!!Lizardmen / Dragonewts

[[folder:In General]]
A group of humanoid lizards that were once in the same danger of being devoured by the orcs as the Kijin, until Rimuru helped them survive. Some of them, namely Gabiru and his sister, joined the city of Tempest after the events.
----
* InstantAwesomeJustAddDragons: Evolving turns them from Lizardmen into Dragonewts, giving them the properties of dragons, including enhanced physical strength, wings for flight, and a fiery BreathWeapon.
* LizardFolk: Lizardmen are exactly as the name says, bipedal humanoid lizards. Becoming Dragonewts has them retain said lizard-like appearance while simply adding extra features based on dragons.

[[folder:Gabiru]]
[[quoteright:240:https://static.tvtropes.org/pmwiki/pub/images/ch17_body.png]]
-> '''Voiced by''': Creator/JunFukushima (Japanese), Creator/AustinTindle (English)

The son of the Lizardmen Tribe chieftain and the self-proclaimed hero of his nation. Incredibly arrogant and haughty, he gets his comeuppance quite rapidly, after which he follows the same DefeatMeansFriendship dynamics with Tempest.
----
* AssInAmbassador: He spends his first meeting with Rimuru's village constantly insulting Rimuru for being a slime and treating his followers as if they were pathetic weaklings. It's just a few sentences in before Benimaru is asking Rimuru for permission to kill him. The ironic thing is that Gabiru was supposed to be there to ask for their help.
* BadassBoast: He gives a surprisingly impressive one to a [[spoiler:church]] soldier.
--> "[[MyNameIsInigoMontoya My name is Gabiru.]] There is no need for you to remember, for it shall be your memento to the Netherworld!"
* BladeOnAStick: His main weapon is a spear, and he obtains his father's [[ProngsOfPoseidon Vortex Spear]].
* BoisterousWeakling: Well, he's not exactly ''weak'' but more undisciplined and completely unused to actual combat against enemies that can match his strength. When he's pitted against Gobta by Rimuru he makes a big show of his attacks instead of being cautious and winds up getting caught completely off guard by Gobta knowing the "Shadow Movement" skill. He fares better against the Orc General due to realizing he can't afford to hold back anything, but even with his father's Vortex Spear he can barely stand his ground, much less actually win.
* CrouchingMoronHiddenBadass: Getting his strength and abilities massively boosted after pledging loyalty to Rimuru did nothing to erase his comically boastful attitude and overall idiocy, simply making him understand reality enough to know his place, which still results in him frequently acting as comic relief from doing dumb things. Enemies would do best not to underestimate him, though, as there is a good reason why he and his Lizardmen group are part of the frontline forces for Rimuru's army, best displayed when he goes LetsGetDangerous and crushes several knights following a BadassBoast.
* DefeatMeansFriendship: Joins Rimuru after the Orc Lord is defeated and he himself is banished for his (admittedly well-intentioned) treason against the Lizardmen.
* DraconicHumanoid: Is a Lizardmen.
* DragonAncestry: Lizardmen claim to be descended from dragons.
* TheExile: ''Technically'' became this to the Lizardman tribe for his well-intentioned treachery during the Orc Disaster crisis and forbidden from returning until he proves his worth, though in practice it was more formality since his father still dearly loves him and had to punish him ''somehow'' to appease their law, with it being implied their father sent Souka to Tempest in part to keep an eye on him. He redeems himself after Rimuru awakens as a Demon Lord and he himself is promoted to an executive position within Tempest.
* FaceDeathWithDignity:
** With the Orc General's ax bearing down on him and no time nor energy to react, instead of panicking, he simply closes his eyes and calmly awaits his inevitable end. Luckily TheCavalry shows up at that exact moment.
** When he believes his father intends to kill him for his treason, he not only fully accepts the punishment, but even considers it is only right for what he did.
* AFatherToHisMen: He refuses to let his subordinates join him in fighting the Orc General due to the difference in power, and he's reduced to tears when they throw themselves in front of him to save him from Gelmud's magic attack. When Rimuru throws him healing potions, he scrambles as fast as he can to use them on his downed comrades, and this act of selflessness is what makes Rimuru's opinions of him become much more favorable.
* FearlessFool: About the only positive thing about Gabiru Rimuru can get from his initial impressions is that he's [[BrassBalls incredibly brave]], as shown when he's the only Lizardman not cowering in fear before an angry Ranga at his full size. Combined with his ego, however, it just makes him all too willing in jumping into situations without thinking.
* FoolishSiblingResponsibleSibling: He more or less plays the Foolish Sibling to Souka's Responsible Sibling. While Gabiru was off doing whatever upon being named, and in general being way too full of himself, Souka was doing her job as the captain of the guard, keeping her father and her people safe.
* HeroicBSOD: He hits his when he learns straight from Gelmud's mouth that in the end he was just an UnwittingPawn meant to be eaten by the Orc Lord in order to fuel his ascent to Demon Lord, and it only gets worse when those amongst his admirers [[TakingTheBullet throw themselves in front of Gelmud's attack to save him and nearly die]]. He's reduced to crying by the end as Rimuru hands him healing potions that he desperately uses on his men as fast as he can.
* AHeroToHisHometown: Other members of the Lizardman Tribe ''love'' this guy, mostly because of the prestige that actually having a name provides. Unfortunately, this has the side effect of stroking his ego, preventing him from really worrying about improving himself and making him seem pompous and irritating to outsiders.
* HiddenDepths: Deep down he questions his own hype and does seem to genuinely want to make sure his father can retire with peace of mind. He is also surprisingly not a terrible tactician, and knows how to plan battles in such a way as to exploit the Lizardmen's advantages over the Orcs in their native terrain, though his plans fail because he went into battle without bothering to learn anything about his enemy.
* LetsGetDangerous: While he already got more badass and capable overall after pledging loyalty to Rimuru, most of the time he still acts as boastful comic relief. However, there are times when he gets completely serious, during which he leaves out any boasting about his greatness, simply stating his name before getting straight to destroying his enemies.
* NormalFishInATinyPond:
** Played straight before [[OutsideContextProblem Rimuru's]] appearance, as he ''does'' have all the advantages he brags about when compared to the average Jura Forest inhabitant — who were mainly low-level monsters like goblins or kept to themselves like dryads.
** Inverted after Rimuru appeared and started his nation-building quest. Gabiru is near-worshipped by his fellow lizardmen and is special among them due to having a name and having all the benefits it provides. However, when compared to those who follow Rimuru, who takes it upon himself to give ''everyone'' under him a name and on top of being stronger than the one who gave Gabiru his, he's become a bombastic but average fish for his more powerful than usual pond.
** Played straight ''again'' following him becoming a subordinate of Rimuru, but going from the opposite direction. As part of Rimuru's forces, there are plenty of people like the kijin that are stronger than him, something he's humble enough to acknowledge. To most people ''outside'' Rimuru's army, he's got the abilities of a decently strong Dragonewt that can crack the ground with a little force and slaughter several soldiers in seconds.
* OhCrap: He has one when he [[TheForceIsStrongWithThisOne senses the power of a large Orc]] and assumes it's the Orc Lord. It only gets worse when the orc reveals it's "just" an Orc General and far inferior to the true Orc Lord, and it reaches its zenith when despite giving a good fight he can't defeat it.
* PowerGivesYouWings: After receiving a powerboost from being renamed by Rimuru, he grows a pair of wings.
* ProngsOfPoseidon: He wields his father's Water Vortex Spear, initially taken during his coup to fight the orcs, and then willingly given to him shortly after his exile as a show that his father still loves him despite everything. As the name suggests, it can create and manipulate [[MakingASplash powerful water attacks]].
* PurpleIsPowerful: After receiving his powerboost and evolution from being named by Rimuru, his green skin turns purple.
* SmallNameBigEgo: A zig-zagging example. He ''does'' have an inflated sense of self-worth about being the Lizardmen Chieftain's son and possessing a name, but there are multiple points where he honestly questions if he's hyping himself up too much or that he's not good enough. His lizardmen comrades, on the other hand, are all too willing to stroke his ego to keep him going even further and burying his doubts.
* TookALevelInBadass: Accidentally gets named by Rimuru who states out loud that his current name is fine, [[PowerGivesYouWings granting him wings and a major boost in power.]] [[spoiler: Believe it or not, he eventually becomes one of the 12 entities serving under Rimuru considered strong enough to be individual Demon Lords.]]
* UnwittingPawn: Gelmud plays on his ego and desire to protect his people to make him overthrow his father and take control of the Lizardmen, relying on Gabiru's lack of knowledge about the Orc Lord's abilities to make him commit to a direct assault against the Orcs and get them wiped out to feed the Orc Lord's strength.
* WellDoneSonGuy: The light novels say his secret motivation is to gain his father's approval, even when overthrowing him. This trait eventually gets carried over when he is exiled to Tempest, wishing to gain Rimuru's approval.
* WellIntentionedExtremist: His desire to protect his people from the Orcs drives him to betray his father and chieftain to seize power over the Lizardmen, which in and of itself [[UnwittingPawn is a ploy by the demon Gelmud and his comrades to slaughter the Lizardmen]].
[[/folder]]

