The ''VideoGame/{{Ultima}}'' series starred a consistent recurring cast, especially from ''VideoGame/UltimaIV'' onwards.
!!The Avatar (originally: the Stranger from another world)
The [[CharacterCustomization customizable]] [[PlayerCharacter protagonist]] of all ''Ultima'' games from ''I'' to ''IX''. Although most games allow the player to select the Avatar's gender, in those that don't, he is male.

%%* AnAdventurerIsYou
%%* AllLovingHero
* AntiHero: He becomes this in ''Ultima VIII'' where is forced to do questionable things in order to go back to Britannia from Pagan.
* BadassInDistress: At the beginning of ''Ultima VI'', the Avatar is captured by the Gargoyles and is about to be sacrificed.
* BadassNormal: Technically, he is a regular human from Earth.
%%* {{Determinator}}
* DudeWheresMyRespect: Seems to be often mocked or treated badly by some [=NPCs=] throughout the series despite being the supreme hero of Britannia.
* FeaturelessProtagonist: Most games allow the player to customize the Stranger/Avatar, under the assumption that the players basically play themselves in the games.
* AGodAmI: At the end of ''Ultima VIII'' after defeating the Titans by acquiring their powers.
%%* GoodIsNotNice
%%* GuileHero
* HairOfGoldHeartOfGold: Since the games' graphics got to be good enough to display such detail, he's almost always been portrayed as a blonde.
%%* TheHero
%%* HeroicMime
%%* HeroWithBadPublicity: In ''Ultima V''.
%%* IdiotHero: In ''Ultima IX''.
* IncorruptiblePurePureness: What being the Avatar is ''supposed'' to entail, though in the games themselves, it doesn't always work out.
* HeroicSacrifice: [[spoiler:At the end of ''Ultima IX'', to destroy the Guardian.]]
* KnightInShiningArmor: Depending on the class of course.
%%* MagicKnight
* MagikarpPower: If you opt to play as a Shepherd in ''Ultima IV'', you obviously start off very weak and will rely on your companions to get you through the game, but in the process of becoming the Avatar, your weaknesses effectively end as you gain access to all equipment and magic, leaving your party without TheLoad to worry about.
%%* MemeticBadass: In-universe.
* MikeNelsonDestroyerOfWorlds: In undertaking the quest of the Avatar in ''Ultima IV'', he unwittingly brings about the destruction of the Gargoyles' realm, resulting in the events of ''Ultima VI''. Later on in ''Ultima IX'' he all but finishes them off, albeit while working under the instructions of their self-appointed leader.
%%* LivingLegend
* TheParagon: The whole point of being the Avatar is to be the paragon of the Eight Virtues to the people of Britannia..
* TookALevelInDumbass: In an attempt to simplify things for newcomers in ''Ultima IX'', the Avatar infamously seems to have forgotten how Britannia, and just about anything else for that matter, works. Including having a book that goes on about how reading books is so much fun, and [[MemeticMutation asking what's a paladin.]] The game even seemingly does a LampshadeHanging by listing your starting Intelligence stat as "Dim".
* SuddenlyVoiced: After spending most of the series voiceless (due to limited technology), the Avatar first acquired a voice in ''Ultima IX''.
* WeAreAsMayflies: Humans from Earth age much more slowly in the world of Sosaria. This technically applies whenever he's there.

!!The Companions of the Avatar
Traditionally, eight individuals who joined the Stranger on the [[VideoGame/UltimaIV quest to Avatarhood]] and each [[EmbodimentOfVirtue embody one of the Eight Virtues]] are considered the TrueCompanions of the Avatar, although he was joined by others in the course of later adventures. Three of the eight (Iolo, Shamino, and Dupre) encountered and helped the Stranger even before that.

!!!Iolo [=FitzOwen=]
A famous bard and a skillful crossbowman, Iolo is one of the mainstays in the ''Ultima'' series (alongside the Avatar and Lord British), being present in some form in every game except ''[[VideoGame/UltimaVIII Pagan]]''. He is married to Gwenno and owns a talking horse named Smith, who usually appear alongside him. Iolo embodies the Virtue of Compassion.

