Likely caused the "Storm of the Emperor's Wrath", a massive Warp storm which wiped out an entire sector of the galaxy). Psychic powers, soul destruction, and Warp-based attacks ignore durability. | At least Complex Multiverse level, possibly Low Hyperverse level (Able to hold off the four Chaos Gods from breaking into realspace)
Speed: At least FTL+ movement speed (Far faster than his Primarchs, Horus, the strongest Primarch, could not follow his father's movement with his eyes), Massively FTL+ reactions/close combat speed (Fought the C'Tan Void Dragon on equal footing and punched it from Earth straight to Mars. A space marine who gained a small portion of his power viewed everything as being completely frozen when he moved). Much faster with time manipulation/time stop. | Likely Omnipresent

Standard Equipment: Highly customized and augmented Terminator armor, customized personal Bolter gun, power blade, and flame sword (Pre-Horus Heresy)
Intelligence: A massive genius on the scale of technical, mechanical, in general basically everything such as genetics and biotechnology that allowed him to research, design and develop the Primarchs, Custodians, and Astartes, and make each such incredibly powerful and durable warriors; nearly undid the influence and power of the Immaterium/Warp and its Patron Gods of the Chaos Pantheon with his intelligence leading to great devices, developed the Astronomican; lead thousand upon thousands of fleets, flotillas, armies, and armadas across most of the galaxy in a period of just over two hundred years; is a master strategist and tactician of the highest order and supremely qualified diplomat and leader in all things considered; a super genius and charismatic man if there ever was one
Weaknesses: Faced with dealing with close friends or "sons" makes him not use his full power outright unless absolutely necessary, the Golden Throne's life support system begins to fail as it will be a matter of time before he dies if there is no solution, and if that happens, the results are completely unknown.
-Warp Storm: By disrupting the Warp, he can create devastating Warp Storms capable of turning space itself into chaotic turbulence, destroying star systems, and more.
Key: In the Materium | In the Warp
Note: The first set of stats are for the Emperor in his prime during the Great Crusade, before he was crippled by Horus and barely kept alive by the Golden Throne.
Note 2: The Warp storm named "Storm of the Emperor's Wrath" is not yet proven conclusively to be the Emperor's i.e. a massive multi star system encompassing psychic/warp storm after the Heresy (post 31st century) is likened to be the Corpse's God's power, but this is the claim of the clergy of the Imperial Church, thus it's not entirely conclusive if he actually did it.
