Superman: Birthright # 10 - Invasion

Metropolis is besieged by giant, monstrous-looking warships that bear Superman's logo on their face, including a giant mechanical spider. They begin killing indiscriminately. Troops empty out of the vehicles in Kryptonian garb, all bearing red capes and S-shields with their faces covered. Just as Superman is about to intervene, Luthor uses the spires of his skyscraper to project a city wide "web" of kryptonite radiation from which Superman cannot hide. When the city police start firing on the vulnerable Superman, he assumes his Clark guise and meets up with Lois, who comments on how sick he looks.

Upon returning to the newsroom, which is in chaos, Perry yells at Clark for coming to the office without a story on this crisis. Stripped of his powers and faced with imminent dismissal, Clark leaves a notice of resignation on his desk. When Lois catches him leaving, she calls him a "spineless worm" then storms off.

The "alien commander", a man dressed in armor, calls himself "Van-gar" and declares war on Earth. He proclaims that the S-shield will forever represent Krypton's rulership on Earth. Clark, his confidence restored by Lois' sermon, dons his costume and says "Like hell."