[[folder:Gabiru's Group]]

A group of Lizardmen who are fantastically devoted to Gabiru, and who answer to his beck and call.
----
* NiceJobBreakingItHero: Their hero worship of Gabiru prompts him to stage a coup against his father in an attempt to fend of the invading orcs. This backfires spectacularly, as they find themselves outmatched against the orcs, and his father's pleas to ally with Rimuru proves to be the correct decision.
* SatelliteCharacter: An entire group of them for Gabiru.
* TakingTheBullet: When Gelmud attempts to murder Gabiru, they willingly throw themselves in front of his attack to save their idol. They would have most likely died had Rimuru not given Gabiru some healing potions to save them.
* UndyingLoyalty: To Gabiru. When he's practically exiled from the clan, they meet with him and reveal they've volunteered to join him in exile to be with him.
[[/folder]]

[[folder:Souka]]
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/souka.png]]
-> '''Voiced by''': Creator/RumiOokubo (Japanese), Creator/CaitlinGlass (English)

The younger sister of Gabiru, and the former captain of the guard. She left her clan in order to join Tempest so she could further enhance her skills, an order given by her father.
----
* ActionGirl: She's the captain of the guard for a reason. This becomes especially more prominent after being named.
* BishonenLine: Sure, every monster goes through this after being named, but it's notable with Souka and her aides because they go from clearly lizardlike humanoids, to essentially humans with draconic wings, horns, and notable fangs. The change is even more notable when compared to Gabiru and his men, who merely gain a power boost and wings.
* CuteLittleFangs: These, alongside her draconic traits, are the only things separating her from humans after being named.
* CuteMonsterGirl: Even before evolving from being named, Souka had a notably softer look compared to the rest of the lizardmen.
* DaddysGirl: It's subtle, but Souka seems to hold a great affection for her father: She stayed by his side during the Orc trouble, she's the one to help him stand up after rescuing him after Gabiru's betrayal, and she's goes to Tempest on his orders.
* TheDutifulSon: She acted as this during her time as the captain of the guard, helping protect the temple.
* {{Ninja}}: As a member of Souei's Shadow Squad, she dresses like a [[HighlyVisibleNinja stereotypical anime ninja]] and practices the same stereotypical anime ninja tropes that Souei does.
* NumberTwo: She becomes Souei's second-in-command of the Shadow Squad.
* SubordinateExcuse: She has an obvious crush on her teacher and superior Souei.
* WingedHumanoid: Once she becomes a Dragonewt, she resembles a human woman -- though she can sprout draconic traits like horns, wings, and a tail at will.
[[/folder]]

