"Hmph. This could be a good way to kill time." He then flew towards the chaos unfolding in the city.
Meanwhile, Supergirl was flying around, hearing the news of the lizardmen attacking the country of Bilaya, with fire breath and razor-sharp claws. "I just hope I'm not too late..." She pushed herself to go faster.
A lizard roared in pain as it flew into a car, its arm broken as Cooler began to deliver vicious kicks and punches to the bipedal reptiles, performing a spinning kick onto one's head, knocking it unconscious. He then slammed his fist into the gut of another lizardmen, making it fall over backwards.
"Anyone else?" Cooler demanded.
A blast of fire struck him, forcing him to block the attack. As it abated, Cooler gathered some energy and blasted it towards the attacker, causing it to obliterated into ashes. "Lucky shot." The Arcosian spat, brushing himself off.
"Hey!" A familar voice shouted, causing him to turn to face Supergirl as she landed down onto the streets. "You're the guy from yesterday. Why did you run off?" The blonde asked, curiosity written on her face.
"I owe you no explantions." He cooly spoke.
"Yes, you do! We could really you your help, you know-" She was cut off as a huge lizard bitchslapped her into a building, making her cry out. Cooler merely smirked. "About time a real challenge came." He cracked his knuckles as he then charged fowards at his opponent.
Supergirl groaned as she got up, rubbing her head. "Owww... I can't believe I didn't notice that big guy coming." The blonde alien shook her head and saw Cooler pummeling the reptile like a punching bag, with the beast managing to get in a few lucky hits. Cooler backflipped and jump-kicked its snout, then groaned as it grabbed his leg and slammed him down into the pavement.
"Hey! Leave him alone!" The Kryptonian girl snapped as she flew towards the lizard king and tackled him. She raised a fist to strike him, only for the beast to breathe fire upon her, causing her to cry out in pain. "Y-You wanna play with fire...?!" She then took a breath and blasted the reptile with her icy breath, making it growl and back away. "How do you like me now?!"
Cooler grunted and forced himself up, gathering energy in his hands. "Back away, girl!"
"What are you-" She was cut off as The Arcosian blasted the giant lizard, sending him crashing into the building and watched him slump down into unconsciousness. The blonde gaped at the alien as he panted heavily. "Hey, are you alright? Don't worry, we can-"
"I don't need your assistance. I can get by fine on my own." Cooler snapped, moving away from her.
"Are you kidding? You just got sidewinded by that crocodile! You need-COME BACK HERE!" Supergirl shouted as Cooler flew into the heavens, ignoring her as he left the city behind him. He did not need the help of that girl or any of the other heroes.
Meanwhile...
Batman had watched the whole thing. And he did not like at what he saw. This Cooler had destructive powers, and seemed to relish causing havoc, but he hadn't hurt any civilans. Nevertheless, he wasn't someone to ignore.
"Cooler, I'm watching you." He spoke, observing the monitor in his brooding posture.
