As I mentioned before, Alto pilots the VF-25 Messiah, one of the S.M.S's latest variable fighters. These units are able to transform in two or more modes, these usually being: the ~normal~ plane type, the humanoid one called Battroid and an in-between mode called GERWALK. One interesting fact is that they're commonly known as "valkyries", since they were mass-produced using the VF-1 Valkyrie as reference.

Developed for the New U.N. Forces, this model wasn't distributed, but instead was delivered to the S.M.S in order to test it in many aspects, like real fights.

According to an article in the June 2008 issue of Kadokawa Shoten's Newtype magazine called "The Official Art of Macross Frontier", the name "Messiah" (メサイア) invokes the image of Alto's white model and the lyrics of the song "Shao Pai Long" ("Little White Dragon") from The Super Dimension Fortress Macross. ¹
