B10 x JLs Chapter 16

Things had calmed down a bit after Darkseid had conceded to Ben 10 after he'd swallowed the Anti Life Equation and survived. A lot of the lower tier Villains went into hiding becuase of it, and gave the league some much needed leg room to work on recruitment and handling more serious threats thankfully. They'd grown it into a much larger network of heroes thanks to this, which meant less work for Ben 10 and Lucky Girl to have to deal with, and giving them more room to breathe. Although the heroes were still trying to figure out their relationship and whether or not they were dating. It didn't help that they were so close, but at the same time they never said whether or not they were dating. In fact that's what they were doing right now, though all of a sudden some strange guy in a lab coat appeared.

"Who are you?" Superman questioned the man that had appeared seemingly from out of thin air.

The man seemed to be disappointed as he looked at his watch not paying attention. "Oh, it seems that I'm a bit early." He spoke as the Flash raced over trying to grab him, only for the man to vanish just before being grabbed.

"What the heck?" The Scarlet Speedster questioned confused as to how the man could just seemingly vanish from out of no where.

"It seems they aren't here at the moment, no matter I can simply wait, being immortal and all." The strange man in the lab coat spoke appearing standing beside the table that some of the female heroes were sitting at making them try to attack the intruder as he simply vanished again.

"How is he able to move faster than the Flash?" Wonder Woman questioned confused since Flash was the fastest person she'd ever know, though XLR8 would for sure give him a run for his money.

"It's called Walking, perhaps you should give it a try some time, good for the system you know." The man spoke now appearing in a nother part of the cafeteira and looking at his watch as if not even bothered by the fact he was facing down an entire league of heroes.

"ENOUGH!" Batman called out with a glare looking at the man not liking the fact that someone like him was making a fool of the heroes.

Looking up at Batman the strange man smiled and spoke. "Oh yes, the old J. L. Batcostume, now that takes me back.. Or would that be forward?" He then spoke to himself looking at Batman's costume. "Time is such a strange concept to wrap one's head around."

"Stop speaking in riddles." Green Lantern spoke making a sphere around the man annoyed. "Now, start making sense."

The man simply smiled at the Lantern and looked at his watch. "But you see I haven't been speaking in riddles at all." He spoke to the group before suddenly vanishing again and reappearing standing behind him. "You simply haven't been listening to me."

"Would you stop that already?" Green Arrow called out annoyed and rubbing his neck. "I'm getting wiplash watching all this."

"A fair critcism to be honest I've been told that more than once." The man spoke in response to the group.

The man continued to make complete fools of all the heroes on the watchtower, and even when some of the others came back none of them were able to help stop him from avoiding capture with ease. That is however, until another hero Booster Gold finally was done with what he was doing on mission and was now headed off to the cafeteria for a much needed break and to get some food into his system.

"Booster." The strange man in the coat spoke with a nod to the time traveling hero as he walked past him.

"Professor." The gold clad hero then spoke with a nod as well, as if he actually knew the man in question.

"Professor?" Green lantern questioned confused as it if, and if so, how exactly Booster knew the man.

"Oh, Professor Paradox, he's a time traveling hero, saved so many universes I've lost count of how many times he appears in the archives." Booster Gold then explained to them finally revelaing to the league just who this man is.

"Yes, and I see you're still using your stolen Legion ring and belt." The man, now known to the League as Professor Paradox, then spoke in response as they heard Ben and Lucky Girl now coming into the cafeteria. "Hello there Ben."

"Hey Paradox, you ready to take us home, or we going to another universe or whatever?" Ben questioned the man casually even though Booster showed clear signs of being afraid of Paradox.

"Yes, I do believe that it's time to go." Professor Paradox spoke with a nod saying he was there to get them.

"Took you long enough, and here we thought you'd forgotten." Lucky girl spoke with a sigh ready to get out of there and hopefully back home now.

"Alright now, off we go ta ta." The Man in the lab coat spoke as he, Ben 10, and Lucky Girl, all left together vanishing in a blue colored energy light.
