This is Zhao Yun Gundam's beloved horse. It is a famous steed said to be able to run a thousand li during the day and five hundred li at night. The Hiei Sen that came with the BB Senshi version of Zhao Yun Gundam had the same design as the Silver Meteor Horse, but for the anime adaptation, it was equipped with armor such as a face shield. This is an homage to the version that appeared in the manga with an altered design. It also incorporates a gimmick that allows Zhao Yun's weapons to be attached to various parts.
