"You fools thought you could handle a being of my caliber," Darkseid loomed over the fallen bodies of the heroes that were sent to challenge him, his red eyes shining ominously. "But you all forget that I am a god. Darkseid is."

Superman growled as he slowly rose up from the ground. "Hope can never die, Darkseid."

"Oh, but it can." The tyrant of Apokolips stepped foward. "And so will you, Kal-el."

"I beg to differ." A unfamiliar voice rang out.

Darkseid turned to the owner of the voice, eyes narrowed. "And who says so?" His answer was greeted by a fist to his rocky face, making him stumble onto the ground.

Batman and Wonder Woman raised their heads to see Cooler, standing tall as he stared down the mad god. "I, Cooler, say so."

Several days earlier...

A giant robot was wreaking havoc in a country, and four heroes from the Justice League were sent to stop it.

"Ugh, this stupid piece of junk!" Supergirl growled as she flew around, trying to punch the machine. It swatted her aside.

"Seriously, you'd think they make these a little smaller!"Captain Atom fired off an energy blast at the robot, which barely damaged it.

Green Lantern then summoned a construct trying to entrap the machine, but it broke free and swung a fist at him, sending him flying.

"This is just great! I knew I should've stayed home today!" Green Arrow complained as the robot them lumbered towards them, eyes glowing.

Supergirl dove fowards to try to push the robot down, but it once again swung its hand and knocked her into a nearby building. It then grabbed Captain Atom and slammed him down into the asphalt.

"This is bad," Green Lantern groaned. "At this rate, we'll be the ones that need saving!"

The robot moved towards the green-clad duo ominously, but then was knocked backwards by a blast of energy.

"What the-?!" Green Arrow turned to see a strange figure out in the street. He looked like a cross of a lizard and some kind of alien creature. "Who the hell is that?"

"I don't know..." Green Lantern shook his head. He had never seen any alien that looked like that. "But I hope he's on our side."

"So, this thing seems to be strong," Cooler eyed the giant mecha with a small smirk. "But I'm on another level." With that, he then dashed forwards and jumped into the air, raising his fist and punching a hole into its body. The robot then staggered back, sparks flying from its damaged frame.

"What the?!" Supergirl blurted out. "How did he even do that?! I couldn't even lay a hand on him!"

"He's tough, whoever he is." Captain Atom grunted as he got up and watched Cooler pound at the machine, landing dent after dent on its body. Flip. Handspring, Kick. Front jab. Duck, roll. Those were the movements Cooler was using to deal with the robot's attacks. The other heroes were watching as well. Cartwheel over the giant leg. Duck, weave under, handstand and a hard kick to its face. The Arcosian then sprung up and palm-heel striked the robot to the face.

"Time to end this," Cooler then gathered energy in his hands and let loose a powerful blast at the robot, engulfing it completely as it was vaporized into dust. He then floated back down and brushed his hands off. "That was a waste of time." He then turned to leave.

"Wait!"

Cooler turned around to see the flying blonde land in front of him. "What is it?"

"T-Thanks for the help." Supergirl blushed, brushing herself off. "That thing would've done some serious damage if you hadn't came along."

"Yeah, you really helped us out." Green Lantern agreed. "The Justice League sure needs someone like you."

"I have no interest in joining your league." Cooler replied in a firm tone. "I have no need for allies."

"Join the club!" Green Arrow tossed his two cents in, earning him a glare from Captain Atom and Green Lantern.

Cooler then flew away from the four and headed up into the skies in quick speed.

"Hey, wait!" Supergirl shouted after him, but he was gone. "...Great. I wonder if we'll ever see him again."

"I doubt it." Green Arrow huffed, earning him a nudge from Green Lantern.

"Only time will tell," Captain Atom replied.

Cooler sighed. He couldn't believe he outed himself like that to these people. He just wanted to smash that robot and leave. But a part of him was interested in seeing more of these people, and their so-called, 'Justice League'.

"I look forward to see how this Justice League deals with matters like that robot..." He mused to himself as he then descended down in a desolate forest...
