Here is how Twilight, Apocalypse, Vision, Quicksilver, and Scarlet Witch confront Moon Dancer in Equestria Civil War.
(We see MD walking around Canterlot Castle)
Twilight Sparkle:(offscreen) Moon Dancer, wait!
(She turns to see her)
Twilight Sparkle: Moon Dancer, think about this for a moment! You don't have to do this!
Moon Dancer: Uh, yes I do! Because you wouldn't!
Familiar voice:(in her head) And divide Equestria into civil war?
(a blue force field appears behind her)
Moon Dancer: What the?!
(the force field disappears and inside is Apocalypse, wearing his formal tuxedo)
Apocalypse: I heard about what was happening? Logan says you're doing this because your sister was injured during the accident. Don't you know, innocent people get hurt all the time?
Twilight Sparkle: He's got a point you know. I mean, El Pablo Man did sacrifice his life for Green Arrow and Deadpool to save Starling City, and he was an innocent man.
Moon Dancer: Well let's not forget how Nur here nearly destroyed the Earth twice. And don't forget, Wade Wilson killed Slade Wilson in cold blood.
Apocalypse: You have not experienced true loss.
Twilight Sparkle: He's right. He never even met his birth parents.
Familiar voice:(off screen from above) Moon Dancer!
(they all look up)
Moon Dancer: Who's there?!
(we see Vision)
Vision: Moon Dancer! I know what you think you're doing is right. But for the collective good, you must stop this madness!
Moon Dancer: And why should I listen to a synthezoid made by a power crazy robot?
(a carriage glows scarlet and lands next to MD, nearly hitting her)
Moon Dancer: Hey!(sees it was Wanda who did it)
Scarlet Witch: I suggest you take back what you said, or next time, I won't miss.
Quicksilver:(runs up next to his sister) I suggest you listen.
(Moon Dancer then saw she was being confronted on all sides)
Moon Dancer: Nothing you say can change my mind.
(before she can leave, Wanda telekinetically moves the wagon in front of her)
Scarlet Witch: You're not going anywhere. We're going to talk, and whether you like it or not, you're going to listen.
(Seeing she had no choice, MD stayed)
Quicksilver: Stark may have created the weapon that killed the mother we knew and turned her into a soldier, but we forgave him.
Moon Dancer: That was different.
Scarlet Witch: How would you know? You've never been in a bombing attack.
Moon Dancer: And you haven't felt pain before.
Quicksilver:(punches her in anger) You don't think we know what it's like to almost lose the people you love most.(kicks her)
Apocalypse:(holds him back from further attacks)
Moon Dancer: Like I said before. Nothing you say can change my mind.
(she walks away)
Twilight Sparkle: Thanks guys, but she's right. What'll it take to change her mind.
Deadpool:(appears) Maybe some chimichangas and some tacos will work.
Quicksilver: I think you're the only superhero who likes Mexican food.
Deadpool: Trust me, Mexican food will work.
Quicksilver: Mexican food is not going to work.
Deadpool: Don't worry, Mexican food will work.
Quicksilver: Now you're just being ridiculous.
