As much as I liked the retro Sentinel, I have so many misgivings about this one. Because let me guess: morphing and nanoprobes.
The Neverending Story (book, not movie) did that better as Ygramul the Many. As did almost every major sci-fi movie of the late '90s/early aughts. This makes me think of the Galactus cloud when it comes to missing the essence of a character (in this case, as Guillermo del Toro would say, "giant fooking robutt").
Also, is it me or does it look like Spawn without a cape?
Anyway, they're all revealed now. To see them side-by-side making a complete panorama, and even buy whichever ones you like best, well...Empire's got 'em.
