Ben Tennyson hero of the universe was sent to Japan to finish his last two years of high school in a town called Kouh. There he will meet the High School DXD cast and face many Supernatural threats (Devils, Angels, and Fallen Angels) together.

Ethan Isamu wasn't anything special. He lived a normal life with his friends Issei and Mei, and couldn't ask for much else. But when he suddenly gets memories from another world and an alien device on his wrist, things get a lot more complicated. Especially with Devils, Angels, and Fallen in the mix... (Discontinued.)

With summer vacation right around the corner, that means it's time to kick back and relax, right? That's what Ethan thought, until an alien watch from space crashed in front of him and turned his whole world upside down. With the threat of a galactic warlord looming overhead, and other forces vying for his new powers, Ethan and his friends are in for a wild summer!

Due to a mishap, Ben is sent to a world closely mirroring his own; only with angels, devils, fallen angels and Yokai hiding in plain sight from the rest of the world. Having been thrust into a world full of mythological beings from one full of alien beings, how will our favorite hero deal with it? (NOT MY FIC. ARCHIVED FROM OMNISAURUS)

Ever since he was 10, Ben Tennyson has been having dreams of strange creatures, strange events...and a strange green dragon. No one can explain them; they're a mystery. But when he attends Kuoh Academy, he learns that there's more to his dreams than he realizes. Powerful, original version of Ben Tennyson. OOC and AU. Rated M for swearing, violence and DxD nudity. [Ben x Harem]

Naoto, Issei, and Irina. Three childhood friends were torn apart only to be reunited years later. Naoto gets the Omnitrix while Issei is revealed to be a Devil who wields the Boosted Gear. Irina is now an Angel. This Human, Devil, and Angel trio will change Rias's Gremory and her peerages lives for the better but if you thought that it was simply it...well think again.

How will Ben Tennyson cope with a whole new world of Devils and magic on top of a high breed invasion Will he return as the hero we all know only one way to find out

Banished by his universe, come see what a more bloodthirst Ben will do in a world of Gods, Demons, and other panthions. Will he still be a force for good or fall to the pits of hell. Massive mood shifts and heavy topics may be discussed in the story. Very op Ben(he will still take his wins and losses.) massive harem.

Ben needing a break from it all and trying to actually be human again heads to Japan to finish up his highschool education at a place called Kuoh Academy where strangely, no one seems to know who he is despite him being world famous. There's something freaky going on around this Town. Eh, not his problem, he was on vacation. See no evil, hear no evil…..right?

This is basically a parody of sort based on those Ben 10 reboot planet videos and is based on a AU am working on.

What happens when a man that only has fragments of his memories is thrown into a universe of aliens, monsters, gods and demons with ridiculous powers? This is his story as he tries to survive in a universe that is extremely hostile towards his nature, a nature that was thrust on him due to a playful being of extreme power.

Both Hosts of Ddraig and the Omnitrix, the Crimson Twins are Earth's Mightiest Heroes, who just happen to be Devils under Rias Gremory. However, when one event triggers the beginning of an invasion, the twins must decide which is more important, the World or the people they know. (Fem!Ben, may contain harem, also OOC, just a warning)

During Ben's life in retirement of acting as a hero, he finds that there is yet another threat on Earth. With Grandpa Max gone, he will have no choice but to wield the omnitrix and fight side by side with his friends to defend Earth from this new evil. (Read Hero Time DxD first)

Her name is Izzy) (No Asia) (Rated M Just in case)

Ben was ready to give his life to take down Malware. Expecting the abyss, he found himself in some short of world comprised of mythology. Now he found himself bound to a cute red haired devil girl. "Paradox were are you?"

A hero faces his greatest challenge yet. Will Ben be able to surpass all the odds? Will he come back the same? Will love blossom during his adventures? Will lewd and questioning things happen? Who knows! I'm just the guy asking all these random questions and making you read the story to find out. I do NOT own Ben 10 or Highschool DxD. The answer is yes for the last question though.

Ben Tennyson & Kai Green discover a new world, Charmcaster and Hex manage to follow them in hopes of getting all of the Sacred Gear from the world in order to- you know- become invincible!

The Gods of the DxD Universe foresee the need for a great hero. One that can adapt to all situations. One that has saved his Universe a dozen times. Pity that they decided he'd look better as a girl.
