This is how Starscream vs. Galvatron and Ryan goes in Showdown.
[Ryan flies and sees Galvatron confronting Starscream]
Ryan F-Freeman: Hey, King William reject!
Starscream and Galvatron: (together) You stay out of this!
Ryan F-Freeman: Sorry. I don't mean about you, Galvatron. [points to Starscream] Just King Clown here.
Starscream: I'll show you a clown! [blasts Ryan to the ground]
Ryan F-Freeman: Ouch. You have got new power. Why do you want to get rid of Galvatron?
Starscream: Because, Prime-prince, I wanted to be leader of the Decepticons instead of Galvatron.
Ryan F-Freeman: Such traitorous nonsense. I don't think Galvatron would give you the Omega Lock.
Starscream: That is not happening.
Galvatron: Ryan's right, Starscream. He will have the Omega Lock so he could give it to his mentor Primus.
Starscream: So Galvatron has gone soft.
Ryan F-Freeman: I find your lack of understanding the Magic of Friendship disturbing.
Galvatron: Oh please. You can never defeat me and Ryan. Even if you grow a hundred times his size. You were a weakling when I found you and you're a weakling still. Nothing but a sniffling...
Starscream: Spare me your lectures! You know nothing of power!
Starscream: Do you know what real power is?
Ryan F-Freeman: Get to the point already!
Starscream: True power...is simple determination! Making the impossible possible through sheer FORCE OF WILL!
[Starscream releases a wave of force that makes Galvatron and Ryan flinch and knocks the Autobots out of the sky]
Starscream: I have risked everything in pursuit of this power! I have given myself over to it, body and spark! Now witness...the power of one who has SACRIFICED EVERYTHING!
Galvatron: Ha! If you believe that... then you're a bigger fool than I thought! Witness the power of the ones who risks NOTHING!
Starscream: SO BE IT!
Ryan F-Freeman: Maybe I can do this thing. CYBER KEY POWER!!
Starscream: CYBER KEY POWER!
[Starscream's Cyber Key unlocks his cannon and sword]
[Ryan summons his Keyblade and his Cyber Key unlocks his jetpack mounted Waluigi launchers]
Ryan F-Freeman: Prepare to be exterminated, Starscream!
[Galvatron's Cyber Key unlocks his cannon]
Galvatron: Enough magic tricks! Time for some hardware!
[Ryan's Cyber Key unlocks his Requiem Blaster]
Ryan F-Freeman: That's not the only thing that's going retro, sweetheart.
[Ryan and Galvatron fire their weapons at Starscream, but he dodges all of them and even transforms to his jet mode]
Starscream: Is that what you call teamwork and firepower!?
Ryan F-Freeman: What!?
Starscream: Are you seriously trying to threaten me with a pee shooter?!
Ryan F-Freeman and Galvatron: What?!?!
[Starscream transforms to robot mode and shoulder charges at Galvatron and Ryan]
Ryan F-Freeman: [Wilhelm scream]
[Starscream crashes them to a wall]
Starscream: Now this is fire power!
[He fires lasers]
Ryan F-Freeman: [groans] What a ride.
Starscream: So. End of conversation.
Ryan F-Freeman: I saw my time with Darla Dimple flash before my eyes.
Starscream: You'll have to do better than that.
Galvatron: Bravo, Starscream. Your performance is so convincing, I almost want to applaud. [laughs]
Starscream: Oh, how generous of you. In turn, let me give you a big hand.
[Starscream's right arm grows bigger and heads towards Galvatron and Ryan]
Ryan F-Freeman: This is going to hurt. [closes his eyes]
[Starscream's arm punches Galvatron and Ryan into a wall and retracts back towards Starscream and shrinks back to its original size]
Starscream: You know it's pretty amazing when you think about it. With the power I already absorbed, I can increase the mass of my body at will. And soon I will multiply that power a hundred fold.
Ryan F-Freeman: That is quite a HAND-full, Starscream. Here's a little hand me down for you![fires his Requiem Blaster at Starscream]
Ryan F-Freeman: Whoa. You're good but we're better.
[Ryan fires his Requiem Blaster at Starscream, but he dodges]
Ryan F-Freeman: How did you keep dodging!?
Galvatron: Then Ryan and I suppose you'd be a hundred times the fool you are. Right now.
Starscream: Let's do it.
Ryan F-Freeman: Take that!! [uses his magic to push Starscream to a wall]
[Starscream blasts Ryan]
Ryan F-Freeman: [coughs] Shocking. You did think I would surrender to you, Starscream?
Starscream: Why not, Ryan.
Ryan F-Freeman: The only thing I am with Galvatron is that I understand him.
Starscream: So be it.
Ryan F-Freeman: Un guard!
Starscream: Un guard?
[Ryan chuckles then he uses his speed to dodge Starscream's attacks]
Galvatron: What's the matter, Starscream? Can't keep up with the Prime-prince of Friendship with Chuck's speed?
Ryan F-Freeman: For a king that big, you sure are slow!
Starscream: You're the one that's slow! [blasts Ryan]
[Ryan dodges the blast and fires his Requiem Blaster at Starscream]
Galvatron: Go, Ryan!!
[Starscream blasts Ryan, who dodges all but one, allowing Starscream to regain the upper hand]
Ryan F-Freeman: Oh you got me. I'm not going down.
Starscream: Not a chance, Ryan.
Ryan F-Freeman: Now, Galvatron. [high fives Galvatron]
[Ryan and Galvatron fire their weapons at Starscream, but he dodges all of them]
Ryan F-Freeman: Oh come on! You're worse then Rothbart!
[Starscream grabs Ryan and throws him at Galvatron]
Ryan F-Freeman: Tell Odette, I like her!
Starscream: Too much information!
[Galvatron catches Ryan]
Ryan F-Freeman: Oh. Nice catch, Galvatron. Now let's get him. [fires his Requiem Blaster at Starscream]
Galvatron: Thank you, Ryan.
Ryan F-Freeman: Ok, Starscream. Let's dance with the hero who risks NOTHING! Ninja-GO!!!
[Ryan spins at Starscream]
Starscream: [laughs] You make me laugh.
Ryan F-Freeman: [stops spinning] What are you laughing at?
Starscream: I'm laughing at you, Ryan.
Ryan F-Freeman: Good show. Your skills are so good like mine, I really want to applaud.
Starscream: How nice. Prime-prince.
Ryan F-Freeman: I think I am drawing a blank in that one. My apprentice, Matau, got the power of Primus, you got the power of Primus. Anyhow. Nice crown. It's better then mine.
Ryan F-Freeman: That is cool. You and Galvatron need some target practice.
[The two cons fire]
Ryan F-Freeman: Huh? Wait a sec! I didn't say "Use me for target practice"! [flies around, screaming]
[Ryan flies past Starscream then the rockets blow up]
Ryan F-Freeman: Sorry! Matau did like you as a friend because of his power and friendship.
Starscream: Sure. I know you do think that Darla Dimple and Sora got ties to you. If you know what power you got.
Ryan F-Freeman: I know OpThomas Prime told me this. And I know that I have something that is the same as your power. The friends I meet. I become a part of thier heart and spark. Just like they become a part of mine. I risk nothing for this thing. My friends are my power and I'm thiers!
Starscream: You mean... you know about power?
Starscream: Thus endeth the reign of Galvatron.
Galvatron: How can this be... are we... to be defeated... by Starscream?
Ryan F-Freeman: No.... I will not be defeated... I will never give up. Even my last breath.
