Klara originally started off an underground pop singer with traits of cuteness and the virulence of poison. Despite her attempts at promoting herself, she only sold about eight copies of her debut album. After that she decided to try out being a Gym Leader as her new goal in order to boost her popularity. At some point, she obtained a GalarianSlowpoke. However, she gave up on that goal after two days of harsh training at the Poison-typeGym. She eventually learned about the Master Dojo thanks to a late-night TV show. After she saw how kind Mustard looked in the commercial, Klara decided to head to the Isle of Armor to train, believing she can become stronger without trying too hard. She quickly called the Dojo in order to apply.
She is first encountered by the player at Wedgehurst Station, obtaining the Armor Pass needed to visit the Isle of Armor. Before she can get on train, a Galarian Slowpoke appeared, blocking the way, requiring the player to catch it. After complimenting the player's capture of Galarian Slowpoke, she went on the train to the Isle of Armor. She eventually reached her location and became a student at the Master Dojo. However, she focused more on being doted on by others and barely worked on her training. This resulted in Klara becoming lazy due to lack of a rival and motivation.
The player meets Klara again once they arrive at the Isle of Armor. She challenges the player to a battle off the bat, assuming they are to be the Master Dojo's new student that she has been assigned to escort. After being defeated, she attempts to scare the player away from enrolling in the Dojo, and even lies to Honey about the student in question not wanting to show up, only for the player to eventually appear at the Dojo, much to Klara's shock. She threatens the player to not tell of what transpired. During Mustard's trials, her Dojo Uniform gets stolen by Mustard's three fast Slowpoke, which the player retrieves in short order. She battles the player over the next two trials, the former over a set of Max Mushrooms she claims discovered first, and the latter as part of a formal challenge. Klara cheats during the third trial by immediately summoning Toxic Spikes on the player's side of the field. She is eventually defeated, and feels guilty about playing dirty. Mustard asks Klara to look after the Dojo Pokémon afterwards.
In the post-game, after Mustard has been defeated in a final showdown, Klara can be rematched daily.
In the Galarian Star Tournament, Klara reveals that she has become a minor division Poison Gym Leader. After becoming a Gym Leader, Klara adds a GalarianSlowking to her team, having it replace her Drapion as the lead of her team.
"Klara was originally an underground pop singer. She promoted herself as a star that had both cuteness and the virulence of poison. She energetically held live concerts and other events, even selling some Klara-themed collectables that she made herself, but in spite of everything, she only managed to sell eight copies of her debut album "Krazy for Klara." She decided becoming a Gym Leader would help her gain more popularity and has been working towards that goal since. She chose the Poison type because it matched her image and there was less competition."
Rare League Card
"The training at the Poison-type Gym was a lot harsher than Klara was ready for, and she gave up after two days. It was during this time she saw an ad for the Master Dojo during a late-night TV show. The master seemed kind, and Klara thought it would help her become strong without having to try too hard, so she immediately called in to apply. Normally, Klara's sole focus is to be doted on by others, so she puts only the bare minimum into her training, but recently a new student at the dojo has caused a change of attitude. She now works secretly with her Slowbro to better herself."
Klara uses these three Pokémon as both a partner and potential opponent in the Galarian Star Tournament. She will Dynamax her Slowbro at the first opportunity if her partner has not Dynamaxed or Gigantamaxed themselves.
During the cutscene where the player receives Klara's rare League Card, she can be seen training with another GalarianSlowpoke. Its relationship to her final team is unknown.
If talked to prior to interacting with the Slowpoke
"Is this the first time you've seen a Galarian Slowpoke? The coloring of the top of its head is curry-like. Isn't it superduper cute?"
After catching the Slowpoke
"Wow! Amazing! The way you caught that Slowpoke was the absolute coolest."
"Okaaay."
"I'm heading to a place called the Isle of Armor. I'm gonna catch some rare Pokémon and do some training. Let's hang if we meet up again, 'K? Bye-bye, then! See ya!"
"Aha, there you are, right on time too! You're pretty punctual for a kid! Hmmm....Hey, have we met before or something? Oh, it doesn't really matter, I guess! I'm Klara! I've been at the dojo awhile, so they sent me to help out the newbie!"
What dojo?/I think you've got the wrong person... : "Oh, come on! I know you're the new student who's supposed to join the Master Dojo!"
"What's going on? Am I being mocked...by a kid?!."
"But I'm the colorful, caring, and charismatic Klara!"
"Well then... How about we have a quick battle? Just so, y'know, we can see who's better?"
"I'll be waiting outside, so come on out when you're ready!"
"Hee hee! I bet this is your first time on the Isle of Armor. I bet you can't wait to start exploring, but first things first! We need to make sure you're ready! Since I've already been at the Master Dojo for a little while now... I'll be the one testing you out! Go easy on me, Ok?"
In battle
"Remember, it's just a test--so take it easy! I'll be nice and gentle... as I knock you out flat!"
Upon landing a hit: "Look, the first damage you took on the Isle of Armor! Consider it a little gift from me!"
Before sending out final Pokémon: "How am I the one getting backed into a corner? This should NOT be a thing!"
Before using Acid: "Hah! That's right! Let my poison drive you Kla-razy!"
When defeated: "Oh, my next Pokémon's gonna make short work-- Huh? That was my last one?"
After battle
"Huh?! No no no! NO no no! Th-there must be some kind of mistake!"
"Not good... Not good at all, man... How'd this kid get so strong?!"
"If this kid joins the dojo, nobody's gonna pay attention to my strength... I could just tell him/her to buzz off... No, they asked me to bring in the new student!"