[[folder:Touka, Saika, Nansou, and Hokusou]]
A group of Lizardmen that accompanied Souka when she entered Tempest. They were named by Rimuru and now form the Shadow Squad, along with Souka and Souei, who act as their leaders.
----
* TheApprentice: Along with Souka, to Souei.
%%* TwoGirlsToATeam
* WingedHumanoid: Same deal as Souka.
[[/folder]]

!! Orcs

[[folder:In General]]
A race of boar-like humanoids who were once controlled by the Orc Disaster. They were actually a tribe of Orcs who were suffering through a great famine, and most of them were brainwashed by the effects of Starved into trying to devour everything and everyone to satiate their hunger. Once everything is cleared up and the effects of Starved are gone, the Orcs become part of Tempest's workforce.
----
* CannibalismSuperpower: Under the influence of Starved, they could assimilate traits from other monsters they devoured -- like obtaining scales and webbed toes from eating Lizardmen.
* DeathOfAChild: Even the children who weren't lucky enough to get food for the famine wound up hitting the dirt bed.
* HeelFaceTurn: Once the effects of Starved are over and they're allowed to live in Tempest, they swear loyalty to Rimuru and become the main construction force of the city.
* MyGodWhatHaveIDone: The Orcs were ''horrified'' at what they'd done once the effects of Starved wore off. It was only Rimuru offering to "eat" their sins that managed to snap them out of it.
* VillainousGlutton: Back when they were under the effects of Starved, they would devour anything and anyone they came across, including their own dead, to become more powerful.
[[/folder]]

[[folder:Geld II]]
[[quoteright:200:https://static.tvtropes.org/pmwiki/pub/images/geld.png]]
-> '''Voiced by''': Taro Yamaguchi (Japanese), Creator/CrisGeorge (English)

The son and former right hand to the Orc King, who then became an Orc Disaster to try and prevent a famine. He was one of the survivors of the attack against the Starved Orcs, and was later named by Rimuru to carry the legacy of the good king.
----
* TheAtoner: He desperately wants to make up for the transgressions of the Orcs, even knowing it was a DealWithTheDevil situation with no good ways to end.
* BerserkButton: Killing your allies, especially for the sake of power, is a good way to get on his bad side since it reminds him too much of what his people did under the effects of Starved. ''Eating'' your allies in order to gain said power makes him even angrier, ''especially'' due to what Starved made his people do. When Shogou murders Kirihara, followed by eating her flesh in the light novel, to gain the [Survivor] skill, Geld forgoes a clean kill in favor of giving him a NoHoldsBarredBeatdown and then letting his new HealingFactor kick in to prolong his suffering.
* CombatPragmatist: He bluntly tells Shogou when the latter tries to call him a coward for wearing armor that when in war, fighting with any advantage you can get is the only proper way of showing courtesy to your opponent, since it shows you're taking the fight and victory seriously.
* EveryoneHasStandards: While he didn't have a very high opinion of Shogou during their fight to start with, seeing him willingly murder his comrade Kirihara for a power boost and healing tanks any sort of respect he might have had for him even as a warrior.
* FasterThanYouLook: He prefers a StoneWall strategy, but after reaching the limits of his patience with Shogou after watching him kill Kirihara, he engages the [[ArrogantKungFuGuy boastful]] Otherworlder in hand-to-hand combat and easily dodges his first strike before suddenly smashing him into the ground and delivering a NoHoldsBarredBeatdown.
* IAmNotLeftHanded: As shown by his fight with Shogou, his regular fighting style is to act as a StoneWall, tanking attacks in order to trick enemies into getting afflicted with his [[MakeThemRot Corrosion]] skill, and quickly exploiting the paralysis to split their skull with his cleaver and end their suffering. But when his opponent shows that they don't deserve such mercy, he puts away the cleaver and switches to a GoodOldFisticuffs LightningBruiser style, pummeling the enemy rapidly and repeatedly while applying Corrosion, for the deliberate sake of dragging out their pain and agony in order to express how serious and furious he is, before eventually killing them.
* LegacyCharacter: Named after the very Orc Disaster he once served, so that he could honor his father's legacy.
* MacheteMayhem: He wields a large cleaver much like his father did into battle.
* MakeThemRot: He has his father's [Corrosion]/[Rot] skill, which allows him to manifest demonic snake-like creatures that bite his opponents and forcibly rot their flesh.
* StoneWall: Geld marches into battle with a shield and covered in armor. When he doesn't have a weapon, he relies on his [[MakeThemRot Corrosion]] to wear the enemy down. However, it's shown when sufficiently pissed off, he turns into a LightningBruiser who moves [[FasterThanYouLook much faster than someone of his bulk and armor should]].
* {{Workaholic}}: Geld has a very bad habit of working past his limits.
[[/folder]]

!!Primordial Demons
[[folder:In General]]
The four primordial demons that come to serve under Rimuru out of respect for his strength. Diablo came to his call during his Harvest Festival to become a Demon Lord, while Ultima, Testarossa, and Carrera were recruited by Diablo in order to make his personal work easier.
----
* BloodKnight: While their exact attitude towards it varies from demon-to-demon, all four absolutely love fighting.
* ColorCodedForYourConvenience: As primordial demons, prior to being named by Rimuru they only had their signature colors to go by for names: Noir/Black for Diablo, Violet/Purple for Ultima, Blanc/White for Testarossa, and Jaune/Yellow for Carrera.
* MonsterProgenitor: They are four of the 7 original progenitor daemons. As such, their age and power let them bypass most of the restrictions daemons have when they incarnate physically on earth.
* StrongerWithAge: Demonic spirits overall follow the idea of getting stronger the longer they live, and as all four are Primordial demons that are on par with Guy Crimson in terms of how long they've lived, they are also among the strongest beings in the world.
* VehicularThemeNaming: Rimuru named Diablo such both because it literally means "devil" and because it was the name of a sports car (specifically a Lamborghini Diablo). All following primordials were given sports car names as a deliberate theme: Ultima from the Ultima GTR, Testarossa from the Ferrari Testarossa, and Carrera from the Porsche Carrera.
[[/folder]]

