Anonymous: Hey, have you tried this prompt; The Owl House/BATMM Xover, where Crusher and Blaze are sons of Lilith Clawthorne, both made by magic, (with Blaze being made with the magic of the demons and Crusher with the magic of the Titan) but they've been separated thanks to Belos, who wants to use their magic (mostly Crusher's) for his own purpose then Grom tries to take over Axle City one day, and one way or another, they discover each other?

The screams of the monster machines echoed through the streets of Axle City. The huge beast known as Grom slithered through the road, targetting each truck to be his next victim.

How the being managed to slip out from the Boiling Isles to the world of the monster machines, no one will ever know. All they knew was that everything had been fine, a pretty ordinary day in Axle City (or as ordinary as things were, anyway) when a door suddenly appeared in the middle of the street, and out came the creature made of goo, aiming to spread fear and nightmares all throughout the town.

No one knew how to stop the being.

No one but three.

Blaze KNEW that the day was gonna turn for the worse.

By the morning light on the sunrise, he felt a surge of familiar magic, familiar WITCH magic, fill into the air. AJ had felt it too, but they had shrugged it off, thinking it was typical and that perhaps Axle City had witches.

Apparently, they had been mistaken.

After winning the race that morning, they had caught a glimpse of a being in a mask, watching in the crowd. It had caught them off-guard, but no matter how hard they tried, HE was still there.

Emperor Belos, the most powerful witch of all the Boiling Isles.

The sight of him left them frozen before they dashed out of the Monster Dome. Their friends had caught up to them and asked them questions, whether they were alright or not. AJ couldn't look at them in the eye without shuddering. Blaze gave them one glance, but he diverted his gaze immediately as the memories came flooding in, blinding him with despair.

The memories of what Belos did to his family. Almost petrified his aunt Eda and mother Lilith. Tried to kill his human cousin Luz and their friends. Hunted down his grandmother Diana. Managed to actually kill his little brother Dynamite.

And when he thought things couldn't get any worse, Grom came moving in.

"Let's head inside to hide!" Gabby called out as she and Watts zoomed towards Gabby's Garage.

They all followed after them, slamming the doors shut. Zeg, Stripes and Darington huddled together, scared of what was happening outside. Starla was holding Watts while Gabby listened in on the news. AJ dismounted from Blaze's driver seat and exchanged a worried glance with his best friend.

"Blaze, what do we do?" he whispered to him.

"I... I don't know," Blaze hissed. "Last Grom, it was Luz and Amily that defeated him. I couldn't even get to Grom because of Dynamite's death. I don't know how she managed to defeat him,"

"And I was still young back then to remember what Gus told me about it," AJ sighed. "How do you think it got here?"

"I... I have some theories," Blaze growled, remembering the sight of Belos in the crowd. "but let's not focus on that. Let's focus on how are we gonna get Grom out of Axle City... without using Witch Magic,"

"Blaze, we'll have to tell them sooner or later," AJ frowned. "They'll find out sooner or later, anyway,"

"I know, I know..." Blaze sighed. "but how would they react?"

"There wouldn't be a choice," AJ tried to reason out. "If anything could beat Grom, it's Witch Magic,"

"I..." Blaze swallowed. He hated to admit it, but AJ was right. They had no choice. Grom was too powerful for their powers and abilities alone. They needed help, and only he and AJ could provide that kind of help.

Only THEY can wield THAT kind of magic.

"You... You're right," Blaze let out a sigh of defeat. "We should tell them,"

But just as he turned to talk, a huge boom came from the front. They turned and yelped as the door was destroyed by Grom, who seeped in like goo before rising up and glancing over at each of them dangerously. Everyone gasped, jumping back in fright as Blaze exchanged a worried glance with AJ before making their way to the front to protect their friends.

This day just couldn't get any worse now, could it?

Crusher should have known that the day was gonna be chaotic.

On one hand, he had already felt the strong surge of Witch Magic that morning, but on the other hand, he thought that it was just a coincidence, or that Pickle was practicing the spells that his Grammy was teaching him with his wand. He didn't expect it to be something as bad and as big as this.

It all started with the race that morning. He was trying to cheat again when he saw a familiar masked face in the crowd. It had caught him off-guard, which prompted him to slow down slightly and lose focus, prompting Blaze and AJ to win the race (but they would have won anyway, so eh). After the race, he had looked over to find the being darkly glancing over at him and the other racers.

With glowing blue eyes from within the mask, in which he had only seen from one person. Or one witch, more specifically.

Emperor Belos, the most powerful witch of all the Boiling Isles.

The familiar sight made him shudder before he fled out of the Monster Dome. Pickle followed after him, and they managed to head back to their shared apartment with no delay. Once they were alone, he managed to tell the green truck about the familiar face.

They were just about ready to call Crusher's Grammy when the attack happened. Grom was destroying the buildings and chasing around monster machines all through the city.