* BadassGrandpa: He appears physically the oldest of all the companions, his hair and beard graying in ''VI'' and shock white in ''VII''. This doesn't hamper his skill with the crossbow any, and he can still fight alongside the Avatar just as well as any of the other companions.
* CamelCase: His last name.
* DemonicPossession: By the Bane of Insanity in ''[[VideoGame/UltimaVIIPartII Serpent Isle]]''.
* GadgeteerGenius: He invented triple-shot crossbows.
* HappilyMarried: With Gwenno.
* JackOfAllStats: Balanced in strength and magic capability, with a proficiency in dexterity.
* QuirkyBard: [[AvertedTrope Averted]], as he (along with the rest of the Bard class) is a competent fighter with high dexterity, as well as balanced strength and magical capability, though this is mainly because [[CallAHitPointASmeerp "Bard" stands for]] [[FighterMageThief thief/rogue]] in the post-''Ultima IV''-speak (because an Avatar of the Virtues couldn't well have a likely criminal in his party--even less be one himself).
* SapientSteed: His horse Smith, though we never see anybody riding him.
* StickyFingers: [[CharacterizationMarchesOn Had a tendency]] [[EarlyInstallmentWeirdness to pilfer your things]] in ''VideoGame/UltimaI''.
* TagalongChronicler: Goes on adventures with the Avatar and sings about them later.
* WanderingMinstrel: Whenever he is not saving the world, he travels around Britannia composing and performing songs.
* WeAreAsMayflies: Humans from Earth age much more slowly in the world of Sosaria.

!!!Shamino Sallé Dacil
A king of one of the old Sosarian realms and a friend of Lord British, Shamino becomes trapped in Britannia after [[VideoGame/UltimaI Mondain is defeated]] and his home continent is lost. From then on, Shamino becomes a [[ForestRanger ranger]] and embodies the Virtue of Spirituality.

* AuthorAvatar: Though it's much less well-known than the case with Lord British, Shamino is based off of the persona Richard Garriot used in the Society for Creative Anachronism.
* [[SleptThroughTheApocalypse Away During the Apocalypse]]: Happened to be visiting Lord British when the land he ruled [[RetGone suddenly disappeared]].
* DemonicPossession: By the Bane of Anarchy in ''[[VideoGame/UltimaVIIPartII Serpent Isle]]''.
* DoomedHometown: The Lands of Danger and Dispair.
* DrivenToMadness: Suffers from this in ''VideoGame/UltimaIII'', [[AllThereInTheManual following a failed expedition to the Isle of Fire]]. Despite this, he can be found in a bar in-game, [[GameplayAndStorySegregation seemingly no worse for the wear]].
* [[spoiler:DidNotGetTheGirl]]: Was due to [[spoiler:marry Princess Beatrix]] shortly before [[VideoGame/UltimaI the Lands of Danger and Dispair]] [[RetGone disappeared]].
* ForestRanger: Whenever he is not saving the world, he prowls the wilds or meditates on the Virtue of Spirituality.
* HeirInLaw: Technically was ''almost'' this, in ''UltimaI''.
* HoistByHisOwnPetard: How he first met British - He was out chopping wood when [[OnlyKnownByTheirNickname the man who would be British]] suddenly came through a moongate. In his surprise, [[AgonyOfTheFeet he accidentally swung the axe into his own leg]]. Fortunately, [[OnlyAFleshWound he had a magic cantrip onhand to heal it]], inadvertently introducing the man to magic.
* JackOfAllStats: [[JustifiedTrope Justified]], as he represents Spirituality, which in this game is defined as being spiritually balanced. Shamino is therefore balanced in all stats.
* LightningBruiser: To make up for his lost magical powers in ''Ultima V'', he is made the fastest character in the game alongside Toshi, as well as a decently strong fighter.
* MadnessMantra: Said to have been found repeatedly muttering the tagline for [[VideoGame/UltimaIII the third game]] during his first [[DrivenToMadness bout with madness]]:
-->"From the depths of hell, he comes for vengeance!"
* OlderAndWiser: To the Avatar and his other companions.
* RichesToRags: Following the disappearance of the Lands of Danger and Dispair.
* [[UptownGirl Uptown Man]]: [[RagsToRoyalty Went from being a simple woodsman to ruling]] at least half the [[VideoGame/UltimaI Lands of Danger and Dispair]], until it [[RetGone disappeared]].
* YouCantGoHomeAgain: His kingdom is destroyed along with most of Sosaria during the Age of Darkness, [[NoOntologicalInertia following the death of Mondain]].
* WeAreAsMayflies: Despite not being from Earth, he ages just as slowly, compared to the average person in his world.

A [[ThePaladin paladin]] and the mayor of Trinsic. [[spoiler:Dies by HeroicSacrifice in ''VideoGame/UltimaVIIPartII'' but is brought back from the dead in ''VideoGame/UltimaIX''.]] Dupre embodies the Virtue of Honor.

