All spoilers regarding the first four story arcs (volumes 1-20) are unmarked. Examples pertaining to the fifth story arc and Shin High School D×D can be spoiler tagged if necessary.
This page details the supporting characters affiliated with the Khaos Brigade in High School DXD.
Established by Ophis, the Khaos Brigade is headed by Katerea Leviathan, Creuserey Asmodeus, Shalba Beelzebub, and Rizevim Livan Lucifer, all of whom are descendants of the original Four Great Satans. The brigade intends to remove the Great Red, one of the most powerful Dragons in existence known as the True Dragon, from the Dimensional Gap. The brigade is also dissatisfied by the growing alliance of various mythological powers and seek to cause chaos in our world. Few people dared to challenge them, save for the current Four Great Satans and the alliance between the Angels, the Fallen Angels, and the Devils.
Following the deaths of Katerea in volume 3, Creuserey in volume 6, and Shalba in volume 12, the remnants of the Khaos Brigade reorganize into the Qlippoth Faction.
- Badass Army: They're one of the most feared and powerful armies in the Underworld and appropriately enough, they plan to spread chaos.
- The Dreaded: Their very presence struck fear across the underworld, but that all changed when the Three Factions formed The Alliance.
- Equal-Opportunity Evil: Gender and race are no issue for the brigade. Humans who are descendants of legendary heroes have appeared in several volumes.
- Evil Army: One of the first evil organizations introduced in the series to feature a large variety of villains in its roster. They have some of the strongest fighters in the Underworld and in the Hero Faction.
- Felony Misdemeanor: The Khaos Brigade commits terrorist attacks because the Three Factions are negotiating a peace treaty after years of conflict.
- The Man Behind the Man: The Khaos Brigade is the one behind the assault at Kuoh Academy's Peace Conference between the Three Factions and Diodora Astaroth's invasion of the Underworld.
- Mook Horror Show: What the Occult Research Club and The Alliance subject them to when they first encounter them. The Khaos Brigade uses everything they have at their disposal, even using Diodora to attack the underworld, kidnapping Yasaka and reviving the Evil Dragons, but they are quickly wiped out.
- Take Over the World: The Khaos Brigade's plan is to cause chaos everywhere and rule the Underworld.
- Well-Intentioned Extremist: The brigade is led by people who genuinely believe in its ideology, as radical as their methods may be.
Old Satan Faction
Old Satan Faction
A large faction of confederate Devils who remain loyal to the old devil practices. Similar to the Vali team, the Satan Faction acted as early enemies for Issei and company, but have gone quiet for the most part after Ajuka defeats most of their forces.
- Authority Equals Asskicking: Katerea, Creuserey and Shalba are the leaders of the faction and the most powerful.
- Best Served Cold: They've been planning to exact revenge on the Four Great Satans and all devils for years.
- Hypocrite: Despite touting Devils as the strongest beings who deserve control over the world, they rely heavily on the empowering snakes of Ophis, a dragon.
- Kill 'Em All: Katerea Leviathan's attack on Kuoh Academy in volume 4 resulted in her death at the hands of Azazel. Then, in volume 6, the Occult Research Club's rescue of Asia Argento and Creuserey Asmodeus's death ironically left only Shalba as the Sole Survivor of the attack. As of the end of volume 11, Rizevim, Vali and Ingvild are the only known remaining pure-blood descendants of the original Satans still alive and it would seem the species is on the verge of extinction. There's still continuation of the original Satans in Vali and Ingvild, but chances that any remaining pure-blooded descendants are going to be genetically thinned out later on. And with Rizevan having already passed away, Rizevim dying five months before the Azazel Cup and Vali considering fighting Better Than Sex, they're the only options available.
- The Resenter: The faction's leaders deeply resent the current Satans since they felt that they were defiling Satan's name.
- Sins of Our Fathers: They exact revenge on the Devils for what they did to their ancestors.
- Smug Snake: The descendants of the previous Satans hold themselves above the current "fake" Satans, but they each had to receive Ophis' blessing to even begin to pose a threat.
- The Unfettered: Katerea, Creusery and Shalba are willing to do whatever it takes to achieve their goals, even committing terrorist attacks on Kuoh Academy and the underworld.
- Visionary Villain: They have a clear vision where the descendants of the original Satans could rule the Underworld after spearheading an uprising against the Four Great Satans.
