If you're just looking to spitball some ideas, make a thread in Idea Engineering.
If your character is at the point where you've got it running in MUGEN, make a thread in Projects and put some open betas out if you want critique.
Once the character's in a releasable state (i.e. hopefully not a horribly buggy punching bag) make a thread in Releases.
We the best
We will cut a frowny face in your chest, little wench
I'm unmentionably fresh, I'm a mensch, get correct
I will walk into a court while it wrecks, screaming "Yes!
I am guilty motherfuckers, I am death."
Hey, you wanna hear a good joke?
Nobody speak, nobody get choked
