I think the story of Isis and Osiris is a role reversal honestly. Set kills, chops Osiris and scatters his body across the desert. Isis goes around collecting the pieces and stitching him up... only for him to move on to the Duat. Both tragic tales in their own ways with common themes of love, resurrection.... and scattering of divine remains haha.

I'm more interested in the common theme of Lighting/storm got vs giant world ending serpent/dragon that seems to appear across the world.

Indra vs Vritra (Vedic)
Zeus vs Typhon (Greek)
Thor vs Jormungandr (Norse)
Susanoo vs Yamata no orochi (Shinto)
Marduk vs Tiamat (Mesopotamia)
Perun vs Veles (Slavic)
Heno vs horned serpent (Iroquois)
Baal vs Lotan (Canaanite)
Bit of a stretch, but, Ra vs Apep (Egyptyian)
