First the Sword wielding phantom titan. having just sliced open a land raider like a can of soup it braces to send another poor victim into oblivion.
And second a Phantom getting rather tired of the pointy's attempts at air superiority, it decides to release a micro-singularity into the beak of the flying pest, and scatter its remains with a healthy dose of missiles. Give a hunk of steel wings and a dragon head, it still is just as predictable as a hunk of pointy steel flying through the air. Even space marine targeting computers could plot that firing solution.
Any clients want me to splatter a few silly space marines.. Im almost always game.
