Rex is the loyal companion of the BB Bandits. Being a dog, he obviously doesn't talk much, yet his thoughts are usually translated in parentheses. Although he talks in barks and growls, he is very loyal and well spoken in his speech. Later on, he gets a dog translator that actually helps Rex express his own thoughts rather than having someone translate them for him

Would like a very gravely, mid to mid-low voice, being able to hit various growls and barks when needed