- Well-Intentioned Extremist: They want a world where the original Satans' descendants could rule the Underworld but it doesn't justify them using terrorist attacks.

- Roaring Rampage of Revenge: In Volume 11, he attempts to take revenge on Issei and the devils for defeating him by manipulate Leonardo into using his Balance Breaker. Then, he kidnaps Ophis and despite being killed by Issei, Shalba does succeed in getting revenge on Issei at the same time he is killed off.
- Sanity Slippage: He goes completely insane when he's defeated by Issei and restored by the Hero Faction.
- Shout-Out Theme Naming: Shalba's name is derived from Shagia Frost and Olba Frost, both from "After War Gundam X".
- Smug Snake: He is willing to flaunt his powers in front of everyone and keeps on declaring that he will make the other mythologies acknowledge that the devils are the strongest race in the entire world. And is even willing to kill children who do not agree with his ideologies. Three guesses what Issei did to him. Twice.
- Taking You with Me: Issei blasts Shalba into nothing, but Shalba returns the favor to him.
- Trauma Conga Line: Since his defeat in volume 6, Shalba's life has become one traumatic experience after another. He had his arms bitten off, blasted by Issei's Longinus Smasher and went insane after that. By volume 11, it's clear that he wants to exact revenge on the devils, specifically Issei.

- Would Hurt a Child: In Volume 11, he forces Leonardo to use his Balance Breaker and kidnaps Ophis in an effort to exact revenge on the devils. He also shows no discomfort about killing children, which understandably doesn't sit well with Issei, whom the children regard as a superhero.
- You Have Failed Me: In Volume 6, he kills Diodora after the latter fails to rape Asia and kill Rias' group.
- You Have Outlived Your Usefulness: He's willing to dispose of anyone whom he considers a liability to his plans. Just ask Diodora.
Hero FactionA dangerous faction consisting of human descendants of famous mythology characters led by Cao Cao. The heroes serve as the primary antagonists of the light novel's third saga; not only succeeding in draining Ophis of her power for the Khaos Brigade but forming an alliance with the Death God, Hades, to end the world of devils.
- Badass Normal: They're humans who could die right off the bat from just about anybody from any mythology. They still kick ass.
- Deadly Upgrade: Chaos Break, an injection that is capable of giving a massive power-up to humans at the cost of their bodies deteriorating to the point not even a phoenix tear can heal them.
- Deal with the Devil: Made a deal with Hades to acquire Samael, the Dragon Eater.
- Escaped from Hell: This is what Indra taunts Cao Cao, Georg, and Leonardo to pull off only because Issei already did it before. Cao Cao makes it out while Georg stays behind for the time being to study the realm of the dead with Leonardo keeping him company.
- Humans Are Bastards: Definitely fits within the core group members.
- Humans Are Special: The only ones who could wield a Sacred Gear (and not artificial ones) are humans or former humans who either turned into angels or devils. Unfortunately, the Hero Faction are the villains for the third arc.
- Knight Templar: They seem to genuinely believe that killing gods and monsters are for a good cause.
- Know When to Fold 'Em: When their plan to summon Great Red by capturing Yasaka is foiled by Issei and his friends, they wisely decide to retreat.
- Named After Somebody Famous: They're named after and are descended from famous mythological characters.
- Never My Fault: Whenever they're called out on their actions, or the consequences, they couldn't care less. Cao Cao is especially guilty of this.
- Put on a Bus: After the Hero Faction is defeated in Volume 12, Jeanne and Heracles are captured by the Devils and Fallen Angels for interrogation, never to be seen or mentioned again.
- Shown Their Work: In-universe at least.
- Undying Loyalty: When they're not Brainwashed and Crazy, Cao Cao's willing to let other Sacred Gear human users join him for his cause. They do follow him all the way through to the end as shown by the Mook Issei encountered.
- The Unfettered: Has been shown to go absurd lengths to accomplish their goals.
- Unwitting Pawn: They all get tricked by Hades.
- Weak, but Skilled: They're all this, but Cao Cao deserves a special mention because according to Vali, he could be the strongest human being thanks to his True Longinus.
- Well-Intentioned Extremist: The only reason why they even formed the group was because the humans are the ones who get affected the most when three factions who have been going on a war with each other for a long time suddenly had a Peace Conference and created The Alliance.
