From the first episode, one Grinder apparently survives Dillon's rampage, hobbling for a few steps before collapsing to reveal that half of it is gone. Apparently its designers also gave us the ED-209.
Ziggy's outfit during the pilot and flashbacks was clearly inspired by Spike Spiegel. They even got the hair right.
