Larry is a serious, brooding man who works for Paldea's Pokémon League under Geeta, who assigned him the roles of both a Gym Leader and Elite Four member. He also works as a businessman on top of his Pokémon League duties. He is often unmotivated, and becomes unsettlingly still whenever he is lost in thought, much to the worry of people nearby.[1]
He uses Normal-type Pokémon at his Gym because he feels they reflect his ordinary image. In addition to the Gym Badge, Larry gives out TM025 (Facade) when defeated. During the Champion Assessment, he is the third Elite Four member to be faced and uses a team of Flying-type Pokémon per Geeta's request, much to his dismay.
Outside of his Pokémon League duties, he is known for his fixation with food, and regularly visits the Treasure Eatery of Medali, which also serves as the arena for his Gym battles.
Are you a regular here?: "Hm? Oh, yes, I suppose I do come here often."
Is that the secret dish?: "You must be a Gym Test challenger..."
"Well, what I’m having right now is something quite ordinary, but..."
"Here’s a tip for you. A nice squeeze of lemon gives any dish a refreshing kick."
Talking to him again
"Here’s a tip for you. A nice squeeze of lemon gives any dish a refreshing kick. Though...I daresay someone as young as you might not really appreciate that taste just yet."
"I think it’s time to show you that real life isn’t all just being true to yourself..."
Upon being defeated
"You certainly threw me for a loop."
After being defeated
"You’re rather strong, aren’t you? Enough to bring out my poker face, even."
"I lost, so that means I have to give you a badge, but..."
"That battle made me a bit hungry. Care to join me for a meal?"
"Having <number of Badges> Gym Badge/Badges in hand makes it easier to catch Pokémon of up to Lv. <level>. Oh, and they’ll actually listen to you, too..." (If the player has less than eight Badges)
"If you have 8 Gym Badges, you’ll be able to catch Pokémon of any level. They’ll never question who’s the boss, either." (If the player has eight Badges)
"The dishes here... They’ve all got flavor. Good flavor, I mean."
"This is for you. Though hopefully a child like you has no need to put on its namesake..."
"Oh, don’t worry about the bill. I do earn a salary, after all."
"Now, I’d better get back to work. If you’ll excuse me."
"It’s time for a meeting with the boss, but...seems I’ve got a visitor with no appointment instead..."
"This is absolutely something she’d do. No, no, I understand everything, I assure you..."
Either way:"Oh, of course, it’s no problem."
"La Primera IS my boss, so I have to do as she says...but now she’s ordering students around?"
"I see... So you’re helping the boss free up some time to enter a tournament at the academy?"
"Well, whatever floats your boat, I suppose. I’d never let myself get roped in like that..."
"... ... ...... ... ..."
"Well, let’s knock this task off our list, then. No use wasting time. Shall we?"
"The best thing to do with troublesome tasks is to just get them over with. Agreed?"
Yes"Let’s head to the Treasure Eatery, then."
No"I don’t have all day, you know."
Treasure Eatery
Before battle
"You already faced me during the Elite Test, so..."
"I doubt this will leave much of an impression on you. In any case, let’s get started, shall we?"
"I’ll be facing you in my role as a Gym Leader, so I’m going to use my regular team."
"They all belong to the Normal type. “Normal” as in plain...average...unremarkable...run-of-the-mill..."
"I’m pretty fond of them, you know? They suit me perfectly—I’m about as ordinary as you can get."
"People, Pokémon... There’s no need to overcomplicate things."
"Nowadays people only seem to want a shock factor. Something weird, something bizarre."
"At the end of the day, though, nothing beats the relief of coming home, even after a fun vacation."
"When all’s said and done, simplicity is strongest."
In battle
"The boss takes some getting used to, you know. You’ve got your work cut out for you…"
Before sending out final Pokémon
"You’re just plain strong, aren’t you? But I always output my best results when it’s crunch time."
Upon Terastallizing his Staraptor
"Time to show what we can really do. Same good work as always, please."
Upon using Staraptor's Facade
"I hope you find the power of this next move to be satisfactory."
Upon being defeated
"A third serving of defeat, huh…"
After being defeated
"You’re a bit too much for an average joe like me to handle..."
"But I think I understand now."
"Why I was told to use Flying-types when I battle as a member of the Elite Four, I mean."
"There’s scenery you’ll never even notice if you stick to flat, well-trodden paths."
"It’ll do me good to admire talent that soars as high as yours from time to time."
"Well, if the boss says I should do so, I’ll do so. She won’t catch me doing it for fun, though."
"In any case, I’ve been strictly told to cut down on my overtime hours, so...I’ll call it a day."
Trivia
Larry's Japanese Gym Leader title is 非凡サラリーマン.
As both a Gym Leader and an Elite Four member, Larry is the first character in the games to fill two different positions in the same Pokémon League simultaneously.
Larry's specialization in Flying types is hinted at by the cloud patterns on his tie and his ace Pokémon as a Gym Leader being part Flying-type.
Him specializing in both Normal and Flying types is likely a reference to how the Normal/Flying type combination is the most common type combination amongst dual-type Pokémon.
Larry is the only Paldean Gym Leader to:
Terastallize a Pokémon already of his type specialization.
