Frank

Frank is a horse, of Tenesse Walker race, who accompanies Arthur Morgan on his quest to find peace on both the Wild West and the civilized east. Though they have the same goals, Frank has no problems killing humans or animals as long as his friend doesn't have to get his hands dirty.

Not much is known of his origins, just that he lived in the Adler's ranch, where Sadie Adler lived with her husband. He has admitted to have a severe case of "cuniculiphobia", also known as fear of rabbits. Frank says this phobia was a way of balancing his powers, though he has not said anything about who or what gave him his powers and his irrational fear.
