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

Who are you guys?

Disclaimer: I don't own anything but the story

Our three hero's are trapped in the neon green dome that Green Lantern has created around them, with Wonder Women and Cyborg at his side. They don't even try escaping, they want to be on their good sides and escaping will just make it worse. They fly up into the sky, until their out in space.

The three of them have their eyes widen at the sight of the beautiful watchtower out in space. They had no idea this is where their hq was at. The three League members each take one of the teens so they don't try to escape. They put them in separate interrogation rooms, and the league members walk out.

Wonder Women, Green Lantern and Cyborg all let out a sigh. Finally, we finally caught them. They walk into the conference room where all the members are waiting for them. All eyes turn on them.

"Well?"

"They're in the interrogation room as we speak." Cyborg states

Everyone let's go of a breath they didn't know they were holding in. They relax their body's. "Alright, I'll talk to the shapeshifter, Manhunter you'll talk to the girl and Wonder Women you have the other boy." Batman said

The two of them nod their heads in agreement and the three of them walk out. The rest go back to their towns or homes and do whatever. Batman walks into the room with Ben, Manhunter goes in the room with Gwen and Wonder Women goes in the room with Kevin.

Batman sits down. "Alright start talking."

"Yo! I'm Ben." He says

Batman gives him the famous bat glare and makes Ben flinch. Batman smirks knowing he scares Ben. "First off Ben, how come we can track when you shape-shift but not for the other two?"

"Oh that's because they actually have powers due to being half alien, I on the other hand can shape-shift thanks to this watch." He lifts his arm and shows him the watch. "I found when I was 10." Ben explains

"If you have had this since you were 10, how come we didn't hear about you until now?" Batman asks

"That's because I'm not from this universe, I'm from a different world." Ben explains like it's no big deal

Sigh. "Ok so we know about a handful of the aliens you can change into, how many more can you change into?" Batman ask one of the biggest questions he has.

"Um I lost count after 30 but I think I change into more then 70 but I haven't collected them all yet, I'll be able to transform into a million." Ben tells Batman

    Thai made Batman raise his eyebrows, in shock. They've only been able to see a handful of them and he probably wasn't going all out on them.

    "Ok then, now why did you guys come into this world?" Batman ask

     "Well we were in the middle of a battle against Vilgax, you've met him before. We were on his ship when we fell out, Gwen and Levin were unconscious but I was still awake. We were falling out in the sky near Mt. Rushmore and we were going to land there but this portal called the convergence appeared and next thing we know, I wake up in Metropolis, Kevin is in Gotham and Gwen is in Washington D.C." Ben explains