"Ahem! Hey, that wasn't bad! I mean, It's not like I was going all out--not at all--but still! Buutt...you see...our dojo is one that's got a long-standing reputation! Even the famous Champion Leon trained at our place!"
"No offense, but maybe, just maybe, you're not quiiite good enough to make it? Sooo... how about this? Why not enjoy the sights, but just stay away from the Master Dojo over there, 'K? Here, I'll even give you this! Y'know, as a souvenir!"
"Just show it when you visit a boutique or a hair salon, and they'll let you buy stuff that's not available to most people! Anyway... I guess that's that! See you never! Hee hee hee!"
Outside Master Dojo
"Seems that way, yep! I did my best to welcome him/her, but... he/she just suddenly left after our battle..."
"Huh? Agh!"
"Right, right, right, right! Exactly, ma'am! I swear! He/she must've changed his mind about joining the dojo! Oh, but here you are! I'm sooo happy you decided to come after all!"
"Aaaagh! Why?! How?! What does he think he/she's doing, just showing up like that?! This ain't good... Ms. Honey will know I lied!"
"Hee hee, I'm sure we'll be best friends!"
"Listen, you... If you dare tell Ms. Honey about what happened at the station... I'll melt you down to size! You understand?!"
"Aww! But, Masterrr! You haven't given me my uniform yet! Why does that kid get a uniform but not me?! It's not fair!"
"Hee hee! The squeaky wheel gets the grease!"
"Huh?! What was that?"
"Wha--?! It's gone! Where'd my Dojo Uniform go?"
"Huh?"
"Hey! Give it back! Give me my Dojo Uniform!"
"Hey! Get back here!"
After completing first trial
"You... Don't tell me you got my uniform back all on your own!"
Here you go!/You can have it back: "Oh... Well, uh, thanks."
"Uuugh..."
If talked to prior to starting the second trial
"Sorry, not sorry, but I haven't accepted you as the hotshot everyone else seems to think you are. You'd better think again if you think I'm gonna let you finish this trial before me, mate..."
"Master, Ms. Honey...please, can I ask for something, just this once?"
"I want you to use my Max Mushrooms in the Max Soup!"
"I really want to share my hard work with everybody here!"
"Ms. Honey..."
If talked to prior to talking to Mustard
"Hmmm? Did the master call for you, too?"
Upon speaking to Mustard
"Sooo...what's this all about, Master? What did you want to tell us?"
"The final...last...ultimate...third trial?!"
"Uh...so basically this is the last trial?"
"We're going to battle? That's the last trial?"
"This is it... Finally... But can I...?"
"I-I've gotta get going!"
"I need to go there right away to prepare my pure heart for this! I'm going on ahead, 'K? You can laze about like a Slowpoke and take as much time as you need!"
"When I beat you, I'll get the secret armor... and then I'll become a Poison-type Gym Leader! I've got to win, no matter what... I'm gonna go all out and totally beat you. You ready?"
In battle
"I'm not holding a single thing back anymore. Time to settle this--fair and square! Oh, and maybe watch your step... Looks like some Toxic Spikes somehow got on the Battle Court!"
When player lands a supereffective hit: "Sorry, my dear Pokémon! I should've given better directions. But hang in there! You've got this!"
Before sending out final Pokémon: "There's no way I'm losing! I ain't letting go till the bitter end!"
When DynamaxingSlowbro: "Watch out, audience! One dose of Klara poison and there's no turning back!"
When defeated: "But I didn't hold back! I gave it everything I've got..."
After battle
"Aw man... I totally lost..."
"Hah, well, this stinks. I do everything--even cheat a little--and still lose. I don't expect a young, talented kid like you to really get it, but... I... really was trying, you know? As hard as I could..."
"Maybe it's time for me to just give up on my dream of being a Gym Leader..."
"Once they find out what I did, I'll be expelled from the dojo anyway. <player>, you can tell the master that I cheated."
OK: "I'm sorry..."
I won't: "Huh? B-but why? It was supposed to be a fair battle, and I cheated just so I could win..."
"Um, <player>... I-I just...well...I guess I should congratulate you... But I won't! Why should I celebrate anything you do, huh?! Still, that cleared up a lot! You are strong enough to beat the master going all out! I never stood a chance! But the next time I face you... I'll take you on fair and square! And I won't lose... You'll see!"
I don't think I'll lose!/Are you sure?: "Agh! You're downright infuriating--you know that? Almost as bad as I am!"
"Ohhh, ex-CUSE me! Am I interrupting your private little chat?"
"That's exactly right! You sweet little thing! I'm so happy you remember me, Hoppy-kins!"
"I've been working real hard with my team since you beat us all into the dust before... And I did it! I really did! I finally became a Gym Leader!"
That's amazing!/Congratulations!: "Feel free to keep heaping on the praise and adoration! It really is a fantastic achievement! Even if our Gym is still in the minor division."
"H-Hoppy-kins..."
"Well, you can bet your bottom I'll be going all out in this event! Just you wait and see!"
"Hee hee! Don't worry--I'll knock you out nice and cold!"
On the field before the first round battle
"Seems like a great chance to show off just how toxic we can be!"
On the field before the second round battle
"Doesn't matter who we're up against! They'll all get a toxic dose of Klara and <player>!"
On the field before the final round battle
"Stand aside, <player>... I got this one!"
Winning the tournament
"Ahaha! You know, I really didn't like you at first, kid. But now that we've won this thing... I'm actually happy that I did it together with you!"
