When thinking about a crossover the hardest thing was finding two IPs that had at least something in common AND that were funny when put together.
I couldn't get any inspiration when it suddenly dawned on me: the perfect match, two great harvesters of helpless sentients uniting their powers towards a greater purpose; both aiming at making something greater from the flesh of lesser beings trough destruction and resurrection in a different shape; both serving a tyrannical paragon of their kind that refers to himself with majestic plural.
It was then that I knew that the Prince of All Cosmos and the Reapers were born to be together.
