The decision of Breveros was what Nightwing was waiting for.
He needed Breveros to make the decisive decision and request to remove the curse so he could again go through the agonizing process and resist it.
Nightwing used many schemes and poured the power of Mysterion and Tyrannos into the soul of Breveros.
Mysterion was the force that Destiny fought against, for it attempted to cover and hide Breveros. Tyrannos was to give Breveros the rebellious spirit of defiance and wrath.
True enough, Breveros fell into uncontrollable rage and anger the past days.
He was bipolar and would remember the embarrassing moments that limited him.
He even suspected that perhaps his brother and father were behind the sabotage of his illustrious would-be career.
The cultivator and fighter within him were awakened. The power of Tyrannos did not change him but heightened his pride of his. He found out he had potential and was failing at it!
