Theron had been expecting a few things; to be met with resistance, to walk right into the trap of the Sea God. The God was unconscious after all. However, the War General wasn't expecting and had never expected that his venture to the Sea King would be so easy.
The moment Theron entered into the pool of water that made up the internals of the Sea monster, he went for the body of the God at a pace that split the waters apart. Then he made a decision. With his body as the conduit, he summoned a bolt of lightning from the skies. It descended with fury, drenching his entire body in its blinding radiance. And for a moment, Theron looked more like a Lightning Deity than Zeus had ever been.
