Marvel Universe (19th May 2015, Baxter Building)

Reed Richards typed frantically as several machines that he'd created beeped and sung with the sound of alarm. His machine the 'Portal Detector' nicknamed 'Port' could detect any rip in space and time on the planet. Tony Stark had been helpful and giving Port an A.I upgrade so that it could communicate with everyone.

"Reed. There is another portal opening. The sixth this week." Port said in a monotone way, Reed ignored him at first, before wiping sweat from his brow and stretching his arm all the way to the other end of the room to pull a black board closer to him, he began to work on several calculation while making various mumbling sounds. Reed could stretch his body to great distances due to exposure to cosmic rays while he went out into space, he was also known as Mr. Fantastic.

He dropped his line of chalk.

"It's right above us..." He mumbled before standing up and stretching himself over to the other side of the room grapping more of his previous calculations, he quickly read his notes and scratched his chin. "If my calculations are correct then this portal should be open for..."

"Another forty-eight hours sir." Port interrupted, before he silenced his alarms, "Do you want me to call the Avengers?" He asked

Reed paced for a few moments before snapping his fingers together and answering, "Yes! But also call Charles Xavier, have him send over Jean Grey and Iceman, maybe they could help." And without another word he left Port to get on with it.

DC Universe (19th May 2015, Batcave)

Bruce Wayne sat looking at his monitors, Alfred was upstairs making tea and his son Damian was training vigorously to his side, dressed as Robin, beating a dummy to a pulp. Selena Kyle had popped over too; Bruce and her were lovers by day, but not always friends once they donned their masks. She leaned over him and pecked his cheek,

"What's bothering you, Mr. Wayne?" She teased, Bruce had been especially tense recently, for some reason that was unknown to her, he finally cleared his throat after a long silence.

"For the past several weeks there have been portals opening, all over the world, Clark first made me aware of them two weeks ago, but there's no pattern that I can see so far." He sighed, "And one's opened up tonight in Gotham." He sighed after his last sentence.

Selena purred and stroked his face, "Easy Bruce, I'll get dressed up and investigate it for you, seeing as you've just put Scarecrow away for the fifth time this month. Get some rest." And with that she was gone, but not before placing a kiss on his cheek.

The darkest parts of Gotham were the worst, any part of Gotham was dark, but some places were just Hell painted a different shade. Catwoman prowled across the rooftops of the location of the portal, not nervous at all. She saw a group of young men laughing with each other, and she would've ignored them if she hadn't heard 'purple portal thing.'

Gus was a young black man, and he was in the alley with his two friends Kyle and Greg, they'd been walking home from a movie, when they'd ran into purple portal like thing, it glittered at the side and shone bright in their eyes, it was almost blinding. They were trying to dare each other to run into it. Until they heard the crack of a whip. Kyle had been thrown to the floor and Greg kicked down there too. Gus was shocked to see Catwoman seductively walking towards him, she cracked her whip against the floor before licking her lips and indicating for Gus to go away. And he did, as he pissed himself Gus ran.

Marvel Universe (19th May 2015, Baxter Building)

On the roof of the Baxter Building Reed and his wife Susan stood, with Captain America, Iron Man, Jean Grey and Iceman. The portal was convulsing and shining brightly. Captain America watched it with slight amusement. Before Iceman cut it

"Look Mr. Fantastic this thing is pretty and mysterious but what can Jean and I do about it?" He said crossing his arms, Bobby Drake was blonde but wore a bandanna, white top and denim jeans with a leather jacket he was cool.

Iron Man took off his helmet and nodded in agreement, "I agree, there's nothing we can do, maybe monitor it, hey Reed how's the A.I treating you?" They all waited for an answer, all looking at Reed, except for Captain America who stood up and sighed.

"I don't like it, Reed you and I can watch over it to see if anything happens." He said, "The rest of you go home and wait for any news."

"What are you guarding it for?" Jean asked raising her eyebrow; Captain America looked at her,

"In case anything comes through." He stated.

After nearly two hours had gone past Steve was ready to leave, nothing was happened, but he was Captain America, he had to protect everyone. Reed had gone in earlier with Tony to try and create a device to close the portal with Ports help too.

Snap. Crackle. Pop!

A woman fell out of the portal, she reminded him of the Black Cat, did she get a new look? He cleared his throat and the woman looked up, it wasn't Black Cat.

"Who are you?" Captain America asked while raising his shield, the woman stood up slowly looking around, she looked confused, she looked at him with a small smile though.

"Name's Catwoman." She looked at his shield, "I know how you want to play."

Without knowing where she was, she sensed she was in danger, she pulled out her whip and cracked the whip and pounced.
