In many works, there is a God of Evil. An ultimate embodiment of evil that seeks to either spread unhappiness or kill as much as he/she wants.
This is the inverse of that, a deity that seeks to defeat evil and/or seeks to spread goodness. In most works with a God of Good, he/she will often (but not always) be the Big Good, guiding The Hero but not getting directly involved in his/her quest to defeat the Big Bad. In some cases, the god of good's role can be spreading good will or actively repairing that which has been tainted by evil or simply maintaining the world from plain old decay. It might seek to convert all to the setting's standard of goodness, warping hate into love, despair into hope, obsession into indifference where appropriate.
There is a tendency for Gods of Good to be female rather than male. Also, Beauty Equals Goodness (and by proxy Hot God) tends to come into play with this trope. There is common overlap with Gold and White Are Divine and Light Is Good.
Not in any way to be confused with God Is Good, which is when there is a single god who is good (though in most monotheistic faiths, God is given this title, and many others like it, so He actually still counts).
To avoid Flame Bait and Edit Wars, note that this trope isn't about gods who simply are good, it's about gods of goodness. Gods who are nice but mostly defined by other qualities do not qualify. If the god can, by the setting's definition, do evil without contradicting their very being, they don't count.
- Spider Riders has the Spirit Oracle, who is believed to be a goddess by the natives of the Inner World. The Oracle is a very powerful yet kind individual who wishes to protect all life within the Inner World.
- Highfather Izaya, the leader of the New Gods on New Genesis, and opposed to the God of Evil Darkseid.
- The Source is the more literal version of this.
- Marvel Comics has the Vishanti, a triad whose names are Hoggoth, Oshtur and Agamotto, traditionally be the highest "good" deities available for regular consultation. A few polytheistic gods are also this. Balder from The Mighty Thor is the god of light more for his goodness and nobility instead of light powers.
- The Pony POV Series has Celestia and Luna's parents, Fauna Luster and the unnamed Father of Alicorns, both of whom appear to be Anthropomorphic Personifications of existence. In addition, the Father appears to be the Dimension Lord of, and may very well be, Pony Heaven (at the very least, it's contained in His body).
- The Bridge has Big Good Harmony, who is responsible for the creation of Celestia, Luna, and the Elements of Harmony, brought King Caesar to Equestria long ago to fight Tirek and safeguard the newborn Cadence, and has been working to bring about Heel Face Turns in the less evil kaiju. She's also the only one powerful enough to be capable of fighting the Big Bad Bagan on even terms. Though only just barely.
- Arguably the Pyar gods in The Keys Stand Alone: The Soft World. as everything they intended to do when they came to C'hou was the epitome of goodness for someone. They gave the G'heddi'onians a new paradisaical home, the skahs endless monsters to fight, and the tirin and Ketafans a place to live without any monsters to bother them. When they accidentally introduced a great evil into C'hou and were badly weakened by it, they strove to fight that evil by importing outworlders to fight it. However, the Actual Pacifist four are not at all convinced the Pyars are good, given that they turned the world into a giant hunting preserve and imported a lot of truly evil outworlders along with the good ones. But it's all moot, since they're actually in a giant telepathic MMORPG and everything is fake.
- The White Guardian on Doctor Who. A God of Evil called the Black Guardian opposes him, but neither can act in the universe directly, so they work through agents and emissaries.
- Legend of the Seeker: The Creator, who has made all life and light. Unlike in the books, this deity is portrayed as female.
- In Christianity, Islam, Judaism and others, God is often referred to as God of Mercy, God of Love, God of Justice etc. And yes, sometimes God of Good or Goodness. Of course, He's the God of pretty much everything, but these are perhaps His most frequently invoked titles.
- In Islam, the invocation of God (a short phrase used at the start of just about anything—every single prayer, journeys, work, meals), bismi-llāhi r-raḥmāni r-raḥīm, means "In the name of God, most Merciful and Kind", and is quite possibly the single most common phrase any Muslim will utter, regardless of language or nationality.
- In the Bible, the exact nature and origin of evil itself aren't entirely clear, which is a huge source of debate and speculation. Regardless, the Bible tends to describe evil as that which violates God's desires and commands (Judges 2:11, 2 Samuel 12:9, Psalm 5:4-6; 51:4). Although the Bible describes God as a God of good, it does not rule out Him bringing punishment and calamity on the wicked. However, this punishment does often come through people who are wicked, and God is repeatedly shown to be able to "work" various evil actions and events into His plans (being omnipotent and omniscient helps).
- One of the more common Christian ideas is that "Evil" technically isn't a thing, but rather an absence of a thing: the absence of good. God, then, did not create evil because it's not an actual thing, but more of a state. The Genesis account does call God's creation "very good" before the first human sin. Naturally, explanations for the origin of evil tend to involve ideas of free will.