[[folder:Diablo]]
[[quoteright:220:https://static.tvtropes.org/pmwiki/pub/images/diablo.png]]
[[caption-width-right:220:The Black Progenitor]]
-> '''Voiced by''': Creator/TakahiroSakurai (Japanese), Creator/DamanMills (English)

An ancient and powerful archdevil known as the Black Progenitor, who was summoned by Rimuru during his ascension to Demon Lord. Named Diablo, he evolved into a Demon Duke; and worships Rimuru as a god.
----
* AdaptationDyeJob: In the original web novel he has solid red hair, but in the light novel and subsequent adaptations he has black hair with red and yellow streaks.
* AnArmAndALeg: He lost an arm when he tried to slash through Shizu's anti-demon mask, though she noted he was holding back.
* BattleButler: He is employed as a butler and leads the Black Numbers -- a corps of demon butlers and maids.
* {{Bishonen}}: Upon manifesting, he assumes the form of a beautiful, androgynous man.
* BlackEyesOfCrazy: His bloodthirsty demonic nature is highlighted by eyes, which have black sclera with red markings and yellow irises.
* BloodKnight: His love of elegance and gracefulness aside, Diablo ''really'' likes fighting, and before being summoned and named by Rimuru he was often bored out of his mind by the fact he rarely got to face off against opponents worth his time. Part of the reason he answered Rimuru's summonings was specifically ''because'' [[IFightForTheStrongestSide Rimuru is strong, surrounded by powerful subordinates, and often fights powerful foes]].
* CharmPerson: While his sheer power was already quite good at drawing others to desire serving him, becoming Rimuru's subordinate granted him the Unique skill "Tempter", utilizing the sub-skills Thought Domination, Charm, and Solicitation to completely bend the minds, bodies, and very souls of its targets under his will, turning them into blindly loyal servants.
* CreepyGood: He has one of the most stereotypically RedAndBlackAndEvilAllOver appearances possible for a demon, and his BloodKnight mentality means he can get rather terrifying when having "fun", but all the same he's a bizarrely moral demon who not only keeps the letter of his word but also the spirit of it, along with being willing to help people in need when they desperately ask him, such as when Tiss was about to be killed by a lesser demon and she demon summoned as a last resort, with Diablo letting her keep her soul on the simple condition of keeping his appearance a secret.
* CurbStompBattle: He treats his fight with Razen, TheArchmage of the Kingdom of Falmuth [[spoiler:further boosted by using the body of the Otherworlder Shogou]], like a mildly amusing workout at best.
* DarkIsNotEvil: His status as the Black Progenitor means his very existence is associated with both the color black and darkness as a whole, possessing an appearance that just ''screams'' RedAndBlackAndEvilAllOver, and the ways his powers manifest is through blatantly dark and evil-looking forms like stereotypical demon wings or long WolverineClaws. Same goes for his descendants, who possess both the darkest color schemes out of all demons and more demonic-looking powers. Despite '''all''' of this, not only is Diablo a major case of a NobleDemon who evolves into being CreepyGood under Rimuru, but every one of his descendants have the highest levels of morality and personal standards out of all demonkind.
* ADogNamedDog: As noted by Rimuru himself, he's a demon effectively named "demon", though Rimuru did put a decent amount of thought into it by making it both in Latin/Spanish and also having it shared with a sports car.
* DealWithTheDevil: What he would do to pass the time while bored before being summoned by Rimuru. In exchange for [[YourSoulIsMine his summoner's soul]], he would destroy their enemies utterly.
* DemonLordsAndArchdevils: He was originally a nameless Archdevil, before evolving into a Demon Duke upon being named [[spoiler:and eventually becoming a Demon God. He also holds the title of Demon Lord thanks to Rimuru upgrading him.]]
* EveryoneCallsHimBarkeep: Before he was named, he was simply referred to by others by his signature color -- Noir/Kuro/Black.
* {{Expy}}: Rimuru making him a butler was a nod to Sebastian Michaelis from ''Manga/BlackButler''.
* HunterOfHisOwnKind: In the past, Diablo was summoned by one of the members of a team of heroes called the Silver Knights in order to avenge them. [[spoiler:Their killer was the archdemon Orthos, who was powerful enough to defeat Shizu -- albeit only after she was weakened by a duel with Kuro. After mopping up the lesser demons serving Orthos, the Black Progenitor rescued Shizu and utterly destroyed Orthos with ease -- despite technically being of the same rank as Orthos, without a name of his own, and missing an arm.]]
* MulticoloredHair: While he had solid red hair in the original web-novel; in the light novel, manga, and anime he has black hair with red and yellow streaks.
* NobleDemon:
** While he utterly loves fighting and beating people up, whether into unconsiousness or death not really mattering to him, along with taking the souls of both dealmakers and his enemies, he's a generally decent guy who, even before being summoned by Rimuru, had plenty of standards. He only took the souls of people who genuinely were fully willing to die to have him accept a job, he always completed his deals to the letter even if the soul payment was lacking, viewing the souls of his targets as evening things out, and he was willing to give people that accidentally summon him out of desperation a simple agreement to keep his presence secret while letting them keep their souls so long as the deal was upheld.
** It's later revealed that being a NobleDemon is actually an inherent aspect of his very soul, as the very few demons that align with his "black" color (he just isn't very interested in creating tons of demon descendants like other Primordials) also possess very noble qualities, such as Beretta holding genuine loyalty to Ramiris not out of strength, since his true summoner Rimuru is stronger, but out of close companionship with her. Guy is able to realize Diablo has thrown his lot in with Rimuru simply from noticing this second-handed through Beretta long before the two Primordials ever meet each other again face-to-face.
* NotSoStoic: The normally composed and suave Black Progenitor is left in shock and disbelief after properly introducing himself to Rimuru only to be asked confusedly who exactly he is. It gets to the point it looks like he's about to ''cry'' when Rimuru cheerfully tells him he's free to go if he wants and he quickly reaffirms he wants to serve him.
* TheOneGuy: While gender doesn't really matter for [[OtherworldlyAndSexuallyAmbiguous demonic spirits who normally have no sex at all]], out of the four Primordials under Rimuru he's the only one that identifies as male, whereas the other three possess the appearances and personas of women.
* TheRival: To Shion, who he competes with for the position of Rimuru's number-one aide.
* SlasherSmile: When summoned by one of the members of Silver Knights to take revenge on the archdemon that mortally-wounded her and killed her partner, he sports a bloodthirsty grin while saying he'll reap her enemies to make up the rest of what he's owed.
* VoluntaryShapeshifting: He can form [[GoodWingsEvilWings bat wings out of his back]] and turn his hands into extendable WolverineClaws.

