Then the next Touhou game, which is supposed to be a fighting game, will feature stages as inside armored sky carriers, in deep space, underwater...forget random weather effects, you're gonna get random PLANET effects.
To get back to that Batman themed question - what if Flandre Scarlet was the villain in a Batman movie?
The GCPD (Gotham City Police Department): "Well, it's hard to catch a gang boss when there isn't even an identifiable BODY in the murders. We have some survivors, but the stories they tell are not to be believed. They must have been on some pretty crazy drugs, because there's no way even a TENTH of what they claimed happened is true."
Batman: "I'll be the judge of that."
Survivor 1: "She... yes, i know. The lord of crime is a girl. Surprising, right?"
Batman: "No way. I know for a fact no human woman is capable of that kind of display."
Survivor 2 "That's the thing, Dark Knight! She's NOT human! We're telling the truth!"
Survivor 3: "She pointed at my friends, and said, and this will haunt me for the rest of my life... 'Wanna PLAY with me?'
Survivor 1: "Obviously, we'd come there for a business meeting. We weren't interested in playing with her."
Survivor 2: "We kept silent, not wishing to offend her. Some people... didn't show that restraint, and began cussing her out.
Batman: "RI-I-IGHT. Anyone got a pen? I have to record this one in my 'Fantastic Excuses' book."
Survivor 3: "We're not making this up! She pointed her left hand in their direction. 'If you won't entertain me, I'll crush your Eye...'"
Survivor 2: "Something about the way she said 'eye' made it seem like more than just this." He pointed at his eyeball.
Survivor 1: "It was. They continued to refuse. She pinched her fingers together..."
Survivor 3: "And they exploded! Literally, one second they were there, and when her fingers met, nothing left but blood everywhere!"
Survivor 2: "Seriously! The police don't believe us, but you've met people with insane powers in the past!"
Survivor 1: "You gotta believe us! We ran for it soon afterwards. We fell asleep in the alley. I woke up with a note taped to my face."
Batman: "This note? You still have it?"
Survivor 1: "Yeah." He hands it over.
Batman: "To the Dark Knight: I am astonished you would pick a name that is such a mockery of me and my kind to go around doing heroic duties under. Meet me at midnight by the warehouse where the murders took place. Believe me, Dark Knight, I will SHOW you how DARK the night can be. The Dark Knight versus the dark night. If you don't show, the next spate of mysterious murders will be in your home and in the federal prison. Yeah, I know where you live,
Bruce. Be there, or my surname will be signed all over town. In BLOOD." Flandre Scarlet. PS from Remilia Scarlet, her sis: I recommend not coming. Yes, my sister will murder your family, and the convicts, but it beats dying yourself. You don't have a hope in hell. Actually forget hell. Even Utsuho doesn't have a hope! She made me write this, giving me a sheet designed by her speechwriter, but she can't read, so I can slip in this warning. Don't come."
Choose your own ending!
Good ending.
The scene comes and Batman makes Flandre understand that what she's doing is wrong. In the middle of a battle, with him using all his gadgets and her using danmaku. (She agreed beforehand to not crush his Eye or use Lavaeteinn, because he couldn't possibly win with those, and she wants to PLAY, have a bit of a CHALLENGE.)
Bad ending.
Hopeless Boss Battle (by which i mean Batman tosses his gadgets and does almost nothing to Flandre) which culminates in him pinned down as she draws her fingers together slowly for dramatic effect while the buildings burn from the use of Lavaeteinn. "I told you, Dark Knight. Nobody mocks the darkness of the night and lives!" (She blackmailed Patchy into writing most of the lines she's spoken.)
I just realized... i just wrote another freaking fanfic while answering this!
What if Super Smash Bros. Touhou Edition? Character names, Final Smashes, B + Direction, A + Direction, Grab, Shield, Throw... give me a whole roster of moves! I understand this is going to take more than one person...
