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."
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.