!!!Ranga
[[quoteright:270:https://static.tvtropes.org/pmwiki/pub/images/ranga_tensura.png]]
-> '''Voiced by''': Chikahiro Kobayashi (Japanese), Creator/TysonRinehart (English)

A Dire Wolf that evolves into a Tempest Wolf after being named by Rimuru and later still into a Tempest Star Wolf. He and his pack became Rimuru's followers after he killed his father, holding no grudge against him.
----
* BashBrothers: Well, Bash Brother and Sister in this case, but he and Shion team up against Charybdis when the giant monster attacks.
* BigFriendlyDog: After evolving. This becomes especially pronounced whenever he's in his true form, which is so big, it can hardly fit into the classroom of the Summoned Children.
* BlackEyesOfCrazy: Averted. The sclera in Ranga's eyes is completely black, and yet he's among the most noble members of Tempest.
* BlowYouAway: Receiving a name evolved him to a Tempest Wolf, giving him power over wind.
* CanisMajor: While being a direwolf already made him a good deal bigger than normal wolves, after he evolves he becomes outright massive in size, towering over most of the other characters, though he can shrink down to his original decently big size at will.
* DefeatMeansFriendship: After his father is killed, he and his pack swear complete allegiance to Rimuru.
* DoesNotKnowHisOwnStrength: At first, he had trouble controlling the whirlwinds he causes with his tail.
* EvolutionPowerUp: Evolves into a Tempest Wolf after being named by Rimuru, then later still evolves into a Tempest Star Wolf during the battle with the Orc Lord's army.
* GentleGiant: Ranga's true form towers over quite a few characters, but as long as they're on Rimuru's good side, he's easily one of the most affectionate wolves you'll ever meet.
* HiveMind: How he explains the reason why naming only him was enough to evolve all of the direwolves. According to him, they share one mind, and so by naming him, the current leader, the other wolves got to evolve as well.
* KnowWhenToFoldEm: Once his father is killed, and Rimuru uses his newly acquired "Intimidation" skill on him, he's the first to surrender to Rimuru's authority, with the rest of the direwolves surrendering soon after.
* LoyalAnimalCompanion: Becomes one to Rimuru, acting more or less like his pet, and always by his side or hidden in his shadow.
* NobleWolf: Unlike his overconfident father, he is friendly and very loyal.
* ShadowWalker: Ranga and all the Tempest Wolves have the "Shadow Movement" skill allowing them to hide and appear from shadows even a great distance away.
* ShockAndAwe: He can shoot lighting strikes from his horns.
* SizeShifter: He develops the ability to change his size after Rimuru gives him a name; he starts out massive, but later shrinks to merely larger than average for a wolf for practicality.
* SupernaturalGoldEyes: His pupils are golden, and both his fur color, star-shaped mark, and abilities after evolving make it quite clear that Ranga's quite supernatural compared to his fellow Tempest Wolves.
* TurnTheOtherCheek: Rimuru directly asks him about how he feels about the fact that Rimuru killed his father. Ranga admits that he still thinks about it but is much more grateful towards Rimuru for sparing the rest of the Dire Wolves when he had them at his mercy and then granting them a clan name, evolving them into Tempest Wolves. Rather than be resentful, he'd much rather show his thanks through his clan's UndyingLoyalty.
* WeatherManipulation: During the battle with the Orcs, he uses the wide-range attack "Death Storm", which creates massive twisters all over the battlefield coupled with lightning bolts powerful enough to kill an Orc General with one shot.
* YouKilledMyFather: Subverted towards Rimuru, see TurnTheOtherCheek above.

