ROM: Spaceknight is unquestionably one of my all-time favorite comics. Part of that is just because of how weird it is -- a licensed toy tie-in launched before G.I. Joe and Transformers for a line of action figures that only included exactly one toy that fleshed things out by dropping him straight into the Marvel Universe and ended up running for 75 issues, plus annuals -- but really, it's more because it was really good. Writer Bill Mantlo managed to take the bare minimum of source material and build something that was operatic and compelling, on par with anything else of the era.
Tragically, Mantlo -- also the co-creator of Rocket Raccoon -- was struck by a hit-and-run driver in 1992 and suffered a traumatic brain injury, bringing his comics writing career to a close and leaving him in need of constant care. There's been a surge of awareness about him lately, and the the latest is coming from Rob Harrington, whose ROM Remix Project has seen 20 artists re-creating the entirety of ROM #1 in an effort to lead more people to Mantlo and raise money for his ongoing care.
