Scoob!2020

[when Scooby, Shaggy, Mystery Inc. and Falcon Force defeat Cerberus by using the Rottens as bowling balls to make it slip and fall back into the realm of the Underworld]

Shaggy:
Man, looks like we just spared the world!

Scooby:
[chuckles] Bowling puns!

Shaggy:
[he and Scooby fistbump] This is so us!

[Everyone shuts the gate to the Underworld, trapping Cerberus]

Shaggy:
OK, so how do we lock that puppy up? [Velma, Daphne and Fred look at each other, then at Scooby and Shaggy, worriedly] What?

Velma:
One of you has to hold the gates shut here…

Daphne:
…while one of you locks them from… inside the Underworld.

Shaggy:
[distraught] What? No! There has to be another way. Right, Velma?

Velma:
Alexander the Great built these gates to be locked only by him… and his dog, Peritas. As the last descendant of Peritas, Scooby has to do it.

Daphne:
But the prophecy says he needs his best friend to help him.

Fred:
That's you, Shaggy.

[Shaggy and Scooby look at each other, before the latter looks towards the gate with the rotating lock with a handprint and pawprint on two different sides. Scooby then looks on in determination and courage]

Scooby:
There's no other way. I'm the key. I'll go.

Shaggy:
No.

[Scooby then makes his way to the gate, with everyone looking at him gloomily; he then stops by the lock, as he prepares to place his paw on it, but all of a sudden, Shaggy slaps the two-sided lock, flipping it to the handprint side]

Shaggy:
It says one of us had to be on the inside, but it doesn't say which one.

Scooby:
[worried] No!

[Scooby flips the lock back to the pawprint side, making Shaggy gasp; both Shaggy and Scooby then flip the lock to either the handprint or pawprint sides of the lock, before Shaggy stood in front of it when it was turned to the handprint side, which Scooby accidentally slaps him multiple times to prevent him from touching the lock]

Shaggy:
[grabbing Scooby's paw and calming him down] Buddy, back when we were kids, you saved me. Now it's my turn. [then places his hand on the lock's handprint side, activating the gate in which Shaggy then disappears]

Scooby:
[horrified] No! Don't! Raggy, wait! No!

[Scooby gasps, after the gate to the Underworld then locks, before Shaggy appears on the lock from the other side of the gate, then saddened]

Scooby:
Raggy.

Shaggy:
Scoob, you're the best friend I could ever ask for. [sighs] And you always will be.

[As the gate completely locks, Scooby whimpers as he watches the lock's reflection of Shaggy dissipate, turning into a glowing green lock of the pawprint; Scooby then saddenly places his paw on the pawprint, which makes the entire gate as well as the entire ancient temple to vanish back into the temple's present state; Scooby then whimpers and then starts sobbing, howling and mourning the loss of his friend. The gang comes over to him and gives him a comforting hug as themselves and the Falcon Force grieved about Shaggy as well.]

Scooby:
[sobs] Raggy... [Daphne, Velma and Scooby sobbing]

Velma:
Are we missing something? "A pair whose friendship forever grows." [wipes her eyes] Does it mean something else?

Daphne:
[looks Scooby in the eyes] I think it means that Scoob and Shaggy's friendship will live on... whether they're together or not. [hugs Scooby]

Velma:
But...why would Alexander make a gate that would separate him from his best friend forever?

Fred:
He must have built a way out.

Daphne:
[looking behind Velma] Uh, guys?

[A statue of Alexander the Great and Peritas magically appear in front of the gang]

Velma:
It's Alexander the Great. Look at this inscription. It's a message from him. "Our bond will never break or bend..."

Dynomutt:
"...so, my friend, it's time to return home."

Velma:
Maybe Scooby should give it a try.

[Scooby walks up to the statue and sadly looks at it]

Scooby:
Raggy, you promised you'd never leave. Come home.

[A door magically unlocks and opens to reveal Shaggy, who is unharmed]

Scooby:
Raggy?

[Cerberus's paw kicks him out and closes the door as the statue disappears]

Shaggy:
Zoinks! I guess friendship really did save the day.

Scooby:
[relieved] Raggy! [laughs in joy]

Shaggy:
Scooby-Doo!

[Scooby runs up to Shaggy and hugs him as do the gang]

Daphne:
I love you guys!

[Dee Dee laughs]

Daphne:
You gave us quite a scare, Shaggy.

[Shaggy takes Scooby's collar out of his pocket and puts it back on Scooby's neck as Scooby himself smiles]

Shaggy:
Well, it takes more than a 3-headed monster to keep me away from my best bud.

Velma:
Tank, empath, brain. I finally figured out what you guys are. You're the heart of Mystery, Inc.

[Scooby licks Shaggy as the Falcon Force look happily at them and Dynomutt licks Brian, which he exclaims in pain]

Dynomutt:
Sorry. Metal tongue. Shoulda thought that through.

Dastardly:
[angrily] Put me down, you traitorous tin cans!

[Two flying Rottens, who had captured Dastardly and Muttley, lower them in front of the gang]

Muttley:
Rasm-Frasm. Stupid robots!

Brian:
Time for you to pay for your crimes, Dick Dastardly.

Shaggy:
Or is it? [pulls off a mask revealing…]

All:
Simon Cowell?! [Muttley growls angrily at him]

Daphne:
Wow, that is a solid impersonation.

Simon Cowell:
Thank you. I also played Rum Tum Tugger in my secondary school's production of Cats.

Velma:
This makes no sense. How could he have time to judge the world's greatest talent shows and build a giant airship? [pulls off another mask to reveal he is really… the real Dastardly!]

All:
Dick Dastardly?!

Dastardly:
Drat! No one ever goes for the double unmasking. [Muttley snickers as Dastardly frowns at him]

Brian:
[to Dastardly] You are coming with us.

[The Falcon Force carry Dastardly and Muttley away to custody]

Dastardly:
I would've gotten away with it, if it weren't for you MISMATCHED MEDDLING MISCREANTS!

Fred:
Congratulations, you two. You just saved the world.

Daphne:
How do you feel?

Scooby and Shaggy:
Hungry.

[The gang laugh]
