Lovehammer

Lovehammer is a crossover between Warhammer 40 000 and Sailor Moon. It's based on the image of the Emperor of Mankind finding the infant Sailor Moon and bringing her up to be a warrior princess of the Imperium. There are three significant versions of the "main verse", so to say: Arkado's, which takes place in the 40th millennium and focuses on Commissar Ciaphas Cain and Saturn; Bpen's Scattering of Serenity, which shows the upbringing of Sailor Moon by the Emperor and the galaxy after the inevitable Heresy. Finally, there is the last version, which is more of a consensus, as it is written by several authors at once.

Currently, there are also four spin-off universes: Toy Soldiers, where Beryl learns the meaning of Butterfly Effect; Karmaverse, where Primarchs are reincarnated through Serenity's spell; an unnamed 'verse, where Serenity ends up on Colchis and brings Lorgar up; and Heresy & Rebirth where Leman Russ and Corax recover the reincarnations of their brothers in the 41st Millenium.