- What Measure Is a Mook?: Sends a lot of Mooks towards the Occult Research Club to force them to reach Balance Breaker levels.
Leader of the Hero Faction and a descendant of Cao Cao. He also wields the strongest Longinus, True Longinus.
- Affably Evil: He is friendly when fighting his enemies.
- An Arm and a Leg: Issei uses his Ascalon to deliberately chop of Cao Cao's left arm during their duel in Kyoto, but it's rendered moot when Cao Cao uses Phoenix Tears to reattach it.
- Authority Equals Asskicking: Being the leader of the Hero Faction, he can wipe the floor with relative ease.
- Awesomeness by Analysis: He beats his opponents by gathering intel on them and taking advantage of their weakpoints.
- Badass Normal: He's just a normal human being who has a Sacred Gear and almost always dominates in fights.
- Big Damn Heroes: In Volume 17, he breaks the barrier Qlippoth set up but doesn't show up personally. In the next volume though, he does this more traditionally by showing up to help battle the Evil Dragon Ladon.
- Blade on a Stick: The True Longinus (Also known as Holy Spear of the Setting Sun) is the original spear that stabbed Jesus!
- Blood Knight: Clearly enjoys fighting tough opponents like Issei, but is more composed than other examples. Issei even compares him to a calmer version of Vali. When one of the members of Khaos Brigade showed him of an alternate world at peace, he found it boring.
- Character Tics: He frequently taps his spear against his shoulder, a habit Issei takes note of.
- Combat Pragmatist: Encourages gathering information and fights extremely unfairly. Best exemplified during his fight with Vali and Issei's group. He used Samael's poison to take out Vali and attacks the weakest links of the group knowing that Issei would protect them which he did. He instantly got rid of the two fighters that actually was a threat to him and weakened the other side immensely.
- Expy: Other people in his group refer to him as the modern-day Cao Cao.
- Eyepatch of Power: He wears an eyepatch over his right eye after losing both his real eye and his Medusa eye to Issei. Even so, it doesn't slow him down.
- Eye Scream: Issei destroys one of Cao Cao's eyes, forcing him to use Medusa's eyes as a replacement. And then Issei destroys that one as well with Samael's blood.
- Foil: To Issei; both have companions who are willing to join the both of them, but while Issei, a devil, will not sacrifice anybody for his cause and does care for the well-being of other people, Cao Cao, a human, is willing to make sacrifices for his cause.
- Glass Cannon: All it takes to defeat him is just one hit from anybody in this series. Yet no one can land a hit on him.
- Glory Seeker: In addition to his Blood Knight tendencies, he wants to be remembered as a hero who accomplished mighty deeds, and thinks being named if not descended from an actual famous hero pretty much grants him the title as long as he performs "accomplishments," ie, significant military victories. He is suitably crushed when he's informed that the title of "hero" is not something you can give yourself, and even being from a proud heroic bloodline won't cut it. The society you live in has to judge your deeds heroic by its own standards.
- Handicapped Badass: Beginning with volume 11, Cao Cao remains much the skilled warrior he was before losing an eye to Issei in volume 9.
- HeelFace Turn: Of a sorts. He's quit the Khaos Brigade and gets permission to enter the Azazel Cup. However, he is now the Vanguard to Indra after Sun Wukong stepped down, and with Indra's nature, it's hard to pin if he will remain an ally. He even notes the irony of it.
- Heroic Wannabe: He will do anything, and we mean anything he thinks will grant him the title of "hero." He cares not one whit about the morality of his actions, and there doesn't exist a single crime he will shy away from. Even after he's informed that gaining the "Hero" title he so covets is impossible, due to his own actions being considered nothing but villainous, he isn't shaken for very long...
- Idiot Ball: He just had to hold it before Issei fires off that Switch Princess button, even noting that Issei was acting out of character.
- Magnetic Hero: Despite the fact that he'll employ brainwashing for the humans with Sacred Gears who aren't willing to join his cause, there are also people who are willing to join him because he's accepted them and will die for them.
- Red Right Hand: After he's blinded in his left eye during his first fight with Issei, Cao Cao uses Medusa's eye. When that eye gets destroyed, he resorts to using an Eyepatch of Power.
