Blume serves as a core member of the Sand Rats, a bandit group active on the planet Zola. Working under Rag's leadership alongside Dyke and Chill, Blume participates in the group's discovery of Jiron Amos starving in the desert and their subsequent assistance in stealing the Walker Machine Xabungle from the trader Carrying Cargo.

Blume possesses a sarcastic and sharp-tongued personality, frequently delivering witty remarks and exhibiting a smart-ass attitude. This trait surfaces during the Sand Rats' adventures, often in reaction to Jiron's impulsive actions or the chaotic situations involving the Iron Gear land ship. Blume presents a slightly feminine appearance.

Within the Sand Rats, Blume operates primarily as Rag's subordinate, engaging in group activities that include mechanical operations and confrontations with antagonists like Timp Sharon and Horla. Interactions occur with other members, such as the young Chill.

Blume also appears in the compilation film *Xabungle Graffiti*, which condenses the television series events. The character maintains consistent personality traits and role without new backstory or development across both the television series and film. Blume remains a stable supporting presence within the ensemble, contributing to comedic moments and group cohesion without individual narrative arcs. The character does not appear in other official media. Background prior to joining the Sand Rats, family history, and motivations beyond group loyalty remain unexplored.
