A story idea open to anyone about a fused Nasuverse and HPverse. Let me know what you think!

Harry Potter didn't think he had any family left other than the Dursleys. Shirou Emiya didn't think he had any family left after the Great Fuyuki Fire. When these two meet, the world will never be the same. AU beginning with the summer before 3rd year. Timeline has been moved forward 10 years to better fit with Fate/Stay Night.

(Inspired by the drabble Cascade Effect by sakurademonalchemist, and written with permission) Like ripples on the surface of the water, a single act alters the flow of history. A young girl's disappearance leads to forces beyond comprehension to move on Earth, while her Servant does his best to keep his young master alive in a grail war gone horribly wrong. Multi-crossover mishaps.

In the middle of a war, an attack occurred, A miracle happened along with a tragedy. These are the catalysts. The beginning of the creation of a person of infamy and fear. the beginning of the hunt.

Zelretch decides that Fujimaru alone is not enough to save humanity, so he kidnaps Harry Potter and dumps him on Chaldeas front door.

Heroic Spirits, legends made flesh, have not walked the world for centuries. However, Voldemort, to further his conquest of the magical world, uncovered a ritual and summoned such a warrior. It is up to Harry Potter to act as the sword and shield of the world against the horror Voldemort has unleased, but he won't have to do it alone.

First Fate/Stay Night crossover. Only familiar with Zero, UBW and some of Case Files Stories have an element of truth. Something Dudley will find out the moment those three blood-red marks appeared on his hand. He will need his cousin's help, more than ever.

an accident during the summoning in Chaldea reveals a surprise

Zephyr Potter, the soon dying and magically crippled brother of the girl who lived, decided to free his sister with the help of a mysterious otherworldly entity claiming to be a god. The catch? He had to save the multiverse. A good deal in his book, with the safety of his sister at stake. But soon Zephyr will learn that things rarely go like they are supposed to. Multiverse, harem

Waking up in an alternate universe where the wizarding world still exists should bring about a sigh of relief to Harry. However, familiar people behave differently and everyone seems to be obsessed with preserving mystery. At least Harry wasn't famous. . . Yet somehow he still manages to land himself in more trouble. Juggling two wars is not an easy feat even to the boy who lived.

She was 5 when she happened to find herself on the streets of London. Little did she know that this would lead to opportunities like no other. She got a cool dad out of the deal as well. Fem Harry!

Sequel to Broken Chains. Shinji's achievements at the Potions Championship were not without cost, as his criminal behavior has finally caught up with him. To avoid certain death, the Boy-From-the-East takes a desperate gamble, staking his life and freedom on being able to single-handedly face down the forces of an invading army, but even victory will come at a very hefty price...

Harry Potter wasn't a normal child, a normal child isn't raised by a Dead Apostle in a reclusive mansion in the woods. A normal child doesn't look at humanity in such a detached way. Harry wasn't sure if he wanted to be a normal child the same way he wasn't sure of what was going to happen in Hogwarts. Dead Apostle Mash. Harry won't be overpowered.

Harry kills the Basilisk in the Chamber of Secrets. However, the spirit of the beast doesn't want to leave just yet. Together Harry will uncover more about his lineage then just his parents. Also he will get involved with those that are as separate as the Wizarding World. Will Harry be strong enough when he has to choose which cup he competes for? Double Trouble indeed.

Book 2 of the Swords and Sorcery series. Shirou and Iris continue on to their second year at Hogwarts with new friends and potential enemies showing that perhaps Shirou is not as far from home as he thinks.

Third Fang's FFD Shirou, Saber, Illya, and Assassin are commissioned by Zelretch to go to the world of Harry Potter to kill Voldemort and Protect Iris Potter. (Fem Harry) [Rated M for abuse, emotional trauma, and a lot of killings (Because this is FFD Shirou we're talking about, the guy goes nuts with hidden explosives whenever he gets stressed out, so yeah.)]

EMIYA got send to another world by some unknown way, now he will start a new life, but... will he ever stop being a hero?

Shirou Emiya had not been ready for the Clocktower. He lacked roughly seven years of the background required to do anything of value there, and the attempt to teach him was cutting into Rin's own research time. So Zelretch decided to send the boy away to another world to complete his 'magical primary school education'. Not like he has the power to say no.

The ICW has enough with the problems in Hogwarts and sacks Albus Dumbeldore as the Headmaster. Instead the Director of Cheldea, Ritsuka Fujimura takes over the school on behest of the ICW. Rose Potters 5 year will be far from what she expectet and it remains to be seen how Chaldea will help in the War. (Dumbeldore, Weasley, Granger Bashing)

Shirou Emiya is reincarnated as Ron Weasley after being killed by Gilgamesh during the events of Unlimited Blade Works. He is determined to not waste this second chance in life and protect his new family no matter what.

Rin Tohsaka screwed up in her magical experiment and found herself in another Earth similar, yet different, from her own. Finding no way home, she started to adjust until she could return. One accident leads to her becoming new Professor for the Defense Against the Dark Arts at Hogwarts. This is her story as a teacher of Hogwarts!

this is a re-editing of the shadow walker story that I have been wanting to do that should (hopefully) make the story fuller and fill in the gaps that were their before

Shirou Emiya was transported to another world as a sick prank by the Wizard Marshall himself. Now he have to be with new ally against the forces of evil with 'The Girl Who Lived

All my life, people have placed their expectations upon me. They would have me believe I failed. Cowards. What right do these mongrels have to pass judgement upon me. The only right these people have. The only right I allow them. Is to stand in awe and be humbled if and when I deign to stand as their salvation. Gaze upon my wonders. For I sit upon the Throne of Babylon.