- Superpower Lottery: He won it by being the current wielder of the strongest Longinus.
- Sphere of Power: The True Longinus' Balance Breaker, Polar Night Longinus Chakra Valdine has SEVEN of them, each with a different power and name.
- This Cannot Be!: After True Longinus refuses to activate its Truth Idea towards Issei.
- Villain Ball: He essentially defeated Issei and his friends twice in Volumes 9 and 11, then refrained from finishing them off so they can get stronger. Vali points out how foolish this was when Issei finally beats him in Volume 12.
- Worthy Opponent: He praises both Issei and Kiba for being able to at least match him and tells the both of them to get stronger. He also thinks of Vali as such as well because the last time they fought, it was exhilarating.
Voiced by: Sho Nogami (Japanese) and Robby Gemaehlich (English)
- Alternate Dimension: Capable of sending people to other dimensions.
- Insult Backfire: In the worst possible way. He tried to demoralize Gasper by insulting Issei's noble sacrifice to save Ophis. This backfires, spectacularly.
- Mysterious Mist: Dimension Lost (Also known as Fog of Extinction) creates mist to send attacks and anything to an Alternate Dimension.
- Specs of Awesome: Shown in volume 12.
- Super Power Lottery: Dimension Lost is one of the 4 top Longinus for a reason.
Voiced by: Jun Fukushima (Japanese) and Justin Briner (English)
One of the top two swordsmen of the Khaos Brigade faction (the other is Arthur). His Sacred Gear is "Twice Critical", the same Sacred Gear Raynare thought that Issei had.
- Artificial Human: Made from different patterns of genetics of those who carried the blood of the original Siegfried to use Gram.
- Blessed with Suck: Rather badly too. His Sacred Gear is Twice Critical which comes from dragons while Gram is a dragon killer. You can see where this is going if he tries combining the two.
- Dual Wielding: Triple wielding, all the way to sextuplet wielding.
- Impaled with Extreme Prejudice: Kiba skewers him with Gram and Ascalon.
- Long-Lost Relative: Made by the Sigurd Institution the same as Freed and Lint, so he is artificially related to them.
- Master Swordsman: Took on both Kiba and Xenovia and won when they fought the first time.
- Mythology Gag: Lore-wise. He wields Sigurd's original sword, Gram, as well as its derivatives (Balmung and Nothung, which are treated in-universe as different swords than Gram). He also wields Tyrfing and Dáinsleif, which in the original myths have similar characteristics.
- Red Baron: "Chaos Edge" Sieg.
- This Cannot Be!: When Gram chooses Kiba as its master instead of him.
- We Can Rule Together: Offers Ajuka to fight against Sirzechs since he's the only one who could put up a fight with the latter. His answer? Wipe out all the devils that were present without even standing up.
Voiced by: Ayaka Asai (Japanese) and Amber Lee Connors (English)
A human being who inherited the spirit of Joan of Arc and is also the wielder of the Sacred Gear, Blade Blacksmith which is a holy sword version of Kiba's Sword Birth.
- Deadly Upgrade: Injected herself with two Chaos Breaks when injecting with one was already deadly to begin with. She still gets curb stomped by Issei who at this point doesn't even have his Evil Pieces inside of him.
- Instant Awesome: Just Add Dragons!: Her Balance Breaker allows her to summon a dragon made up of swords.
Voiced by: Jun Kasama (Japanese) and Chris Guerrero (English)
A human being who also has embodied the spirit of the hero, Heracles.
- Honor Before Reason: He threw away his Chaos Break injection at the last minute and decided to take on Sairaorg man-to-man. Needless to say, it doesn't work although Sairaorg was impressed with him.
- I Shall Taunt You: The reason why he and Saji fought in Volume 12.
- Kick Them While They Are Down: Stomps Sona on the ground when she and her group were trying to defend a bus full of kids.
- Projectile Spell: His Balance Breaker, Detonation Mighty Comet, makes him fire magic missiles at his opponents.
- Stuff Blowing Up: His Sacred Gear, Variant Detonation, creates explosions on anything he comes into contact with usually by punching.
Voiced by: Airi Otsu (Japanese) and Dallas Reid (English)
A boy who also has possession of the Longinus, Annihilation Maker and is also a descendant of Leonardo da Vinci.
