Alter Ego's weaponization

Cain felt the power of the Alter-Ego, the gargantuan beast the size of a city capable of setting the sky ablaze. The massive serpentine creature could fight on its own, and its power would be nothing short of extraordinary, matching half of the strength he could unleash with his body and Laws.

Of course, it took nearly every iota of Ego Wave to materialize such a gargantuan creature in the real world. The most practical use of the Alter-Ego's power would be to keep it inside the Soul Dimension, the realm within Cain's brain, where it would increase his mental and spiritual defenses even more. 

When inside the Soul Dimension, the Alter-Ego's power could run through Cain's body and energy. It was better to have an extremely powerful entity than two average ones. 

Cain stared at the Alter-Ego with a smile. It carried a sense of immense purity and warmth that could help people rise and grow stronger.
