Maximus is a large white horse with a blonde mane and tail. He wears a distinct saddle with the sun symbol of the Kingdom. Maximus is described as a dedicated character who will stop at nothing to take down the criminal he is after. Maximus is brave, daring, bold and not at all cowardly even being more feared than his captain. Maximus is a horse but has a personality more similar to a dog. He is very intelligent, and can apparently understand human speech, as his facial expressions so obviously confirm. Although Maximus can be extremely tough, he has a large heart, can't say no to a young girl like Rapunzel who calls him a big sweetheart, and even becomes best friends with his former arch enemy Flynn Rider as they join together to reunite Rapunzel with her family.

Horace Horsecollar is a funny animal cartoon character created by Ub Iwerks and Walt Disney. He is an anthropomorphic horse, one of Mickey Mouse's best friends. Characterized as a cheerful know-it-all, Horace helped Mickey on his sleuthing expeditions in the comics before Goofy assumed that role. Horace has never really been more than a supporting character, though he has starred in numerous European comic book stories of his own. In these, he plays a much bigger role than elsewhere, accompanying Mickey on his adventures or acting as Clarabelle Cow's paramour and fiance. Clarabelle and Horace were engaged in the comics according to some 1931 and 1932 continuities, but neither ever followed through.
