Appearance: Humanoid TV: Tenna is a tall, humanoid Darkner with an old CRT television for a head. Distinguishing facial features: He has a long, pointed nose in the middle of his TV screen, along with a mouth that often forms a wide grin. When his screen is off, these features disappear. Formal attire: Tenna wears a red suit with yellow pointed shoes, a long yellow tie, and black pants. He also wears large, cartoony white gloves. Unique rendering: Unlike most characters in Deltarune who are 2D pixel art, Tenna is rendered as a 3D model, making him stand out. Varying expressions: His appearance changes depending on his mood; he can grow and shrink with his enthusiasm, and fangs can appear when he is angry. Personality: Energetic showman: On the surface, Tenna is an enthusiastic and upbeat TV show host who loves to entertain. He is charismatic and skilled at charming an audience. Deeply insecure: Beneath his lively persona, Tenna suffers from profound insecurities and a fear of being forgotten. He is the former TV of the Dreemurr family, and after being neglected for years, he developed an obsession with having a captive audience. Egotistical and volatile: He is self-centered and prone to rapid mood swings, panicking when things don't go as planned. His desperation can cause him to act vindictively, as seen in his ruthless behavior towards the party and his former partner, Spamton. Obsessed with the past: Tenna is nostalgic and tech-illiterate, holding on to a bygone era of television entertainment. His game show is filled with references to Kris's family life before their parents' divorce and the disappearance of Dess Holiday. Ultimately kind-hearted: Despite his ruthless methods, Tenna's core motivation is a sincere desire to bring people together and make them happy through entertainment. After being defeated and shown compassion, he changes his ways and helps the Lightners.
