Command Block

Command Block is the host of the competition. They're partly mechanical and carry infinite power, which will be given away as a prize to the winner of the show. If you can name it, Command Block can probably do it!

Appearance
Command Block is actually a quite bizarre command block. There are no arrows on their body like there would be on a regular command block, which means that they would be unusable as a chain command block. CB has three differently colored eyes and occasionally likes to materialize a cane that they swing around playfully.

Personality
Command Block carries a goofy personality, but they almost always know what to do in any situation, making them a respected host. They seem rather fond of their hat. Many of the competitors see Command Block as a friend along with being the host, thanks to his outgoing personality and charming cheerfulness. He seems to take everyone's interests to heart.

Trivia

 * According to "Visitor: A Pre-OSSU Special," Command Block mysteriously disappeared before the events of the episode that was meant to take place afterwards.
