The list of WIPs, for you to read and and demand I write more of. Non-exhaustive and likely to be updated as time goes on.
Naruto
Hand over Hand Over Hand - Ongoing - Madara/Hikaku/Tobirama. Omegaverse arranged marriage slowburn, where high ranking alpha/omega couples sometimes bring betas into their marriage. [Tag]
Foxfire - (possibly) NaruSasuSaku. Yokai are real and the tailed beasts were given power by the sage rather than created by him, and Naruto gets raised by a couple of kitsune. [Tag]
Canon Rewrite - This is the devil speaking to me and (@firecoloredwater). Naruto was raised by Hiruzen('s hired help), Itachi didn't kill all of the Uchiha and is the clan head. Sakura is an orphaned Senju. And more! Planned to be a series of illustrations and snippets rather than a full fic. [Tag]
The Academy Three - Kakashi sends Team Seven back to the academy, and Iruka picks up his slack. [Tag]

Woodland Succession - MadaTobi - Hashirama has been acting odd -- Odd enough to leave his brother tied up like a gift for the Uchiha to capture. Tobirama is willing to work with even the Uchiha, if it means saving his brother. [Tag]
Tengu AU - MadaTobi - A comic, basically a howl's moving castle AU. Madara is the lord of the mountain and Tobirama is his yearly sacrifice. Neither of them care too much about such things. [Tag]
Trust in Reverse - IzuTobi - The daimyo of fire forces an arranged marriage between Izuna and Tobirama that he clearly expects to fail. They are spiteful enough to make sure it doesn't. [Tag]
Brothers in Bond - IzuTobi -Tobirama and Izuna are captured and put into captivity together, which leads to, ugh-- mutual understanding. [Tag]

The Senju Ghost - IzuTobi - Izuna doesn't believe in spirits until he gets caught by one. He hates it, but what he hates even more is Tobirama showing up an announcing that it's his job to get Izuna free. Some things already written in this AU here and here. [Tag]
Unnamed #1 (Tobirama Memory Loss) - IzuTobi - Tobirama is captured by the Uchiha. Only, he seems to be suffering from some kind of memory loss. Izuna puts himself in charge of getting information out of him. [Tag]
Unnamed #2 (Nowhere Else to Go) - IzuTobi - Izuna recognizes and purges Zetsu's influence from himself, but he can't free the rest of his clan. Circumstances lead him lead him to seek help from Tobirama. Which leads to a stupid adventure, and misunderstandings on a global scale. [Tag]
Crane's Return of a Favor - HikaTobi - Tobirama has crane summons. Someone else does too. They become pen pals, of a fashion. [Tag]
East of the Bend - HikaTobi - While his brother is off making friends, Tobirama makes a friend of his own. They're a bit more pragmatic, when it comes to making peace. [Tag]
Unnamed #4 (Political Hostage Hikaku) - HikaTobi - Hikaku led the Uchiha defectors after Izuna died. Now that Madara has finally made peace, the only way he can think of to save himself from Madara's wrath is to make himself too politically valuable to kill. So he marries into the Senju. [Tag]
Unnamed #5 (Oops! Arranged Marriage) - HikaTobi - The Uchiha offer Hikaku to marry Tobirama fully expecting the offer to be rejected. It is not. [Tag]
Unnamed #6 (Concubine Hikaku) - HikaTobi, HashiMada - Madara refuses to accept peace, and so the Uchiha are defeated. Unwilling to kill Madara, Hashirama claims him as a concubine. In order to support his brother, Tobirama picks an Uchiha to become a concubine of his as well. [Tag]
Unnamed #7 (Pokemon AU) - Wherein Hashirama has gone off to prove that this new gym challenge thing is worth it, Tobirama's first pokemon hates him, and there's a magikarp in the garden pond. [Tag]
These three are in the same continuity:
(Ambitious uses for) Hands and Tongues - HashiIzuMito - Izuna is healed by Hashirama, leading to a peace he doesn't agree with at all. He decides the best thing to do to ensure his clan's safety is to get blackmail on the hokage by seducing him and/or his wife. [Tag]
Like Gravity - HikaTobi, Hikaku is the only Uchiha who is willing and able to work with Tobirama. He decides that he's going to go into it with an open mind. Slowburn.
A Place to Fall Into - MadaHikaTobi - Madara finds himself lonely, in a world at peace. It takes a few realizations before he understands he doesn't have to be.
Desert Spring - Tobirama kills his father on accident and flees to wind country, where he just so happens to fulfill some folkloric prophecies. He's 14, he doesn't want a harem, and he's only organizing the coup as a favor, honest. [Tag]
Everything Stays/Everyone Lives - The Everyone Lives AU where nobody knows everyone lives. Completed fics are in this collection (And in a different but adjacent AU by Para Here). Madatobi get married early on and remain so in the background. [Tag]
The Necromancer's Apprentice - Edo Tensei is a little nicer, and Tobirama makes a name (and a lot of money) for his clan by allowing the rich to speak to lost loved ones and getting confessions from the dead. When peace happens, the Uchiha elders demand that Tobirama takes on an Uchiha apprentice -- which to the Senju, is functionally the same as having him adopt the child. [Tag]
Unnamed #8 (The Brothers Patricide) - Hashirama knows that he needs to kill Butsuma sooner rather than later. He knows that Tobirama is loyal to him and would never agree. Tobirama knows that Hashirama is too naive to see the ruin Butsuma is leading their clan towards. He needs to kill his father before it's too late. [Tag]
Plant a Plum Blossom (Formerly: Unnamed #9, Tobirama buys a courtesan) - Outsider POV. Tobirama goes to a courtesan to keep cover on a mission and enjoys her company so much that he buys her contract so she can work for him -- as a research assistant. [Tag]
Unnamed #10 (Haku Timetravels) - Zabuza dies with an Uzushio scroll in his pocket, not that Haku knows anything about that. He just knows that he's woken up in the past, and that he's skilled enough to attract attention there. [Tag]
Unnamed #11 (Touka Saves Izuna) - Upon seeing the Hirashin for the first time, Touka goes out of her way to capture Izuna alive before it can be used on him. [Tag]
Unnamed #12 (Uzumaki friends) - Tobirama's classmates in the sealing arts come to visit Konoha. Being Uzumaki, they opt to cause entirely new varieties of trouble. [Tag]
Unnamed #13 (Hikaku Goes to the Senju Orgy) - Hikaku/Hashirama,Tobirama,Touka,Mito, various unnamed senju..... - See, Hashirama has this great idea that if everyone in the Senju could potentially be the kid's parent, they'll be forced to treat it like it's theirs. All he needs is a volunteer.

Ghost in the Machine - Moshang - Mobei Wang does the reasonable thing when waking up in bed with an unknown human: he kills the man on sight. Unfortunately, this doesn't do anything to keep the cultivator from continuing to bother him. ... Excuse me, System! What do you mean there's no penalty for failing mission: survive!?
On Brood Parasitism - ZZL/Luo Binghe's Mother - When Junshang casts him far away from his sealing, all Zhuzhi-lang has left to do is search for answers. He finds them.
