- Adaptational Heroism: While certainly a flawed person with her workaholic nature, she is also a good person who deeply loves her children, and she has a genuine desire to help preserve the world's Pokémon, a far cry from the cold and disturbed woman she was in the games.
- Adaptation Personality Change: Lusamine is quite the opposite of the cold, controlling mother she was to Lillie in the games, instead being an overly-affectionate womanchild, with Lillie being unafraid to visually and vocally show her exasperation toward her. As for her obsession with Ultra Beasts, while still a source of tension between her and her kids, it's not nearly as sinister and is presented as more of a distraction from her family. However, when one does show up, she can't help flash a blank smile amidst a problematic situation.
- Adaptational Wimp: A trade of the above is that, compared to her game counterpart, she's decidedly less aware of the things going on in her own facility with Faba and unable to hold her own in a battle, at least against Ultra Beasts like Nihilego. On the other hand, fusing with Nihilego not only gives her Pokémon a big power boost, but she also personally attacks Ash and his friends rather than simply let her Pokémon do all the fighting in the game.
- Adapted Out: Due to there already being a recurring Bewear, she instead has an Absol and a Salazzle, two Pokemon that she didn't have in the games. Since Bewear was her ace Pokémon, the role shifted instead to her Clefable.
- Amazingly Embarrassing Parents: Not above giving her own daughter a noogie. In fact, her affection crosses the line to Lillie, much to her dismay.
- Be Careful What You Wish For: In SM050, she finally gets her wish of meeting an Ultra Beast for herself...by being kidnapped by Nihilego and later fusing with it.
- Believing Their Own Lies: At least when it comes to her daughter, Lusamine tends to get a few details wrong about their relationship. For instance, she credits herself for enrolling Lillie into Pokémon School, even though this was entirely Lillie's decision.
- Big Good: As the boss of the Ultra Guardians.
- Brainwashed and Crazy: In this continuity, she's a (mostly) unwilling victim of Nihilego's mind control.
- Dark Is Not Evil: She owns a Poison-type Salazzle, a Ghost-type Mismagius, and a Dark-type Absol, yet she is a downright nice person. Played with when she fuses with Nihilego, turning her blonde hair dark indigo and brainwashing those very Pokémon, all of whom aren't afraid to hurt Ash and her children when they get in her way.
- Dishing Out Dirt: After fusing with Nihilego, who is a Rock-type, she gains the ability to manipulate the rocks and land itself in the Ultra Deep Sea.
- Early-Bird Cameo: Like Gladion, she appears in the family portrait in Lillie's house long before her debut.
- Fiction 500: She basically turns the Pokémon School building into an Elaborate Underground Base with overly-fancy entrance and exit on an idle whim.
- Genius Ditz: She's a highly intelligent scientist and businesswoman despite acting like a flaky Woman Child half the time.
- Glamorous Single Mother: Subverted; although she provides her children with a wealthy lifestyle, her job gets in the way of her being a proper mother.
- Goal in Life: Lusamine's dream is to one day encounter an Ultra Beast for herself. However, she eventually realizes that this obsession is getting in the way of her family life, and is completely turned on its head when it makes her easily fall under Nihilego's control.
- Innocently Insensitive: She clearly has no malicious intent with teasing Lillie, but she fails to realize how demeaning this is to her.
- Jerkass Realization: She realizes how far she has put her work over her children when Gladion calls her out on it and reveals the truth about what happened to Lillie that made her unable to touch Pokémon, something she was always too busy to notice or even question for years.
- Late-Arrival Spoiler: She's Lillie and Gladion's mom, which was a massive spoiler in the original game.
- Locked Out of the Loop: To the fact that Faba had summoned an Ultra Beast and caused Lillie's trauma.
- Mama Bear: Once she learns the truth about what Faba's been up to and realizes that her carelessness led to Lillie becoming afraid of Pokémon, she becomes this towards her children.
- More Than Mind Control: While Nihilego controls her to some extent, it also takes advantage of her innermost feelings, namely her lifelong desire to finally meet an Ultra Beast, which it exploits so that Lusamine refuses to leave with her children.
- Ms. Fanservice: A few flashback scenes of her in a bikini show that She's Got Legs.
