One great Wonder Woman and Hades fanfiction could be about them teaming up to save the underworld from a greater threat. Maybe a powerful demon is trying to take over and they have to combine their unique powers. For example, Wonder Woman's strength and combat skills along with Hades' control over the dead and underworld magic.
Often, their powers interact in a way that creates a balance. Hades' ability to manipulate death and the afterlife can be offset by Wonder Woman's life - giving and heroic nature. In some stories, they might even combine their powers to defeat a common enemy. Say, Hades could open portals to different parts of the underworld to trap the enemy while Wonder Woman uses her strength to push the enemy into those portals.
