After the first clash between Prince Poseidon and the Tower of Sukkot, Sebastian became sure that this was not a battle that could be won alone.
Even before the first clash, when he associated the identity of this self-proclaimed Atlantian Prince with the Chosen Athena that he saw some time ago, he was alarmed and was prompted to make countermeasures.
From the raw strength that was displayed by the Prince, Sebastian was sure that in a one-on-one battle, he would be pounded to bits in seconds.
Sebastian could afford to lose his Leviathon body since all he needed to recreate it was to expend a bit of mana, but the uncertainty that was associated with this Chosen was what left him apprehensive.
As was already shown through the Domain World, against Black tier strength, his advantage of living doppelgangers was not as OP as he thought.
