༺༒ Michael and Lucifer༒༻

He is portrayed as the ruler of all creation, deeply revered and loved by angels. He is considered the sole progenitor of the Morningstar family.
Some key details from the article:
He is infinitely powerful: his boundless imagination gave birth to the cosmos and the Heavens.
He is a slender creature with pure white skin, pearly white teeth and four floating eyes around his head.
He wears a white suit with gold accents, a large top hat with a gold cross, shoulder pads with angel wings, dark gray gloves, and shoes with gold toes. His long cape is a dull blue with white edges, and on the inside is a moving blue galaxy.
His personality is reminiscent of a children's TV show host: he encourages virtues and imparts life lessons, but he can also be a capricious dreamer who wants his creations to love the world they've created. However, he has a habit of swearing frequently.
He possesses unfathomable powers: he is able to create nearly omnipotent entities from nothing and construct entire planes of existence.
God has two sons closest to him: Michael and Lucifer. And despite the fact that he previously sent Lucifer to Hell and now brought him back, he loves him more than his brother. Currently, God is also unaware that he has a niece named Charlie.

An archangel who was created after Michael, who is his brother. Lucifer was once banished to Hell, but now God has finally returned him. However, in Hell, Lucifer had a daughter, Charlie, who remained in Hell because she is a demon.
Lucifer doesn't do much; he's just a sweet, silly archangel who's crazy about rubber duckies. He has the same outfit as Michael, but instead of blue, his clothing has gold details and a gold hatband. Lucifer has pale, almost white skin, like his brother. He has a slender build and hair the same color as Michael, but shorter. Lucifer also has red eyes.
God, as it has already turned out, loves Lucifer more than his older brother, Michael, but Lucifer himself does not notice this, being too soft.

Michael is an archangel, the first of the archangels created by God. He is
Commander-in-Chief of the heavenly armies and five other archangels, a legendary warrior and the greatest of God's angels.
Leader of the Seven Heavenly Virtues, the Archangel of Humility, who has the closest divine connection with God and acts as His sword and shield.
Lucifer's twin brother (fraternal, not identical twins), and also the uncle of Lucifer's daughter, Charlie.
Role in the plot
Mikhail leads an army of exorcists who descend into Hell annually to conduct purges—exterminating demons and preventing their rebellion, as well as controlling overpopulation. He is merciless toward demons, refusing to see them as anything other than the embodiment of evil and sincerely believing them incapable of redemption.
Michael is portrayed as a confident, compassionate, and virtuous archangel, possessing the qualities of a valiant crusader. Outside of battle, he is more carefree, but in the heat of conflict, he becomes serious, dogmatic, and displays a cold determination.
In appearance, he is a slender angel with pale skin, light hair with light coral highlights, and blue eyes. He wears a luxurious white suit with blue details and a white hat with a blue ribbon (the shape of a magician's hat, for example).
As an archangel, Michael possesses colossal power:
Immortality and almost invulnerability (only God can kill him).
Michael also has huge white wings for flight and protection, and masterful swordsmanship and hand-to-hand combat skills.
Creation of portals between dimensions (Heaven, Hell, Earth).
However, despite all of Michael's qualities, God loves his younger brother, Lucifer, more. This deeply hurts the archangel, but he doesn't speak of it, preferring to pretend that he doesn't notice the greater love for his brother from his father (God).