- The Devas of Hinduism; especially Vishnu, the Protector of humanity, who incarnates as Avatars to fight evil when needed. Of Hinduism's deities, one of the most well known is Krishna, who was the ninth Avatar of Vishnu.
- The Bodhisattvas of Buddhism (kind of like Christian saints) are enlightened men and women that refuse Nirvana so that they can save suffering beings by guiding them to enlightenment themselves. The best example of this is Guan Yin, or Avalokiteshvara, the Bodhisattva of Compassion and Mercy who is revered by nearly all Buddhists as the epitome of unconditional love. The reason why she's usually shown with 1,000 arms and multiple heads is to show that she's always wiling to help anyone in need.
- Ra in Egyptian Mythology. While his role was mostly as the sun god, he was pretty much considered the pinacle of morality and "goodness", opposed to Apep/Apophis. Ma'at more so even: she was the personification of moral decency.
- As one of the few gods from Greek Mythology without jerk tendencies (provoked or unprovoked), Prometheus definitely counts. The shit he went through to help us humans is truly amazing.
- Hestia is the goddess of family and all it entails. There may not have been many myths starring her, but she was definitely the most trusted and beloved of all gods. She even gave up her seat on Mount Olympus to make room for a human who had recently ascended to godhood, Dionysus.
- Arete is another example. She's the goddess of virtue and her only real mythological apperance comes from Xenophon's Memorabilia where offers Hercules a life of glory in exchange for hard work. He ultimately decides to follow her path.
- Amaterasu from Japanese Mythology and Shinto is her pantheon's goddess of good, and similar to Ra in Egyptian Mythology she is also a sun goddess. She is described as warm and compassionate, and regularly opposes her Trickster God brother Susanoo. At one point she was so angry and distraught over Susanoo's destruction that she hid in a sacred cave, and all light left the world. She was tricked into leaving by Ama no Uzume, who danced bare naked in front of the cave; the raucuous joyous laughter of all the other gods piqued her curiosity enough that she walked to the mouth of the cave. Ama no Uzume left a mirror facing inwards, and Amaterasu was stunned by the light and beauty of her own reflection long enough for the other gods to coax and beseech her to return to the celestial palace. In the process, Ama no Uzume became goddess of the dawn as well as dance.
- Bai-Ulgan in Turkic mythology is the god of goodness, welfare, abundance, and plentifulness.
- Two of his sons might qualify as well: Karshyt Han and Bakhty Han, the gods of purity and blessing, respectively.
- Zoroastrianism is an ancient religion that holds to a doctrine of an eternal war between the spirits of good and evil. Ahura Mazda is worshipped as the supreme, benevolent spirit, and is forever in conflict with Ahriman, the spirit of evil.
- Dungeons & Dragons has quite a few of these. Strictly speaking, a God of Good must have Good in his or her domain. (A domain is literal or metaphysical field the god has complete mastery of; a God of Fire would have a domain of Fire, etc.) And in 3rd edition, the norm is that every deity who is good in alignment is enough of a God of Good that he or she will grant access to the Good Domain; similarly with all of the gods who are evil in alignment.
- 4E's core pantheon has four of them - Bahamut, Pelor, Avandra and Moradin.
- 3E's core pantheon had Heironeous, Moradin again, Yondalla, Pelor again, Garl Glittergold, Ehlonna, Corellon Larethian and Kord.
- From Dragonlance: Branchala, Habbakuk, Kiri-Jolith, Majere, Mishakal, Paladine, Solinari
- From the Forgotten Realms (and there's quite a list of them!): Chauntea, Lathander, the late Mystra, Selune, Sune, Torm, the late Tyr, Bahamut again, Mielikki, Tymora, Deneir, Eldath, Lliir, Lurue, Milil, and a host of others in other lands of Toril.
- Pathfinder's Golarion, similarly to D&D, has multiple major deities of the Good domain: Cayden Cailean (god of Loveable Rogues), Desna (goddess of explorers), Erastil (god of farmers and hunters), Iomedae (goddess of just warfare), Sarenrae (goddess of the Sun and healing), Shelyn (goddess of beauty and love), and Torag (god of smiths and craftsmen).
- Magic: The Gathering has Avacyn, the goddess who gives hope and protection to the humans of Innistrad against the demons, vampires, and other assorted horrors that inhabit it. She was, in fact, specifically created by the vampire Planeswalker Sorin Markov to serve as the Good in the Balance Between Good and Evil of the plane since the humans were being driven to extinction by everything else, which is a bad thing in the long run since that will lead to the self-destruction of Innistrad.
