Halo's IRL dad is Dancing Brave, in Uma the horse Rigantona (the hot brown one in that image) is based on Dancing Brave but like the Cinderella Gray horses has a different name because they're not officially partnered/licensed, like Obey Your Master in CinGray being the IRL horse Pay the Butler who won the Japan Cup (spoilers for cingray I guess)

King Halo's mother isn't explicitly said to be Rigantona in-game and the one on the phone is probably Dancing Halo since she's the actual mother of King Halo and where she gets her namesake
