Trivia is a purple-furred hedgehog with red streaks in her gravity-defying quills. Her muzzle, arms, the inside of her ears, and chest are beige. Trivia's eyes are scarlet-red, the same shade of red as her quills. The only visual difference between Trivia and Hecate is Trivia's attire. She wears a white t-shirt and leggings, a large, black-hooded cloak, and white shoes with a black cross on the front. The soles are also the same shade of black.
Trivia's personality is the opposite of Hecate's. While Hecate is calm, quirky, and positive, Trivia is spiteful, abrasive, and has temper issues. Though, she is calm most of the time, she does break easily. Trivia isn't very social but she does have respect for some. Trivia is loyal to her boss, Varusa D'Era, claiming that she would never betray him, though, this trust was broken when she decided to stay with Finitevus.
Trivia appears in Sonic Universe Fanfiction Story 1: Dr. Finitevus, Post Genesis Wave along with Ashton the Sparrow.
