Precognition/Alternate Future Display (The Emperor can see countless possible futures at all times, though his ability to act on them is limited due to pinpointing the exact course of events being hearkened by him to wanting to cross an ocean, though having to account for all the possible, innumerable factors that could lead to such an outcome),
Social Influencing (Although aided immensely by his psychic powers, the Emperor is nonetheless an extremely eloquent speaker, a trait inherited by his son Lorgar, which has allowed both of them to pacify hostile worlds without a single shot being fired),
Holy Manipulation (His mere presence is dangerous and destructive upon the servants of the Dark Gods, especially daemons, and his creations such as Living Saints retain this aspect, to a lesser extent),
Life/Death Manipulation (Has shown the capability to bring other being back to life, and should also be capable of outright making people drop dead by manipulating their life energy),
Light Manipulation (The Emperor usually appears as a magnificent giant man of shining radiance, with said light being physical and spiritual in equal parts, and downright destructive to the forces of Chaos),
Paralysis Inducement (If the Emperor so chooses, he can paralyze those with weaker will with his aura alone), Preparation, Invisibility (Should be capable of making himself invisible),
Acausality (Type 4; the Emperor's soul perceives time differently, existing beyond the normal timestream)
Chaos Manipulation(Wielded and shaped the primordial energy from which all was created),
