Blue Beetle, Vol. 8 #20

The Sinestro Corps War - Fear To Live
As the Sinestro Corps War rages, Peacemaker is approached by a Sinestro ring, attracted to the scarab he has buried within him. The Reach realize that the ring is attracted to it and decide to activate Peacemaker's scarab, allowing him to become, in effect, a Sinestro ring-powered Beetle.Blue Beetle investigates and finds his friend possessed by both the scarab and the ring and is attacked by him, saved only by the arrival of the Green Lantern, Brik who, as an enemy of both the Reach and the Sinestro Corps is content to let Blue Beetle and Peacemaker kill each other. Beetle convinces her that Guy Gardner has already spoken with him and together they distract the Peacemaker long enough to allow Beetle to infiltrate his mind where, both he and the Peacemaker discover, the Beetle demonstrates its autonomy by defeating the mental version of the Peacemaker's scarab. With the Sinestro ring and the Reach's scarab defeated, Peacemaker makes the decision to physically remove the scarab from his spine, and act which wounds him terribly and may lead to his death.
