Brassius is one of the Gym Leaders of the Paldea region, and is also an artist known as the Verdant Virtuoso. He treats battles as an artform and tests the aesthetic sensibilities of those who challenge his Gym. His most remarkable artwork is called "Surrendering Sunflora", which is a statue installation spread around the town of Artazon depicting Sunflora with somber expressions. Art connoisseurs debate on what the Sunflora are surrendering to.[1]
In addition to the Gym Badge, Brassius gives out TM020 (Trailblaze) after defeating him.
"I am Brassius—an artist specializing in Grass-type Pokémon. I am also the Gym Leader here at the Artazon Gym."
"I was observing your Gym Test from atop the windmill, you know. The perception you displayed in finding Sunflora was truly... Oh, how shall I describe it?"
"Yes! It was truly avant-garde!"
"I only pray that you might demonstrate that eye for beauty in our battle as well."
"Enough talk! We must begin creating our collaborative work of art!"
"I trust that you are ready? It is time for our masterpiece to take shape!"
In battle
"Art is creation and destruction! Struggle, else your defeat will nourish my Pokémon!"
Before sending out final Pokémon
"This has promise! Yes! Let us lead this artistic endeavor to its conclusion at once!"
"Allow me to touch this work up slightly! I will call it... “Truleewoodo”!"
Upon using Terastal move
"At times, art becomes a race against the clock! Let us increase the pace!"
Upon being defeated
"Avant-garde!"
After being defeated
"Oh! What artistic tactics you employ!"
"The patterns of your moves! The minute details of your Pokémon’s performance! Everything you did was honed to perfection!"
"Our battle was, in a word, art! Indeed, if we could not call that a work of artistry, then nothing else in this world could be labeled as such!"
"If I were to judge your work, I would say it passes my inspection. Yes—a pass without exception!"
"As proof of your artistic prowess, you may have my Gym Badge! Shall we take a photo as well?"
"If you possess <number of Badges> Gym Badge/Badges, it will be easier to catch Pokémon of up to Lv. <level>, and those Pokémon should follow your commands as well!" (If the player has less than eight Badges)
"If you possess 8 Gym Badges, you will be able to catch Pokémon of any level. And they will most certainly obey your every command as well!" (If the player has eight Badges)
"To a fantastic Trainer such as yourself, I would also like to offer this—a favorite of mine!"
"Ah! My inspiration is overflowing, as if drawn from a bottomless well!"
"I will begin on a new piece at once! You must excuse me. Farewell!"