[[quoteright:280:https://static.tvtropes.org/pmwiki/pub/images/trainee_anime.png]]
-> '''Voiced by''': Creator/RieTanaka (Japanese), Creator/JamieMarchi (English)

The head dryad of the Jura Forest, and one of the most powerful allies Tempest has in the early part of the story, as the dryads have the power over the forest itself. She asks Rimuru to deal with the orcs, seeing them as a threat to the forest and its inhabitants in general.
----
* BigEater: She helps herself to the food at the banquet, and as noted by Kaijin, she certainly can eat a lot.
* DoesNotLikeShoes: She is shown to not wear any shoes under her skirt in certain frames.
* EyesAlwaysClosed: She's usually depicted with her eyes closed. Them being open is usually a sign she's either angry and ready to fight, or being serious about something.
* GreenThumb: She's a dryad, so it's kind of a given that she'd be able to control plants.
* GotVolunteered: She has a habit of volunteering Rimuru to high ranking positions. Rimuru suspects that despite her being the one to have the higher authority, she just doesn't want to do it.
* NatureSpirit: As a dryad, she is a female PlantPerson; and was in charge of Jura Forest before designating Rimuru the king of the monsters there.
* PlantPerson: A dryad.
* TrademarkFavoriteFood: She can't go a chapter in the spin-offs without asking for some potato chips.
* YouGottaHaveBlueHair: She has green hair.

!!!Storm Dragon
[[quoteright:350:https://static.tvtropes.org/pmwiki/pub/images/veldora_dragon_anime.png]]
-> '''Voiced by''': Creator/TomoakiMaeno (Japanese), Chris Rager (English)

One of the Four True Dragons and the first intelligent being Rimuru meets after being reincarnated, he's the one who named him. He in turn received his last name from Rimuru. He had been sealed in a cave for three centuries when he met Rimuru, becoming his first friend.
----
* AdaptationalEarlyAppearance: In the manga and light novel, Rimuru gives him a body to inhabit after exchanging a few words to each other. In the anime, he gives him his body earlier after he awakens.
* BadassBaritone: In the dub, he has a deep voice -- underscoring that he's a powerful dragon-god.
* BloodBrothers: With Rimuru, his first true friend and a big brother figure.
* BloodKnight: While not malicious, he needs to cut loose every once in a while. This is one of the reasons for his sealment.
* DestructiveSavior: Near the end of the story he tries to make an apology of sorts to Ruminas for blowing up her kingdom that one time [[spoiler:only to destroy it again first through collateral damage and then accidentally turning the entire place into a forest.]]
* DramaticallyMissingThePoint: His perspective is given focus at the ends of volumes and, while he learns compassion and patience from Rimuru's memories, he still appreciates his actions from the perspective of an immortal unassailable dragon and not a humble mortal not fully aware or invested in their own power. In this way, he rationalizes Rimura's actions and luck as shrewd prudence and not the serendipity it is.
* TheDreaded: Very much so. He was indirectly responsible for the peace within Jura Forest due to his sheer presence alone. However, his disappearance sparks a war for territorial control between the monster races, at least until Rimuru arrives.
* HiddenDepths: His POV sidestory reveals he's picked up Shogi and gives Ifrit a handicap. He also takes to reading manga and quoting lines that he likes.
* HumanityEnsues: [[spoiler:After figuring out how to disable Unlimited Imprisonment, Rimuru discovered that Veldora got rid of his physical body -- not needing it while inside Rimuru -- and creates a duplicate body and sticks Veldora's soul inside of it. Veldora makes a few modifications -- turning the hair blond and making it taller and more muscular -- and then lets out an evil laugh while declaring his triumphant return and intent to annihilate any who oppose him. However, he spends most of his time lazing around reading manga.]]
* ImmortalImmaturity: Despite being one of the most ancient and powerful beings in the world, mentally Veldora is basically a somewhat bratty, self-centered teenager, full of petty impulses and uncontrolled whims, with Rimuru actually being a [[MentorArchetype more mature and responsible part]] of their friendship. This led to no end of annoyance from his older sisters, as they were basically stuck trying to raise him more responsibly.
* ImmortalProcreationClause: He implies he can breed but doesn't bother because living forever means he doesn't need to leave descendants. He says most magic born creatures think like that. Milim is also a good example as to why it would be a bad idea: When dragons reproduce, their power is almost entirely absorbed by their offspring. [[spoiler:And assuming Rimuru is Veldanava, it took one hell of a long time to reincarnate compared to normal, if he did at all.]]
* ImplausibleDeniability: He mentions that he destroyed a vampires' city out of pettiness, and then pretended he had nothing to do with it. Understandably, no one believed him.
* IntergenerationalFriendship: When they first met, Veldora was hundreds, if not thousands years old, and Rimuru was just 37 (or about 1 week as a slime). Ironically, he turned out much more mature than [[ImmortalImmaturity Veldora]].
* LargeHam: As expected from a dragon, he's bombastic and loud whenever he's excited.
* ReallySevenHundredYearsOld: He's practically ageless and has lived for centuries already. The three hundred years he's spent sealed up has him more worried that it'll kill him through the draining of his magic power than actually through old age.
* ResurrectiveImmortality: Like all true dragons Veldora can respawn after death, albeit without most of his previous incarnation's memories [[spoiler:(though Rimuru's two years housing Veldora granted him a skill to back-up Veldora's memories, ending this limit provided Rimuru's still alive)]]. This was something of a problem for his upbringing, as his oldest sister Velzard was so exasperated by his bratty attitude that she got into a habit of ''killing him'' and hoping maybe he'd learn something for his next reincarnation, but the memory loss always got in the way. Being completely drained by Unlimited Imprisonment would have [[FinalDeath killed him permanently]], though.
* SealedEvilInACan: He was sealed by the Hero for blowing too much stuff up, basically. He's not exactly ''malicious'' but he basically gets bored and goes on rampages every now and then. After being unsealed he contains himself by reading manga, griefing newbies inside the labyrinth and eating cake.
* ShipTease: He gets very familiar with Ifrit while they're both trapped within Rimuru. In the manga he thinks about giving him a woman's body with breasts to explore their appeal and in the anime spends an awkward amount of time holding his hand because he's warm.
* SmugSuper: He is an immortal among the four strongest beings on the planet and is exactly as arrogant as that would imply. He mostly grows out of it.
* SoreLoser: He keeps trying to find a way out of his loss to Ifrit in shogi before finally just awkwardly laughing to cover up his disappointment.
* TakingTheHeat: He happily took the blame for Rimuru [[spoiler:massacring 20,000 Falmuth soldiers]] to preserve Rimuru's peaceful reputation in politics. Seeing as how Veldora is already seen as a [[TheDreaded dreaded]] BloodKnight, it's not like taking the blame really affects him.
* {{Tsundere}}: He acts tough and aggressive, but can get flustered -- even called one by Rimuru when he denies something.
* UnskilledButStrong: Before his imprisonment, he just tended to throw his power around carelessly. His two elder sisters are actually weaker, but Velzard would always kick his ass because she had much better control of her abilities. Thanks to the influence of Rimuru's manga and the wisdom of the people around him, however, he starts seeing the value of concentrated strikes, holding back his immense power and using actual techniques. [[spoiler:By the end of the web novel, while Velzard is still generally considered to be the strongest dragon, he's improved at least enough to completely hand Velgrynd and titan Dagruel their asses, indicating that if he keeps it up he'll probably surpass Velzard as well.]]

