Having decided to rebel against Zeus, the king of the gods, there were many mountains to overcome.
First of all, realistically, Zeus is incredibly strong.
If Poseidon and I join forces, we might win, but no one can defeat Zeus alone.
The numerous forces of the underworld would be of no help in the battle against the three main gods, so I must find another way.
Should I negotiate with Gaia and seek her assistance?
...
No. Surely she would demand the release of the Titan gods trapped in Tartarus.
No matter how eloquently I speak, I would have to concede to release the other Titans, except for Cronus.
If countless Titans were freed, I would not be able to control them with my own power.
Yet, I cannot rely on Poseidon, who is always eyeing Zeus's position.
To take the throne of the king of the gods and change Olympus, I must subdue all three main gods, excluding myself.
Even if I manage to drive Zeus out, if a conflict arises with Poseidon over the divine status of the heavens, mortals would continue to suffer from the ongoing battles for decades.
It might be more likely to use him and then stab him in the back, but... he certainly wouldn’t go down without a fight.
