Mastema (Shin Megami Tensei)

Summary
Mastema is a demon from the Shin Megami Tensei series, and one of the Heralds under the command of YHVH. Originating from the apocryphal Book of Jubilees, as well as the Zadokite Fragments and the Dead Sea Scrolls, Mastema is a ruthless, terrifying angel responsible for persecuting evil and testing the piety of man before God, being identified as a bringer of disaster and the father of all evil, and commanding legions of demons to help further his goals, with many of God's more questionable acts in scripture being thus attested to be the work of Mastema acting in his stead. As such, he is widely considered to be another instantiation of the figure of The Accuser that first appeared within the Book of Job.

Attack Potency: Low Complex Multiverse level (An exceptionally high-ranking herald and the leader of Shekinah's armies during the events of Strange Journey, with his power being recognized as incredible by Alex and causing her to promptly step back as soon as she sensed him. Recognized as "an impeding threat" by the Four Cardinal Archangels, while Mastema himself only sees them as troublesome in combination and not individually, going as far as referring to Gabriel as a "rat" who poses no threat to him on her own) | Outerverse level (Exists as an archetype, a shapeless, fundamental unit of the collective unconscious inhabiting the realm of Atziluth, beyond the concept of dimensions entirely, and yet to be shaped into a lower state by the thoughts and emotions of humanity)

Notable Attacks/Techniques:

More detailed information on this character's skill list can be found in the Megami Tensei wiki

Buffs and Debuffs: A set of skills that, as the name implies, allows the caster to greatly amplify their own physical attributes and reduce that of their foes, thus allowing one to stand up to much stronger opponents by closing or even reversing the gap in power between them. Outside of gameplay limitations, they can be stacked indefinitely, and sufficient usages of buffs allow the caster to survive attacks that would otherwise obliterate them with only minor injuries and amplify their speed to the point of completely outspeeding opponents that could previously predict all of their movements, while debuffs have a directly proportional effect on the enemy's statistics.

Almighty Attacks: The highest class of spells in the Megami Tensei franchise, consisting largely of powerful non-elemental attacks that have the special property of completely bypassing any resistances or immunities that a target may possess, be them innate or magically enforced, the latter of which including anything from reflective barriers to items that distort the very laws of the universe in order to protect the user from all forms of damage, and they are likewise unable to blocked, drained or generally defended against.
 * Megidolaon: Unleashes a wave of destructive energy which deals heavy damage to all foes, tapping into the pale light of divinity that reigns over destruction itself and engulfing them in "the complete annihilation beyond death."
