Wanting vengeance from being dropped into the Null Void, a crazed scientist joins forces with a Kryptonian clone as they raise an army of reincarnated supervillains to take down the reconstructed Justice League and the Alien Force all at once.

Alright ladies and gents, you asked for it, and here it is. The new "Justice League: Ultimate Hero", back and better than ever. Read and review!

Aggregor wins and as a result Ben lands in the justice league universe with only his ultimate aliens left he will need to become an all new hero. got the idea from another fanfic who's premise i liked but got me to thinking if Ben is in a universe that no longer has primus how does he change?

Ben Tennyson is running amuck and only the Justice League can stop him.

After a cataclysmic-apocalyptic war, three survivors from another world joins forces with unlikely heroes to help save their world from a multidimensional-superhuman takeover. (Now Readable)

AU. In a world where Gwen Tennyson was the Omnitrix holder, and Ben Tennyson was in the sidelines with Kevin Levin, things were about to get 'Justified'. When a visit from Hawkgirl AND a Green Lantern, Ben is about to discover he was not just partly an alien, but he was a son of TWO well-known heroes. Will contain yaoi somewhere in later chapters. Might X-over with Teen Titans.

When the Joker arrives in the Ben 10 universe and allies himself with Ben's villains, they seek help from the dark Knight himself! But will that be enough for an army of super-powered aliens?

Something goes wrong with Cooper's device. Cooper's device creates a wormhole that sucks Ben and Kevin in and fuses them together before sending them to the Justice League Universe. Harem. Godlike. Grey. Takes no crap Levin Tennyson.

The team known as the Justice League is legendary due to its many famous and heroic members. But what happens when the savior of another universe ends up joining them?

What happened in the Watchtower after Absolute Power. Takes place in my version of RFKC's Misfitverse
