Dogpile

Question: I’m running a game that, rather than dealing with the Titans, involves a cold war between the Dodekatheon and everyone who hates them, and suddenly becomes violent due to the recent discovery of Metis’s son outside of the Dodekatheon’s sphere of influence. My problem is that I can only think of two pantheons that would be angry enough to go to war with them: the Nemetondevos and the Elohim. Are there any other pantheons that would be angry with them? Would they have any allies?

Oh, man, a Dodekatheon hate-fest? Invite us!

The biggest pantheon I can think of that should be involved here is the Pesedjet. The Egyptian gods are millennia-long frenemies with the Dodekatheon; sometimes they have positive commerce and even share myths, and sometimes they fight over territory and call each other racial slurs across the Mediterranean. There was a long history of argumentative interaction between the two even before Rome sailed across the water and imposed their own rulers in the Ptolemaic dynasties, and there're almost limitless possibilities for who wants to do what in this situation. Is Isis cool with the Greeks, who had temples to her in some of their own territories? What about Horus, who saw his rightful line of pharaohs replaced by invaders from the north? How does Bastet feel about Greco-Roman influence basically transforming her from a sun goddess into a lunar deity, and do the highly regimented death gods blame foreign burial practices for causing the erosion of their own process for the afterlife? Do Thoth and Hermes get together and laugh about the idea of Hermes Trismegistus, or is one or the other or both of them pissed off about the situation?

It's a total powderkeg of a pantheon when it comes to the Dodekatheon, and you can never tell if they'll be on their side as ancestral allies, undermining them as long-time enemies or split, with some of the gods going one way and others another (what a surprise, the Egyptian pantheon has disagreement among the ranks!). Any dogpile on the Dodekatheon has to include them in some way, and since they're also longtime allies of the Elohim, it's inevitable that they're going to get involved.

You might also want to investigate what the native Roman gods are doing and what side they come down on in this conflict. On the one hand, the Dodekatheon in their guise as the Dii Consentes brought massive glory to the empire and are some of the most recognizable members of Roman religion, but on the other hand, they seized control of the pantheon from the native Italian gods who might not have wanted their "generous" help in making their own way. Purely Roman gods like Janus might have an axe to grind, whether by openly siding against them or trying to sabotage them from within, but then again some might support Zeus and his rule and remain staunch defenders of their conglomerate pantheon. There's plenty of opportunity for internecine struggle, back-door dealings and zany avoidance comedy just within the Dodekatheon itself.

As for possible allies for the beleaguered Greeks, don't despair, they have a few. The Yazata might be a surprising source of help; the pantheons have traditionally cooperated fairly well, with Mithra even enjoying a robust Roman cult as Mithras, but they're also tricky thanks to some lingering bad feelings about invasion forces on both sides and the fact that the Dodekatheon have to be on their best behavior around their eastern allies or risk offending them into leaving (or worse, punishing them for their transgressions). They might also be able to call on the Bogovi for aid, who also had quite a bit of friendly overlap and fairly peaceful coexistence with them back in the day.
