[They fire at the Cult members]

[Quintessa screams and disappears]
Matau T. Monkey: I float like a butterfly.

[Kuryan sprays some perfume at Mary]
[Ryan hugs Celestia]

Ryan F-Freeman: Cause I am a hero like your uncle. My friends are my power and I am theirs.
[Scrappy-Rex transforms back into Scrappy-Doo as the souls go back into the peoples' bodies and demons come out. Evil Ryan pulls on the string and a disco ball shines bright along with Kuryan's gun, Hot Rod's mirror and lights, Umarak's Lightning McQueen's lucky sticker, and some mirrors]
[The demons blow up]
Ryan Tokisaki: We did it! We did it!
[Crash dances his victory dance with Umarak]
[Scrappy puts up his fists]
Scrappy-Doo: Come on, I can still take you. Put them up.
[Maticus grabs Scrappy]
Scrappy-Doo: Is that all you got?
Maticus: I guess you are under arrest.
Ryan F-Freeman: Don't worry. The police could give you a home.
[Umarak and Kuryan hear banging and go over to a hole and open it and find the real Emile Mondavarious]
Umarak the Hunter: Mondavarious is that you?
Emile Mondavarious: Yes.
Kuryan: How did you get in there?
Emile Mondavarious: Two years ago, that little pest turns up at a casting session for our evil elves. The next thing I know, I'm stuck in a hole and he's cavorting about in a mechanical version of me.

[Ryan gives the pyramid to a police officer]

Fred: It all started when I was giving a speech on my new book... [looks at Velma] And uh, I really think the Velmster should take it from here.
Velma: Ok. Through the combined power of the relic, Scappy tried to make himself all powerfull.
[Ryan puts the dog carrier to the helicopter ]
Scrappy Doo: Oh get over it. So I got a little cranky.
Crash Bandicoot: Shut up, puppy. There's only two heroes who have power. [to Ryan and Twilight] If you catch my drift.
Scrappy-Doo: And I would have got away with it too, if it weren't for you meddling other worldly sons of a...
[Crash closes the door and Scrappy's voice is muted]
[Everyone cheers for our heroes]
Ryan F-Freeman: Crash is good. At least Quintessa is gone after what she did to us.
Twilight Sparkle: Yes. And we did it with the magic of...
Matau T. Monkey: Yeah! Friendship! Heroes and ponies and robots and stuff.
Ryan Tokiskai: Thanks, Umarak. For saving Mystery Inc.
Umarak the Hunter: Your welcome. Thanks for believing in me and Ryan.
[Ryan looks at the sky as the helicopter flies off]
Ryan F-Freeman: [narrating] With some new and old allies, we saved everyone from the demons and Quintessa. And the future will be a bright one. I am Prince Ryan F-Freeman Prime, friend of Princess Twilight Sparkle. And I send this message, so that our time with Scooby and the gang will be forever as time goes on.