Crusher was horrified at the sight that he and Pickle saw from the window. He sent Pickle off to his Grammy to warn her through magic then he dashed out to check out the situation.

He could barely remember when he last saw Grom. He and his older brother Spitfire were suppose to go to Grom with their human cousin Luz and her friends when Belos attacked them just a week before and killed him. Even he couldn't believe that he was succesfully killed before being ressurected just a day later to be used as Belos's little magic battery and little puppet toy.

The memories made him shudder. Thank the Titan that his Grammy rescued him before he lost it completely.

But now, here was Grom, destroying the city he had learned to blend in. The city he had hid in for 6 years already, with Pickle, whose family had found them and helped them hide out from Belos.

He suddenly heard a crash, and he turned to see Grom destroying the door to Gabby's Garage. His eyes widened as the other racers let out a scream of fright while he watched Blaze move front to defend the others.

'As if he can.' he shook his head before driving forward towards Grom, circling his tires to ready a spell.

Just as he did, Grom turned away from Blaze and aimed to attack the others. It aimed for Darington, one of it's goo entering the stunt truck's mind, which caused his eyes to disappear into glowing white. He let out a scream, and everyone around them gasped.

"DARINGTON!"

Crusher prompted to stop, eyes wide as he watched Grom retract before shifting into the shape of the stunt truck's greatest fear. The goo shifted into a crowd of masked monster machines, who all started laughing at Darington mockingly, calling him cruel names and insulting him for being a reckless, stupid racer and that he didn't deserve to be cared or loved.

'Damn worst fears.' the dark blue truck shook his head.

By then, Darington started to cry. Blaze moved to hug him and gently comforted him. The others did too, in attempt to block out Grom's mockery and insults, no matter how loud it got. Crusher sighed and proceeded to drive forward to challenge Grom when Blaze slowly pulled away from Darington to face Grom once more.

"ENOUGH!" he yelled out. "Leave my boyfriend alone!"

The whole place seemed to have shaken at his outburst. Crusher was taken back in surprise.

He had never seen Blaze so mad before. Well, he HAS, but it was only once, and even then, it wasn't THAT frightening. It had also been to defend Darington (no surprise there) when he had kicked him out of his own stunt, but back then, he still calmed down fine.

But now, it seemed that he was fueling himself with his rage. His eyes were glistening red while his whole body seemed to glow red. His tires were glowing a fiery shade of orange as well as a magic circle moved around him while he gritted his teeth and glared up at Grom.

Crusher's jaw dropped. Wait, was he...? No, that can't be. It's not possible!

But it was. It was right in front of him, so it couldn't be a fraud.

But... how? How was Blaze using... Witch Magic? Where did he learn it from?

Or... was he a witch the whole time? Because by the looks of the magic he's using, it seemed that he was using his rage to fuel the magic inside of him.

But then... how did he get here, to Axle City? Was he also a Wild Witch? Did he escape from Belos too? Is he the only other one that came here?

Just as the questions flooded into his mind, a familar voice snapped him out of his thoughts.

"ABRA-KA-PICKLE!"

Grom let out a screech as a blast of magic hit him. Everyone turned to see Pickle with his wand aimed at the creature, expression worried and serious as he drove forward, going in between Blaze and Grom. The red truck was taken back by the green truck's presence while Grom snarled and shifted it's form back into goo, aiming to target him. Crusher gasped.

"PICKLE, LOOK OUT!"

Pickle seemed to realize what Grom was aiming to do and gulped. Blaze looked like he was about to take the hit when Crusher beat him to it. The dark blue truck zoomed in front of his boyfriend, shutting his eyes and yelping as he felt Grom enter his mind.

Everything else around him turned black.

Blaze, AJ, Pickle and everyone else watched in horror as Grom entered Crusher's mind. Out of all of them, Crusher was the one they least expected to take a hit like this, especially on a huge monster wanting to spread fear and nightmares.

"CRUSHER!" Pickle tried to rush over to save his best lover, but he was swatted back by Grom.

"Pickle, get back!" Blaze called out, pulling the green truck back.

"But-! But Crusher-!"

"We can't get him off that easily!" AJ told him.

"But- wait," Pickle turned to them oddly. "How do you guys know this?"

"Pickle, we'll explain later. To all of you, promise," Blaze told him, glancing over at the others too before taking the front again. "For now, we need to defeat Grom. It's the only way we can get rid of him,"

AJ nodded and took a step front beside his best friend before gasping as they watched Grom shift it's shape once more. The shape grew in size then it formed into a shape of a familiar looking witch...

"What...?" Blaze blinked up to see the features of the witch, it's curly, fiery red hair familiar as his eyes glowed full orange.

["You are PATHETIC!"] the creature spoke through the figure's mouth before cackling. ["To think that I actually cared about you! You BETRAYED ME! How DARE you?!"]

