Usarapa, alias Ursula, emerges as the central antagonist in the first season and reappears in later story arcs. Commanding the Alpha Trio within Dr. Z’s Alpha Gang, she spearheads efforts to collect dinosaur cards critical to the group’s quest for global dominance. Abandoned in an orphanage before her adoption by Dr. Z, her formative years as a delinquent forged her cunning, egocentric demeanor.

Her striking appearance features long green hair, piercing light yellow-golden eyes, and a bold wardrobe: a snug dark-red pink dress, pink high heels, and coordinating hand-warmers. Interactions with allies and rivals alike showcase her vanity and penchant for delusional self-aggrandizement, frequently deflecting blame for mission mishaps onto subordinates Zander and Ed. A running gag underscores her explosive reaction to Zoe Drake’s taunts labeling her an “old lady”—a jibe she inexplicably detects even at a distance.

As the series progresses, her role shifts from outright villainy to uneasy collaboration. During the second season, the Alpha Gang temporarily allies with the D-Team against the Spectral Space Pirates, though her actions remain driven by loyalty to Dr. Z and personal survival instincts. Dr. Owen’s persistent romantic advances toward her meet repeated rejection, culminating in her blunt dismissal of his marriage proposal.

Leading the Alpha Trio, she directs a Tyrannosaurus called Terry, though her strategies often hinge on Zander’s error-prone schemes and Ed’s bumbling antics. Brief glimpses of cooperation surface when confronting shared foes like the Spectral Space Pirates, yet her arrogance and sense of entitlement persist unaltered.

Her documented appearances remain confined to the main series, with no expanded role in supplementary media. Character consistency prevails across the anime’s two seasons, maintaining established traits, relationships, and backstory without deviation.
