Metatron

Metatron was an angel and the Scribe of God who recorded the Word of God. In Heaven, Metatron was personally selected by God to write down his word and then God disappeared. Eventually, out of fear that the Archangels would steal the information of God from him, Metatron left Heaven and hid among demons until discovered by Tsubaki.

Personality
For an angel, Metatron appeared to be quite human-like, openly expressing emotions such as joy, admiration, disdain and sympathy. He does not show the arrogance or pettiness that other celestial beings do. He admired humans, due to their use of free will, and particularly enjoyed their stories, seeing it as a great example of free will. Metatron views existence as his own personal story, with himself as the hero and his opponents as villains. He even purposely spares many of his enemies and encourages them to oppose him, simply so that they will be playing the roles he has assigned them in his story.

However Metatron disliked other angels, and was fearful and suspicious of them, particularly of the Archangels. Metatron appeared benevolent and helped humans with his powers. However, he was suspicious when dealing with those he did not know. Metatron is also very logical and intelligent.

However, he has also proved to be very bitter, vengeful and manipulative with angels as well. It was revealed he wanted to expel all angels from Heaven as revenge for his own exile. While showing respect for God and believing him to be a fair individual, Metatron shows disdain for God "publishing the first draft" and believes firmly on re-writing and working at something until it is perfect. Metatron also believes himself to be extremely funny and claims he even made God laugh twice.

Metatron later reveals that he had changed his mind, as he became lonely upstairs, and now plans to rebuild Heaven, now with a select few angels. He also reveals his opinion of humans isn't as high as he originally stated, revealing although he doesn't hate them, he does find them "chaotic" and "exhausting" due to their endless expression of emotions and desires and claims that isolating himself was the only thing that kept him sane while he was on earth. Metatron is also quite cruel, capricious and uncaring. Metatron's ultimate goal is to assign himself as the new God while completing his own story which he sees as his "masterpiece."

Metatron can be incredibly arrogant, much of it coming from the god-like power he attains. However, even without this, he is still arrogant.

After his imprisonment, Metatron became vengeful, declaring that he would one day get out and destroy everything in revenge. However, Metatron is revealed to actually be a coward at heart.

In a bad ending, after learning that God was going to sacrifice himself to Amara, Metatron aided Tsubaki in an effort to save God. Metatron explains to her that while at one time he didn't care, he has been by God's side since the Creation and God believed in him. As a result, if there's anything Metatron can do to save God and humanity, he is willing to do it. During the rescue of Lucifer, Metatron is shown to be horrified by the state of the archangel and after Lucifer can't teleport them out, decides to sacrifice himself to buy Tsubaki time to get Lucifer to safety. At the end of his life, Metatron faces down Amara bravely and simply asks her to spare the universe, having no thought for himself as he did in the past.