%%* TheAlcoholic
* AnimalMotif: Since his introduction in ''II'', he has always been associated with the RunningGag of ducks.
* BadassNormal: Was once a MagicKnight until he lost magical ability in ''Ultima V''. This doesn't stop him from using his raw strength to achieve ends.
* TheBigGuy: While ultimately serving as the Avatar's [[TheLancer lancer]], he becomes the muscle of the party when Geoffrey [[DeskJockey becomes captain of Britain's royal guard]].
%%* BoisterousBruiser
* DemonicPossession: By the Bane of Wantonness in ''[[VideoGame/UltimaVIIPartII Serpent Isle]]''
* HeroicSacrifice: [[spoiler:In ''Ultima VII Part II'', he drops into the Avatar's incinerator so his ash can be used to reunite the Banes of the Chaos Serpent.]]
* TheLancer: In later games, he was established as the closest and most trusted of the Avatar's companions.
* MagicKnight: In ''Ultima IV'' only. Ironically, the Paladin class in general is given an intelligence bonus, and has the same magic ability as Rangers and Bards.
* MightyGlacier: In ''Ultima IV'' and ''V'', where he has a high strength but low dexterity. In later games, he has the potential of becoming a LightningBruiser.
* MyGodWhatHaveIDone: After being free from the Bane of Wantonness. [[spoiler:This is what drives his HeroicSacrifice.]]
* ThePaladin: Whenever he is not saving the world, he is busy serving as a role model of honorable conduct to the people of Trinsic.
* UndyingLoyalty: Being the embodiment of Honor.

A fighter, later captain of the guard in Jhelom. Geoffrey embodies the Virtue of Valor.

* TheBigGuy: Is known as "Geoffrey the Giant" in ''III'', and has the size and strength to back up that name.
* BloodKnight: A benevolent example; he yearns for battle as much as he does for [[JumpedAtTheCall adventure]].
* DeskJockey: Became captain of Britain's royal guard in ''Ultima VI'', where he became too consumed by responsibilities to join the Avatar's party.
* LightningBruiser: In ''Ultima V'', where he has the most strength of the Fighter class, as well as the second-most dexterity (behind Shamino).
* MightyGlacier: In ''Ultima IV'', he is the strongest companion, but only slightly faster than Dupre.
* JumpedAtTheCall: Being the embodiment of Valor, he's always enthusiastic about going out on an adventure. Even before his exploits with the Avatar, he explored and mapped the Perinian Depths.
* PapaWolf: "The Tale of Geoffrey and the Dragon" tells about how Geoffrey--then only fourteen years old--defended his sister from a malicious dragon by holding him off, despite being unable to actually fight back.

A tinker from Minoc. Has a crush on the (male) Avatar. Julia embodies the Virtue of Sacrifice.

* FieryRedhead: She is often depicted as a redhead, and more consistently than that as the most temperamental of Avatar's companions.
* GenderFlip: Was made into a male named "Julius" in the NES port of ''Ultima IV''.
* MightyGlacier: In ''Ultima V'', she is this by her class' standards; she is stronger but slower than the typical bard.
* {{Tsundere}}: ''Ultima XI'' reveals that she had been in love with the Avatar for many years. She is also temperamental, especially if the Avatar dismissed her from the party in ''VI'' and ''VII''.
* WrenchWench: Julia is an exceptional craftswoman, working with all kinds of contraptions but eventually specializing in musical instruments.

A druid and the leader of LaResistance during [[VideoGame/UltimaV Lord Blackthorn's rule]]. Jaana embodies the Virtue of Justice.

* {{Druid}}: When she is not saving the world, she tends to the forests in north-western Britannia.
* LoyalAnimalCompanion: Her [[NobleBirdOfPrey hawk]] in ''Ultima VII''.
* RebelLeader: In game five, she heads the rebellion against Lord Blackthorn in the absence of the Avatar.

A shepherd and the only survivor of the old Magincia that fell to demons. Katrina embodies the Virtue of Humility.

* CrutchCharacter: In ''Ultima V'' and ''VI'', she joins the party at a later level (giving her a higher amount of hit points) to make up for her otherwise underwhelming stats. Because of how leveling up works in these games,[[note]]Each level takes twice as much EXP to reach as the previous level.[[/note]] the rest of the party will be able to catch up to her before she can reach the next level.
* HumbleHero: Being the embodiment of Humility.
* JokeCharacter: [[JustifiedTrope Justified]], as she represents Humility, and has nothing to boast about.
* TheLoad: In ''Ultima IV''. Being a shepherd, she is the least combat-oriented party member--which is why you will probably recruit her last, making her suffer from LateCharacterSyndrome and CantCatchUp on top of that. However, unless you play as a Shepherd yourself, you will ''have'' to recruit her before you are allowed to enter the Abyss.
* SoleSurvivor: When you meet her in ''Ultima IV'', Katrina is the last person still alive in the city of Magincia, which fell to the demonic onslaught after succumbing to pride. As a result, she became the paragon of Humility.

A mage and an adventure seeker. Mariah embodies the Virtue of Honesty.

