Ursula, a key member of the Alpha Gang, begins her journey as a primary antagonist before gradually shifting into a cooperative ally. Alongside Zander and Ed under Dr. Z’s command, she hunts dinosaur cards scattered by a time machine explosion. Her personality blends conceit and self-aggrandizement, deflecting blame onto others while clinging to an inflated sense of superiority. A running gag sees her erupting comically at any mention of “old lady”—a trigger activated even across vast distances, often by rivals Zoe or Max.

She sports long green hair twisted into spirals and a signature purple jumpsuit featuring a diamond-shaped midriff cutout. Later adaptations update her wardrobe to black pants and a sleek athletic top. Her trusted partner is Terry, a Tyrannosaurus she deploys in combat.

Orphaned young, Ursula’s rebellious streak emerged early in the orphanage before Dr. Z adopted her, recruiting her into the Alpha Gang. There, she spearheaded the Alpha Trio’s field operations. Over time, she evolves from a comedic foe to a reluctant ally, aiding in rehabilitating brainwashed dinosaurs and joining protagonists against threats like the Spectral Space Pirates.

Later arcs showcase her sporadic altruism, such as surrendering an Iguanodon card to the D-Team or battling extraterrestrial foes. Despite these shifts, she retains self-centered tendencies, rebuffing romantic overtures from Dr. Owen and Dr. Taylor. Her redemption arc culminates in alliances with former enemies against larger dangers, though her vanity and flair for dramatic irritation persist.

Media portrayals diverge: the anime amplifies her as comic relief, while video games depict a sterner, more focused strategist. Her rivalry with Zoe centers on the “old lady” quip, yet she pragmatically collaborates with the D-Team when necessary. The narrative prioritizes her gang dynamics and moral evolution over delving into her pre-adoption history.
