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.

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.

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.

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.
