This is how Legend of the Dark Sparkle goes in My Little Pony: Rise of the Dark Sparkle.
[We see a statue of Optimus Prime holding the Element of Magic]
Optimus Prime: (voice) The Element of Magic, the most powerful Element in the Elements of Harmony, grants the wielder the wisdom of the Alicorns.
[We see a statue of Megatron holding the Dark Sparkle]
Megatron: (voice) But for every force in the universe, there is an equal and an opposite. For every matter, an anti-matter.
[We see the Dark Sparkle]
Optimus Prime: (voice) Legends speak of the Dark Sparkle: the antithesis to the Element of Magic.
Megatron: (voice) Where the Element of Magic powers the other Elements of Harmony, the Dark Sparkle empowers its wielder to bend the very fabric of a planet and its inhabitants to their will.
[We see Cybertron]
Optimus Prime: (voice) This is our darkest hour. Cybertron has nearly fallen and the Autobots are on the verge of defeat.
Megatron: (voice) This is our finest hour! Cybertron is nearly ours and victory is finally within the Decepticons' grasp!
[My Little Pony: Rise of the Dark Sparkle]
[We see Shockwave and Starscream flying through Crystal City]
Shockwave: The gates of Crystal City lay beyond this chasm.
Starscream: Tell me, Shockwave. Do you believe this "Dark Sparkle" even exists?
Shockwave: I do not believe, Starscream: I hypothesize. My conclusion is not yet formed, but all data leads us here.
Starscream: Ah yes, ever the scientist.
Shockwave: As you once were.
Soundwave: Conversation irrelevant, danger imminent.
Starscream: For once we agree, Soundwave.
