Are they hero's? (Ben 10 and Jl/YJ crossover)

The big fight

Disclaimer: I don't own anything but the story

They just got off of school and headed home, as they were walking down the sidewalk until they heard something. They heard whispers from the neighbors. "Did you hear, a bunch of weird looking aliens are attacking a city?" A random person said

    That alerted them causing them to rush to their houses and turn on the news. On the news they could see the dnaliens. Anger filled them as they rush to the basement and put on their hero costumes. Ben grabbed ship and they flew over to the city in their plumbers ship and Ben also grabbed their newly hoverboards and weapons .

     The flew at top speeds so they could get there quickly. They landed their ship on top of a building. They got on their hoverboards and flew down with Ben holding ship and throwing them their weapons. They stopped once they could see him.

     Vilgax looked at which hero's have come so soon. He looked at their direction and he can already feel the anger oozing out of their body's. He studied them, having the feeling he knows who they are. He looked at their costumes not recognizing them from the pictures the alien on his shoulder gave him. Until he saw that familiar badge on them from the one place he's seen them. The three idiots who keep causing him problems.

     Once the group of three, saw Vilgax causing the trouble, they already became angry. Ben grabbed his gun and shot him, hitting his shoulder. Vilgax came running towards them. They activated the hoverboards and flew up, making Vilgax miss them.  Vilgax jumped up hitting Gwen and causing her to loose her balance. Gwen regained her balance and shot her gun at him.

    "Why aren't you fighting me? Use your powers, or are you too scared?" Vilgax taunted

     "What happened to our world? Did you destroy?" Kevin yelled

     "Hahaha the little hero's want to know what happened? Well guess what, I don't know!" Vilgax yells back

     "Liar!! You do too know!" Gwen screamed

     Just then the Justice League came flying in, disrupting their conversation. Some of the hero's went to go fight off the dnaliens leaving Superman, Batman and Green Lantern with Vilgax and the three hero's. Vilgax took this opportunity to hit Ben square in the face, now that he was distracted. Ben kicked him off of him and punched him back. Ben was even more mad, first they find out Vilgax is in this world and the Justice League disrupted them, just when they were starting to get answers. Ben ran towards him punching his stomach over and over. Vilgax threw Ben off of him, causing him to crash into a car. Gwen and Kevin ran towards him and went to punch him at the same time.

    The League stood there trying to gather information on who this alien is and why the new hero's seem to know him. Superman wasted no more time and flew punching Vilgax causing him to fly a couple of feet. Vilgax breathed out his cyclonic  winds. While the hero's were distracted, he used his strength boosters making him stronger then before. He ran towards Superman making him fly back quite a few feet back as payback. Then he runs towards Batman but he quickly dodges. The League gets into a battle stance.

    "STAY BACK!" Kevin yelled at the League

     "HIS FIGHT IS WITH US!" Gwen added

    Ben, Gwen, and Kevin got up and ran towards Vilgax but before the could land an attack, he flew up in the sky. He took out his Ruby Ray of Ulo and fired fire laser beans at the three hero's. They dodged the beams just in time. In return Superman, and Green Lantern fired their own beams at Vilgax but it had little to no affect on him.
