Suppose I could write a few lines.
What does your character like to be called? (title, full name, nick-name)
Grit, Grittlebone. Only his siblings know his real name, although they rarely use it.
Type of humor? (Childish, sarcastic, no humor at all and so on)
Dry, sarcastic, cruel at times.
If another person is bugging your char, how will he/she react?
Depends on what they're doing. Ignoring them or walking away usually works, though he'd have no problem fighting them if they insisted on it.
The most negative side of your character? (Moody, petty, stupid ect)
Selfish and a hopeless gambler, especially while drunk.
The most positive side?
Willing to forget about old disputes if there's money or other advantages to be made (wait, is this a good thing..?).
