Devlin is the 2nd pokemon to enter Minagi's party. He was given to her by a friend as an egg, and due to her close friendship with his father, Minagi ended up spoiling the crap out of him. He's very careful, and has slight OCD, and is very alert to sounds. Despite those traits, he retains a very "cool" image.
As with all teens, he's very standoffish, and hates being bugged by children. He hates being clung to by Aine, and threatens to beat Loki's ass.
Being the grass type landed him in charge of the berry section. He tends to eat the berries, forcing customers to place orders rather than buying what's in stock