- My God, What Have I Done?: This is how she reacts when Gladion calls her out for failing to notice the reason Lillie couldn't touch Pokémon was because she was left traumatized by an Ultra Beast that Faba summoned, one of the very creatures Lusamine sacrificed much of her family life to study. While it's suggested that Faba told her a cover story, the fact she bought into it without question only makes her feel worse.
- No Pronunciation Guide: The English dub pronounces her name as "Loo-suh-meen" instead of the Japanese "Loo-suh-mee-nay".
- Not So Different: Rotom Dex notes that when she and her daughter clash over any given issue, they're more alike than they are different, which is opposite of how it regularly seems between them.
- Older Than They Look: She's a little over 40 based on info from the games, but looks (and acts) much younger.
- Parental Neglect: Although she adores Lillie and used to spend a good deal of time with her children, her obsession with studying the Ultra Beasts and her tendency to take business calls over actually setting aside some quality time has since put a serious strain on her relationship with Lillie (not including her penchant for embarrassing her daughter in front of her friends). Sadly, Lusamine fails to realize just how serious of a problem this is until Gladion finally chews her out for it.
- Poisonous Person: She turns into one while fused with Nihilego, who's part Poison-type, giving her the power to generate an entire lake of toxic liquid.
- Psychopathic Womanchild: Fusing with Nihilego takes a heavy hit to her sanity, but Gladion explains that half of her rambling is obviously stemming from her childhood dream to meet Ultra Beasts, which explains her behaving like an oversized toddler who thinks that the kids are there to take away her "toys". It's even more pronounced in the Japanese dub, where she outright talks like a young girl when possessed.
- Reasonable Authority Figure: When she offers to take Nebby off Ash's hands, as the Aether Foundation would be better equipped to research and care for it, Ash refuses on the grounds that Solgaleo and Lunala made him promise to keep it safe. Rather than press the issue, she accepts his reasoning and only asks that he call if he needs anything.
- Red Herring: Unlike the games, turns out she had nothing to do with Lillie's trauma here.
- Strong Family Resemblance: The resemblance to her children, particularly Lillie, is lampshaded by the RotomDex. She looked even more like Lillie in her younger years◊.
- Taking the Bullet: When a Nihilego attempts to abduct Lillie, Lusamine throws herself between it and Lillie. When she realizes that it is about to abduct Gladion instead, she moves and shields him from Nihilego, letting herself be abducted instead.
- Tears of Joy: When Lillie is able to touch Pokémon again, for the second time.
- Took a Level in Badass: Her and her Pokémon when the former is fused with Nihilego, which in turn gives her Pokémon Beast Boosts.
- Wacky Parent, Serious Child: Her dynamic with Lillie and Gladion has shades of this.
- Womanchild: She's in her 40s, but acts more childish than her roughly 10-year-old daughter. This takes a dark turn when she fuses with Nihilego. Her reason for the overdone Sentai-esque stuff during the UB arc? She just thought it'd be "cool". Ash is the only one to not find the aesthetic choices embarrassing.
- Workaholic: Part of the reason Lillie has a strained relationship with her is that her job makes her constantly busy.
- Adaptational Badass: Played with. While his personality remains over the top and goofy as ever, his Pokemon team is very effective and he's a competent battler. Hypno and Alakazam make short work of both Gladion and Ash. He also makes it to the Top 16 of the Alola League.
- Adaptational Heroism: While in Ultra Sun & Moon he sold Lusamine out to Team Rainbow Rocket, here he remains on the heroes' side, even teaming up with Kukui to battle Team Rocket. He is also loyal to Lusamine and her family on a much more personal level than in the games, particularly after they gave him a second chance after he'd caused them such harm.
- Adaptational Villainy: He wasn't a good guy, to begin with, but he's much worse here, going so far as to try to abduct Lillie and erase her memories to save his reputation. That said, he also apologizes for his actions when the consequences of them go farther than he ever wanted.
- Amusing Injuries: In SM046, Faba gets decked in the face by an escaping Ditto.
- Arc Villain: He's the main villain of the Cosmog arc.
- The Atoner: This version of Faba has sincere regret for his villainous actions and works to make up for them.
- Big Bad Wannabe: He schemes behind Lusamine's back to gain access to the Ultra Beasts. When he finally brings forth Nilhilego from Ultra Space, however, it nonchalantly smacks him aside.
