Do you mean actually creating a character and designing their appearance or some type of ezy make character writer? For the former there are a number of graphics, computer and video game sources you could use and copy, try The Sims
or SmackDown vs. Raw
for easy, detailed examples. For the latter yes there are, I can't recall exactly what they were called but they came up in Google searches where you type in a few words or click a few options and it created a setting, story or character.
On a related note, the universal Mary Sue litmus test might be handy.
