Dino Tricera stands among the Core Dino Knights, prehistoric creatures empowered by Earth to repel the Dragozaur alien threat. His base form is the mighty Triceratops, and he fights alongside his teammates from their base, the Dinotarium. Within the team, Dino Tricera exhibits fierce combat enthusiasm, attacking Dragozaur forces with aggression rivaling his comrade Dino Stego; this relentless drive shapes his vital role in the group.

Originally armed with the Jade Tricera Spears, Dino Tricera's power escalates dramatically after a pivotal battle against the Dragozaur wizard Dark Dragon. This confrontation results in the demise of both Dino Tricera and their leader, Dino Tyranno. Salvation arrives through the legendary Dino Knight Dino Ramph, who expends his own energy to resurrect them. Reborn as Ultimate Dino Knights, they gain immense new strength. In this ascended state, Dino Tricera wields the formidable Triple-Threat Halberd and unleashes the devastating "Lightning Bolt Strike" technique, marking a transformative leap in his abilities and battlefield contribution.

His history includes clashes with the Drago Clones, shadow warriors crafted by Dragozaur leader Diamond Ryugu as dark reflections of the Core Dino Knights. Among these clones, Drago Tricera emerges as his personal nemesis, adding a layer of complexity to his ongoing struggle against the Dragozaur forces.

His documented actions and evolution are chronicled within the narrative of the 26-episode television series.
