The most extreme Rwby crossover ever. When Ultra Instinct Shaggy accidentally arrived in Remnant and was found by Ozpin. He is given an offer by Ozpin . He must protect all the students from harm and also defeat Salem. But he soon discovers the dark...
(Imagine that Shaggy is holding William in his arms.)
Shaggy: Why is she attacking us?
William: I believe she is after Ozpin. She'll do anything to get to him.
Scooby: Then we shall defend this Academy.
Both shaggy and scooby go ultra and they prepare themselves to fight. But a sudden flash of pink light caught there attention. William had turned into this:

He looked at Shaggy and smiled his teeth were wicked sharp and his left arm was larger than his right.
William: Hello dear shaggy. My name is AFH better known as cryo. I am William's ultra form.
Shaggy: Like, nice ta meet ya Cryo. Are you ready for this!!
Cryo responded with a ear splitting roar, causing all the Grimm to look in that direction. All the people of Remanet heard this roar.
Scooby: Well, let's get to work.
They all attacked the Grimm. Shaggy slammed his fist into the ground causing it to split open and all the Grimm fell into it. Cryo was flying overhead smacking all the nevermores out of the sky with his over sized arm.
Scooby was also dealing a huge amount of damage to the Grimm. A huge goliath then stampede towards Scooby but was launched into the air.
As this pointless battle wagged on, Salem stood in the distance, watching as her Grimm were being swatted and crushed like insects.
Salem:Those three men are laying waste to my Grimm.
Then team CVFY showed up aswell as team Rwby. They watched in awe as Scooby,Shaggy and William killed the Grimm without breaking a sweat.
Salem then teleported right behind Shaggy and was about to drive a sword through him but when she tried to stike, Cryo appeared and was stabbed through his heart. Shaggy noticed this and caught William as he fell to the ground. William was bleeding badly as shaggy held him in his arms.
Shaggy: William why did you do this? Why did you save me?
William: Because I....see a hero, always ready to do the right thing.( coughs up blood and his heart was beating slower)
Shaggy: William please... Please don't do this.
William: Goodbye....dear...friend.
And with his final breath, William passes away and falls limp in his friend's arms.
Shaggy:No!!!!(crying)
Scooby stood behind his friend and placed his hand on Shaggy's shoulder. He could see that William and Shaggy were best friends.
Salem:Foolish mortal, he died for nothing.
Shaggy then roared and began to transform once more but into something more powerful. Steam erupted from the ground and engulfed Shaggy and he began to grow until he became this. He stood over 4000 feet tall, much taller than Beacon's main tower. His eyes shone with immense power and his hair was now pure white.
This is Shaggy's God form. He looks at Salem and roared so loudly it shattered every window on the planet. He glared at Salem and let out another roar and brought his fist down. Salem tried to stop his strike but couldn't.