Blaze and AJ exchanged a glance of confusion. They then turned to Pickle, who gasped and looked as if a big secret had been brought out. His expression made them worry and turn to Crusher, who hissed as he heard the voice.

"I..." the dark blue truck was starting to breathe heavy, tears strolling down his cheeks as he trembled. "I'm sorry, I-"

["AS IF SORRY IS GONNA ERASE THE YEARS OF MOURNING I HAD FOR YOU, DYNAMITE!"]

Blaze froze at the name. 'Dynamite...?'

Pickle tensed at the name with a gulp. AJ glanced at his best friend with concern as he watched the red truck move closer.

["YOU SHOULD HAVE STAYED DEAD!"] the creature snarled. ["BELOS NEVER SHOULD HAVE BROUGHT YOU BACK! YOU'RE BETTER OFF DEAD! I'M BETTER OFF WITHOUT YOU EXISTING!"]

Those words made Blaze stop. The horror he felt was immediately replaced with rage, his whole body flaming up as he trembled. The tears he had been trying to hold back were falling, but they quickly evaporated in the flames of his anger as the fiery circle below his tires returned.

How DARE Grom do this?! He had NO right, no matter if this was the worst fear or not.

"Blaze!" AJ cried out towards him, but he didn't bother to listen.

He couldn't listen. His heart was pounding, his head was full of rage, and his sanity was slipping.

Because after all these years, even after watching the other die right in front of him, even with how confused he is right now on how it was possible, he couldn't let Grom do this to him.

He couldn't let Grom torture his little brother with an image of his witch self.

"Guys, get down!" AJ told the others, raising his hands up and ready to cast the spell as he watched the flames appear all around his best friend.

"AJ, what's going on?!" Gabby demanded. "What's happening to Blaze?!"

"No time to explain!" AJ shook his head and took off his helmet, revealing his now pointy ears. "We need to get back! Now!"

He took a deep breath and circled his hand around, creating a magical circle in the air before he tossed it in the air. The circle enlarged and surrounded the friends, forming a force field around them. The group gasped.

"Woah..." Darington's jaw dropped. "How'd you do THAT, AJ?"

"Same way Blaze is able to do... that," AJ pointed to the front, and they all watched as Blaze disappeared in a burst of flames.

They gasped as the flames slowly disappeared, and in their friend's place stood a witch teen, about 19 years of age, with curly, flamy red hair, ocean blue eyes, and pale white skin, similar to the large form in front of them. He glared dangerously at Grom and raised a hand, allowing fire to burst out of his claws while his boots burned with his own flames.

"GROM!" he roared out. "LEAVE HIM ALONE! NOW!"

Grom let out a roar and attacked the witch, but Blaze was prepared. He clenched his flaming hand and dashed towards the creature. He jumped over the being and proceeded to cast his spells. Each spell he casted caused his eyes to glow in orange as he dashed from left to right and all around, waving his flaming hands again and again. Grom cried out in pain and tried to fight back, but Blaze was faster, and before he knew it, he had reached Grom's center with his flames, causing it to explode with a boom.

As soon as it did, the connection to Crusher's mind snapped, and the dark blue truck fell on the ground, wheezing in pain. Pickle gasped.

"Crusher!" he drove towards the other as fast as he could.

"Pickle, wait!" AJ cried out to the green truck. "The force field-!"

But Pickle didn't hear him. He, however, remembered the force-field and used his wand to rip a hole to drive through before taking his lover into his tires.

"Crusher! Crusher, wake up!"

"P-Pickle...?" Crusher coughed, looking up at the green truck with concern. "Wh-What happened...? Where is...?"

"Dynamite...?"

Crusher tensed at the familiar voice and the spoken name, his eyes widening in horror. He turned to find himself staring straight at the one witch he had never thought to see again.

"S-Spitfire...?"

Blaze's eyes widened. So... it was true. Only one person other than AJ could recognize him and say his name. One other person he knew and loved.

His brother. His little brother. The only one he had and the one he thought he had lost in the hands of Emperor Belos.

Crusher felt his magic surround himself as the tears began to roll down his cheeks. His magic was a lightning blue, surrounding him in a white flash. As soon as it ceased, in his place stood another witch teen, about 17 years of age, with straight midnight blue hair, coal black eyes and pale white skin. He was a few centimeters shorter than the other, even with the boots as his electric blue magic faded into the air.

Blaze was in tears already, but seeing his little brother in front of him, standing right in front of him, alive, breathing and using his magic made him break down more. He couldn't control his feet, and he was soon running to the other, ignoring the flames that burst out from under his steps. He took the other into his arms, squeezing him into an embrace.

Crusher was taken back by the sudden hug. He had expected the other to yell at him, to scold at him, to scream and shout. To demand why he had never told him where he was or that he was alive.

But he didn't. Instead, his older brother was embracing him, holding him in a hug he had thought he was never gonna receive again.

And he couldn't help but return it.