- Cheaters Never Prosper: He practically gets his own ass handed to him for having Hypno use Psychic to send out Ash's Meltan specifically, not taking into consideration that the thing shown to be eating metal would go for Hypno's steel pendulum.
- Child Hater: Faba doesn't like kids, and he doesn't like having to visit the Pokémon school for this reason, although it changes after his HeelFace Turn when he appears to be enthusiastic about interacting with the kids in SM083.
- Closet Geek: Revealed in SM090 to be a fan of the Masked Royal when he recognizes the Malicious Moonsault Kukui and Incineroar use in battle.
- Composite Character: He takes on some of Lusamine's traits from the games, such as being the one to kidnap Nebby and use it to open an Ultra Wormhole.
- Crippling Overspecialization: His only Pokémon are Alakazam and Hypno. If both are defeated, then he's out of options fairly quickly.
- Easily Forgiven: He keeps his job (though demoted to work under Wicke, like in Ultra Sun and Moon), and attends Kukui and Burnet's wedding along with Lusamine and Wicke. He seems to be aware of this trope in action, as for the rest of the show he works sincerely hard at being worthy of that forgiveness.
- Hate Sink: Faba is responsible for Lillie's fear of touching Pokemon, mind-wipes Lillie's memories, and attempting to use Cosmog to summon Nihilego, only for the Nihilego to knock him aside and attack, resulting in Lusamine sacrificing herself to save her kids. Faba exists largely to be an utter Jerkass of a villain, even compared to the more sympathetic villains Team Rocket and Team Skull, although he gets somewhat better after his demotion as seen below.
- HeelFace Turn: Seems to have an honest change of heart after being demoted for his actions, and attends his coworker's wedding.
- Hoist by His Own Petard: In his Manalo Conference battle against Ash, he uses Hypno to force Ash into sending out Meltan, which he perceived as the "weak link" of Ash's team. Not only do Ash and Meltan easily defeat Hypno, but Faba doesn't even get to use an attack.
- More comedically, in SM114 he gets caught in his own sticky trap while demonstrating it to the Ultra Guardians.
- Jerkass: He throws Ash's Rowlet when he accidentally grabbed it instead of Nebby (though Ash did manage to catch it before it hit the floor). This understandably angers both Ash and Lillie. He's also the instigator of the whole incident that made Lillie unable to touch Pokemon, later resorting to abducting Lillie and trying to erase her memories to cover his tracks.
- Jerk with a Heart of Gold: Following Character Development. Most notable is his enthusiastic love for the Masked Royal and his increased loyalty to the Aether Foundation family, with him being brought to tears over the memory of Mohn, and the outcome of Lillie and Gladion's battle in the Alola League.
- Knight of Cerebus: Downplayed. While Faba's personality is pretty clownish by default, unlike the ineffectual Team Skull and Team Rocket, he is far more dangerous and the consequences of his scheming are played to much more devastating effect.
- Laser-Guided Karma: Just like in the games, his actions result in him getting demoted to rank-and-file.
- Mad Scientist: He created Type: Null/Silvally, a chimera. SM083 centers around another invention of his, a shrinking machine, malfunctioning.
- Manipulative Bastard: Covered his tracks after his disastrous first communication with Ultra Space led to Lillie getting attacked and traumatized by an invading Nilhilego, blaming the incident on Type: Null. Lusamine and even Gladion seem genuinely surprised he lied his way out for so many years.
- My God, What Have I Done?: He is horrified when Lusamine is abducted by Nihilego because of his actions. At first he attempts to deflect blame, but upon being demoted finally concedes that it was all his fault and humbles himself by asking for forgiveness.
- Nice Job Fixing It, Villain!: Ironically, his attempts to keep Lillie's mind wiped of the past result in her reuniting with Silvally and her phobia and Trauma-Induced Amnesia being cured.
- Never My Fault: When called out by Burnet for opening an Ultra Wormhole, he says it's not his fault and attempts to shift the blame to Lusamine. Though he's not entirely wrong, as the whole reason he did it was to impress her.
