Evil Bug

The Bug is an unrecoverable error made by The Creator while he was creating a game. It is also the boss for the single-player Campaign mission, ??? (Campaign Level).

Appearance
It is all black, but has red borders all around itself. It has three heads, one big (middle), one medium (left), and one small (right). The big head has one eye on the right side. It also has some kind of mouth. The medium head has two eyes, and a few teeth. The small one is just a miniature version of the medium sized head. It has a giant glowing red thing in the middle of his chest. His arms seems to be limp, because he is dragging them. He then has short stubby legs.

Story
This monster turned everything cubical and ruined Newbie's world. Newbie finds The Creator who asks him to find and destroy The Bug. Newbie then gets into the game using a "Blockeye" ("Blockulus" on iOS devices) and defeats the monster. At the end of the fight, The Bug turns Newbie into a bug and exiles him in the internet