- Brainwashed and Crazy: Shalba brainwashes Leonardo so that the latter can activate his Balance Breaker.
- Child Soldier: He's noted to be a pre-teen, yet the "hero" faction of Chaos Brigade brings him to the front lines, and Cao Cao doesn't even show any concern when he learns about Shalba's actions.
- Distressed Dude: Gets captured by a newly rebuilt Shalba Beelzebub.
- Mook Maker: Annihilation Marker (Also known as Creation of the Demonic Beast) can make monsters based on the user's imagination.
- Shout-Out: The monsters he summoned in volume 11 were called Bandersnatch and Jabberwocky.
- Summon Magic: Annihilation Maker is able to summon the monsters made by the user.
- Super Power Lottery: When you think about it the ability to summon a creature that can kill a god is pretty amazing.
A faction of mages who were expelled by the Magician's Council, and allied themselves with the Khaos Brigade. They are introduced attacking the peace conference in Volume 4, but aren't seen again until post Volume 12 under the title, "Hexennacht," and fight alongside the newly established Qlippoth faction.
A powerful mage who has possession of the Longinus, Incinerate Anthem. She is introduced in Volume 17 battling alongside Qlippoth's Evil Dragons against Issei and company.

- Dirty Coward: She will bail on the fight if she doesn't have a distinct advantage.
- Holy Hand Grenade: Her sacred gear is imbued with holy energy, much to the chagrin of the DxD group.
- Lured into a Trap: In Volume 19, she tries, once again, to interrupt a battle that was on the verge of concluding between team DxD and the rebel exorcists. Only this time, Rossweisse and Tobio Ikuse (Slash Dog) had prepared the proper counter behind-the-scenes for Walburga's infiltration by blocking off her means of escaping the battleground barrier. No longer able to teleport away, she is finally defeated through the combined efforts of Issei and Xenovia, and is later sent to Hell for interrogation.
- Playing with Fire: Basically a fire-mage thanks to her Longinus, Incinerate Anthem (Also known as Chief Mourners Crucified Stand of Purple Flame).
- Purple Is Powerful: A powerful mage who wears a purple Gothic Lolita outfit and her Longinus' flames are purple.
- Sex Is Violence: She enjoys fighting her enemies a little too much...
- Soul-Powered Engine: The sub-species Balance Breaker of Incinerate Anthem, Incinerate Antiphona Calvario used half of Yamata-no-Orochi's soul to recreate, out of purple flames, the evil dragon tied to a large cross.
- Technicolour Fire: Incinerate Anthem's flames are purple.
- Teleport Spam: One of her abilities powerful enough to which even a post-Volume 16 Gasper can't keep up with.
The deaths of Katarea Leviathan, Creuserey Asmodeus, and Shalba Beelzebub — as well as the treachery of the Hero Faction — reduced the Khaos Brigade to a mere fraction of its former self. This remnant faction retreated with the last Old Satan Faction leader Rizevim Livan Lucifer and rebuilt themselves, becoming the Qlippoth Faction. Their goals are to revive the Evil Dragons in an attempt to bypass the Dimensional Gap and invade other worlds, including our own.
The brother of Grayfia Lucifuge, he first appears in volume 14, giving back Issei the three first-years who were kidnapped during the events just so he can study their fighting prowess.
- Ambiguous Disorder: He has an unsettling obsession with his older sister Grayfia, believing that the only reason she values Sirzechs over him is a preference of the color red (hence his fake Boosted Gear) rather than him joining a terrorist brigade. He also becomes fixated on Rossweisse because he believes that she resembles Grayfia, even though their only similarity is silver hair.
- Aristocrats Are Evil: He plays this completely straight to use as a justification for destroying Sona's Ratings Game training school with parents and children inside, by self-destructing some of his own magician minions.
- Euclid: "It's okay, right? High-Class devils weren't going to attend or send their children there anyway."
- Armor-Piercing Question: He asks both Issei and Sirzechs one question: "What is a devil?" While Issei didn't have an answer to his question, he did note that Euclid's just insane.
- Awesomeness by Analysis: By using the power of the Holy Grail he was able to create a replica of Issei's Boosted Gear from the information he collected of Ddraig's soul and the Sacred Gear from Issei's original body left in the Dimensional Gap.
- Cain and Abel: He's the younger Cain to Grayfia's older Abel.
