This is how Defeating Black Phantom goes in Princess Twilight Sparkle Part 2.
[Stormer, Bulk, Stringer, Furno, Surge, Breez, Nex, and Evo rush to the Tree of Harmony after defeating and cuffing Speeda Demon, Core Hunter, Voltix, Jawblade, Splitface, Thornraxx, XT4, and Toxic Reapa and stop where Twilight, Rainbow Dash, Pinkie Pie, Rarity, Applejack, Fluttershy, and Rocka are]
Evo: Whoa. This is where the Elements were created?
Stormer: Thanks to Ratchet's device, you can't be controlled. What's the story, guys.
Rocka: A villain named Black Phantom is behind all this. He engineered the entire thing. He planted the Plunder Vines to capture the princesses so he can use the Elements, plug them into himself, and drain the tree of its magic so it can't create them again.
Furno: We can't let that happen.
Rocka: You're right.
Furno: Come on! Let's go.
Surge: Yeah! Alright!
[Evo runs ahead]
Stormer: Evo wait!
[The heroes move on]
Stormer: Hit him hard, guys.
[They arrive at the location of the tree and find Black Phantom plugging himself in to the Tree]
Black Phantom: [laughs] You're too late heroes.
[Evo prepares to fire, but Stormer stops him]
Stormer: Evo, no. That could destroy it.
Furno: Guys, he's plugging himself into the Tree to transfer all its magic into him.
Twilight Sparkle: No!
Stormer: Come on!
Black Phantom: [to Arachnix] Keep them where they are.
[Arachnix multiplies and charge but the heroes fight back and Rocka gets to Black Phantom]
Black Phantom: Very clever but you're still too late.
Rocka: Look at the tree, it's wilting.
Black Phantom: Come and get me if you dare.
Rocka: Well, I guess we'll find out.
[Rocka and Black Phantom duel]
Stormer: Cut him loose, Rocka!
Evo: No wait he has to do the opposite. [to Rocka] Plug him in more!
Twilight Sparkle: That's crazy!
Evo: Just trust me. I know what I'm doing.
Stormer: Rocka, plug him in more!
[Rocka starts plugging him in]
Black Phantom: What are you doing? Recharging me in hopes of harming my mercy? [laughs]
[Rocka continues to plug him in more]
Black Phantom: Ah, it's like having a direct connection to the sun. It feels so...so... [sees the core attached to him about to blow] No. No. Noooooo!
[Black Phantom feels something touch him from behind]
Rocka: You're caught and cuffed.
[Rocka cuffs Black Phantom. Stormer approaches Twilight]
Stormer: Stabilized. All magic Black Phantom took is returning to the Tree of Harmony.
Twilight Sparkle: Great to hear, Storm.
