In season 1 of Zorro (1957), Zorro's horse, Tornado was black, but in the first half of season 2 it was white, and the second half the season it was black. Was this oversight, or two different horses? Maybe I just wasn't paying enough attention to plot details. If it was two different horses what was the name of the second horse and what happened to Tornado?
When Diego is in Los Angeles, he rides Tornado (the black horse) when he becomes Zorro. When Diego traveled to Monterey, he did not take Tornado with him, and a new horse named Phantom (the white horse) was introduced. Phantom was given to Zorro by a dying soldier and it is not revealed in the series where Phantom hides out while Diego is in Monterey — or what happened to him after Diego returned to Los Angeles.
