Valkyrie (ヴァルキリー, Varukirī) is a 4-year-old stock horse with Australian roots and the horse that Gyro Zeppeli rides in the Steel Ball Run race. Gyro specifically chose the horse for its stamina and durability. As noted by Diego Brando, Valkyrie has a quirk where it sways suddenly to its left for every eight breaths it takes.[1]
After the race is over, Johnny brings the horse back to Naples.
Valkyrie makes an appearance in All Star Battle (PS3) as a technical playable character through Gyro.
The Mini Horses (手のり馬, Te Nori-ba, lit. Hand Horse) are extremely small horses who are the mascots of the Steel Ball Run race. They march around Steven Steel's feet in the opening ceremony of the race before Steven gives his speech.
Slow Dancer (スロー・ダンサー, Surō Dansā) is an 11-year-old appaloosa and the horse that Johnny Joestar rides. Initially, it proves difficult to tame, but by the start of the race, it manages to warm up to Johnny and hoists Johnny onto the saddle by hoisting him and causing him to roll along its neck. Though Slow Dancer is old, it does not lack in stamina, and Gyro states that choosing the old horse is better due to the horse's experience, as opposed to the younger horses that hold much power but charge into danger without an afterthought.[2]
During a flashback in JoJolion, Johnny and Rina Higashikata can be seen riding a horse that appears to be Slow Dancer, although it isn't explicitly stated.[3]
Silver Bullet (シルバーバレット, Shirubā Baretto) is a 4-year-old Arab thoroughbred and the horse that Diego Brando rides.[4] It has a pale star-shaped mark on its forehead.
Silver Bullet makes an appearance in Eyes of Heaven (PS3/PS4) as a technical playable character through Diego.
Hey! Ya! (ヘイ！ヤア！, Hei! Yaa!) is a 4-year-old quarter horse that Pocoloco rides.[4] Despite the lack of skill demonstrated by both the rider and the horse, Hey! Ya! manages to survive and propel Pocoloco to second place in the finish line after Diego Brando (this changes to first after Diego's "disappearance").
Roxanne (ロクサーヌ, Rokusānu) is 5-year-old Arab ridden by Indian racer Zenyatta Mondatta. His rider is also named after an album by Police. Zenyatta and Mondatta were Oingo and Boingo's names in Viz's American translation.[4]
Nut Rocker (ナットロッカー, Natto Rokkā) is a 5-year-old Arab ridden by Russian Racer Baba Yaga (also a Mussorgsky song covered by Emerson, Lake & Palmer).[4]
Black Rose (ブラックローズ, Burakku Rōzu) is a big black horse that is a bit sensitive. Diego Brando was leading the horse while Nicholas Joestar got on top of it. Nicholas intended to ride the horse in his next tournament.
Nicholas was capable of controlling the horse perfectly despite its size. However, he falls off the horse after some time and ends up dying. Diego says that he saw a white mouse scuttling near Black Rose's legs, which startled it and caused Nicholas to fall.
This Silver Bullet is an alternative version of Silver Bullet, ridden by Alternate Diego Brando. It is likely a 4-year-old Arab thoroughbred just like its original counterpart, and its features are similar to its original counterpart.
It is unknown what happened to the horse after Alternate Diego's death.