- Chekhov's Gunman: He's mentioned during the time when Grayfia mentions her family to Issei during her In Vino Veritas moment.
- The Comically Serious: He can make comments about Ddraig's state with a straight face.
- The Dragon: He acts as one to Rizevim, especially after he leaves the Khaos Brigade.
- Evil Cannot Comprehend Good: He does not understand why Grayfia doesn't like his behavior. He ultimately thinks it's simply his choice of wardrobe or color.
- Euclid: "Why? Why do you reject me? I'm now also 'red.'"
- Evil Knockoff: He created his own artificial Boosted Gear using a fraction of Issei's previous body that was killed by Samael's poison and the Holy Grail. Though he can only use the basic abilities and the Scale Mail, he's still a match for Issei since his base stats before boosting are higher than Issei's.
- Yandere: Euclid is very obsessed at Grayfia, who as it turned out, is his own sister. It also extends to Rossweisse due to her reminding him of Grayfia.
Rizevim Livan Lucifer
The son of the original Lucifer and Lilith and grandfather of Vali Lucifer, Rizevim is a devil who is the leader of the Qlippoth Faction. Not only that, but he has a penchant for tormenting everyone he comes across.
- 0% Approval Rating: More than anything else, this is the reason he meets his end in volume 20. Despite spending his entire existence going out of his way to offend and torment everyone he comes across, he is utterly shocked and dismayed that nobody, not even the evil dragons with whom he partnered, would lift a finger to help him.
- Abusive Parent: He happily admits brutalizing Vali's father, Rizevan, and ordering the guy to do the same to Vali. He then laughs while admitting that he killed his own son for being scared of Vali's retaliation. What's worse is that in Volume 21 and 22, it's revealed that Rizevim used Vali's mother as a hostage so that Vali would allow himself to be abused without resistance, and Vali's father would comply with the abuse. If either of them refused, she would be brutalized instead, and being a far more fragile ordinary human, the results are easy to imagine.
- Arch-Enemy: He serves as this for Vali, since Rizevim was the one who brutalized Rizevan, who in turn did the same thing to Vali himself.
- An Arm and a Leg: An enraged Fafnir bites off an arm, but he reattaches it shortly afterwards. Later, Vali chops off his arm after Issei defeats him.
- Authority Equals Asskicking: He's the leader of the Qlippoth Faction and one of the most powerful devils.
- Back for the Dead: For his grand importance in Volumes 18 and 19, the most that he does in volume 20 is to be soundly defeated by Issei and Vali, and being Eaten Alive by Fafnir.
- Badass in Charge: The leader of the Qlippoth Faction.
- Beard of Evil: He has a goatee which matches his evil personality.
- Big Bad: Rizevim is the main antagonist of the fourth story saga, with his goal of reviving Trihexa causing him to come into conflict with the main characters.
- The Bully: Arguably of the very worst kind. If you're stuck in his sphere of influence, can't run away, and can't fight back, he will brutally torment you to death. Just ask Rizevan Lucifer, Vali's father. If you are strong enough to be a threat, he will either send minions at you, or show up himself, cause as much damage, pain, and suffering as he can, and then run away laughing to somewhere you can't reach just so he can savor your impotent rage.
- Cloud Cuckoolander: He's kind of... off. It's hard to tell if he's doing it on purpose or not, but either way he does a good job at pissing people off.
- Cruel and Unusual Death: Being eaten alive in half by a dragon isn't a pleasant thought.
- Dead Man Switch: He knows that all of his Kick the Dog For the Evulz actions have earned him a fair amount of enemies who want him dead (even though he's ultimately killed by someone he didn't expect), so he set things up so that, in the event of his death, his soul will be used to unseal Trihexa.
- Did You Just Flip Off Cthulhu?: He slaps Asia in front of Fafnir and captures Issei's parents... and eventually gets killed for it.
- Dirty Coward: He's a devil who won't show any mercy. However, he resorts to uses cheap tactics and pulls a Villain: Exit, Stage Left once he's overpowered to save himself.
- Disc-One Final Boss: He may have been defeated by Issei and Vali, and Eaten Alive by Fafnir. But all there is left in the fourth arc are Trihexa, Apophis and Ai Dahāka.
