hey kingpepe long time no see.I thought about some stages for your game.One of them is the half pipe from California gamesIt would show the guy skateboarding on the half pipe while the characters fight on the ground.The music would be the California games half pipe theme.
Next up is the rooms from Dick Tracy.In the stage It would take place in 4th and B Shoe repair it would have Tracy walking back and forth and sometimes shooting his gun at the bad guys.The music is going to be the case theme.
The final stage would be World 1-4 from smb.In this stage bowser will be shooting fire in the background where you fight him (and the axe will be there too)anyways the music will be the castle theme from smb1

Well those are my ideas for the stages.Let me know what you think.

Strider, from, well, Strider - Considering him although if I fully decide he'll be in, I want to see if I can make him different from his MvC self.
Namakubi from Zombie Nation (though this may work better as a stage, the floating samurai head blowing up the city in the background) - Yeah, it'd be better to have a stage based off of the game.
Mark/Bert from Monster Party - He's also a possibility but let's just say if he does get in, Bert won't be the only monster he can transform into...
Salaryman from Takeshi's Challenge - Really tempted to put him in just for the shits and giggles.
Ninten from Mother - ...been kind of rethinking about his inclusion. There's a possibility although he might need a whole new set of sprites.
Rick from Splatterhouse NES - Maybe, need to see what kind of moveset.
One of the battletoads, from...Battletoads... - Very good chance, as for the Battletoad I might use it'll probably be Rash since he's player one in the original game
Earthworm Jim - I don't know if any actual homebrew attempts (and if there are, I'd rather not use those) but I know there's bootleg ports of both EWJ games to the NES. Although in the FCF progress thread, I already mentioned he'll be a helper for a certain character.
L Block - Tetris - Not very likely; would probably end up as a gimmicky character and...yeah I'd rather not have those.
Duck Hunt Dog - Duck Hunt - Kind of considering him since I could use someone to represent the Zapper.
Layla from the game of the same name - Really tempting, I need to see what kind of game style I can come up with her.
Noah - Bible Adventures - Eh, I think there might be a better character to use from Color Dreams/Wisdom Tree in all honesty. Also, Noah technically isn't an original game character.
Boy and Blob - A boy and his blob - I was thinking of having the Blob himself as his own character and for certain attacks, he can transform into other fighters.
Princess Tomato (Though this may work better as a stage) - Yeah, it'd be better to have a stage based off of the game as well.
Konami Man - Wai Wai World - I'll consider it, his attacks will probably consist of stuff from random Konami games.
Solid Snake - Metal Gear - Eh, not sure how he could work and he might be better as an assist for...
Bill Razer - Contra - This guy if he gets in. Although I'll have to make him less projectile-heavy,

And, I know this one would require custom sprites, but what about Captain N? He could use a Zapper and summon a gameboy for attacks, and summon obscure nintendo characters to help him out in battle. - Ehhhh, not really keen on adding characters that aren't from a game unless they're a sub-boss/secret boss of some sort, so I would say no to being an actual character on the roster.
