Bull Huxter first appears in The Blue Djinn of Babylon. He is a Human, and apparently one of the few non-related people who knew of John and Philippa's true identities as djinn. He was an old friend of Edward Gaunt and came over to play a three way djinnverso game versus Mr. Gaunt and Philippa. Interestingly, this is one of the first times Mr. Gaunt is seen interacting with non-family members of the djinn world. Later, Layla mentions that he disappears along with the canister containing Iblis that was headed to Venus: this being because he had perpetrated a con to get some extra money. He is also (in Iblis' opinion,) frustratingly deaf, due to being around too many rocket launches.
