This is how Arrival of the Dark Spark goes in My Little Pony: Rise of the Dark Spark.
[We see Sunset Shimmer walking when she sees Knock Out alone on the roof over a petrol station and goes up to join him]
Sunset Shimmer: Knock Out, why are you here?
Knock Out: I'm just thinking about an old friend.
Sunset Shimmer: The death of Breakdown is getting to you again, isn't it.
Knock Out: Yes. How did you guess?
Sunset Shimmer: Every Autobot on the team knows that you mourn the death of your former partner.
Knock Out: I know, I still feel sorry for the poor fellow. But thanks for trying to cheer me....
[He is interrupted by a noise and they look up and see a purple comet crash land in the Everfree Forest]
Sunset Shimmer: What is that?
Knock Out: I know what that is. [transforms into vehicle mode] Get in!
[Sunset gets in and they drive off. Meanwhile, Twilight looks out of one of her castle windows and sees the purple comet land in the Everfree Forest]
Ryan F-Freeman: What is that, Twilight?
Twilight Sparkle: It looked like a comet.
Ryan F-Freeman: I don't think comets are purple. Are they?
Twilight Sparkle: No.
Optimus Prime: Then we must check it out.
Twilight Sparkle: It could be a relic.
Optimus Prime: We don't know for certain until we find out.
Twilight Sparkle: Yeah.
Ryan F-Freeman: We could get our friends to find this relic. I'm the Prime-prince of Friendship, Twilight.
[They arrive at the Everfree Forest and see the object responsible for the crash]
Arcee: Down there! It looks Cybertronian.
Optimus Prime: By the Allspark. It can't be.
Twilight Sparkle: What is it, Optimus?
Optimus Prime: The Dark Spark. The opposite of the Matrix of Leadership.
[They see Thunderwing flying toward them]
Optimus Prime: Everyone, Thunderwing isn't here for us. He seeks to gain possession of the Dark Spark.
[Thunderwing lands and furls his wings]
Thunderwing: At last, the Dark Spark is mine!
[Thunderwing grabs the Dark Spark]
Thunderwing: The Dark Spark, created by Unicron, himself.
Optimus Prime: Give me the Dark Spark, Thunderwing.
Thunderwing: And what price will you pay for it, Optimus?
Optimus Prime: That is not a toy to give over. It's too dangerous! You are messing with powers you don't understand. Do the right thing, Thunderwing and simply hand it over.
Thunderwing: How honorable. You really are a Prime. Alas, I see no profit in merely giving you my prize. I decline.
[Thunderwing puts the Dark Spark in his chest. The heroes try to stop him, but Thunderwing stomps his foot to the ground and everything freezes in place]
Thunderwing: Oh, Optimus and Twilight. Can't you see I've already won. [unfurls his wings] You just don't know it yet.
[Thunderwing flies away just as everything unfreezes]
Optimus Prime: [yells angry]
Rainbow Dash: Come back here, you coward!!!
Optimus Prime: I thought this day would never come.
Twilight Sparkle: What's the matter, Optimus?
Optimus Prime: We've just witness a dark legend come to life.
Thomas: What happened? We came as fast as we could.
Optimus Prime: The antithesis to the Matrix of Leadership has arrived.
Ryan F-Freeman: The Dark Spark. And my enemy, Unicron's follower, Thunderwing got it like he own it.
[Suddenly, Evil Ryan senses Thunderwing]
Evil Ryan: At least I can sense him with the blood of Unicron in me.
Ryan F-Freeman: How, Evil me? How can you sense him?
Evil Ryan: I have the blood of Unicron in me.
Matau T. Monkey and Cody Fairbrother: Dark Energon.
[Evil Ryan nods]
