Q: Does the Expendable Crewman protect against a Keeper being copied by the Holographic Projector? Or being given an attaching Creeper during Creeper reassignment?

A: The Keeper being copied is in no danger from the Holographic Projector, so the Expendable Crewman’s power is not triggered. Yes, the Holographic Projector says that it’s as though the Keeper is in another player’s possession… but it’s not, really. It’s kind of like stealing… but it isn’t. The Keeper will never actually change hands or be destroyed, which are the things that trigger the Expendable Crewman.

Likewise, attaching a Creeper to a Keeper does not actually cause it to be destroyed or change ownership either, so no Crewman intervention. The Expendable Crewman’s power is not a blanket protection against EVERYTHING…

Note that Tasha Yar is the Star Trek: TNG Fluxx equivalent of the Expendable Crewman found in Star Fluxx.
