A Dingo henchman who occasionally worked for Tex Hex.
Together with several other Dingoes, including Goldtooth, Barker operated a hidden Spin Factory situated just beyond Stone Canyon. There they fabricated the deadly drug called Spin, which they distributed in the Stone Canyon mining camps. Many miners became addicted and quickly lost their minds because of the drugs and had to be restrained by Marshal BraveStarr back in Fort Kerium. In this state, they were known as 'Spin-Heads'. (The Price)
According to Barker, Spin was 'just fun, it don't hurt nobody'. It is possible that Dingoes were immune to the addictive effects of the drug, much as the Dingo Llama had found a medicine to become immune against the illness caused by the Fever Flower.
- Episode 07: No Drums, No Trumpets (none speaking role) - Barker guarded the caged captive Michelle, but was taken out by BraveStarr's flying foot with a kick to the face.
- Episode 12: Big Thirty and Little Wimble - Barker was part of the Leaper Riders led by Howler. They attacked Judge J.B. and her father, then got into a skirmish with BraveStarr, Thirty/Thirty and members of the Forgotten Tribe of Prairy People. Barker was thrown off his Leaper when a Prairie Person tripped it by throwing bolo's around the creature's legs. When he tried to attack on foot, Barker was knocked down by ripple in the ground caused by BraveStarr's Strength of the Bear. Barker used an enormous bull horn to listen in on the Dingoe's enemies and learned that Thirty/Thirty was acting as Wimble's temporary father. Barker ordered him to kidnap the young Prairie Person to set a trap for BraveStarr. Barker and Goldtooth traveled to Fort Kerium where they learned that Wimble was being taken on a field trip by Miss Jenny. He sabotaged the Bus-Jet so it would go down in Howler's territory. Afterwards, he and Goldtooth decided to rob Billy-Bob in Fort Kerium, but were stopped and captured by BraveStarr and Fuzz.
