A blank synthetic humanoid body built on Coppelius by Altan Inigo Soong to receive a human consciousness, which became the new body of Jean-Luc Picard after his death in 2399.
The golem is the product of work by Bruce Maddox and Altan Soong, son of Data's creator. It is an android body with no mind of its own, made so that a living person's consciousness could be moved into it. Soong meant it for himself.
It is introduced in the Picard two-parter Et in Arcadia Ego. Picard, terminally ill with a brain abnormality, dies on Coppelius after persuading Soji not to summon the synthetic alliance. Soong, Agnes Jurati and Soji transfer his mind into the golem.
The new body is built to look and feel like the old one. It has no extra strength and will age and die at about the time Picard might naturally have done, but it is free of the disease. He lives in it for the remainder of the series.
