Pa Nguyen was an overweight Vietnamese man. He had thinning grey hair, and wore a red shirt that had white sleeve cuffs and a blue collar with three blue stripes on each sleeve, and it read "Go Team" in white letters. He also wore blue jeans and grey sneakers.
He is first seen as a corpse in his debut. His skin is a pale yellow-grey, he has wrinkles under his eyes and lines around his mouth, and he had crude drawings on his face courtesy of his son’s, including a penis, a mustache, and the words "Jeter sucks!".
In The BoJack Horseman Show, we see him for the first time alive in 2007. He was shown to have had yellow-ish skin, and he has slightly less wrinkles from the time of his death.
His first speaking role in a flashback to Diane's teen years in the 90s shows him with thinning, shaggy dark brown hair, and had a normal skin tone. He wore a green t-shirt with white trim that read "Boston Athletics" in white letters on the front, and dark blue jeans.
Pa Nguyen was a Vietnamese man, the verbally abusive father of Diane Nguyen and the head of the Nguyen family. In his daughter Diane's words he was a "mean, sadistic alcoholic who never supported anything [she] did and actively delighted on seeing [her] fail."
Nobody in his family seemed particularly grieved by his loss and just wanted his body out of the family home.
He died in his sleep in 2014. His sons made the discovery after playing a prank of doodling his face before they realized he was dead. As a result, his body is left to rot for hours.
Diane organizes what turns out to be a pointless funeral as her mother and brothers had his body chummed to be thrown at Derek Jeter (much to Diane's shock and horror) who was Pa's alleged rival though it is doubtful Derek Jeter was aware of Pa's existence (therefore, an entirely one-sided rivalry).
In his chummed state he rolls towards Derek Jeter who is aiding an old lady cross the street practically knocking them over. The container is then lost somewhere in Boston.
- Like his wife, his real first name are never revealed.
- He and his wife are similar to Butterscotch and Beatrice Horseman in that they are verbally abusive toward their children.
- There is a flashback in a previous episode where he is shown alive.
- Despite the abuse he gave Diane, she lied to BoJack to get him to open up while writing their book, she claimed she sat on the roof and look at the stars with her father.
