There's a big topic floating around about this.

If I was going to do one of these, I'd put the bare minimal and use it mostly for making notes about important things that might come up later.
Whoa, thanks for pimping that for me.

OP: You don't need a lot to make a character. You don't even need a backstory or a physicval appearance. You need a reason to have the character in the story, a reason for them to give a damn and perform their role.
The sheet includes other necessary things, but its for developing the character within the story, not advertising or getting pictures (neither of which are writing the story, and make the sheet pointless).
