The Watchtower, Outer Space, DC Universe

Peter Parker could not believe that he was not really an unofficial 'young Avenger' for that long and yet he has already gone to an alternate universe. At least he met a friendly face in Kara before any of this world's villains had got to him first. She had beamed him up to a satellite base called the Watchtower. "Your world's main superhero team has its own satellite, why don't the Avengers have one of those... or do they and Tony has not told me that yet? I think Captain Marvel has her own..." Peter wondered as Kara had brought him to the League members who were going through diagnostics through a machine.

"You have a Captain Marvel on your Earth whose a she?" Kara questioned intrigued and Peter gave a grin to Kara behind his mask, Kara thought of the hero known as Captain Marvel that she had heard of. He looked like Kal and had similar powers but Kara could not help but think of how he acted just like a kid.

"He seemed to be like the Humans on our Earth except for strands of genetically altered Spider attributes in his DNA which I assume his powers must come from." J'onn told them once the scan of Peter was complete. "He should be fine though I am not sure when we would be able to find a way to send him back to his own Earth." J'onn said and the others looked to Peter who could tell that he was panicking in his head.

"Aunt May is so going to be worried! Maybe the Fantastic Four and the Avengers could find me again..." Peter thought but Kara gave a sympathetic smile to Peter as she put her hand on his shoulder and he smiled back in return to a disapproving eye from Clark.

"Alternate Earths, I don't doubt he is a hero where he comes from but I still remember the last time we had to deal with the Crime Syndicate..." John Stewart said remembering their counterparts from what was like a reverse version of Earth and he had to deal with Power Ring, an evil cowardly version of Hal Jordan.

"Spider-Man, until we can find a way to get you home, you are welcome to stay here at the Watchtower." Clark told Peter who seemed to be looking better. "Now you think you can tell us a little about yourself." Clark asked.

"...well not a lot of people know about my identity back home but since this is an alternate reality..." Peter said taking of his mask and most of the League members seemed quite taken aback at how young Peter was under his mask but Kara thought he was kind of cute. "Well my name is Peter Parker, fifteen years old, I got my powers from a spider bite at a science experiment I was attending... I learned with great power comes great responsibility and I have been Spider-Man for a year or something." Peter told them.

Kara knew there were younger heroes on this Earth like Firestorm, the Teen Titans and the Blue Beetle but she believed this was her first time meeting one. "Well I am Kara Zor El or Supergirl, one of the few survivors of planet Krypton along with Kal; I escaped in a rocket pod that spent years in a dimension frozen until it came to Earth. My powers came from this planet's red sun and gravity." Kara said introducing herself and though Peter was a bit surprised that Kara was an alien he did not think too much about it.

"I think back home there are alien Avengers, we have Thor the Norse God of Thunder as a member and my mentor Iron Man told me he is an honorary member of a team of alien heroes called the Guardians of the Galaxy." Peter told Kara who was glad that revealing she was an alien did not scare him away.

Stryker's Island Penitentiary, Metropolis, DC Universe

Stryker's Island Penitentiary the prison for criminals in Metropolis and liked Arkham Asylum in Gotham City; it was equipped to hold the super powered criminals. In one of the cells glaring at everything around him was a purple haired man in an orange jumpsuit; this was happening as Kara was bringing Peter to the Watchtower, this man was Manchester Black who was the leader of the super powered violent team of superheroes known as the Elite.

"...I should not be in here..." Manchester seethed remembering how he and his team were defeated by Superman and there was a block in his brain that was shutting down the part that gave him his telepathic powers. "They need me out there doing what they can't do..." Manchester continued ranting to the tutting sounds of the man in the cell next to him.

The cell was occupied by a man in a black armor that was controlling the radiation he emitted; the staff had scientists who put blocks on his suit preventing him from using his powers along with several devices in the machine to prevent him from trying to escape. "Wish they did not stick me next to the leader of the arrogant idiots who thought they could replace Superman..." the man taunted Manchester.

"Shut it Krull, at least my team did not get beat by Superman's baby cousin." Manchester told the man called Ben Krull who glared at the wall separating the two. Ben Krull was a supervillain known as Reactron and clashed with Supergirl more times than he did clash with Superman. Then suddenly in their cells they saw a portal come out (one in both of their cells) and they each popped out a light blue glowing fragment.

As the alarms went off they both picked up the fragments...

Appearances

Manchester Black: Superman V the Elite (my favourite DC Animated movie)

Reactron: Supergirl TV series (I really like the show but I admit I did not really like how they just relegated Reactron to a one episode baddie when apparently in the comics he was the closest thing Kara had to an arch enemy)
