Mono is a silly little cyclop Numberblock robot who has 5 blocks and has the color gray for blocks and arms, while his only eye is colored blue.
He loves playing with R080TXII, his brother who has 12 blocks but most of the times R080TXII doesn't want to play or ends badly, resulting in Mono getting upset or crying, making R080TCXX, both R080TXII and Mono's father angry at R080TXII. But sometimes they get along and can happily play again. Mono just wants to play games with everyone.

R080TXII's younger brother.
