Newbie is the main protagonist of the Campaign story. He is also the player character.
Newbie starts out sleeping in San Blocksisco on his farm when suddenly an outbreak of zombies and monstrous creatures started to infect most of the city's citizens.
He fights through hordes of various creatures, eventually getting to the source of the outbreak in School, which teleports him into the Block World. Where he meets a schoolgirl whom will help him to solve and finish the outbreak by reaching the Parallel World. It is in the Parallel World where he meets (and fought) the Dragon to discover of what caused the outbreak.
He then journeys with the schoolgirl to the Crossed Worlds, where he finds The Creator and fights the bug that ruined his world. He eventually succeeds, but out of anger, The Bug turns him into a bug himself and found himself on the Internet.
Newbie is a middle-aged man with brown hair, a brown beard, a red shirt, navy blue pants, and has a brown holster for his gun on the side. He is sometimes seen with a red headband with a pixel of hair covering it. He had a nose and a green shirt in older versions.
All Campaign levels.
- The Newbie skin seems to be derived from the popular "Griefer" skin created by gab51299 of Planet Minecraft.
- Newbie somewhat resembles Steve, the main character from the indie video game "Minecraft" by Mojang, having similar pants, short-sleeved shirt, hairstyle, and beard.
- In the iTunes description, Newbie is called "Pixel Man".
- He is the default skin of the player and in the older version of Pixel Gun 3D (like stated above), he was very similar to Steve. In the new version, he wears a red shirt, wears shades, and slightly resembles Duke Nukem.
- There is a portrait of the Newbie in the living room in Farm.
- Even though the Newbie's actual skin includes a pair of shades, in the comics he cannot be seen wearing shades.
- In 10.0.0, he no longer has shades in his skin and has a headband, just like in the story comics.
- The portrait of the Newbie in the farm level looks like the older version of him with green clothes and no shades.
- After the Bridge level is completed and Newbie has jumped off the bridge, while he is swimming, he refers to himself as "hero".
- His appearance changed in the comics as the 12.2.0 update arrived.
