I reviewed Darkstars, I called it a "forgotten" comic book. Well, I didn't know how good I had it then. I would never have known Bob the Galactic Bum even existed if an ad for it in an issue of R.E.B.E.L.S. hadn't caught my eye. It had Lobo in it, but as in the 1990s, every DC Comics house ad has Lobo in it, my eye would have glazed right over it if the ad hadn't also highlighted the presence of Stealth (one of the main characters of L.E.G.I.O.N. and R.E.B.E.L.S.) and the Khunds (recurring DC outer space bad guys). So I googled, and discovered the existence of this four-issue miniseries from 1995.
Frankly, it's weird that the only place this is mentioned in R.E.B.E.L.S. is one ad, as it feature three characters from the series (in addition to Stealth and Lobo, R.E.B.E.L.S. leader Vril Dox turns up) and it takes place between its issues. Plus, one of its co-writers, Alan Grant, wrote or co-wrote the first 39 issues of L.E.G.I.O.N. Surely DC would have wanted to make sure fans of the one found the other, but there wasn't even a mention in the lettercol.
This story is no Judge Dredd adventure, however. It's a light comedy about a "galactic bum" named Bob, who seems to be a stereotypical British bum, complete with ratty top hat. Bob travels the universe with his companion Buck Fifty, who can only say "What?" and the story opens with him being picked up by an interstellar cruise liner carrying a prince. Bob is offended by the prince, who he calls a "piker" (i.e., a tightwad), but when Khunds attack the cruise liner, Bob, Buck, and the piker are the only ones left alive. Bob sees the opportunity to finally make his fortune, but that means getting Prince Gazza of Chazza back to his homeworld in time for the coronation while avoiding Khunds and Lobo.
Lobo apparently became a woman named Asbo!)