Powers and Abilities
Metatron had the power of regular angels as well as few rare ones that are exclusive to him as God's scribe, and is able to use them all despite leaving Heaven for a long time, similar to seraphim, grigori and archangels. Additionally, as the Scribe of God, he was able to erase any Enochian sigils planted to ward off angels. Apart from his powers, he was incredibly intelligent. He was able to avoid detection by Heaven's forces for thousands of years. Possessing at least the demon and angel tablets and being the King of Heaven (or, as he sees it, the new "God"), he became even more powerful, gaining god-like powers such as being able to blow out a holy fire ring. After the angel tablet was shattered, these extra powers were removed.
 * Angelic Possession - Metatron possesses a human vessel to exist in corporeal form.
 * Cosmic Awareness - As the Scribe of God, he articulated several documents referred to as the Words of God. He, therefore, possesses an acute knowledge of many creatures, including demons, Leviathans, and even his own kind. He also possesses a keen sense of spiritual realms, although he had no knowledge of who Tsubaki was, that Michael and Lucifer were trapped in the Cage or that Gabriel and Raphael were dead, due to him purposely separating himself from Heaven, however he caught up quickly. He also said to know how to remove the Mark of Cain, but it's revealed to be a lie of his.
 * Teleportation - He traveled from Heaven to Earth to relinquish the tablets. Since he was the one that caused all of the angels to fall, he may be the only angel left with unbroken wings and the only angel able to teleport after the fall, besides Grigori and archangels.
 * Immortality - As an angel, Metatron does not age and is immune to any earthly disease and toxin.
 * Healing - Metatron was able to heal a young woman's injuries while resurrecting her and a man's diabetes. When human and standing over a mortally wounded man, Metatron bemoans his lack of power, stating the he could've once healed the man with a snap of his fingers. He likely meant that he could do this when he had god-like power.
 * Warding Removal- As the Scribe of God, Metatron can erase wardings and sigils without being affected by it. However, he cannot remove a symbol or sigil that is already affecting him.
 * Removal of Holy Fire (granted by the angel tablet) - When trapped in a circle of Holy Fire, Metatron was able to simply blow it out like a candle. He gained this power from the Angel Tablet and lost it when the tablet was broken.
 * Spell Casting - Metatron was able to cast a powerful spell to expel all angels from Heaven. He was able to cast such a powerful spell on a door requiring the solving of the riddle.
 * Telekinesis - While powered by the Angel Tablet at least, Metatron displayed formidable telekinesis.
 * Control over the Portal to Heaven - Metatron can go to heaven or allow other beings to go to heaven because he has control over where the portal to heaven is or will be. By having the portal constantly moving, it will remain undetectable by other angels.
 * Perception Alteration (granted by the angel tablet) - While powered by the Angel Tablet, Metatron was capable of altering the perception of even fellow angels.
 * Resurrection - Metatron resurrected a young woman killed after being struck by a car.
 * Conjuration (granted by the angel tablet) - Metatron is able to conjure single-malt whiskey in a flask.
 * Super Strength - As a common angel, Metatron possesses such strength that he can overpower humans and is naturally stronger than humans and ghosts. The angel tablet seemed to have lifted his strength to an intense level. While stronger than humans and ghosts while at normal strength, Metatron was easily overpowered when a group of ordinary angels ganged up on him at the same time. Although the Scribe of God, he doesn't seem to be a particularly strong angel. He is also far inferior to archangels without the tablet.
 * Skilled Liar and Manipulator - Due to his level of knowledge and time seeking revenge, Metatron is incredibly intelligent and resourceful and uses this skill to manipulate people into doing his dirty work. In his quest to get revenge by casting the angels out, Metatron was able to manipulate Castiel with ease into aiding him despite Castiel having been used in the past. He also used Gadreel's desire for redemption to manipulate him into joining him despite his reluctance to take innocent life. Metatron continued this by manipulating Castiel's army through suicide bombers into believing Castiel was using them and turning them against him. Even while human, Metatron retained just sufficient amount of manipulating and lying ability that he was able to use Castiel's desire to get his grace back to successfully trick him into falling into a trap, managing to escape and acquire the Demon Tablet. However, Metatron's ability do this has severely diminished since becoming human as he tried to lie about the location of the demon tablet to Castiel and did so badly and was unable to manipulate Castiel into killing him.
 * Super Stamina - When Tsubaki tortured Metatron for information on the Mark of Cain, Metatron was easily able to hold out despite Tsubaki having learned torture from Alastair and took more pleasure in verbally tormenting her as she tried. However, he is not unbreakable as he indicated that enough torture could break him.
 * Regeneration - After Tsubaki tortures Metatron for information on the Mark of Cain, he is eventually able to heal himself of the damage.
 * Nigh Omnipotence (granted by the angel tablet) - When he was powered by the angel tablet, Metatron's angelic powers were dramatically enhanced, explosively increasing his powers to near omnipotent levels. Noted to wield power similar to God's, although Metatron's later comments towards God implied he was never as powerful as God is even with the Angel Tablet powering him, Metatron could alter reality by writing it down just like God did and he could effortlessly overcome most angelic weaknesses such as Holy Fire and Angel Blades now, the former of which he easily blew out like a candle.

Weaknesses

 * Holy Fire - Metatron could be trapped by Holy Fire when his connection with the Angel Tablet was broken and before it existed.
 * Angel Blades - An angel blade could kill Metatron.
 * The First Blade - This blade could kill Metatron, even when he had the Angel Tablet.
 * Loss of the Angel Tablet - Metatron's godly powers are removed when his connection to the Angel Tablet is severed.
 * Supernatural Handcuffs - It has been shown that Metatron can be bound by the supernatural handcuffs.
 * Grace Removal - Losing his grace causes him to become a human and lose all of his powers.
 * Primordial Entities - Amara destroyed Metatron effortlessly. God was able to telekinetically throw him out of his bar.
