Tuddrussel is a large, muscular man with stubble. He wears the standard Time Squad uniform of a black and white suit with yellow goggles.
Tuddrussel has a very rambunctious, macho, and oftentimes juvenile personality. For a man whose job involves the stability of time, Tuddrussel has shown an ironic disinterest and ignorance to the historical events he maintains. This clashes with his partner Larry's effeminate, well-mannered ways, and the two often bicker. However, he generally has a friendly disposition to people he considers friends and strives for both protection and justice. When not time-traveling, Buck likes to indulge in eating junk food, roughhousing, shooting his phasers, and playing with Otto.
Tuddrussel has a soft spot for Otto, serving as a paternal figure for him. This includes teaching him how to ride a bicycle, fishing, camping, and playing games (although Otto is often unintentionally harmed in the process). As a game, he pretends to be a superhero with Otto, and is the Future Man to the latter's Sidekick Boy.
Buck is shown to have complex developmental issues such as inflated self-image, anger control issues, and relationship problems. His intellect seems to fluctuate depending on the situation, as he has expressed scientific and historical knowledge from time to time. According to Dr. Freud, Tuddrussel suffers from an over-active super ego, which causes him to force his will on those around him. Tuddrussel's ex-wife, Sheila Sternwell, has claimed that the man is being held back by his fragile male ego, and hasn't mentally developed since early childhood.
What Tuddrussel may lack in brains he makes up for in brawn. He is incredibly strong and can pick up most heavy objects with little issue. In addition, he is very agile, and can run and jump wherever needed. Tuddrussel is knowledgeable about guns and weapons, and shows prowess in both using them and modifying them. Although he rejects many things he finds "foo-foo" and "prissy", Tuddrussel appears to be quite skilled at cooking and needlework.
- He takes every opportunity on a mission to shout out his catchphrase, "it's go time!"
- Tuddrussel is amicably divorced with his ex-wife Sheila Sternwell.
- Buck takes great pride in his Texan heritage. Although he shows a general disinterest in history, he is quite knowledgeable when it comes to the Old West's past (much to the surprise of Otto and Larry).
- According to XJ5's scan in the episode Kubla Khan't, Tuddrussel weighs 323 pounds and has an IQ of 78.

- According to Sheila in Ex Marks the Spot, Tuddrussel is used to being beat up by female historical figures due to his machismo method. For example, he's been kicked in the stomach by Mother Teresa; lost a tooth from a hit by Eleanor Roosevelt, and was assaulted by Joan of Arc. In this ep, it is also revealed that he once threw Picasso down the stair.
- It is implied that Buck and Larry share a bed in the episode Ex Marks the Spot.
- According to Larry in Ladies And Gentlemen... Monty Zuma!, Buck sleeps with a nightlight and a teddy bear named Mr. Pinky.

- Tuddrussel's country origins were inspired by series creator David Wasson, who grew up in Arkansas. Wasson almost did the voice acting for him.
- Buck was written centrally by Carlos Ramos. Both Tuddrussel and Ramos share a hatred of magicians.
