This is how Nightmare Nova vs Ryan goes in My Little Pony Transformers: A New Hope.
[Ryan rounds the corner and sees Nightmare Nova]
Nightmare Nova: I've been waiting for you, Ryan. We meet again at last. The circle is now complete. When I left you, I was left the learner, now I am the master.
Ryan F-Freeman: Only a master of evil, Nova.
[They start fighting then Ryan steps back]
Nightmare Nova: You're powers are weak, old man.
Ryan F-Freeman: You can't win, Nova. If you strike me down, I shall become more powerful then you can possibly imagine.
[They start fighting again]
Nightmare Nova: You should not have come back.
Ryan F-Freeman: And I think I gone on holiday.
[Ryan and Nova use their force powers but they got pushed back]
Ryan F-Freeman: Whoa. Your powers are doubled since you become who you are.
Nightmare Nova: Good. Twice the pride. Double the fall.
Ryan F-Freeman: Good.
[They fight for a bit]
Sunset Shimmer: Didn't we just leave this party?
Matau T. Monkey: You think so?
Nyx Sparkle: Probably.
Sunset Shimmer: Let's just hope the old man got the tractor beam out of comity.
[They arrive at the landing bay]
[Ryan and Nightmare Nova continued to battle
[The Heartless and Nightmare Troopers see Ryan's and Nightmare Nova's fight and head over to be ready to back her up]
Sunset Shimmer: Now's our chance, go!
[Nyx sees Ryan and Nightmare Nova's battle]
Nyx Sparkle: Ryan?
[Ryan notices Nyx then close his eyes. Nightmare Nova swings her blade then Ryan disappears]
Nyx Sparkle: No!
[The Heartless and Nightmare Troopers notice her and fire]
[Nightmare Nova then tries to search for Ryan's body, but it is nowhere to be seen]
Sunset Shimmer: Blast the door, kid!
[Nyx blasts the door controls and the door shuts just as Nightmare Nova turns to them]
Ryan F-Freeman: [voice] Run, Nyx. Run.
Sunset Shimmer: [fires her blaster] Come on!
