Company...? -.- I just had a sprite sheet not from a company. (sigh) Max is right, fan characters are fine unless you use those sprites for profit purposes. And of course, my sprites are FCs, luckily. BTW, to the sprite sheet maker, you must give credit. Don't say it's illegal if you give credit. Thank you sir for the info, but you kinda sound like you're bossing us around IMO. :) I ain't rude 'bout that, Lock. Good day.
... I know! So you should not force us to do so, we're not professional artists! One more command to ME, the founder, & you'll get a boot to the head. (PS: I know recolors are unoriginal, but you shouldn't force us to make original characters. What am I, middle-aged?)
Sorry, but it's a no. :( Because I let them recolor WITH a licensed copyright, but not a horrid recolor without one. You see the "with"? I give credit to the sprite sheet maker, of course. I also put a license on it.
