Uriel.

Uriel can be considered the brightest and most positive character in the entire series—he is merciful, benevolent, and sympathetic. Among the entire host of Heavenly Forces, it was Uriel who decided to descend to Earth to help people, likely because he is revered as the patron of science and related research. However, his kindheartedness worked against him, allowing Dr. Ernsman to deceive the Angel and turn him into a living battery. Despite all the suffering humans subjected Uriel to, he did not change his attitude toward humanity and tried to warn them that their sins had poisoned this world, allowing Lucifer to come to Earth. The Angel is also aware of Satan's plans to cause a global nuclear war, and he attempts to convey the threat the fallen angel poses to humanity through distorted television broadcasts and the transmission of his messages. Uriel actively assists the Traveler, helping him reach the Holy Land and warning him of the dangers that await him. However, he understands the depths of human wickedness, so he offers the Traveler a generous reward for saving him. Although Uriel is kind to humans, he doesn't actively engage with his tormentors, only begging them to release him. Nevertheless, Ernsman notes that the Angel possesses an extremely high level of intelligence.

It's clear that Uriel, as befits an angel, loves God and mentions Him as a kind protector. For example, before Lucifer's public debut, Uriel says that He, referring to the Lord, will protect the Traveler from the Devil's influence.

Uriel, being an Archangel, has vast supernatural powers: in particular, he is able to heal and even resurrect people. According to Dr. Ernsman, his capabilities are almost limitless - the use of angelic energy allowed people to overcome the energy crisis on Earth.

Uriel is also a telepath, capable of broadcasting over vast distances and distorting recordings and television broadcasts.

Uriel is first mentioned (and perhaps even appears directly) in the very first episode, where Satan (or the angel himself, quoting Satan) provides a brief background story—the pollution of Earth and the moral decline of humanity, the arrival of the Archangel, and his capture. The latter was, among other things, the ultimate act of sacrilege and desecration of the Heavenly Powers, marking the final degradation of humanity and paving the way for Lucifer to come to Earth.

A more complete appearance occurs in the episode "Listen to Me," in which Uriel, trapped in the generator's cage, attempts to convey to the viewer, presumably the Traveler, the information that Lucifer is already on Earth and that the world is soon facing nuclear war. Soon, a broadcast from the US President announces a coming world war, confirming Uriel's words. Uriel appears indirectly in the episode "How to Survive in the Holy Land," instructing the Traveler on the threats they will face on their way to the generator. He warns of the dangers posed by hunger, thirst, and the Forgotten, and also warns the Traveler against looking to the sky, as Lucifer will do everything to hinder them. When Satan appears behind the hero, the Angel does everything to protect him, warning him not to listen to the Devil's words, as he has come with only one goal: to destroy the world.

Uriel appears in the episode "Boots" during Lucifer's reading of the poem of the same name. Here, he appears merely as part of a general vision created by the Devil to intimidate the Traveler. Uriel's most recent appearance is in the episode of the same name, where Angel's name is revealed. Dr. Ernstman explains that Angel possesses immense intelligence, but rarely communicates. At this point, the creature begs the doctor to release it, but he refuses. He then speaks of the possibilities that open up to humanity through the use of angelic energy. Specifically, he says that Angel can heal.

As in original Christian theology, Uriel belonged to the Eight Archangels who remained faithful to the Lord after Lucifer's rebellion. He first appears in person in the Book of Ezra, where, through similes and allegories, he explains to Ezra the unknowability of God, and also reveals the imminent arrival of the Savior and the sinfulness of the world.

Uriel descended to Earth when humanity, having destroyed almost the entire biosphere, cried out to God to grant them His mercy. However, this was all part of Lucifer's plan, according to which human scientists, led by Dr. Ernstman, were to imprison God's messenger within a special generator powered by his energy. And so it came to pass: Uriel was deceived and captured by humans, becoming the source of an infernal machine. The generator, containing the Angel, was placed in a laboratory located in a place known as the Holy Land. By Lucifer's will, the Holy Land was overrun by the Forgotten—grotesque monsters who guarded the place.

Uriel, also known as Angel, is the main character and titular protagonist of the animated horror series Angel Engine. He is a messenger of God who descended from Heaven at the request of humanity to help them save the planet. As part of Lucifer's plan, he was captured by Dr. Ernstman and transformed into an energy source.

Uriel is considered the patron of science and scientists, and he likely came to Earth to help humans save their planet through scientific research. However, his own sphere of patronage was ultimately turned against him.

An Angel of God, not of human beauty—that's precisely what Uriel was like when he descended among humanity. He had long, blond hair and eyes the color of the early sky. He wore a long, white robe, like an angel's. Large, powerful wings adorned his back, and a halo gleamed on his head, lit by the light of the early sun. He was quite tall, and his build was strong yet slender.
