Burra Khan is a tiger met on Manxmouse's journey. Originally a circus performer, crippling stage fright drives Burra Khan to flee captivity, abandoning his entertainer role. This escape stems from deep anxiety, not predatory instinct, revealing vulnerability atypical for his species.

During his flight, Burra Khan encounters Manxmouse. Despite initial wariness about the potential threat, Manxmouse approaches fearlessly. This meeting forges an unexpected bond. Burra Khan's timidity contrasts with Manxmouse's inherent courage, yet mutual vulnerability builds trust. The tiger becomes a temporary traveling companion, joining Manxmouse for a segment of his journey.

Their companionship features reciprocal support. Manxmouse offers reassurance to the anxious tiger, while Burra Khan provides physical protection, using his imposing size and strength to ward off dangers during travel. This dynamic underscores Burra Khan's inherent nobility beneath his fearful nature. The tiger eventually leaves Manxmouse to seek a safer life free from human exploitation.

Burra Khan reappears at the climactic confrontation between Manxmouse and Manx Cat, present at the stadium gathering alongside other journey characters. His attendance signifies his lasting connection to Manxmouse.

In adaptations, Burra Khan's backstory as a circus escapee remains consistent. His friendship with Manxmouse receives greater emphasis than other encounters, highlighting their significant interspecies bond. The tiger's name appears as "Bula Khan" in certain dubbed versions, though his characterization stays unchanged.
