I, the Younger Brother of Superman, Obtained the Thanos Template

The entire city was instantly encased in ice, the terrifying cold nearly freezing people to death.

"Help!"

The Flash dared not stop for a moment, running back and forth, his fists annihilating the demon-like creatures.

If he stopped, once out of the Speed Force, he would be caught by the laws of physics and immediately freeze to death in the extreme cold where no life could survive.

"So cold!"

Even the robust Aquaman, Arthur, couldn't help but shiver as he looked up.

"Is it nuclear winter already?

Let me add some warmth."

Hal Jordan, also a normal human but protected by his power ring, noticed his friend's distress. Having heard about his abilities, he shaped the green energy into a giant electric heater, emitting tremendous heat to melt the snow and ice, combating the extreme cold and creating a safe haven for the Flash to catch his breath.

"David?"

Catching a metal rod plummeting like a dive-bombing plane, Clark looked up.

Diana and the others were drawn to this sky-altering attack, concerned for David's safety.

"Take this!"

A numb and icy sensation, David glanced at his arm, where volcanic heat erupted, evaporating a short section of frost.

Still numb, some of his flesh and blood cells had been frozen dead. He moved his arm and looked towards the Mantis.

Buzz!

An invisible and colorless ray pierced the sky, causing ripples in the air, as if even space-time was distorted and warped by the power of this move.

"Super gravity beam!"

Boom!

David raised his finger, and the Mantis was sent flying like it was hit by a supersonic train, a bloody hole appearing in its chest. The wound didn't look pierced but rather brutally crushed, turning flesh and bone to mush within.

Blood sprayed across the sky as the Mantis stabilized its body, clutching its painfully wounded chest, about to counterattack when another brutal strike followed swiftly, its speed like a streak of light, too fast to react.

"Your freezing ability is indeed terrifying, capable of killing me."

The coin-sized beam, powerful enough to crush bones like biscuits, rendered the Mantis's icy arm limp. Screaming in agony, David's eyes glowed with a purple light as he slowly approached, raising his hand for another attack.

"But you won't get another chance!"

Although the Mantis's cold couldn't instantly kill David, a solid hit could easily encase him in ice.

"You're weaker than I thought."

Hit again, another bloody hole filled with mush and shattered bone appeared on the Mantis's body. Severely injured, David raised an eyebrow, surprised by the effectiveness of his attack.
