Eustace is a stubborn old man who is usually bossy to everyone around him except for his mother, Ma. Eustace has an unquenchable thirst for monetary gain. In almost every episode, he is seen sitting in his favorite red chair while reading a copy of the Nowhere newspaper and possibly watching his television which he deems is precious to him. He has an adamant disliking for Courage and frequently calls him a '"stupid dog", taking great pleasure in scaring and messing with him whenever possible, which largely stems out of jealousy that Muriel constantly pampers and dotes on Courage; however, it is not uncommon for Eustace to scare or mess with Courage just for fun or to get Courage to leave him alone. He or Muriel only appears in the beginning and end of Perfect.
Lack of talent and good looks fuel Eustace's demeanor that has been a wreck since his childhood. Throughout his life, he lived under the shadow of his mean spirited brother Horst, was hated by his mother; and neglected by his father. This is probably why he is so angry all the time. He is in constant denial over his lack of abilities and, as such, believes he can fix anything. Eustace is excruciatingly greedy, and will seize any opportunity to be paid. Courage's arrival was an unwelcome addition to his life, as it distracts his wife Muriel from feeding him; a fact that he emphasizes frequently, and paying attention to him in general. Despite this, Eustace has shown a genuine love towards Muriel (though not unbending in the least) and has on occasions allied with Courage to protect her. He is immune to emotions but has a soft spot for children that remind him of himself. His constant tormenting of Courage seems to be a guise to cover up his own cowardice, which is also quick to be displayed in a scary situation; in fact, he often displays even more cowardice than Courage himself. His favorite musician is Velvet Vick, and his interests include watching television, fishing, and reading his newspaper.
Eustace wears a pale yellow shirt with olive green overalls with black buttons, he also wears a dark brown hat and large black shoes.
Under his hat he is bald. Eustace does not appear to have any teeth.
Eustace was raised in a small household with his deceased father (who he bares a great resemblance to), mother, and his deceased older brother Horst. At the beginning of the series, he is already married to Muriel and lives with her and their dog, Courage, in the middle of Nowhere where they are constantly subjected to a series of unfortunate events.
He is referred to by Shirley, the medium, as "The Stupid One" because he never listens to her or does the right thing, which always leads to some ominous portent, such as being cursed, or having magical chaos rained down upon him.

- Eustace is only seen without his glasses in "The Chicken from Outer Space" "The Curse of Shirley" and "Le Quack Balloon". But most of the time, he never takes them off even when sleeping or taking a bath, like Muriel.
- Eustace has an old farm truck based on a Chevrolet 1½-Ton. He considers it his prize possession and the only thing he may truly unconditionally care about.
- Although Eustace is referred to as "the farmer" by many people in the show (Courage himself rarely uses his actual name), he is never shown performing any actual farm work.
- Surprisingly, Eustace actually called Courage by his name instead of the usual "stupid dog" in The Hunchback of Nowhere, Ball of Revenge, and the Cartoon Network 20th Anniversary Party bumper.
- There is a running gag where he either gets hurt, possessed, or killed at the end of the episode, then inexplicably restored to normal the following episode.
- His personality was based on John R. Dilworth's early incorrigible attitude.
- It's revealed in Bad Hair Day that the reason he calls Courage "stupid dog" is because of his mother calling him "stupid boy ".
- Although Eustace is bald in old age and was apparantly the same as a child, he had a small amount of hair in his younger adulthood, briefly seen in a flashback in "Farmer-Hunter, Farmer-Hunted."
- Eustace was unvoiced in the pilot episode "The Chicken from Outer Space", and was voiced in the first 33 episodes by Lionel G Wilson. Wilson passed away during the show's production, with the role being picked up by Arthur Anderson afterwards up to the show's end. Anderson was replaced by Shawn Wallace for the CG pilot "The Fog of Courage."
- During Anderson's time in the role, many of Eustace's catchphrases that were originally voiced by Wilson were reused as stock audio. Such phrases include "Stupid Dog!" , "Whats, huh?", and his laughs.
- He and Mr. Nasty has the same model.
- He is also named Pooh-bah by Professor Frith and Uncle Twinkletoes by Basil in Courage Meets the Mummy and Family Business.
