This is how Revisit Ninjago World and Defeat the Overlord goes in Ryan's Quest 2.
They are back in Ninjago City and they saw the Heartless attacking the People
Ryan: Looks like there's trouble.
Sora: Let's go!
They went off and they saw Jay and the others.
Jay: Oh. Dora and Brian. You're here!
Sora: That's Sora!
Ryan: And Ryan! Get it right, Jay!
Jay: Oh. I get it. Sora and Ryan!
Ryan: Alright! Alright!
They are fighting the Heartless and they defeated them
Ryan: That was close.
Sora: Yeah, but those Heartless re different to us.
Zane: Yes. The Overload is using them, and he came back to life thanks to Exon.
Jay: We got rid of him, but he still come back to Ninjago. And we have to find him and the Overload.
Sora: Let's go!
They went off and they found him and the Overload
Exon: At last. Sometime that Ryan and Sora have arrived for the single moment.
Crash Bandicoot: Ok, Exon. You mind to take that hood off?
He takes off the Hood and his head looks like Dr. Neo Cortex
Exon: So you're here to stop our Plan.
Ryan: That's right! If you were trying to make Kingdom Hearts, we'll stop you!
Exon: If you want too? Then fight us!
They are fighting him and the Overload and they defeated them
Exon: Oh... This is a most epic battle I had.
Then he's fading away
Exon: We will meet again, Crash Bandicoot. Wait. Did I just say that? Never mind. Take care of Ranyx and Roxas for me, Sci-Ryan.
Sci-Ryan: What a weird guy.
Evil Ryan: I don't understand who Roxas and Ranyx is.
Sora: But at least we got rid of him.
Jay: You're journeys not end yet?
Jay: Well, just be be careful from danger.
Sora: We will. Bye.