* DeskJockey: Became a scholar in ''Ultima VI'', where she helps the Avatar in more indirect ways.
* SquishyWizard: Has the lowest Strength of the Companions, but has the highest magical capacity to make up for it.

!!Other Good Guys and Girls

* AuthorAvatar: Of Richard Garriott.
* BadassGrandpa: In ''Ultima V'', he went to the Stygian Abyss with an army to fight the demons and in ''Ultima IX'', he went back to the Abyss to fight Blackthorn all by himself.
* BigGood: British is King of Britannia
%%* DimensionLord: A rare good example.
* [[AFatherToHisMen A Father to the Avatar]]: British is a father figure to the Avatar, both praising him if he follows the Virtues and scolding him if he doesn't (or he dies).
* FishOutOfWater: When he first arrived in Sosaria. Though with the help of Shamino, he adapted to life in the area.
* GoingNative: As far as we know, he doesn't miss living on Earth.
* TheGoodKing: Generally benevolent to the Britannians, though the inhabitants of Serpent Isle may disagree.
* GoodIsNotNice: He banned those who didn't want to join the quasi-religion of the Eight Virtues to Serpent Isle, and he didn't attempt any diplomatic solution with the Gargoyles in ''Ultima VI''.
* LineOfSightName: Dubbed "British" by Shamino after telling him where he came from.
* TheMagnificent: Known as British, Champion of the White Light prior to attaining kingship.
* NoNameGiven: It's never stated what his true name is.

* RagsToRoyalty: Went from being a FishOutOfWater disgruntled British youth TrappedInAnotherWorld to powerful NighInvulnerable ruler of Sosaria.

An entertainer, scholar and explorer. Married to Iolo.

* AgeLift: Despite being portrayed as middle-aged in nearly every game, ''Ultima IX'' for some bizarre reason changes her to looking like she's only in her 20s or 30s. This has the amusing side-effect of making her relationship with Iolo into a MayDecemberRomance.
* HappilyMarried: With Iolo.
* SpellMyNameWithAnS: Called "Gwino" in some of the early games.
* WeAreAsMayflies: Humans from Earth age much more slowly in the world of Sosaria.

* EvilSorcerer: Unlike Lord British, who uses his powers for good, Mondain instead tries to subjugate the whole world with them.

In the sixth game, the Gargoyles summoned Mondain's spirit to embody their virtue of Control, along with Minax and Exodus. Finally, the Guardian, the villain of all subsequent games from ''VI'', was initially planned to be revealed as the combined form of the Shadowlords after they were cast into the Void, but this was axed.

A genius apprentice of Mondain who tries to avenge him in the second game. While not as indestructible as Mondain, she takes a lot more precautions to become ''unreachable'' by the heroes.

* AvengingTheVillain: Her motivation in ''Ultima II'' is to avenge her teacher and lover Mondain.
* BigBad: Of ''Ultima II''.
* CreepyChild: She was only 11 when Mondain took her in, and likely was still a kid when Mondain died.

%%* AntiVillain: In ''Ultima V'', then he becomes a straight one-dimensional villain in ''Ultima IX''.

* AnthropomorphicPersonification: Of hatred, falsehood and cowardice--the antitheses of Love, Truth, and Courage, the three principles at the base of the Eight Virtues.
* BigBad: Of ''Ultima V''.
%%* BlackCloak
* BrokeYourArmPunchingOutCthulhu: Assuming the Avatar tries to fight them. Not only are they a borderline HopelessBossFight (defeating one isn't impossible, but the fight is designed be as close as it can get without them being invincible), but they will just return anyways.
%%* CastingAShadow
* TheCorrupter: They turned Lord Blackthorn into their puppet, and made almost everyone else in their presence hateful, cowardly, and dishonest.
* {{Expy}}: Of the Nazguls from ''Literature/LordOfTheRings''.
%%* HumanoidAbomination
* ImmuneToBullets: Only certain artifacts can destroy them.
%%* InTheHood
* SheatheYourSword: The only way to defeat the Shadowlords is to [[spoiler:summon them to their corresponding Flames of the Principles, then cast their respective gem shards into the flames]].
* TwoGuysAndAGirl: If ''Martian Dreams'' is any indication.
* VillainHasAPoint: In ''Martian Dreams'', Astaroth makes a statement that is correct not only in [[VideoGameCrueltyPotential the series' universe]] ([[SeriesContinuityError barring]] ''VideoGame/UltimaIX''), but also [[SomeAnvilsNeedToBeDropped real life]]:
--> "Alas, no soul in life can be purged completely of virtue or vice. My lesson for you is simply that while pursuit of virtue is long and difficult, vice is found easily and is strongly linked to pleasure."
