Mono is a Cyclops who appears in The Mighty Fall. He was voted champion of the cyclops, and as such takes place in the Kyzaj Tournament on Yu'biusk in an attempt to become leader of the Bandosians. His manner of speech is highly simplified, with all of his dialogue being made up of one word responses.
He fights against Lol in the first round of the competition, but he loses and is killed.
- His name comes from the Greek prefix 'mono-', which means one.
