Successfully gathered all the Acadian gym badges a couple years ago, but wasn't interested in challenging the Regional Elite. Competing on the Acadian Pokémon Glamour League (APGL) now, usually with Camellia and Lily.
Isaiah Daniau is his boyfriend and a rival in the league competitions, though sometimes they also ride together. Dino thinks he's gay, or at least thinks women are too intimidating to try dating, this opinion not helped by the kinds of women he spends most of his time around.

Pokemon:
Lily, Vulpix (met and allowed him to catch her on the road; is a Clary, of the particularly vain kind)
Rook, Rookidee (raised from egg; is a Jalex - smol, but full of evil)
Enzo, Torterra (given to him by his mentor before his journey; very protective of Dino and his team, not the smartest)
Camellia, Rapidash (raised from egg, vain as all get-out, thinks Lily is her baby)
Erika, Zebstrika (going away present from his uncle; dumb as a post, but very enthusiastic)
Clyde, Mudsdale (essentially became his while working on his uncle's ranch; gentle giant, sweet, placid, busy with mudsdale things and has no time for human intelligence tests)