[[folder:Ifrit/Charys]]
!!!Flame Lord
-> '''Voiced by:''' Creator/TakuYashiro (Japanese), Creator/ChrisGuerrero (English)

The being inhabiting Shizu, a flame spirit called forth by Leon with a taste for death and destruction. Originally contained by Shizu using both her mask and willpower, they eventually break free and try to resume their desires, only to be thwarted by Rimuru. They eventually form a friendship with Veldora, who convinces Rimuru to give them a new body, following which they're given the name "Charys".
----
* CallAPegasusAHippogriff: Though fire-related, in mythology an Ifrit is a type of genie rather than a giant or titan.
* DefeatMeansFriendship: After being devoured by Rimuru, they're spared by Veldora due to being bored and wanting someone to talk to. The two end up striking up a friendship, and Veldora eventually convinces Rimuru to give them a body to serve as his assistant, Veldora even naming them "Charys".
* DoppelgangerAttack: Ifrit can summon copies of themself made of fire to overwhelm the opposition.
* EnemySummoner: Ifrit can summon Salamander demons to aid them in battle, which [[PlayingWithFire breathe fire]] and can [[ActionBomb explode violently]].
* EvilIsBurningHot: They don't just have [[PlayingWithFire the ability to manipulate flames]], their very body constantly produces intense heat, enough to melt rock just by touching it. {{Subverted|Trope}} after befriending Veldora, since not only are they not evil anymore, their raging fiery aura gets tempered.
* FierySalamander: Can summon three of them in battle.
* HeelFaceTurn: After being devoured by Rimuru and bonding with Veldora, they are given a new body and a name, while swearing to serve Veldora.
* InstantRunes: Can create a magic circle without chanting.
* OhCrap: Ifrit gets several when they realizes their flames don't work on Rimuru, but their biggest is when they sees Veldora after they're devoured by Rimuru's Predator skill.
* PlayingWithFire: As the one that provides Shizu with her power, they go even further with it than her, having a variety of techniques involving the manipulation of flame.
* ScissorsCutsRock: Ifrit and their Salamander summons' flames are so intense that Rimuru attempting to use [[MakingASplash Water Blade]] on them just causes it to erupt into steam without effect, and Great Sage informs him that while if he unleashed all the water in his body at once he ''could'' overpower it, the resulting explosion of steam would take out the entire goblin village in the process. This forces Rimuru to rely on using [[AnIcePerson ice magic]] and his own immunity to flame to win.
* TheStoic: Their normal expression is an [[PerpetualFrowner indifferent grimace]], with most of their fight only having them change expression when casting magic. That said, dealing with Rimuru and then Veldora [[NotSoStoic causes them to lose their composure, expressing shock and fear]].

[[folder:Youm Farmenas]]
!!!Champion
-> '''Voiced by:''' Creator/YoshimasaHosoya (Japanese), Creator/DavidMatranga (English)

A warrior who initially encountered Rimuru after the Orc Disaster incident after being sent by Count Nidol Migam of the Kingdom of Falmuth to investigate, and also brought his assigned party to heel through force and charisma to free himself of the magically-binding contract he was under. He ended up joining forces with Tempest and taking credit for defeating the Orc Disaster while becoming a staunch ally of the monster kingdom.
----
* AintTooProudToBeg: When Myulan's involvement with the attack on Tempest was discovered and her punishment to be decided, Youm does not hesitate to beg Rimuru to spare the Majin, reasoning that she only did what she did because she was unable to go against Clayman's orders. When Rimuru decided that Myulan needed to die, Youm frantically begs for her life to be spared, even fully prepared to be punished alongside her. [[spoiler:Fortunately, Rimuru doesn't actually kill Myulan and just intended to replace her bugged heart with a new one.]]
* AwesomeMomentOfCrowning: [[spoiler:He becomes the King of the Farmenas Kingdom, forged out of the destroyed remnants of the Kingdom of Falmuth after the "war" with Tempest.]]
* FaceOfAThug: His rough looks hide his good heart.
* FakeUltimateHero: Tempest gave him credit for killing the Orc Disaster despite not even being in Tempest during the attack. They do make sure to [[TookALevelInBadass train Youm up]] so he actually fits the part.
* FriendlyRivalry: He strikes up an InterspeciesFriendship with Grucius of the Beast Kingdom Yuurazania, with the two of them becoming sparring partners and rivals for the affection of Myulan.
* InterspeciesRomance: With Myulan, with him being an otherwise normal human warrior while she's a centuries-old Majin.
* MasterSwordsman: He was decent with a blade at first, but then he got lessons from Hakurou and truly became this.