- Exalted has the Unconquered Sun, who is God of Good because he's defined by four different kinds of Good: being brave, being loving, being determined, and being prudent. His champions are chosen amongst people who possess an abundance of at least one of those Good trait. In fact, the UCS came to be because a titan wanted to be known as Evil Incarnate, and found that no one in Creation was Good enough to contrast him and making that title meaningful.
- Surprisingly, Warhammer has a small number of genuinely good deities. Isha, the Elven mother-goddess of agriculture and life, is constantly described as offering aid to anyone who needs it, which is a lot for being part of a pantheon that is aloof at best. It also helps that one of her avatars is one of the High Elves' co-monarchs, the Everqueen, whose own power can purify daemons, along with being a truly kind and noble individual. For humans there's Shallya who is the Empire's goddess of healing and mercy that requires pacifism for her priestesses who serve as healers and nurses kind of like the Red Cross, especially when they mostly work in keeping Nurgle's diseases at bay, or even cure them miraculously.
- BIONICLE Mata Nui is the Great Spirit and creator of the Matoran Universe, he created the Matoran, the Rahi and even the Makuta.
- Palutena in Kid Icarus. She is the Goddess of Light who swears to protect the humans of the surface world. She is opposed to Medusa, the Goddess of Darkness.
- In the backstory of The Legend of Zelda: Skyward Sword, there's the Goddess Hylia, whom the gods of the Triforce charged with guarding the Triforce from Demon King Demise. Zelda turns out to be her mortal incarnation. Hylia also plays a large role in The Legend of Zelda: Breath of the Wild, where it's revealed that she's basically become Hyrule's patron goddess.
- Final Fantasy:
- From Dissidia: Final Fantasy, Cosmos, the goddess of harmony and the leader of the heroes. This is even more notable for the fact that the series is well known for its portrayal of evil gods.
- Etro of Final Fantasy XIII.
- Ōkami: The player character, as a canine incarnation of Amaterasu.
- In the Mortal Kombat series, Raiden is shown as the leader of the forces of good and the guardian of Earthrealm, until he makes a Heroic Sacrifice in Deadly Alliance and Came Back Wrong in Deception.
- Double Subverted in Fable. The first game has Avo, whose temple the player can make donations to for beneficial gifts. The updated rerelease reveals that "Avo", however, is just a huge mass of Will energy set up by a merchant to scam people. That's the subversion. The "double" part kicks in during game two, in which the Temple of the Light in Oakvale seems to be more or less the same... except the being they worship turns out to be more than just Will energy: it's sentient and can even speak to you depending on your choice of quests. This seems to imply the existence of a higher, benevolent power; even if it isn't Avo.
- Subverted in Der Langrisser. Lushiris is the Goddess of Light and more or less presented as this, but ethically-speaking, she's all too human.
- Blizzard in Primal Rage is literally the God of Good and leads the Virtuous Beasts. He is, however, an Anti-Hero who has no problem with devouring his own followers for strength, and is only "good" because he's fighting against even worse monsters.
- Several deities mentioned in the Religion/Mythology above are included to fight in Smite, most notably Amaterasu and Vishnu in two of his mortal forms: Vamana and Rama, and all three were portrayed as virtuous. On the other hand, while Ra is included, he ends up playing a subversion: While still the God of Good, he was pissed off about that one time Isis poisoned him and make him tell her his real name to gain access of his magic (to defeat Set and free Egypt), so he came off as a Jerkass who seems quite eager to roast his enemies with sun ray.
- The Angels in Nexus Clash are ruled by a trio of Gods of Good: Namm, personification of Justice, Baraas, personification of Cooperation, and Alonai, personification of Love. Since this is a setting where even Gods of Good are flawed, the worlds they shape still fall apart eventually, forcing another cycle of the Eternal Recurrence that drives the series.
- Things Mr. Welch Is No Longer Allowed to Do in an RPG
64. My paladin's battle cry is not "Good for the Good God"
- Gaia, the Big Good of Captain Planet and the Planeteers. She is the spirit of the Earth and the protector of the planet.
- To some extent, Princess Celestia from My Little Pony: Friendship is Magic. While her most explicit role is being the goddess of the sun, one of her roles as stated by the Mayor of Ponyville is being the "Bringer of Harmony".
- The Avatar line, from Avatar: The Last Airbender, is the human form of a divine spirit charged with maintaining the peace between the four nations.
- In The Legend of Korra, Raava, the spirit of light, is also responsible for peace and balance, though her personality can be abrasive and discriminatory. She fuses with Wan to create the first Avatar, meaning that the Avatar is her incarnation on earth to maintain said balance and peace.
- Transformers Cybertron: Primus, Lord of Light and Creator-God of the Transformers, is usually in this role whenever he decides to make an appearance in person. Most of his time is spent in altmode (the planet Cybertron itself).
