Major Buchanan Gravener, nicknamed "Buck," is a victim of Mysteron takeover in the instalment "Treble Cross."

The fate of the majorEdit

Involved in a car crash, Gravener is rendered clinically dead--and the Mysterons take him over in that condition. But his brain functions are not irreversibly terminated in the crash. As a direct result, he survives the situation that resulted in his takeover. Then, after his Mysteron likeness is apparently destroyed, the ORIGINAL Gravener gets instructions from the Mysterons.

The aftermathEdit

The Spectrum Organisation learns, from what happened to Gravener, that the Mysterons cannot tell their likenesses of takeover victims from the original victims if those have survived.
