This is how Stephen goes to battle in Stephen and the Scraplets.
[Outside, Soundwave and the Scraplets arrive at a junkyard]
Soundwave: Chew every last bit of metal you can find. Chomp it down to the last bit of scrap.
[The Scraplets start chewing on the metal. Then, Soundwave is hit on the head by hundreds of ice cubes]
Soundwave: What in the AllSpark?!
[He then looks up and sees Stephen and Blue Dragon approaching]
Stephen: [jumps down from Blue Dragon] Soundwave!
Soundwave: And just who do you think you are?
Stephen: My name is Stephen. And I am here to stop you.
[Stephen takes out his sword and charges at Soundwave. Soundwave transforms and attacks and the two get into a big fight]
Soundwave: Die, Trainbot. [throws a punch]
Stephen: Never! [swings his sword]
[Blue Dragon sprays extremely hot water at Soundwave. The others arrive aboard the Nemesis to see what is happening]
[The battle between the two bots continues until Stephen receives a blast in the chest from Soundwave. Soundwave then takes a sword and stabs him]
Pinkie: Stephen! [thinks for a moment] Wait here! I'll be right back! Ratchet, get a Space Bridge to the Shadowzone open!
Ratchet: You got it!
[Stephen continues to battle Soundwave, even though he is injured. The fight gets more firm until Soundwave throws a final blast at Stephen, killing him]
Thomas: Stephen's... gone.
Twilight Sparkle: Even without him, we can still defeat Soundwave!
[Pinkie soon arrives back at the Junkyard, having gathered all the metal she can]
Blue Dragon: You dirty...
Soundwave: [evil laugh] Not even your brave Trainbot knight can stop me.
Blue Dragon: [roars a stream of boiling hot water at Soundwave]
Soundwave: AAAAAAAAAAAAAAAARRRRRRRRRRRRRRGGGGGGGHHHHHHHHH!!!!!!!!! Hot! Hot! Hot!
Thomas: Serves you right for killing Stephen.
Blue Dragon: [then he roars out freezing cold water]
Soundwave: Cold! Cold! Cold! Freezing! Freezing!
Rainbow Dash: Keep going, Blue!
Applejack: Yeah! Show that bad bot some manners.
Thomas: [goes over to Stephen's corpse] We will never forget you, Stephen.
Ratchet: Perhaps Soundwave killing you didn't mean the end of your life. But it turned out to be the beginning of a greater journey.
Scootalooo: But, we can't just leave him like this!
Ratchet: I know we can't, Scootaloo. Knock Out, take Stephen to the Nemesis medical bay and hook him up to a life support machine.
Knock Out: You got it. [runs off carrying Stephen]
Pinkie: Ratchet, open the Space Bridge to the Shadowzone.
Ratchet: Way ahead of you. [Opens the Space Bridge to the Shadowzone]
[Soundwave tries to run off but Blue Dragon stops by spitting ice cubes all over the ground. Soundwave trips and falls]
Blue Dragon: [starts laughing at Soundwave]
Soundwave: You little blue ice cube spitting moron! It's not funny!
Blue Dragon: Well, it is to me. [continues laughing at Soundwave]
Soundwave: [throws a punch in which Blue Dragon dodges]
Blue Dragon: Is that all you've got? [roars out a stream of extremely hot water]
Soundwave: Stop that!
Thomas: Now, Pinkie!
Pinkie: [throws the metal through the Space Bridge]
Scraplets: [chase after the metal]
Scraplets: [continue to chase the metal into the Space Bridge]
Soundwave: You fools! WHAT ARE YOU DOING?!!
Ratchet: Couldn't fall for a last minute trick, could ya, Soundwave?
Soundwave: [growls, follows the Scraplets] Stop, you idiots!
Pinkie: Going, going... [watches Soundwave disappear into the Space Bridge]
Ratchet: [closes the Space Bridge] Gone!
Percy: We did it!
James: But right now, we've got Stephen to worry about!
Thomas: To the Shadowzone!
[the team bridges through to the Shadowzone]
Percy: It's spooky here.
Pinkie: It's okay, Percy. They say that the zombicon SkyQuake used to haunt this place.
