If Simon Belmont is in Brawl, which I desperately hope he will, Brawl will become what I love most out of life (nyehehehe). To be as classic-perfect as they seem to have made sonic, he would have to be a pretty slow and heavy character, probably more than Ike. For the sake of my fanboyism, his moveset should be something like this
B: Whip - Simon violently and quickly whips straight forward or in any direction you want. You can brandish it Super Castlevania IV style to annoy or destroy projectiles! WOW!!!
Smash B: Cross Boomerang - Simon throws the infamous cross-shaped-boomerang! It travels forward, spins on place for an instant and comes back! Nuff said.
Up B: That's where I wonder most. Simon never gets the Gravity Boots, Griffin's Wing or any item that make the other belmonts able to do that super-uppercut-jump, but screw that, let him have it anyways!!! if not, it would have to be the axe...what a recovery move, especially for a heavy and slow character....
Down B: Stopwatch or Holy water. Stopwatch would be similar to jigglypuff's sing attack: the range is rather small but not as much as sing's. That's interesting but boring, I think. Let's give him Holy water!
He throws it about 6 feet away from him on the floor, and the flame does like ness's PK fire OR it travels the ground AND does like PK fire.
There is also the craplaod of items and powerups from simons quest that are interesting but.... not as much as what lived on forever in the Castlevania Franchise, don't you think?
AND I think you have all noticed that classic gaming items that are in brawl as of now are extremely fidel to their original look (just look at the fire flower!) Thus, i highly doubt that today's watch is from castlevania cuz as far as I know, and i know pretty much everything about Castlevania, the Stopwatch has 99.9999% of the time been the old kind of watch with a cover and a cord.
I think its more the one from the original Zelda or from Super Mario Bros. 2 (USA) Ok it does have the exact same effect anyways but that's it.
Of course, unless you count the VC Castlevania IV release, Simon has been making less appearances in Castlevania Games in the latest years, his last ones being a secret playable character for boss rush mode in Harmony of Dissonance and being part of the ultimate Dual Crush in Portrait of Ruin.
I'd say Richter is now easily the most popular, being a boss and playable character in Portrait, having his godly games rereleased on the PSP just last week, etc, but SIMON is pure classic goodness, he is barbarianness made sexy, and don't forget this:
Aside from the couple of years where Nintendo only had the two horrible 3D games for the 64 while the playstation got Symphony and the PC-Engine got Rondo of Blood, all the other best Castlevania games where on nintendo platforms and are all classic.
Castlevania (SIMON YAY) / Simon's Quest (SIMON YAY)/ Dracula's Curse/ Castlevania Adventure/Belmont's Revenge/Castlevania Legends/Super Castlevania IV(SIMON YAY)/Castlevania Dracula X/
Circle of the Moon/Harmony of Dissonance (SIMON YAY)/Aria of Sorrow/Dawn of Sorrow/Portrait of Ruin (SIMON YAY)/ and now the most important part of the Castlevania timeline has been announced to be the third DS game soon. there ya go, Nintendo has had almost all of them.
