Sorry for the wait, and this isn't the best chapter but oh well, I kind of rushed this. Hope you enjoy!

3. Of Strange teenagers and Fire tornadoes

With all of the league's and the monster's attention towards the sky, they did not notice a large shadow appearing on the side of a building, before out stepped a truck-sized hellhound, which seemed to look average-sized around the other hellhounds. Though the odd thing was, a boy was sitting on the hellhound. He wore all black beneath his black armour, and his skin was a pale as the crescent moon. A skeletal-like war helm was perched on his head, but you could still see his sharp obsidian black eyes as he drew his midnight black sword. The league turned their attention to him, while some monsters growled at him with pure hatred, though some looked fearful.

However, this did not hold the monsters' and the league's attention as something else flashed down the street. Whatever it was, it was fast, very fast. It was almost as fast as the Flash as is zoomed past the bewildered looks of the monsters and it skidded to a halt next to the boy in black.

It turned out to be a girl on a horse, but smoke rose from the horse's hooves as it rose its head proudly while the girl jumped off. She wore a purple t-shirt underneath what looked like golden armour, as a war helm that looked like it was encrusted with golden jewels was perched on her head. Curly brown hair stuck out of the bottom of the helm as she reached down and unsheathed a short sword that was strapped to her leg.

Suddenly, a large red dragon descended from the clouds as if roared at the enemy pale blue dragons, scaring them half dead while some roared equally as fierce back at the red dragon.

A horse made of nothing but storm clouds landed on the pavement and made a low and aggressive growling sound that rivaled a giant's growl. Two figures leapt off, a boy wearing a purple t-shirt, with a war helm with lightning designs on the side as he flipped a coin in the air, but when he caught it, instead, he caught a golden sword. The girl wore a war helm with flowery-like designs, but not too girlish as she unsheathed a very, very shiny dagger. She wore an orange t-shirt beneath her bronze armour instead of a purple one.

A second horse made of storm-clouds descended and hovered right next to the red dragon, and on it, perched a girl who wore punkish clothes underneath bronze armour. She held a long spear in one hand, and a shield on the other with the terrible face of Medusa on it. Though there was a quiver full of arrows strapped to her back with a bow as she wore a similar war helm to the boy's that got off the first storm-horse.

A second dragon descended from the clouds, though this one was mechanical and was made of bronze as it landed on the pavement with a loud thrud! The boy that sat on it wore a war helm with fire-like designs on the side; an orange t-shirt was underneath his bronze armour as he adjusted his tool belt around his waist and took out a bronze hammer.

The last shape plummeted towards the ground as it quickly stretched out its wings just before it crash-landed. It turned out to be a black Pegasus as two figures quickly got off and the boy nodded towards the Pegasus who flew off.

The boy looked the oldest of the others as he adjusted his war helm on his head that had wave and sea-shell like designs on the sides. He too, wore an orange shirt underneath his bronze armour as he took out a regular ball-point pen, though when he uncapped it; it turned into a metre long bronze sword. The girl next to him wore an owl-shaped war helm as she unsheathed a dagger that was strapped to her thigh; she wore the same as the boy: orange shirt with bronze armour.

The boy with the pen-sword quickly looked around, making sure the rest of the teens were there, before he yelled: "For Olympus!" and charged into battle.

That broke the spell.

Almost immediately, the monsters charged at the teens, while the leaguers looked at each other confusedly. Hawkgirl merely shrugged before she charged into battle, Superman and Green Lantern following not long after. Batman began shooting at the dragons, though the red one seemed to be quite smart as he dodged all of them and seemed to not do any rampage like the rest of the enemy blue dragons.

Martian Manhunter helped the girl with the spear, and when she missed or when she accidently dropped it, he would levitate it back to her. She would then give him a thankful nod before going back to battle.

Meanwhile, the Flash and Wonder woman hurried to the biggest problem they had at that moment: the hydra. However, when the Amazon princess and the fastest man alive arrived, they saw that the boy with the tool belt with his arms on fire as he taunted the beast.

"Ever heard of breath-mints bro?" he smirked as the hydra roared at him angrily.

