I think it could be really interesting. Maybe the 'oc' (original character) has some unique powers as the son of chaos. He might use these powers to overcome various challenges in saving Olympus, like fighting against powerful Titans or dealing with internal disputes among the Olympian gods.
A plot twist might be that the oc has to team up with his enemies in the chaos realm to save Olympus. Or perhaps, when he saves Olympus, he accidentally unleashes another greater danger because of his chaotic powers. Maybe the gods who he saves end up betraying him because they fear his power as the son of chaos.
Since it's a fanfic, the possibilities are endless. 'Chaos saves olympus fanfic' might explore a world where the traditional order in Olympus has been disrupted. Chaos could be a misunderstood entity that actually has the ability to restore balance. It could be a story full of twists and turns, with chaos making alliances with certain gods or creatures in Olympus to fight a common enemy. For example, chaos might team up with Hermes, known for his speed and trickery, to gather information and defeat a powerful foe that is endangering Olympus.
In this fanfic, Chaos is surely one of the main characters. As for the others, it could include Athena, the goddess of wisdom. She might play a crucial role in devising plans to cooperate with Chaos to save Olympus. There could also be a centaur or a nymph that has some special knowledge or ability that aids in the whole process. Another possible main character could be Apollo, with his powers of light and prophecy being useful in the fight against the threats to Olympus.
Many 'Percy Saves Olympus' fanfictions also explore the theme of the clash between the modern world and the world of Greek mythology. Percy, being a modern - day demigod, has to navigate both worlds, and this creates interesting scenarios. For instance, he might use modern technology to defeat ancient monsters while saving Olympus.
I'm not entirely sure as it could be about many things. It might be a fan - created story where Percy is portrayed as the son of Chaos. Maybe it involves Percy having special powers or going on unique adventures because of his relation to Chaos.
A new and powerful Titan who has been hiding and gathering strength all this time. He could be jealous of the Olympians' power and wants to take over. Percy would have to figure out his weaknesses and stop him before he causes too much destruction.
Well, 'twd' might refer to 'The Walking Dead'. 'Saves' could imply that something in the context of 'The Walking Dead' is rescuing or preserving. 'Group' might be a specific group within the 'The Walking Dead' universe. And 'oc fanfic' stands for original character fan fiction. So it could be about a story in 'The Walking Dead' fanfic where a group is saved and involves original characters.
A really cool plot twist could be Percy finding out he has a long - lost sibling who is on the side of the Titans. This would create a huge internal conflict for Percy as he has to decide between his loyalty to his new - found family and his duty to the Olympians. It would also add a lot of drama and tension to the story as he tries to sway his sibling to the right side.
One idea could be Percy going on a quest to find a lost artifact that has the power to restore a dying part of the godly realm. This would involve him facing new monsters and making unexpected alliances.
