Physical strength: Metaverse level (with his attacks, Spem metus sepuitur, Disce Libens, he destroyed infinite universes. Was able to create a cross of stars spanning the entire multiverse and tank attacks from Reinhard in his Atziluth)
Attack potency/Destructive capacity: Star level (Stopped a Longinus attack from a bloodlusted Reinhard) || Metaverse+ (A hegemony god with a Taikyoku of 90 making him one of the strongest in the series. A Hegemony god with 1 Taikyoku considers the Throne but a tool for the projection of his Atziluth.

Noteworthy Techniques and Abilities
- Vive Memor Mortis - Acta Est Fabula: (Live Mindful of Death - The Play is Over) The manifestation of Mercurius’ Law, “To experience the unknown, dying in the arms of Marie. Absolutely any other end than that, is unacceptable”. When his Law is activated at the time of his death, Mercurius will reset everything if it does not end how he wants it to end, even in realms where time is nonexistent such as the Throne. While everything is resetting, Mercurius is able to change the next timeline in whatever way he likes (Such as erasing any factors leading to Hajun’s rise after the events of Marie’s route) and this power even allows him to bring back the Throne itself (a place where no form of time exists) after it is destroyed (ex. his fight against Reinhard) and those whose entire existences were wiped out completely with no chance of recovery (as this was able to bring back Ren, Reinhard, and Marie after they died and won fighting against Hajun), albeit the butterfly effect that his changes produce is out of his control. All abilities described below are mere side-effects of his Law.
- Sequere Naturam: (You Are to Follow Nature) Mercurius unleashes a Supernovae that consists of thousands upon thousands of stars condensed into a single blast that can atomize Gods from the inside. This move was also powerful enough to have been able to instantly kill Nerose Satanel, a Hadou God equal in power to the likes of Ren and Reinhard during Marie's Route, in one hit.
- Dura Lex Sed Lex: (The Law is Harsh But It Is Law) Mercurius creates a Great Attractor which draws everything towards it into a singularity.
- Aurea Mediocritas: (The Golden Mean) Mercurius aligns the stars into a Grand Cross, causing an astrological energy surge that can incinerate Atziluth Gods from inside-out.
- Omnia Fert Aetas: (Time Robs Us of All) Mercurius makes all of existence into an elementary particle and sends it into the past of the opponent, thus causing a paradox and erasing them from existence.
- Disce Libens: (Learn Eagerly) Mercurius condenses all the stars in the multiverse into a black hole that destroys everything. This causes everything in existence to be erased completely, including the Throne itself.
