Cid's Underling (named Tom in the Dark Shadow Over Palakia prototype) is a minor, non-playable character in all versions of Final Fantasy II. He can be found in Poft, as the right hand man of Cid. The player can pay Cid's Underling for use of the airship, prior to the destruction of the city.
In the Dawn of Souls and subsequent versions, Cid's Underling can be found in the town of Machanon, feeling "lucky" that he can be Cid's underling even in "Hell".