- Do Not Taunt Cthulhu: After slapping Asia in front of Fafnir and capturing Issei's parents just to spite him, he ends up on the receiving end of Vali and Issei's attacks before he gets Eaten Alive by Fafnir.
- Eaten Alive: His fate, when he gets curb-stomped by Vali and Issei, and Fafnir traps him in his mouth.
- Even Bad Men Love Their Mamas: He named Ophis' spawn Lilith after his mother. He also had the means to asexually produce Pure Devils using what remains of his mother's flesh, but didn't take the opportunity because it would further rot her.
- Evil Cannot Comprehend Good: He's completely unable to understand how Issei's parents could still accept him, even after he's been turned into a dragon and when he enters Villainous Breakdown mode, he desperately tries to plead for his life after being defeated by Issei.
- Evil Gloating: He loves to gloat about his plans and what he did, especially to Vali and Issei.
- Evil Laugh: He cackles "Uhyahyahyahya!" when he runs away or when he commits evil deeds.
- Exit, Pursued by a Bear: Or "Exit, Pursued by a Dragon". He gets eaten by Fafnir, one of the dragons that he didn't take seriously enough.
- Famous Last Words: Rizevim yells "Damn it!" before he gets Eaten Alive by Fafnir for a Half the Man He Used to Be death.
- Fatal Flaw: He is repeatedly warned that he doesn't take Dragons seriously enough, something that even the Biblical God wouldn't do, and ultimately gets beaten down by Issei combining the power of two legendary dragons, then killed by one while two that were supposed to be his subordinates ditch him and take over his plans.
- Faux Affably Evil: He has a tendency to be charming and friendly in spite of his true colors.
- Foreshadowing: There's a damn good reason why Sirzechs' group does not have any Sacred Gear users.
- For the Evulz: In Volume 18, he chose to attack Heaven despite already acquiring the items he needs for his grand plan.
- This trope is pretty much his entire motivation for everything he does. He believes that Devils are supposed to cause trouble wherever they go, and admits to setting out on his plans simply because he had nothing else to do with his long life. Each time he shows up, you can be sure that he's going to Kick the Dog with a harder kick than the last time he did so. No act is off limits to him: turning the vampires who cooperated them into Evil Dragons and using them to ravage vampire society, ordering attacks in broad daylight, at a school, or even in the middle another battle, kidnapping Issei's parents and forcing him to transform into dragonic form in front of them, using his soul to unseal Trihexa, and setting up the potential for interdimensional war so that even if Trihexa is resealed, the good guys still have his mess to clean up.
- Half the Man He Used to Be: How he meets his end at the jaws of Fafnir.
- Humiliation Conga: Volume 20 is just one long string of events for things to finally catch up to him, in addition to him suffering a Rasputinian Death. In order: Issei finally defeats him with his shiny power up, Lilith pulls off a HeelFace Turn after both Vali and Azazel convince her to come with them for her to meet up with Issei, Ophis and Great Red, Vali finally gets to cut off his arm because Rizevim's too weakened to nullify his Sacred Gear, Apophis and Ai Dahāka pretty much tell him that he sucks, and finally Fafnir crushes his legs before he is Eaten Alive for good. He still manages to get the last laugh after all that, because his soul was used to awake Trihexa.
- I Shall Taunt You: He often uses intimidation, threats and taunting to weaken his enemies.
- Karma Houdini Warranty: He finally gets his comeuppance at the end of volume 20.
- Kick the Dog: Every deed that he does is to prove how evil he is.
- Last of His Kind: As of volume 11, Rizevim seems to be the only remaining leader of the Old Satan Faction left and one of the only members of the original pure-blood descendants of Satan left after his son died. After volume 20, Rizevim is dead, leaving only Vali.
- My Death Is Just the Beginning: Unfortunately for the heroes, he prepared to forcefully remove Trihexa's seals if he were defeated by using his soul as the key.
- No-Sell: He is completely immune to Sacred Gears, including attacks amplified by them.
- Obviously Evil: The intimidating presence, his devil powers and Evil Laugh indicate that he is definitely not a good guy.
- Offing the Offspring: He killed Rizevan for being scared of his grandson's retaliation.
- Power Nullifier: Sacred Gears are useless against him.
- Properly Paranoid: Rizevim was scared of Vali retaliating against him, so he killed Rizevan. His fear ultimately turns out to be proven right when Vali chased after him and cut his arm off.