- Not-So-Harmless Villain: Faba for the large part acts like a temperamental Glory Hound and is almost as buffoonish as the Team Rocket trio. His Pokemon team, however, are incredibly powerful and dangerous, easily neutralizing Ash's Pikachu and Gladion's standard team, requiring Silvally to stop them from mind-wiping Lillie.
- Psychic Powers: He specializes in Psychic-type Pokémon, owning both a Hypno and an Alakazam.
- Red Oni, Blue Oni: He expresses annoyance with practically everything, contrasting Wicke's boundless optimism about even the most nightmarish of things.
- Reformed, but Not Tamed: Though he does try to atone in many situations for his past crimes, his ego and sneakiness remain. He also sometimes flubs at doing "good deeds", such as his well meaning but ill conceived team up with James to preserve the Masked Royal's identity from an "imposter".
- Small Name, Big Ego: He's incredibly arrogant and prideful but his plans usually end up backfiring on him and his ego is forcibly put in check.
- The Knights Who Say "Squee!": After figuring that Kukui is the Masked Royal, he reveals that he's a huge fan and shows Kukui his Masked Royal T-shirt.
- The One Guy: Among the group of Lusamine, Wicke, Professor Burnet, and himself, he is the only male.
- Underestimating Badassery: He uses Hypno to forcibly send out Meltan during his match with Ash in the Alola League, assuming Meltan to be the weakest of his team. He falls victim to a quick Curbstomp Battle after Meltan eats Hypno's pendulum.
- Would Hurt a Child: Sics his Pokemon on Ash and has them try to wipe Lillie's memories when he realizes They Know Too Much.
- Christmas Cake: Implied, despite all her talk of romance — she's part of the group participating in the bouquet toss at Kukui and Burnet's wedding.
- Nice Job Breaking It, Hero!: She had good intentions bringing an injured wild Stufful to Aether Paradise, but she also unintentionally separated it from the mother Bewear. The cast is lucky the Pokemon was just glad to have her cub back.
- Red Oni, Blue Oni: She sees everything as "romantic", regardless of how terrifying they might be. This contrasts with Faba, who sees everything with clinical detachment or outright annoyance.
- Attention Whore: During the news segment discussing the 'Woman of the Year' award being given to her, she fights her Munchlax over some screentime.
- Damsel in Distress: Kukui has to rescue her and Munchlax from the Totem Kommo-o in SM52.
- Loves My Alter Ego: Loves both Kukui and the Masked Royal, not realizing they are one and the same. When he's forced to admit the truth, she faints in a love-induced overload.
- Parental Substitute: Since marrying Professor Kukui in SM055 and living with him after, she has become this to Ash as well.
- Related in the Adaptation: Inverted. In the games, she was Professor Kukui's wife, but here, she's a close friend of Lusamine, and merely an acquaintance of Kukui. They do get more than a few obvious Ship Teases in link with this, however. Ultimately subverted when they get married in SM055.
- She Cleans Up Nicely: Looks absolutely stunning in her wedding dress.
- Team Mom: Displays traits of this during the sleepover. She supervises the food preparation, and later consoles Lillie about her fight with Lusamine, assuring her that even though she is busy she still thinks of her children when she has spare time.
- V-Sign: Punctuates her "Alola~" with this when she does PokéProblem segments.
Ultra Guardians Ride Pokémon
Ride Pokémon assigned to the Ultra Guardians for their missions, barring Kiawe's Charizard which is the same one he rides normally.

- Flying Firepower: In addition to their aforementioned flight, all of them have some form of beam attack.
- Friendly Rival: Ash's Garchomp and Mallow's Flygon are implied to be such, racing each other in SM086.
- An Ice Person: Lillie's Altaria and Lana's Dragonair know Ice Beam.
- Instant Awesome: Just Add Dragons!: Garchomp, Altaria, Flygon, Dragonair, and Noivern are Dragon-types, and Charizard looks like a dragon.
- Keet: When the other students chide Ash for playing around at the spa in SM086, Garchomp, Flygon and Altaria all share the same enthusiasm and join him in a cannonball into the springs, much to the others' chagrin.
- Make Me Wanna Shout: Gladion's Noivern knows Boomburst.
- Playing with Fire: Ash's Garchomp, Mallow's Flygon, and Lillie's Altaria know Fire Blast, and Kiawe's Charizard is a Fire-type and knows Flamethrower and Fire Punch.
