I have all of Lady Quark's appearances (mostly in LEGION) and the best character development was her 2nd appearance outside COIE (after DC comics presents 95 - or was it 94?) in Starman 8 (http://www.comics.org/details.lasso?id=45964), where she looks for a new king. She was replaced by a something in LEGION that 'killed' her. Bedard has expressed an interest in bringing her back in REBELS and Wildstar looks suspiciously like she could have once been Lady Quark - but I think he also said it was specifically not her.
