.. and who can ever forget those cursed nights...
WHAT A HORRIBLE NIGHT TO HAVE A CURSE
Heheheh...bad joke, sorry.
Anyway, if Simon is included, I think they will use these songs from the games:
Vampire Killer (obvious, really really obvious)
Bloody Tears (also obvious)
Theme of Simon (ok Simon goes NOWHERE without his theme)
Wicked Child
Heart of Fire
Cross Your Heart (aka Crucifix Held Close in PoR)
And um...I can't remember anymore, but these are all themes that debuted in games that had Simon as the hero. They might use other "non-Simon" themes though.
As for Simon's moveset, I think they should make him into another unique character. Like, he can use his R to grab onto platforms with his whip and swing with his legs extended. It wouldn't hurt much but would have a good knockback. I know everybody has done a moveset but I'd like to do his four specials one more time:
B: Knife Throw: Throws three knives (like Richter). Fast, but very weak (think Fox's Blaster).
Side-B: Cross: Throws a blue cross and it goes a distance before coming back to Simon. Good damage. If thrown from a certain distance it can do massive damage on its return trip.
Down-B: Holy Water: Throws a vial of blue Holy Water on to the ground and it generates blue flames. Very damaging if enemies are trapped in it.
Up-B: Now this one, I tried to add to it a bit of innovation, but I don't know if they can do it. Anyway, here goes. On the ground, Simon throws an axe at a set arc. In the air, Simon does a Super Jump with a flaming fist. The axe does OK damage. The Super Jump goes a very great distance, but does mediocre damage.
Also one thing about Castlevania item(s): I would like it if they could include two Castlevania items. One of them would be the power-up item and would power-up normal (non-special) attacks. The other would simply be, a big heart. Getting one of these allows an Item Crash for your character! This means that your special move will become a bit better/stronger and flashier, but not to the scale of a Final Smash. I think the heart one would not work though, even if they already have Simon in the game.
So what do you think of this Castlevania fanatic's creativity, huh?
