In the anime BEASTARS, specifically within the Final Season, Corn is a minor character who operates as an intelligence agent. He is a rat, a small herbivorous species whose physical stature belies his significant role in the larger political landscape of the series. Corn serves directly under Yahya, a horse who holds the powerful title of Beastar. This position places Corn in a supporting capacity, aiding Yahya in his mission to investigate the truth behind a surge of predation incidents that disrupt the fragile peace between carnivores and herbivores.

As a spy and information gatherer, Corn is defined by his profession. His primary motivation is his loyalty to Yahya and the cause of maintaining order. He does not appear as a frontline fighter or a central figure in the emotional drama of the main characters like Legoshi or Haru; instead, his role is functional and grounded in the world's underworld of secrets and investigations. His personality is not extensively explored, but his willingness to work in the shadows as a rat for a powerful Beastar suggests a character who is pragmatic, discreet, and skilled at navigating dangerous or sensitive situations where larger, more conspicuous animals cannot go.

Corn's key relationship is with Yahya, functioning as a trusted subordinate. Their dynamic highlights how the Beastar relies on a network of agents to extend their reach beyond what is publicly visible. In the narrative, Corn contributes to the overarching plot of the final season by assisting in the investigation of the predation cases, which is the central conflict driving the story after the characters leave school and enter adult society. He does not undergo significant personal development, remaining a consistent figure representing the intelligence-gathering arm of the Beastar. His notable ability is his effectiveness as a spy, leveraging his small size and unassuming nature as a rat to gather intelligence in a world where many animals are judged by their species and size.
