This is how Optimus, Twilight, Spike, Starlight, and Rocka vs. Black Phantom goes in The Cutie Re-Mark Part 2.
[Black Phantom arrives in the time Rainbow Dash performed her first sonic rainboom]
Black Phantom: Ah, here we are.
[He hears Rainbow Dash's young, filly-like voice near by]
Black Phantom: That's my que.
[Black Phantom prepares to make his move when Twilight, Starlight, Spike, Optimus, and Rocka appear]
Black Phantom: Well, well, look who's come to save the day.
Twilight Sparkle: We're here to stop you, Black Phantom.
Starlight Glimmer: You won't get away with this.
Spike: The space-time continum is going to return to normal.
Optimus Prime: And there is nothing you can do about it.
Rocka: Especially with a new teammate.
[They start fighting]
[Black Phantom stands above Twilight and aims his sword half of his Razor Sabre at her]
Black Phantom: Now I will destroy you, Sparkle. As I destroyed your Magic of Friendship.
Twilight Sparkle: It's Twilight Sparkle!
[She blasts him]
[Black Phantom holds Twilight by the throat and is at the edge of the cloud he's standing on]
Starlight Glimmer: Let my teacher go!
Black Phantom: Starlight Glimmer, this is why only fools are heroes. Because you never know when some villain will come along with a sadistic choice. Rule with me or your teacher meets her little purple end. Make your choice, Starlight. And see how a hero is rewarded.
Starlight Glimmer: Don't do it, Black Phantom.
Black Phantom: We are who we choose to be. Now choose.
Black Phantom: Tick-tock, Starlight. We don't have all day. The portal to the present will be closing by itself in less than an hour. So what is your answer?
Starlight Glimmer: No.
Black Phantom: What?! Your teacher, your friends, the present. Lost to you forever. Can you not see what I am about to do to her?
Starlight Glimmer: Yes. But I have also seen what you have been able to do here without your comrades.
Black Phantom: What?!
Starlight Glimmer: I've been spying on you.
Black Phantom: And now you know what we are capable of.
Starlight Glimmer: Yeah.
Black Phantom: I should've known you were up to something.
