"Our top story tonight; an explosion scientists and seismologists have determined to be equivalent to thirty kilotons of TNT has rocked the Sahara desert. That's twice the yield of the atom bomb used on Hiroshima, folks! Fortunately, no one was hurt, and there was no radiation detected…"
Kal-El, son of Jor-El, in his guise as Clark Kent, was visiting his parents in Kansas, along with Kara Zor-El, known to the world as Supergirl.
"I wanna check out that explosion," said Clark. "Finding out its cause looks like a job for Superman."
"What about me?" Kara asked. "Come on, Clark! I'm twenty-one… if I'm old enough to drink…"
"You've proven to be capable, but I need you to hold down Metropolis. This could be Luthor's doing."
Kara sighed. "Oh, alright," she said resignedly. "If it's Lex's pet project, we'll know."
Clark, now as Superman, flew off to the scene. When he arrived, he found an enormous robot that had been ripped to smithereens. Hovering over the metallic behemoth was a black haired, green eyed man in a black Kryptonian skinsuit emblazoned with the glyph of House Zar in silver. A black cape billowed in the wind, and on his hands were gauntleted gloves. The gloves, as well as the cape, were trimmed in silver.
"Well now," said the man in an unmistakably British accent, "I'd say that was quite the scrap!"
"I'll say! Are you aware that you made national news in the United States?"
"They didn't talk about how a huge robot was rampaging through Westminster, I take it. You Yanks and your fear-mongering…"
"That would explain the mess… and the explosion. Oh… Kal-El, son of Jor-El."
The man smiled as they shook hands. "Vel-Zar, son of Ken-Zar," he replied, "Known to humanity as the Black Knight. I primarily defend Britain, fighting for king and country."
"Why limit yourself to one region?" Superman asked.
"I want to defend the entire world. Humans are, as a whole, a fine species. But I can't be everywhere at once. You have a whole crew to work with."
Superman narrowed his eyes in thought. "My super-hearing detects that the Prime Minister is addressing the media about that robot. I'm willing to work out where it came from, and I'll be talking to the Justice League as well."
Vel-Zar smiled. "If you're offering to help, I'm definitely taking you up on it. Whoever sent that thing is up to no good. Hang on… it's the Prime Minister…". He glanced at what appeared to be a wrist communicator. "You bloody colonists… the Daily Planet wants to interview me! Alright…"
Vel-Zar flew off, and Superman was left with his thoughts. That wasn't a Lexcorp design, sure as Rao made little green apples. He collected a chunk of what used to be a giant killer robot and flew off to the Watchtower. His good friend Bruce Wayne would surely be able to make sense of this.
