Rundown of his powers in comments

List of Omega Blook's powers:

Fire manipulation
Ice manipulation
Electricity manipulation
Ability to cut off/mess with power in a confined area
Psychic capabilities (Very intense but controllable)
Note: All powers taken from other Blooks are more powerful, just to prove he's the best one.
The ability to delete something/someone (Ignored)
The ability to create and destroy Shadows (Ignored)

War creator
(His magister combined with omega alloy with the emperor-sword makes Omega Blook look like a baby)

Magisteel*
