When SG-1 lands on Altair, they are automatically processed by the incredibly advanced machinery of the sole surviving native, Harlan, who insists they are 'better' and can never go back. They return, only to be incarcerated when it becomes clear they are not themselves but cyborg copies. Once their energy runs out, they must return, but once again Harlan insists they can't ever leave. He needs needs help to keep the underground biosphere running under a planet totally non-viable above ground. Written by KGF Vissers
Jack, Sam, Daniel and Teal'c travel to PX3-989 and they find inside a facility with machinery. Out of the blue, they are scanned by a light and faint. When they awake, they meet eleven-thousand year-old Harlan, the only survivor of a race that lived in the underground of the planet destroyed by radiation. They return to SGC and during the medical examination, Dr. Janet Fraiser realizes that they are androids. Further, their energy sources are running out and they must return to the planet to retrieve their human bodies.
"Tin Man" is an episode with funny situations and good special effects. The confrontation between Jack and the Android O'Neill is hilarious. My vote is seven.
