This is how our heroes arrive in the Transformers: Prime world in Ryan's Quest 2.
Ryan: So this is your world. Must be great to be home. Huh. Well?
Crash: You know, something isn't quite right here.
Sci-Ryan: Yeah, something's wrong since we left.
Goofy: I wonder what happened to your world?
Matau: I wonder what happened?
They saw Codylight, Acree, Carmelita and Thunderblast coming
Codylight: You're back! We have a major situation!
Acree: The City is under attack from Megatron!
All: What!?
Carmelita: Come on, we have to stop him!
They went off and they found him
Megatron: Looks like you're here.
Ryan: Megatron, what are you doing now?
Megatron: My Plan is to rule this world and enslaved the humans.
Sora: We won't let you do this.
Megatron: Really, well, fight me.
Then he heard a ticking noise
Megatron: Huh? That sound..
He saw Brain the Crocodile
Megatron: [screams] Oh no! Not again! Stay away form me!!
They are fighting him and they defeated him
Ryan: Listen, Megatron! We will spare if you reform us, if you didn't we will feed Brian the Crocodile.
Megatron: I'll reform later. Goodbye. [transforms into jet mode and flies off]
Ryan: Good, that's more like it.
Minutes Later
Ryan: Now where is the keyhole?
They saw the Cube glowing, Sora and Ryan unlocked a new gateway
Codylight: Huh? What is with the bright light?
Sora: A New pathway is opened.
Sci-Ryan: Codylight. Everyone, we'll be back after we find Optimus, Bumblebee and Zig.
Codylight: Ok. Good luck, Prince Ryan, Crash, Sora, Evil Ryan, Evil Anna, Bertram, Donald, Sci-Ryan, Matau and Goofy.
They left this world