[[folder:Myulan]]
!!!The Ring Finger
-> '''Voiced by:''' Creator/AtsumiTanezaki (Japanese), Creator/ColleenClinkenbeard (English)

One of the Five Fingers under Great Demon Lord Clayman, Myulan is a Majin that disguised herself as a human and went under the employ of Tempest to serve her master's ends. However, she started having doubts after witnessing Tempest's prosperity and falling in love with a human named Youm.
----
* BarrierMaiden: Alongside Shuna, it's her job to [[spoiler:preserve the souls of Tempest's fallen during the "war" with Falmuth with her magic long enough for Rimuru to ascend to True Demon Lord status and properly revive them.]]
* EasilyForgiven: When her role in [[spoiler:the Kingdom of Falmuth's attack on Tempest was discovered, Benimaru attempted to execute her on-the-spot. Even [[AllLovingHero Rimuru]] was enraged enough by her betrayal to consider killing her, though he ultimately spared her due to her having been Clayman's pawn and because Youm was in love with her]].
* FaceDeathWithDignity: When Rimuru decides that she needed to die because of her involvement on the attack on Tempest, she calmly accepts her fate. She simply confesses her love to Youm and told him to not be deceived by evil women again. [[spoiler:Fortunately, Rimuru has other plans for her.]]
* GameFace: Myulan normally looks like a beautiful young woman with green hair and blue eyes, but when she reveals her true Majin form she gets a ThirdEye, various tattoos, clawed hands, and fur growing on her body, [[CuteMonsterGirl albeit still beautiful in her own way]].
* LiteralChangeOfHeart: [[spoiler:Rimuru replaces the flawed, bugged heart Clayman used to keep tabs on her with a magical artificial heart, though by then Myulan already regretted her actions.]]
* PleaseKillMeIfItSatisfiesYou: Rimuru suspects that [[spoiler:Myulan was attempting to goad him into killing her in order to spare Youm and Grucius from being punished for protecting her. While he seriously considers doing so after seeing how many were killed, Great Sage informs him that Myulan's anti-magic barrier wasn't the primary cause of the Tempest citizens being weakened and Myulan herself reveals she was an unwilling pawn of Clayman, prompting him to pardon her]].
* ReallySevenHundredYearsOld: She literally is over seven hundred years old, making her romance with Youm a MayflyDecemberRomance.
* RegretfulTraitor: Though she was always a spy, Myulan isn't happy about helping [[spoiler:the Kingdom of Falmuth slaughter Tempest after staying there for a time and needs to be further blackmailed by Clayman to go through with it. In fact, after the whole debacle and Rimuru forgiving her part in it she becomes a staunch advocate of preventing such a thing from happening again.]]
* WasOnceAMan: She was once a relatively normal witch who lived about 300 years and was dying of old age when Clayman found her. When he offered her a new lease on life and she accepted, she transformed into a Majin but in exchange became bound to him by [Marionette Heart]. He noted that even if she did somehow remove the heart, she would just revert back to her old age and die shortly afterwards, and regardless, she wasn't nearly strong enough to defeat him in a straight fight anyways.
* WhatIsThisThingYouCallLove: Myulan admits in all her long life she's never experienced real love, which is why her feelings for Youm and his declaration of his own for her takes her by surprise so badly.

* NotSoStoic: The normally composed and suave Black Progenitor is left in shock and disbelief after properly introducing himself to Rimuru only to be asked confusedly who exactly he is.

* DaddysGirl: It's subtle, but Souka seems to hold a great affection for her father: She stayed by his side during the Orc trouble, she's the one to help him stand up after rescuing him after Gabiru's betrayal, and when she
* TheDutifulSon: She acted as this during her time as the captain of the guard, helping protect the temple
* {{Ninja}}: As a member of Souei's the Shadow Squad, she dresses like a [[HighlyVisibleNinja stereotypical anime ninja]] and practises the same stereotypical anime ninja tropes that Souei does.

* ShipTease: She has an obvious crush on Souei.

* BadassBaritone: In the dub.

* HiddenDepths: His POV sidestory reveals he's picked up Shogi and gives Ifrit a handicap.
* HumanityEnsues: [[spoiler:After figuring out how to disable Unlimited Imprisonment, Rimuru creates a duplicate body and sticks Veldora's soul inside of it. Veldora makes a few modifications -- turning the hair blond and making it taller and more muscular -- and then lets out an evil laugh while declaring his triumphant return and intent to annihilate any who oppose him.]]

* TakingTheHeat: He took the blame for Rimuru [[spoiler:massacring 20,000 Falmuth soldiers]] to preserve Rimuru's peaceful reputation in politics. Seeing as how Veldora is already seen as a [[TheDreaded dreaded]] BloodKnight, it's not like taking the blame really affects him.
* {{Tsundere}}: He's even called one by Rimuru when he denies something.

* ColorCodedForYourConvenience: As primordial demons, prior to being named by Rimuru they only had their signature colors to go by for names: Noir for Diablo, Violet for Ultima, Blanc for Testarossa, and Jaune for Carrera.

* CreepyGood: He is a demon, but he sides with Rimuru. When he was summoned by Rimuru, he was tasked in finding Razel and capture him alive, and follows his orders to the letter. He maintained this tendency in the OAD when Tiss was backed into a corner by a phantom, and summoned him. His only terms were to keep his existence a secret.

** It's later revealed that being a NobleDemon is actually an inherent aspect of his very soul, as the very few demons that align with his "black" color (he just isn't very interested in creating tons of demon descendants like other Primordials) also possess very noble qualities, such as Beretta holding genuine loyalty to Ramiris not out of strength, since his true summoner Rimuru is stronger, but out of close companionship with her. Guy is able to realize Diablo has thrown his lot in with Rimuru simply from noticing this second-handed from Beretta long before the two Primordials ever meet each other again face-to-face.
