Omega Men #15 June, 1984.

Primus leads the Omega Men against an all-out attack against Euphorix's planetary shield. He wishes no harm to his home world, but is desperate to return to be with his wife Kalista. All of the ships under Primus' command use gravity beams to hurl meteors against a concentrated section of the shield. Unfortunately, those planet-side cannot deactivate the shield because Alonzo Dulak and Queen Kalista destroyed the controls.
