"Hear the cries for revenge thunder across the sky! I can feel the wrath!"
- Ah! My Goddess had Hild, the CEO of Hell. She's the mother to Belldandy's half-sister Urd. Their father is God.
- An important part of the plot of Angel Sanctuary is the attempts by high demons to resurrect Lucifer. His generals are called the Satans and all bear names such as Asmodeus, Belial, Astaroth etc. Lucifer himself is actually on the good side, in the end—although he does do a lot of crap.
- The manga version of Bastard!! (1988) eventually brings in Christian cosmology, with angels, devils, etc. The main character, Dark Schneider, has been known to fight against both. Satan himself makes a major appearance, and is hinted at being the eventual Big Bad. Interestingly, Satan and Lucifer are two separate beings in the story.
- In Beelzebub, Satan and Lucifer are two distinctly different beings (Satan's appearance being depicted as that of a young male, Lucifer's being that of a little girl), but are part of the same group of demons—the Seven Sin Lords, who were the rulers of distinct kingdoms in the Demon World before it was united under Baby Beel's father, the Demon King aka Beelzebub III. Beel is also part of this group, being the latest demon to inherit the name "Beelzebub." Both Satan and Lucifer are contracted to the two strongest members of the Ishiyama Upstarts, Fuji and Takamiya, in opposition of Oga and Beel, with the entire conflict risking the possibility of a new war erupting in the Demon World. While Takamiya has been defeated and allied with Oga, Fuji has proven himself to be uncontrollable and a dangerous threat, causing an Enemy Mine with the entire school standing against him as he begins petrifying everyone.
- Satan himself appears a few times in Blue Exorcist, always while possessing someone (he's far too powerful to manifest in the human realm). He's a complete Jerkass who swears like no tomorrow and kills random people just for the hell of it, laughing all the while. Near the end of the series, the reason for his hatred against humans is revealed: he was completely ignorant to many things including the very concept of mortality until he encountered a Plucky Girl who not only didn't fear him but was immune to his flames and willingly invited him to possess her body, saying that he must be lonely to have everything he touch burn to ashes. Over the next year, she explained to him the concept of life. When Satan stated he wanted to live, Yuri's response was that life cannot be taken or given, only created. You know the result... Naturally, the Church freaked out big time and tried to burn her at the stake before she gives birth, dismissing her claims that demons are Mirroring Factions as blasphemy. Cue Satan possessing every powerful exorcist he could reach to find a host body he could save her with, ultimately succeeding but not without killing hundreds in the process. Yuri died from childbirth and Satan swore to take revenge by merging the human and demon worlds into one. Love Makes You Crazy, much? Too bad the next person he possessed and had Driven to Suicide was Fujimoto, the very same man who went against orders to raise Satan's sons in secrecy; Rin, one of said sons, promptly decided to kick daddy's ass. Should be noted that everything in the spoilers is an anime-only thing. So far, the manga hasn't come clear with his true goal and motives. Rin still wants to kick his ass though.
- While he's never made a direct appearance, Lucifer is mentioned in A Certain Magical Index several times by members of the Roman Catholic Church when discussing the Archangels. In the Index-verse, where angels have no free will of their own and that they are meant to be God's perfect tools, and are often referred as messengers of God to humanity, Lucifer and his Fallen Angel brethren are notable for "malfunctioning" and gaining wills of their own, which caused their rebellion against God and ultimately being cast down by Archangel Michael. It's noted that before this Lucifer had the unique position as "The Right Seat of God," which paradoxically made him God's equal despite being an angel and serves as part of the inspiration for Fiamma of God's Right Seat's goal to become La Persona Superiore a Dio (The One Above God).
- In Devilman Ryo Asuka is revealed to be Satan as well as a Hermaphrodite with angel wings. Nagai considering it appropriate due to being an angel, who are often considered sexless.
- Although not Satan himself, his second in command, the Demon Lord Zennon
◊ has a similar appearance to Satan in The Divine Comedy, being a demon with 3 faces, first appearing in the manga frozen in a block of ice, while in Devilman Lady he happens to be contained in the Ninth Circle of Hell. In Violence Jack, Satan has him transform into a dragon for use in the final battle against Devilman, which could be seen as an allusion to The Beast of the Revelation.
- Although not Satan himself, his second in command, the Demon Lord Zennon
- Father from Fullmetal Alchemist is the original homunculus, but he comes from the Gate of Truth, which is the franchise's equivalent of Heaven, and his backstory is much more in line with Lucifer, making him this.
- In Mobile Fighter G Gundam there's the Devil Gundam. At first it doesn't seem all that demonic, but as the series progresses and the machine is shown to have a will of its own, a vendetta against mankind, a tendency to corrupt everyone it comes in contact with, and at the grand finale is said to run off of negative emotions, it becomes a lot more obvious.
- The Spider in Hell Girl may or may not be the devil. If not, then it's a simple case of Everybody Hates Hades.
- In Lets Bible, Iesu (pantsless girl Jesus) is menaced by Evil Mexican Mariachi Satan.
- In My Balls, Satan is a female nymphomaniac and sex expert who has both the power of light and darkness in her. She later hooks up with Michael and becomes an angel again.
- O-Parts Hunter: Main character Jio has Satan sealed up inside him.
- Although never making a direct appearance, Satan is a big part of Phantom Thief Jeanne. It turns out that Maron is actually working for Satan and not God when she collects the demons in paintings. She finds out too late to prevent Satan's overthrow of Heaven. Or so it seems...
- It seems that in Princess Lucia, Satan lost his place in Hell and owns a ramen stand.
- Saint Seiya. Lucifer is the Big Bad of fourth (non-canon) movie.

Because of this, he developed pride and lust for domination upon all of creation, and declared war on its Creator. He was subsequently defeated, and then banished from heaven along with his followers. He is defeated also by the archangel Gabriel, helped by Athena and the eastern god Marishitien. He feels a grudge against Athena and allies with other Gods for kill her and take over the world.
- In the "Black Dragon King" arc of Space Adventure Cobra, Evil is a giant and demonic Fetus Terrible who casts horrible illusions to feed off the fear of people and turns his victims into soulless abominations.

- In The Demon Ororon, Hell is a dimension ruled by kings who pass down the title of Satan from father to son. Which, if any, is THE Satan is unknown.
- That Time I Got Reincarnated as a Slime: He doesn't appear specifically, but his name and two best-known alias are tied to the Sin Series Ultimate Skills: Prideful King Lucifer, Wrathful King Satan, and Gluttonous King Beelzebub, all owned by the True Demon Lords Guy Crimson (the first Demon Lord and most powerful Primordial Demon who is a self-proclaimed Evil Overlord), Milim Nava (the second Demon Lord and daughter of True Dragon Veldanava), and Rimuru Tempest(the most recent Demon Lord who eventually becomes a True Dragon himself). Rather fittingly, they are the three strongest True Demon Lords in existence.
- In Umineko: When They Cry, Satan is the third eldest sister of the Stakes of Purgatory and represents the sin of Wrath. She is described as being Tsundere without the dere. Hell, all seven could count, since they're all named after the horned one. There's also Lucifer (Pride), Leviathan (Envy), Belpehegor (Sloth), Mammon (Greed), Beelzebub (Gluttony) and Asmodeus (Lust), in order of how old they are.
