "Batman."

Me: "Swamp Thing."

Swamp Thing: "You would not believe what the Joker and Trickster were doing."

Me: "What were they doing?"

Swamp Thing: "They tried to kidnap Mark Hamill, unfortunately for them, they didn't know that Mark is also a talented voice actor and he used his talents to drive them onto the grass where I would take care of things."

I blinked in surprise, now knowing why he made the clone.

(Y/N): "You're correct. They did want you out the picture to kidnap Mark Hamill but when the group came to your universe, Joker had to speed up his plan."

Me: "Thank you, Swamp Thing. Batman out."

I turn off my com and looked at the group.

XXXXX

(Your POV.)

Batman: "You know, (Y/N). When you & your team came to our universe, I thought you were arrogant and self-centered..."

Me: "But..."

Batman: "But you & your allies proved me wrong and have showed me that you can be trusted."

Just after Batman finished saying what he wanted to say, Jason chuckles in surprise hearing Batman admitting his faults and a certain someone grabs me.

While most of the others were a bit nervous thinking it was an attack, I was calm because I knew what it was.

Hulk: "NOOGIE NOOGIE NOOGIE!"

I started laughing due to being ticklish when the Hulk noogies me.

Me: "Ok, ok! It's good to see you too, big guy."

The Hulk lets go as I catch my breath from laughing and hold out my hand as a sign of friendship to Batman.

Me: "May our paths cross again."

Batman shakes my hand in response as I open a portal to our world in the avengers facility.

The group I assigned go through the portal but before I went back home, I look to see something fascinating at a distance.

I smiled slightly, nodded my head, knowing who the being is and turned back, walking through the portal before it closes.

XXXXX

(????'s POV.)

As the Bat family go back to their home, I go back to Remnant-Earth 6721.

I know who the bigger threat really is.

I could warn them about the being but I cannot, must not intervene.

XXXXX

(Dark Bat's POV, two days after getting the Joker to Arkham and Trickster to Iron heights.)

I finished working on some of the Automatic target Batarangs upgrades.

I was about to work on some of the ice Shurikens for Damian, I sensed that a certain something or to be accurate, a certain someone is in the room with me and I looked to see his reflection.

Me: "Hi Bruce."

I turned around and saw his confusion on his face like something was bothering him.

Me: "I'm guessing Cyrus is doing well."

Bruce: "How do you know so much about all of the warehouses?"

I look at the Batcomputer and than back at Bruce, knowing it's no point in not telling him.

Me: "My father was the one who designed them for Wayne enterprises. Around the same time, I cured my Lymphoma and accidentally splicing my DNA with the nano-bots and bat saliva."

Bruce: "Your last day of college."

I nod my head.

Me: "A few months ago before I ran into you, Alfred & Damian, a few people who lived there said that he was killed by a robber at the wrong place at the wrong time."

Just as I said 'wrong place at the wrong time.', I can see Bruces realisation on his face, despite how calm he is.

Bruce: "You're Abraham Langstrom's son."

I nod my head, deciding to get back to work but as I did, Batman went over the working table with me and what he said caught me off guard.

Bruce: "Do you want some help?"

I looked at Batman and back at the table, smiling.

Me: "I would like that."