- Psychopathic Manchild: His general demeanor is comparable to a schoolyard bully.
- Rasputinian Death: Rizevim gets one of the most brutal deaths in the series. First, he gets easily defeated by Issei's Diabolos Dragon, then Vali chops of his arm, then gets his legs stepped on by Fafnir and is eventually Eaten Alive by the latter.
- The Remnant: He's a former member of the Khaos Brigade.
- Smug Snake: He's a normally competent devil, but he fatally underestimates the Dragons.
- The Sociopath: His actions towards Vali and Issei clearly shows his status as a high-functioning sociopath.
- So Long, Suckers!: He often taunts his enemies in this manner whenever he feels that he's outmatched.
- Strong Family Resemblance: He's essentially a middle-aged Vali with a goatee.
- Stupid Evil: Subverted. He spends his entire existence so fixated on proving himself "the most evil devil ever," even boasting of being a devil that led a successful raid on Heaven, that he's constantly derailing his own plans and endangering his minions through completely pointless cruelty and sadism. However, he knew it would eventually get him killed when he fucked himself over, so he set up a failsafe in Agares where his soul would unlock Trixeha, just so he could laugh at all the suffering he's caused from beyond the grave.
- Superpower Lottery: No Selling Sacred Gear abilities. And that's not even his true powers yet.
- Underestimating Badassery: Even though he's one of the most powerful leaders of the Old Satan Faction, he really should have taken Dragons a little more seriously. Especially when Issei beats him in battle.
- Undignified Death: He gets crushed and Eaten Alive by Fafnir and can only scream in damnation as he dies.
- Villain: Exit, Stage Left: Whenever Rizevim gets overpowered and loses, he ends up pulling a quick escape.
- Villainous Breakdown: Between Fafnir haunting his dreams, his attempt to break Issei in front of his parents going nowhere, trying and failing to kill them as well when they still show affection for their son, and Issei severely injuring him with a new power up, Rizevim loses it when he's cornered by Issei and Vali.
- Villains Want Mercy: Spent the entirety of his appearance in Volume 20 bouncing back and forth between begging for his life and screaming profanity at the protagonists when it looked like they wouldn't oblige, when he wasn't too busy being smug about brutalizing the friends and family of the protagonists and threatening them.
- War for Fun and Profit: He didn't even need to unseal Trihexa. Volume 21 reveals, after Apophis is defeated, that Rizevim had been using Agares to open teleportation portals to other worlds and dimensions while bypassing the dimension gap entirely, openly declaring war on the residents, and leaving instructions so that they could do the same and teleport to Earth's mythologies, scared, hurt, and angry. It is even compared in-universe to internet trolling on social media, but on a planetary scale.
- White Hair, Black Heart: He has silver hair... and acts as the Big Bad for the fourth story saga.
- Would Hurt a Child: He personally brutalized his son and Vali, and laughed about it.
- You Have Got to Be Kidding Me!: He says the trope name word-for-word when he realizes his fate the moment Fafnir emerges from the Dragon Gate.
- Younger Than They Look: For this series anyway. He is Vali's grandfather and he does look like his age, but he's younger than Azazel. Justified in that Devils can magically change their appearance.
The mascot of Qlippoth.
- Clone Jesus: Lilith is a clone created from the power the Khaos Brigade stole from Ophis. Most people outside the Khaos Brigade think she actually is Ophis due to having to hide the fact Ophis is now living in the Hyoudou Household.
- Dead Guy Junior: Named after Rizevim's mother, Lilith, the mother of all demons in Judeo-Christian mythology.
- HeelFace Turn: She abandons Rizevim after Azazel and Vali convince her to meet up with Issei, Ophis, and Great Red... and offer her chocolate.
- Only Known by Their Nickname: After her HeelFace Turn, similar to how Ophis is known to some by the name "Phis" to avoid people knowing who she is, Lilith is called "Leece" in the same manner.
- Sweet Tooth: Azazel tempts her out of serving Rizevim with some chocolate. This trait was passed down from Ophis.
- Third-Person Person: When she does talk she will refer to herself this way.
- The Quiet One: She rarely talks, and then only in very short sentences.
- Walking Spoiler: Knowing about Lilith's story gives away a big plot-twist that occurs during Issei and company's war against the Hero Faction.