"Hey, I remember you." exclaimed the Flash as the boy turned around quickly.

"Oh hey." He said casually, waving his flaming arms before turning back to the monster.

"I have an idea." said Wonder woman as she quickly flew towards the nearest abandoned petrol station and took a can of petrol and poured a ring around the monster.

"I'll make sure to pay the owner back later." She muttered to herself, before flying back towards the flaming boy and the Flash.

"While I keep the monster distracted, can you light the petrol on fire?"

The boy seemed to hesitate, before he understood the plan and nodded.

"After that, Flash, go run around the monster." she stated.

"Yes, ma'am." he said, before the boy with the tool belt also saluted mockingly with a smirk before Wonder woman rolled her eyes and flew over to distract the hydra.

The boy snapped his fingers, before the petrol lit on fire completely, forming a ring of flames around the hydra. The Flash then run around the monster, the wind causing the fire to rise as it formed into a fire-tornado. The monster barely had enough time to yelp before it disintegrated into nothing but golden dust and ashes.

Green lantern rushed towards the closest and most threatening thing he could see: The Minotaur. But when he was barely 50 metres from it, the boy with the pen-sword appeared right in front of the Minotaur and smirked.

"Wow Beef Boy, seriously? You couldn't at least squeeze in a 5-minute shower before you came? 'Cause you still stink and you really need a change of clothes, because loin-cloths and leather belts were so 2000BCE."

'Beef Boy' roared and charged at the boy, but just as he and the beast was about to slam into a beef and boy sandwich, the boy rolled out of the way just in time and yawned.

"You sure have gotten slower, I can tell you that."

But from the corner of GL's eyes, he saw a dog-like creature notch and arrow and it was aimed at the boy's head.

"Percy, look out!" yelled the girl with the owl-shaped helmet as she ducked and sliced a snake-lady.

Too late.

The arrow was already coming towards him at top-speed, though just as it was about to impale itself into the boy's chest, a green bubble formed around said teen as the arrow bounced harmlessly off the sides.

The boy, looking confused as he looked at the arrow, but he then noticed the green bubble around him and he turned to Green Lantern. A smile grew on the boy's face as Green lantern descended and landed next to him.

"I'm guessing you remember me?" smirked the boy as Green lantern rolled his eyes and was about to reply, but the Minotaur had other plans.

It charged at the two of them again, fortunately, GL was ready as he then formed a large green fist and punched the Minotaur in the nose, causing it to stagger backwards momentarily.

"No, that's not going to do." commented the boy as Green lantern formed a sword with his power ring.

The boy quickly raised his sword and slashed down the nearest snake-lady; it crumbled to yellow dust but its spear was left behind.

"Here, take this." He commanded, picking up the spear and gave it to Green lantern.

The boy then sprinted over to the Minotaur and taunted it. GL realised what he was doing, and rose his green-willpower made fist, spear in it as he got it above the beast's head, and brought it down.

Eventually, with the help of the 9 strange teenagers, all of the monsters were sent back to Tartarus. The Justice League and heroes of Olympus then began cleaning up.

"I suppose you probably have some questions." stated the boy wearing a purple t-shirt with electricity blue eyes beneath his helm.

"Duh." said The Flash.

Batman shot him a Bat glare as he then turned to the 9 heroes and his eyes narrowed into tiny slits.

"Yes. Explain. Now." He barked.

As you know, dear reader, practically everyone in the Batclan absolutely loathed not know things, so it was reasonable for the Dark Knight to be pissed-off. The teens seemed to be intimidated by the large bat, everyone but the younger boy in black as he spoke.

"Sure we will, but can we talk somewhere else where we can sit down? Because we really have a lot of things to talk about."

Batman glared at him, before he turned around swiftly and headed towards their spacecraft, the others following closely behind him.

A/N Yes, I figured I was going to write this like I did for the first chapter, where I focus on with specific characters in separate scenes. But I was feeling lazy and, well, couldn't really be bothered. Don't worry though, because this is just a starting battle, I won't do it in detail. Thanks for Reading! :D
