Well, ever since the introduction of ship and station explosions, you may have noticed wrecks explode violently sometimes, though not as violently as the initial death.
Well, if a gaian happens to come along and shoot, say a phobo's wreck, the wreck's explosion may actually end up killing the gaian processor if it has already sustained enough damage.
