This is how the prophecy of Megatron goes in Friendship is Magic (Part 1).
Kup: There you are, Thomas! Override is having a little get-together in the west castle courtyard. You wanna come?
Thomas: Oh, sorry, boys... I've got a lot of studying to catch up on.
Springer: [sigh] Does that tank engine do anything except study? I think he's more interested in books than friends.
Thomas: I know I've heard about the Matrix of Leadership.
[Meanwhile, Ryan is heading to play LEGO Dimensions with Crash Bandicoot when Thomas barges in]
Crash Bandicoot: Hi, Thomas.
Thomas: Hate to interrupt your game, you two. But I need to speak with Ryan.
Ryan F-Freeman: Ok.[to Crash] Beat the Dalek Emperor for me, will you, Crash?
Thomas: Ok. I need to find Predictions and Prophecies.
Ryan F-Freeman: Ok, Thomas. Let's see.[looking at some books] "Legend of Foundation Prime." History of the Dazzlings. [grabs the right book] Aha! "Predictions and Prophecies."
[Ryan pulls out a book and opens it]
Thomas: Thanks, Ryan. You can read it to me.
[Ryan nods and then he starts to read]
Ryan F-Freeman: Matrix of Leadership: See Cybertronian in the Caverns? I thought the Mare in the Moon is good.
[Ryan flips through to the "Cybertronian in the Caverns" page]
Ryan F-Freeman: Aha! Cybertronian in the Caverns, a legend of old Transformer times. A powerful Transformer who wanted to bring Cybertron down. Defeated by the Matrix of Leadership and imprisoned in the caverns of Cybertron. Legend has it, that on the longest day of the thousandth year the stars will aid in his escape and he will bring Cybertron to it's knees using an army of Terrorcons.
Thomas: [gasp] Ryan! Do you know what this means?
Ryan F-Freeman: No. But I might think he will return today.
Thomas: No. It means we have to take a note to Orion Pax.
Ryan F-Freeman: Aye aye, Captain.[pulls out a pen]
Thomas: [clears his throat] Orion Pax,
My continuing studies of Transformer history have lead me to discover that we are on the prohecied verge of disaster.
Ryan F-Freeman:[writing on a paper] Verge... of... disaster.
Thomas: For you see, the mythical Cybertronian in the Caverns is in fact Megatron and he's ready to return to Cybertron. And he will bring it to it's knees with an army of Terrorcons. Something must be done so that this terrible prophecy does not come true. I await your quick response.
Your faithful student, Thomas the Tank Engine.
Ryan F-Freeman: Thomas... the Tank.. Engine. Done. Now I'll do what Spike does.
[Ryan takes a deep breath and blows a flame on the note which transports through the air]
Thomas: Wow, Ryan. How did you do that?
Ryan F-Freeman: [shrugs] But I wouldn't hold your breath if I were you.
Thomas: Oh, I'm not worried, Ryan. Orion trusts me completely.
Ryan F-Freeman: Yup. Twilight's friend Spike taught me that.
Spike: Ok, Ryan. I'm going to teach you how to do this.
Ryan F-Freeman: Ok, Spike. Let's do this.
[The flashback ends]
Ryan F-Freeman: And that's how I learned how to do it.
Thomas: Well, I wish that reply would hurry up.
Ryan F-Freeman: Oooh! I feel like my tummy is running a 1000 mile telethon. And Norm Crosby's going long.[gags] I hope it got here. One second.[coughs] Holy moly. [burps] Excuse me.
[The reply appears]
Thomas: You ok, Ryan?
Thomas: Ok. Can you read what it say please?
[Ryan nods and clears his throat]
Ryan F-Freeman: My faithful student Thomas, I have the letter on what you said. Tomorrow is the day of the Prime Selection. I am going to be there so I'm sending you to a place where you supervise the special prep on the Island of Sodor.
Ryan F-Freeman: But you must stop reading all those dusty old books.
