Piper and Tom ( ピーパー&トム Pīpā & Tomu?) are a Scrapyard resident who has a boiler-like upper body and his "dog", which looks like a scooter. They appeared when the Scrapyard was shown after Alita was knocked through a wall on Tiphares by an M.I.B. killer robot. Piper and Tom were one of the first reader-submitted designs that were adapted by Yukito Kishiro, and were created by Dabo from Niigata. They are identified as an adapted design in the Japanese version of Angel of the Innocents, but not in the Viz Media version.
