||Artemus Gordon, played by Ross Martin (1)
Artemus Gordon accompanies Jim on most of his adventures, but usually operates in a support role. Clever and intelligent, Artie devises most of the specialized gear he and Jim use, as well as many tricks and traps contained within the Wanderer's lavish compartments. An expert at disguise, Artie can infiltrate enemy strongholds to support Jim (and all too often, extricate him from trouble). He is also a talented singer, musician, and fencer, but only an adequate hand-to-hand fighter and horseman.
