Dual-Photo Cannon

We make no implication that he shot himself.

The Seacons have always been good at relentless tracking, and Seawing has a new Targetmaster mode that makes the hunt that much simpler. His dual-photo cannon form works on one level as a totally conventional (for alien war robots) way. Any metallic substance it hits is disrupted on a primordial subatomic level. The surprise is what happens to anything still solid: surviving metals glow with a powerful luminescence for hours afterward, making it nigh-impossible to hide from a second attack.
