Dan is the the titular villain protagonist in the animated series, Dan Vs.. He is a vile, ruthless, argumentative, vengeful, and devilish man who always calls his best friend Chris whenever he is plotting or enacting revenge. He has said that he has been thrown out of libraries and jailed on multiple occasions. Dan has said to have been tear-gassed so many times that he no longer feels any effects from it, and he has also been maced enough times to claim that it is "tangier" than tear-gas. He seems to really like his car, despite it's state of disrepair; several of his "revenge missions" were instigated by people damaging or tampering with it. He also is very fond of his female cat, Mr. Mumbles, and cannot remain angry at her for very long (she is the only creature that cannot get Dan angry). At the end of every episode's prologue, he always raises on fists in the air in anger and shout out the name of whatever he is about to go up against and add the word(s) to the episodes' titles (he doesn't shout at the end of the intro of Dan Vs. The Gym however). While Dan is more so of a villain, he has a more gentle side.
His everyday outfit consists of blue jeans, black boots, and a black T-shirt that says "JERK" in white letters. He has black hair, green eyes, a goatee, a slight stubble on his chin, and round, rotten teeth.
Dan is a rude, crude, mean, nasty, vile, greedy, uncouth, sadistic, unpleasant, cantankerous, impatient, prickly, surly, grouchy, churlish, obnoxious, quarrelsome, judgmental, truculent, selfish, ill-tempered, angry, furious, impolite, appalling, objectionable, hotheaded, indecent, caustic, insulting, repugnant, detestable, ignorant, and offensive man. He seems to care about no one but himself. He mocks his best friend Chris for being slow-witted and very incompetent, and dislikes his wife Elise even more than he hates Chris. He is definitely prone to yelling at people, and threatening them by getting revenge. However he seems to love his teddy bear Brutus, his pet kitten, Mr. Mumbles and his red car. Whenever his car is destroyed and/or vandalized, he will storm right out of his apartment and track down the cause of his car's destruction and/or vandalism. He is also very disrespectful to children, which implies that he hates babies in general, according to his "revenge list". Overall, Dan is a complete jerk as his shirt implies.

"The Wolfman" - Kidnapped a trick-or-treater and chased another along with Chris presuming it to be the real Wolfman, but are arrested for chasing the child. Despite this, they leave the police station and continue to hunt down the Wolfman. However before Dan shoots the Wolfman in the buttocks with a bow and arrow, he takes it from a haunted yard that has been graverobbed by the two.
"The Animal Shelter" - Gave Chris a threatening message, poisoned him with meat loaf, stole his and Elise's car, and blew up an animal shelter. Although his heroic side is when he rescued his kitten, Mr. Mumbles and all of the other animals.

This isn't the movies - THIS IS REAL LIFE! STOP LIVING IN A FANTASY WORLD! THE WOLFMAN SCRATCHED MY CAR, AND HE MUST PAY! NEXT MONTH!
~ Dan yelling at Chris about the Wolfman scratching his car.
How DARE YOU LET YOUR MACHINE PICK UP! You are scum! You are worthless, spineless, and rotten to the corpse! That's it! We are no longer friends - I hate you! We are DONE. If you ever try to speak to me again, I WILL LITERALLY STRANGLE YOU!
~ Dan threatening and insulting Chris for not picking up his phone.
Revenge is a dish best served immediately.
~ Dan claiming revenge.
Dan flipping out after he hears that brass knuckles were confiscated.
In "Elise's Parents", Dan tells Elise that he has no dental records. A possible nod to The Dentist in which he stole his own records to prove that his dentist was a supervillain.
In the episode "Dan*", it is shown that Dan is 5"6" in height, weighs 105 lbs, and was born on October 31, 1975.
Chris is rumored to be his only friend. Despite this, he has a friend named Ted, who is on Dan's list and has yet to appear in the series.
As mentioned in "Dan*", He also has a football table, but he claims he is an "air hockey man".
He is voiced by Curtis Armstrong who is known for the role of Dudley "Booger" Dawson from Revenge of the Nerds and playing Snot in American Dad. Armstrong also appeared as Metatron on Supernatural.
Dan has many characteristics similar to that of Yzma, the villain of the Walt Disney Pictures feature film titled The Emperor's New Groove; both are loud, both mistreat their right-hand men due to their incompetence and stupidity, and both also force their minions to do things that are evil. They also share the point of being maniacal and psychopathic.
In a short promo for both series, the My Little Pony: Friendship is Magic, character Pinkie Pie painted Dan's car pink for absolutely no reason, causing him to shout her name in anger. It is not explained how or why she painted his car or ended up in his universe.
