Tenna is a tall anthropomorphic TV-like creature. His head is a light purple cuboid television with two antennas with rounded ends. Tenna's face is a white screen with no eyes, a long white nose, and often sports a wide grin that can have normal blocky teeth, or sharp teeth. Tenna's screen can act like a normal television screen. His nose is detachable, and some of his noses are stored in a "nose drawer." The tip of Tenna's nose can sprout a pink flower if he is overjoyed. Tenna's attire reflects his role as a director. He has a long sleeve red twin tailcoat with a set of yellow-lettered "TV" attached to the left side of his coat, and wears a yellow tie on top, a white shirt underneath his coat, a set of white gloves, a belt that has a gold TV-shaped buckle for his shiny black trousers, and long yellow shoes with black soles. Tenna is capable of shrinking his size, making himself large, or appearing squashed. This occurs based on his mood. Tenna embodies the archetypical TV host: he is energetic and enthusiastic, and always has a quick quip. Exuberant and cartoony, he makes theatrical gestures and exaggerated movements. His humor tends to be gleefully absurd, and he often drops bizarre, wacky remarks. Tenna is a natural charmer, consistently working to keep things fun and light-hearted for his audience. Tenna is behind the times. He does not know much about emails, and believes digital currency is secure. Tenna is nostalgic about the past, frequently talking about his memories. Tenna's jubilant demeanor belies a deep-seated fear of being abandoned and a desperate need for attention. He is insecure about becoming outdated enough to be thrown away or ignored. Driven by these fears, he has made at least two deals that harmed others. He convinced his ex-partner Spamton to sign a contract despite knowing it would cause serious problems. He justified this by claiming he "needed just as much as anyone else" and was convinced he could help Spamton with the trouble the deal would cause him. Tenna treats the people he works with as "expendable trash".He takes out his frustrations on his employees and controls them through restrictive contracts.
