The Eyes of Fate is an ocular kinetic that's linked to Hydama Bolt's Fatumkinesis.
The Eyes of Fate is linked to Hydama's innate kinetic, Fatumkinesis. The Eyes of Fate has been stated by Dr. Goppo to control the balance of kinetic energy that allows Fatumkinesis to be controlled properly.
History
The Eyes of Fate hasn't been awakened in six-hundred fifty one years and the previous wielder of said eyes has been stated to be "the strongest exorcist ever."
Usage
When used by Hydama, he's shown to have been able to create a barrier from a point blank attack and destroy an area created by Dr. Goppo's kinetic energy.
Revival Fate: Green
As explained in Chapter 12, "Revival Fate: Green" is the default form the eyes take and will automatically activate if deemed necessary. Revival Fate: Green can also completely heal Hydama as shown in Chapter 18 when half his body was blown up and was healed completely as if it didn't happen.
Myth confirmed that in Chapters 1-3 that is was in Revival Fate: Green; however, didn't color it because at the time of their production he didn't color it in.
Sacrificial Fate: Red
As explained in Chapter 12, "Sacrificial Fate: Red" the form the eyes take when Hydama's mindset changes to "just keep fighting." This form trades in all sense to survive in exchange for strength.
Tranquil Fate: Blue
As explained in Chapter 42, "Tranquil Fate: Blue" the form the eyes take when Hydama's mindset changes to that of reaching the core maximizing kinetic energy efficiency, that being tranquility. This form trades Hydama's active consciousness for maximum efficiency in his attack and movements. He fights sub-consciously and is confirmed to not be as much of a direct strength increase as the other two previously shown colors.
