Jongler, known as Cowboy Mike, is a key character from Deltarune's TV World. In the Light World, he is a boom mic, but his true Darkner form is a Zapper. He is one of three studio workers forced to impersonate the missing assistant, Mike, to soothe the explosive temper of their tyrannical boss, Tenna. Visually, Jongler is a tall microphone stand featuring red gloves, a grey suit, and a signature cowboy hat. His personality is a blend of anxious workplace submission and theatrical flair. He hosts a unique studio basketball and juggling minigame where players must use their actual microphone volume to manipulate gravity to score points.

In Deltarune Chapter 4, Pluey is a character and a mouse-controlled arcade minigame located inside Mike’s room in the TV Studio. Famously referred to by the studio crew as "Cat Mike", his lore reveals he is one of three microphone impersonators alongside Battat and Jongler who are forced to act as Tenna's long-lost assistant to avoid their employer's volatile wrath. In the Light World, he originates from an arcade cabinet, but by the end of the chapter, he rejects his fake persona and proudly adopts Pluey as his official canonical name. Visually, Pluey is designed as a humanoid black cat with audio microphone stands for his hands and feet, sporting a signature red bowtie and stylized pink-and-yellow tinted glasses that mirror Spamton's aesthetic and resemble the cryptic internet entity "Friend". His personality is that of an anxious, stressed-out worker desperately trying to placate Tenna; though submissive at first, he eventually rebels alongside his coworkers to claim his true independence.

Tenna, the primary antagonist of Deltarune's TV World, is the dark manifestation of the Dreemurr family’s outdated, dusty cathode-ray tube television set. Deeply traumatized by his abandonment following Toriel and Asgore's emotional divorce, he struck a dark deal with the Roaring Knight to trap the Delta Warriors inside a perpetual broadcast, ensuring he always maintains a captive audience. He is also the incredibly manipulative former business partner who directly ruined Spamton. Personality-wise, Tenna desperately hides a crippling fear of absolute obsolescence beneath a flashy, high-energy gameshow host persona. He is tyrannical, deeply insecure, and incredibly desperate for control. Visually, he is a sleek, thin humanoid figure with a light-purple CRT TV head, complete with dual antennas, a glowing screen, a sharp nose, and a wide grin. He wears a striking red twin-tailcoat, a yellow tie, white gloves, and long yellow shoes, perfectly capturing his toxic showbiz aesthetic
