Stamina: the Postal Dude has a great amount of stamina.Marksmanship and weapon improvisation: despite never being stated to have any previous experience with firearms, the Dude is very skilled with them, as well as being able to make use of improvised weapons.His uncle Dave, a cult leader (in Postal 2) and drug dealer (in Postal 2: Paradise Lost).His corpse is located in the Paradise Cemetery (whom Postal Dude hates) who died in 1996. The Postal Dude has three known relatives When the announcer asks him if he has a real name, he replies with 'Uh, I forget. However in Postal III's introduction, the Dude says that he hates his 'f***ing name'. In the film, he is called the Postal Dude by the people of Paradise because they blamed him on going postal at the Little Germany festival and causing a massacre, when in fact Al Qaeda were largely responsible for the death toll. In the Postal games, he is called the Postal Dude because he is the representative character for the series. However, it is usually simpler to take the former route, as the pacifistic solutions often require money, which is very scarce, or the player to avoid confrontation with enemies also, if the player clears the game with a perfect pacifist run, they are awarded with an extra message in the end which says 'Thank you for playing, JESUS.' as a way to (almost mockingly) congratulate the player. However, it is interesting to note that in Postal 2, the Dude is only as violent as the player wants him to be, as the majority of the missions can be completed with or without violence. He tends to view these violent acts in a very blase fashion (like he doesn't care), or with humor/a joke ('edged weapons - someone could lose a limb! Hehe - yeah!') Despite all that, he also displays extreme sociopathic tendencies, in particular his penchant for bouts of murderous violence against anyone he comes across for a variety of reasons, and sometimes for no reason at all.

He also loves his dog Champ dearly, going to great lengths to save him on both expansions of the second game. He is a very easygoing and imperturbable guy, usually not minding the stuff happening around him and constantly making unflattering and sarcastic remarks about them. In Postal 2, PD is shown as an antisocial and reclusive loner who is just minding his own business.

There are hints of at least one mental disease as shown via his diary and War Journal (in the manual, or on Hard or Nightmare mode in Postal Redux), suggesting that could be one of the reasons for his violent and destructive actions. In the original game, the Postal Dude has very little in the way of personality, being shown just as a malevolent and manipulative psychopath who hates everyone and everything. This is verifiable by the fact that within the game files, Hunter's voice clips are labeled as 'demon' and that when taking damage, the Postal Dude's various screams are provided by Vince Desi. Compared to in that game, in Postal, the voice heard in gameplay played by Rick Hunter isn't the Postal Dude himself, it was intended for it to be another voice, possibly of supernatural origin, in his head commenting on his killing spree. In the Postal 2 beta shown at E3 2002, the Postal Dude had no glasses, exposing his reddish eyes, and he was much taller and thin. Despite never being stated to have any previous experience with firearms, the Dude is very skilled with them, as well as being able to make use of improvised weapons. He is always seen wearing sunglasses and a long trench coat whose color varies between games, as well as a t-shirt with a stamp of an alien.

Postal Dude is depicted as a middle-aged tall, thin man sporting a soul patch.
