Dan is the anti-hero/protagonist of the series. He is a short-tempered man with a mission to exact revenge on anyone and anything he deems has wronged him. While expressing a very shallow and abrasive demeanor, in reality, he is simply overly-sensitive to everyday pet peeves. Whether due to a psychological defect or simply personal preference, he has been noted as decidedly unable to overcome normal stress. In stark contrast to how the normal person might deal with things, he instead takes matters to extremes and sets out to forcibly undergo whatever methods necessary to achieve gratification through revenge. Taking everything personally, he believes the entire world is out to get him. Dan will stop at nothing to make sure he settles the score even if his win is pointless, even if it costs him more than he gets out of it. Dan can be selfish, as he doesn't really care what happens to others. Such as in Dan vs. Dan when he allowed the fake Dan to be arrested in his place.
