Digimon Tamers
In "Digimon Tamers", Grani was the name of the refitted 'Ark', which was used as a steed by Gallantmon late in the series. It was directly stated in episode 47 that it was named by its creators after Siegfried's horse, Grani. Grani would later be used to upgrade Gallantmon into his Crimson Mode during the finale of the series and in one of the theatrical movies.
