Mob, Twixel, Grox, Whispy

In Minecraft, his avatar is a black skin with a red line (representing a mouth) and green eyes. ThatMob's Minecraft skin (visual representation) is a completely black silhouette with green eyes and a red line, presumably representing a mouth. Fan interpretations often turn the red line into a mask and the green eyes into glasses.
He has a calm character, a little naive, but ready to take extreme measures for the sake of people close to him.

ThatMob's Minecraft skin (visual appearance) is an all-black silhouette with green eyes and a red line, presumably representing a mouth. Fan interpretations often turn the red line into a mask, and the green eyes into glasses. The Minecraft skin is all-black, with a white smile. It's a simple, minimalist yet eerie image, especially in the context of a horror series. His eyes are white. He's energetic and expressive—where Mob is reserved and unflappable, Twixel reacts. He's the one who says what everyone's thinking, the first to voice fear. His genuine reactions are often funny—not because he's a comedian, but because they're honest. A loyal friend—he didn't have to come. Verity was Mob's problem, not Twixel's. But he showed up anyway, because his friend was being called for help. Brave but frightened—he doesn't run, but he's perfectly aware that he wants to. Fear is lived through humor and conversation; silence is worse for him.

Grox's skin is a wither skeleton in a business suit. A black skeleton with black, empty eye sockets, he wears a black jacket with two gold buttons on the sleeve, a white long-sleeved shirt, a red tie, black dress pants that match the jacket, and gray shoes. He's short but bold. The image is as simple and memorable as it gets: a skeleton businessman. The contrast between the creepy wither skeleton and the formal suit is half the joke. Arrogant and selfish, he plays with the lives of villagers like toys: he forces them to build statues for him, conducts deadly games, and collects taxes under threat of death.
Reckless – Most of the destruction and death he causes is random. He can tempt a villager to blow up a family or a pile of emeralds, causing both to explode. Gun Enthusiast – He always carries a pistol, and his weapon of choice is an AK-47 (or, in some videos, an FN FAL). He threatens anyone who gets in his way with it.
Rarely empathetic—on exceptional occasions, he shows compassion: helping a small villager defeat a bully, helping find a missing wife. But these are exceptions. His communication style is frat-bro—his catchphrases are "Aight bet!" (when things go according to plan) and "Ayo chill!" (when something goes wrong). Energetic, loud, and uses slang.
A funny villain—his criminal record is extensive, but his frat-bro personality and dark humor make him charming rather than repulsive. At the same time, he still acts as a friend.

The Whispy skin is a man with a pumpkin head. The pumpkin head is orange, with a carved-out glowing face (a classic jack-o'-lantern), and the body is dressed in regular clothes. This look is inspired by YouTubers Tuxbird and Yumi, who also have fruit heads.

His original skin, as well as fan-made variations like "JustWhispy in a Suit," can be found on NameMC and Planet Minecraft. Streams, videos, and fandom descriptions paint the following portrait:

Playful and easygoing, Whispy doesn't take himself too seriously. He jokes around on stream, laughs at his own jokes (fans love it and tease him for it), and has a relaxed demeanor.
Warm and open, he actively engages with fans, responds to fan art, and even used someone else's drawing on his stream. Fans describe him as "the cutest pumpkin boy." Creative and multifaceted, he's not just the voice of Verity but also an animator. He creates his own horror mods and Minecraft gameplay videos.
Modest but confident—he doesn't boast about his popularity, but he clearly knows his limits. For example, he explicitly asked the fandom not to use his voice for inappropriate content. He can't cook, and he openly admits it.
