I've been having a fan-made Mortal Kombat/Injustice story mode idea in my brain and I thought "Why not try texting out about a crossover multiverse story?" Also, after I watched this fan-made MoxxieVerse video on YouTube (https://www.youtube.com/watch?v=V3iHE_GThWs), that's when I thought of a semifinal chapter involving the Evil Moxxie. I'll explain a little more to you.

CHAPTER 09: Arcane Wings
Primary Fighter: Autistic Octavia
Support Fighter (similar to kameo fighter): Aphasia Loona

Opponents:
1: Dark Striker (w/Dark Pentious)
2: Dark Stolas (w/Dark Green Arrow)
3: Dark Octavia (w/Dark Spike (MLP Make Your Mark))
4: Dark Blitzo (w/Dark Loona)

Dialogues:

Before first fight:
(Many versions of Octavia and Loona, along with their allies, including a deer dude named Kyle (WatershipFamily98) and a dragon dude named Orion (PhoenixAegis), accompanied by the whippet hellhound lady named Belladonna, are on a meeting about the multiverse invasion info.)
QUEEN LOONA: No way... That explains why "Evil" Moxxie was invading many universes.
STEWARDESS LOONA: Even my world's Millie was missing.
STEWARDESS OCTAVIA: I'm glad BatMan called us for this latest info.
AUTISTIC OCTAVIA: I'm with you, Via. We'll provide as many help as we can. (Aphasia Loona nodded yes with her.)
LOONIEVERSE OCTAVIA: Same here. To be honest, I wish for the bad luck to happen to us. Now, I'm not sure it may happen.
STEWARDESS LOONA: Princess, as we speak, Young Bee is already searching for this Moxxie and his other minions and collect his powerful artifact. I'll bring in the rest of my champions to support you guys.
QUEEN LOONA: I'll do so as well. We cannot allow this invasion to happen any further.
KYLE: Count me in, ladies. I ain't gonna let this Moxxie mess with you guys like that.
ORION: Same here. My chunky army will help out end this nightmare in the name of justice.
AUTISTIC OCTAVIA: (Pointing the direction away from them.) Um... guys?
(About eight of the dark versions arrived and charges to attack the demon gals and their allies, including a deer dude named Kyle. Meanwhile, Autistic Via and Aphasia Loona fought Striker and Pentious away from them.)
AUTISTIC OCTAVIA: Let's take care of these guys first. (Aphasia Loona nodded yes.)

Battle 1:
Round Won: AUTISTIC OCTAVIA: You're just as bad as my world's Striker!
Round Lost: DARK STRIKER: (Chuckles evilly) Not so majestic now, are you, Princess?
End of Battle: AUTISTIC OCTAVIA: (Cuddles to herself) Thank you, Dad.

Before 2nd battle:
(Dark Stolas and Arrow knocks out some allies before heading towards the mentally disabled demons.)
AUTISTIC OCTAVIA: Come on. We've gotta help the others.

Battle 2:
Round Won: AUTISTIC OCTAVIA: There is no doubt I'd prefer my Stolas to you, old man.
Round Lost: DARK STOLAS: (Chuckles) Fool. My arcane magic is more powerful than yours.
End of Battle: AUTISTIC OCTAVIA: We're coming, guys!

(She then ran to use her arcane magic to heal their allies and ran to help Kyle up to do so as well.)
AUTISTIC OCTAVIA: Hold still, Kyle.
KYLE: Thank you, your Highness.
(Via then saw her dark version, along with Dark Spike, who just knocked out Stewardess Loona, LoonieVerse Via, Steward Orion and OrionVerse Belladonna before walking to fight her.)
DARK OCTAVIA: Once Moxxie and we are finished with all of you, the multiverse shall be his. Nothing you can do to ever stop him, this time.
AUTISTIC OCTAVIA: My dad warned me about such a dark mirror like yourself. I do not fear the likes of you.

Battle 3:
Round Won: DARK OCTAVIA: Enough! It is time I show you what I'm truly capable of.
Round Lost: AUTISTIC OCTAVIA: Man, you're as tough. I'll give you that.
End of Battle: AUTISTIC OCTAVIA: Let's end this fight, Loona. (She nodded yes... again.)

Before 4th battle:
(They then walked to help the other knocked out demon gals, Orion and Belladonna back up again before they heard the machine gun shooting. Autistic Via summons the barrier to deflect the bullets shot by Dark Blitzo, accompanied by Dark Loona.)
AUTISTIC OCTAVIA: We'll handle the remainder. You guys detain the rest.
STEWARDESS LOONA: Will do.
ORION: Go get them, ladies.
(Kyle then walks to them and gently touches Aphasia Loona's arm.)
KYLE: If there's one demon lady I wouldn't doubt at all, it's you, Loona. (She then gently touches his arm as well with a romantic smile before the duo faces the last of the two dark versions.)

Battle 4:
Round Won: DARK BLITZO: (Chuckles evilly) MORE!
Round Lost: DARK LOONA: Let's finish them, old man!
End of Battle: AUTISTIC OCTAVIA: I think that's all of them.

End of chapter:
(Later on, after they successfully detain them, Autistic Octavia has got a phone call from Young Bee and answers it.)
AUTISTIC OCTAVIA: Highness, anything okay?
YOUNG BEE (Off-screen): Yes, I got the book, but Moxxie and the others are after me.
AUTISTIC OCTAVIA: Lure them to some abandoned factory. We're bringing the reinforcements.
YOUNG BEE (Off-screen): Will do, but, please, hurry.
(After she hangs up, they all nodded in agreement with each other.)

Just let me know about what you guys think about my ideas, even though it's a fan one, okay? Thanks.
