Blake is one of the characters of the day who appeared in Splitting Heirs! (episode 45). He is the younger brother of Heath. When they were young, Blake and Heath used to go on adventures, often getting themselves scratched up. They used to get along very well, and eventually both got an Espurr from their father. However, after their Espurr both evolved into Meowstic, they started to quarrel often. Wanting to prove himself to his brother and father, he left home to go on a journey. (Source: Bulbapedia)
