Lobot was actually named in ESB. Every time two Bespin residents are onscreen, if you turn it way up, you can hear one ask the other, "Dude, where is that pimp, Lobot?"
If TRU with its carpy selection and high prices are keeping toys alive, then they've actually been dead for years. I wouldn't mind paying $1 more, if I actually knew I could get stuff there. I just happened to see Galvatron and Acid Storm while with my parents, looking for baby gifts, and figured they'd be at Target later (and cheaper), since none of these TF Universe Deluxe figures have been hard to find (though I hear some say Grimlock was, I never saw that).
