Species: Dog

Breed: Bulldog

What he lacks in brains, he makes up for in his uncanny ability to taste minute differences in coffee blends. Oh, and he’s strong too, but that’s genetic. Rex also has a secret passion for cooking and is especially fond of baking cookies. Rex, along with Fox, is a member of Bino's posse, and can usually be seen around him. He usually tends to go along with whatever Bino's up to, and shares his cat-lover bias, though there are special occasions when he doesn't always agree with him. Rex serves as one of Bino's tough guy lieutenants and an intimidating, somewhat slow-witted figure of menace. However, time goes on, Rex emerges as not just the generic tough bully, but rather a gentle giant in the wrong crowd, engaging in hobbies such as baking cookies.
