Alses,... I still want to hear your idea... but it's OK if you don't want to post it.
Sexy D / + / B certainly sounds interesting, but... was that the way they worked in game? (I never used Telekinesis pins...) What if they were recovering and they got trapped under the stage, or even worse,... in FD's lip?
Maybe we could expand on Earthshaker like this:
You could mash the B button and the faster you mash, the faster it comes out. Or it could always come out late-ish but the power could vary the more you mashed. Or I could save your fingers the trouble and make a new one.
We could always bring Flame Blast back from the dead?
The ideas we have so far are:
Sexy D / + / B (by Humble)
Earthshaker (by Mr. Weegee)
...Flame Blast? (by myself)
We need more ideas! (Not that I don't like the current ideas or anything like that.)
According to the TWEWY resource he provided, that is exactly how they worked in game. Since it pulls towards you (assuming you are on the stage) they are being pulled upwards, and a moment later they could simply DI towards the lip of the stage, then jump or up-B to grab the ledge. If you time it well enough that you disrupt their up-B and recovery entirely, then it took skill and timing and should be a good way to gimp someone. The wind shouldn't cover the entire stage, and because it always pulls towards you, if you try to gimp them away from the stage you have to be farther away yourself, and if you try to pull them under the stage they simply DI back out and then go up. Really, it isn't overpowered, it uses the same mechanics as the game, fills a slot in the moveset, and should be useful to Neku.
Earthshaker sounds interesting, but is also probably more over powered then Sexy, and what will it do if you are in the air? Sexy works fine in the air, but earthshaker needs to be standing on the ground to work; and if you tried to make it none broken by making it slow, then it would be telegraphed in advance and never land against a good opponent; if you made it fast so they couldn't easily dodge, then it is over powered. All in all, it isn't going to be as balanced, or effective, as Sexy would be.
Flame blast just doesn't sound as original, I mean he already has d-tilt for psychokinesis- Down-B should be more unique then that.
His Down-B could be changed to Frantic, where he generates a tornado (using wind effects) which would pull enemies in, and then put them in hitstun without generating damage, and toss them out the top of the tornado (Frantic immobolizes the opponent, the hitstun is similar to that, and it generates a tornado like this would) Its good because it wouldn't be overpowered at stopping recoveries, it wouldn't be overpowered on stage, it deals no damage, and serves as a good set-up to some cool things Neku could do (for example he could use Down-B, then jump and fire the Nexus Ray right where he knows they will be spit out)
I also think a section that you are missing, throws, should be commented upon.
