Jet Enduro is one of the four main playable characters in Wild Arms 3. Jet is a loner and drifter, seemingly cold and unemotional. In many ways, he's the 'silent protagonist' of the story, focusing most on the needs of the day. He's practical, to a fault, and seems almost mercenarial in his behavior. His coldness is due to his lack of attachments to others, and lack of memories about his own past.
The only thing he does know is that he was taken care of by Werner Maxwell, Virginia's father, and he's the one who teaches Jet to survive in the wasteland. This relationship somewhat complicates developing feelings between the two, though Jet finds her annoying throughout most the story. Jet's portion of the story is to learn about his past, and what exactly his connection to Filgaia's state of decay really is.
It is revealed to the party in Chapter 3 by Leehalt Alcaste that Jet is actually an android named Adam Kadmon created by a member of the Council of Seven named Elliot Enduro. The party discovers this at the dungeon Deus Ex Machina, just prior to doing battle with Leehalt.
He's referred as "Boy Who Broke In" in the character selection (prologue).

Nothing pleases Jet more than priceless treasures (and peaches). He is a lone wolf drifter not used to accepting help or the company of others. He is cold-blooded and has the potential to do anything to get his way.
