Battat takes his job as an impersonator very seriously, acting out the most elaborate portrayal of Mike and expressing annoyance with his fellow impersonators for not acting the part. As Mike, he talks constantly, claims to be Tenna's most trusted friend and helper. Out of costume, he is often theorizing about the oddities of the world when he's alone. Costume appearance: An anthropomorphic Darkner with no eyes and a large smile. He has a microphone for a head with a combover. He wears a suit with a red bow tie and white gloves, and holds a microphone in his right hand. Noncostume appearance: A small humanoid Pippins. He has a white, hexagonal head with a pair of eyes with green pupils. He typically wears a green suit/poncho combination. Speech Pattern: The following are dialogue examples of how Battat speaks. "We are live, we are on air, we are recording, YOU are background noise! Get out!" "So who is Mike!? Who is he!?!! Is he just Tenna's imaginary friend!?! Is he Tenna's alter-ego!? Like some alternate personality or something?! And why the hell does he get so much love and attention!?!" "AGHHH, I give up!!! As long as someone's Mike, it'll work out!"

Jongler is more relaxed than Battat in their job of being an impersonator, not knowing how to act like Mike and forgetting their lines when they are confronted. They consider themselves the "muscle" of the Mikes and are laconic about their role, wondering why they cannot say whatever they want while in their own Mike persona and whether impersonating Mike for so long means the trio is Mike when acting as him. If Tenna is no longer present, they conclude that the three of them can keep being Mike for as long as they want. Costume appearance: A large anthropomorphic microphone with a long, rectangular microphone for a head, boxing gloves on their hands, and a cowboy hat. Noncostume appearance: A tall Darkner that resembles a television remote control. They have a long, navy blue head with a red light on the top. They do not have any facial features, though they can still blush. They wear a navy blue suit that has six triangular buttons in the middle of it, three red, three white. They have white shoulder pads and red gloves. They seem to only have one leg. Speech Pattern: The following are dialogue examples of how Jongler speaks. "Nice to meet ya. It's me. Big mouth Mike. Dey calls me dat, 'cause I don'ts shaddup, see? Dis is a private room. We got private uh, eyes. We been... investigatin' you. We, uh... We like what we see. Keep it up." "What if when we pretend to be Mike, we's actually Mike?" "Does dat mean I can finally say whatever lines I wanna say?"

Pluey does not speak in words. He's mostly silent, but like all the other Shadowguys, his voice is just a saxophone. He is described as the Mike "who listens". Pluey remains generally upbeat, only frowning after considerable scolding from Battat. He seems to be very invested in his cat-like role, as he wears his costume even when it is not necessary and even plays with yarn. He is a fan of jazz music. Whenever out of costume, he instead puts on a cat ear headband to substitute. Costume appearance: A black-and-white cat with a white outline, giving him a shadow-like appearance. He has yellow and pink eyes, microphones instead of hands and feet, as well as a tail with a small mouth on the end. He wears a red bow tie on his neck. Noncostume appearance: An entirely black silhouette of a broad-shouldered human mobster in a fedora and trenchcoat, with a white outline and mouth but no visible eyes.

Tenna, full name Ant 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. He is oblivious to the fact that "Mike" is 4 different costumed people pretending to be the real one, at one point commenting that "the size of Mike's ass is very variable lately". He thinks that they are all the same Mike. Appearance: A tall anthropomorphic TV-like Darkner. His head is a light purple/lilac 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. 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.
