Gaius is a character who was created by an author's apparent failure to realize that 'smart board' should be written as 'SMART board', thus creating a sentient piece of cardboard who prefers to be known as Gaius, after Gaius Suetonius Tranquillus. Gaius sounds like an elderly English man, and having been born in the NCIS: Los Angeles continuum, he has a full knowledge of that world and everyone in it. Because of his lack of a body, he cannot be an agent, but he has agreed to serve as an adviser to Agents Grace Leon and Ally Malet for the time being, and may join them in future missions and MSTs. As such, he is loosely affiliated (though not actually part of) the Floaters. He is written by Astral Void.
