|This article is about a/an rider machine in Kamen Rider Black.|
The Battle Hopper (バトルホッパー Batoru Hoppā?) is a living motorcycle used by Kamen Rider BLACK. It was created by Gorgom, made specifically for the upcoming Creation Kings Black Sun and Shadow Moon. The Battle Hopper has the ability to heal its own wounds if damaged, and can stand on its own if knocked over. His special move is the Dynamic Smash, a body slam attack that is executed at full speed. Before the finale, Battle Hopper is connected to the King Stones and was later controlled by Shadow Moon due to this connection and dies in the final episode, finally speaking to say how proud it was to fight with Black. Because of his strong connection to Kotaro's King Stone, he was resurrected as Acrobatter in response to the Sun King Stone's evolution.
Speed : 1000km/hour (621 mph)
The Acrobatter (アクロバッター Akurobattā?) is the revived version of the Battle Hopper. It is now capable of speaking coherent Japanese, and often has conversations with Kotaro. Whenever BLACK RX transforms into any of his two other forms, it does the same.
Acrobatter transforms into Roboizer (ロボイザー Roboizā?) when RX becomes Robo Rider. This form of Acrobatter has two blasters mounted at its rear.
Acrobatter transforms into Mach Jabber (マックジャバー Makku Jabā?) when RX becomes Bio Rider. .
