Author's Note: Here is another AU Songfic for the AU week! This one is a recommended one and it was a long time coming, this is was recommended by grimlock987.

This one will be set in the Gem Bros AU. In short another spin on Water Mom but if Lapis was apart of the Crystal Gems in the beginning and Dipper was raised along side Steven.

This takes place during Weirdmageddon. But this songfic will be portrayed as a music video if you will.

Brothers in Arms.

Standing in the middle of a field stands two boys who, since as babies saw each other as brothers.

Dipper and Steven Universe.

The boys saw all their friends and family running up to them with smiles on all their faces.

But then the ground started to shake, the sky turning red and a large pyramid rose up from the ground and a large gust of wind blew everyone away, except for the boys.

Steven and Dipper where pushed by the force of wind in different directions but they fought as they tried to reach for each other.

Their hands nearly touch, only till after a sinister laugh echoed across the winds that the two boys where pushed away from one another.

Then Darkness.

Dipper opened his eyes and stood up from the ground and saw many statues of people in terror, then he felt someone behind him. Dipper turned around and saw two of Bill's henchmaniacs, Teeth and 8 Ball glaring at him, ready to end him.

Dipper frowned at the two monsters and pulled from his back a sword and faced them.

He was not going to make it easy for them.

A normal kid would've given up, all out of luck their heart's struck.

While the devil plays his little game, such a tragedy!

Dipper charged forward but the two demons dodged the attack only for Dipper to make a fast turn and slash at 8 Ball's back and jump on top of Teeth's…head? Then Dipper slammed the hilt on him and jumped off.

And the world we know was painted black, now take it back, you attack, just prepare your boots for adventure, it's in the bag!

The demons growled and charged at the boy but Dipper managed to avoid every hit that they tried. Until an eye bat slammed behind Dipper and 8 Ball grabbed his leg and slammed him down as Teeth kicked him hard causing Dipper to be pushed back.

They'll faced the gravest of mistakes, doomed by the eyes of a snake, you must rejoice with your old chum as you run and gun.

Dipper felt pain but he was not out. Not yet, he was not about to let these freaks and they demonic master win.

Up in the clouds and on the ground, inward bound, so profound.

8 Ball and Teeth charged at the wounded boy but then a wall of water appeared and started to cover the two monsters.

Make 'em pay the price for taking over, with the luck of a four leaf clover through the hills of apocalypse, you saturate this whole place with your magic fingertips.

Dipper looked up and saw his adoptive mother Lapis as she glared with hatred over the things that dared to attack her boy. Then Dipper felt a hand on his shoulder and saw his teacher Pearl standing by him with her spear drawn.

Like an eternal eclipse you shine.

The creatures struggled from their predicament as Dipper picked up his blade and faced them.

So make it rain!

Dipper, Pearl, and Lapis charged at the two and attacked them one by one.

Brothers in arms, they will run, they color up the rainbow that bangs on the drums.

The fable will prevail as our heroes travel far.

In this altered universe you're a pest, now put me to the test!

Both 8 Ball and Teeth teleported away before they where finished off by their attackers, as they fled Lapis flew down and hugged her son, Dipper let go and looked to the dark pyramid and he, Lapis and Pearl all headed towards the evil lair.

Steven woke up as Connie and Mabel stood by him as Pyronica, Pacifire, and Keyhole stood around them.

Steven instantly summoned his shield as all three of the demons attacked.

Our paths foretell of many heights on the ground or take flight.

There's a problem dwelling over there for those who even dare.

Connie got out Rose's sword and Mabel pulled out her Grappling Hook as they tried to defend they friend.

For you see this cryptic renegade with your friends, there's no shade.

Pyronica jumped over the girls and was about to step on Steven.

Will they face the big battle royale?

Then a whip wrapped around Pyronica's leg and she was then swung away from Steven as the holder of the whip Amethyst landed near him and gave him a thumbs up.

Amethyst: You got it pal!

Then Garnet jumped out and fired her gauntlets at the other two demons, knocking them down.

With strength as strong like projectiles, make the boss infantile. These monsters hail from the dread they come to take your head.

Steven saw Pyronica rise up only to be knocked down but Lion with Wendy and Soos on his back.

May god enlighten your road, may your journey behold, try not to slip through the riverside.

All three demons stood up together as the rest stood in front of Steven protecting him from the monsters.

The weather brings hell to the tides as the devil would lick his lips, you overcome this homicide like the magic by your side.

Steven placed a hand over his gem and griped his shield tight.

Like an eternal eclipse you shine.

Steven jumped in front of his friends and stood facing his foes with a look of determination.

So make it rain!

Steven ran ahead with the rest following close behind to aid him as they fought the three demons.

Brothers in arms, they will run, they color up the rainbow that bangs on the drums.

The fable will prevail as our heroes travel far.

In this altered universe you're a pest, now put me to the test!

All three demons retreated from the fight while everyone else congratulated each other, but Steven kept his gaze on the flouting pyramid, he got up on lion and with his friends they charged towards it.

Dipper ran ahead of his group and Steven the same soon the boys noticed each other as they got close to the pyramid, Steven jumped off of lion and ran towards Dipper.

The two boys where about to hug but then they noticed their friends are not with them just them and lion.

As well as their real enemy sits above them on a throne made from the statued humans.

Bill Cipher: Ah, see the roulette spins you're seriously out of luck.

You stupid souls, you feel awful, cause this's my hell you shmucks!

Now the price you'll pay to end this day sets challenges far and wide.

For the time has come, your journey's done, cause both of you will die!

HAHAHAHA!

Bill vanished and in his place Xanthar stands tall and ready to kill.

What will we do?

Dipper looked at his brother.

Let's form our crew!

Steven looked at his brother.

Let's bring this back to life!

They grasped each other's hand as Steven's gem glowed and with a flash of pink stood not two boys but instead the combined form of two brothers.

It's Stepper's turn to fight.

Brothers in arms, they will run, they color up the rainbow that bangs on the drums.

The fable will prevail as our heroes travel far.

In this altered universe you're a pest!

Xanthar raised his fist to strike as Lion came in front of the fusion allowing them to ride him and dodging the attack as Stepper summoned his shield journal and pulled from it a mixed blade of Rose's and Dipper's sword.

And when they both save the day, the tyranny will die, so they will swing and sway.

Until the story arc comes to a sudden end, their tale descends into our history.

Lion then jumped high up over Xanthar and while overhead, Stepper jumps off of Lion and raises their sword up as they fall towards the large demon.

Like an eternal eclipse you shine!

And with one down slash, Stepper cuts Xanthar in two as the fusion lands on the ground softly.

The fusion placed their weapon on their shoulder as they looked up the pyramid.

Fully aware, of their next target.

The end.
