Lady Quark is a fictional character, a superhero in the DC Universe. In the DC Comics 12-issue limited series Crisis on Infinite Earths (1985-1986), the character was one of the rulers of Earth-Six, which was ruled by royalty. In 2011 introduction of The New 52 DC Multiverse, she and her husband Lord Volt are now the monarchs of Earth 48, which appears to be a modern analogue of Earth-Six in the original DC multiverse.

Lady Quark comes from Earth-Six, where the American Revolutionary War was not won by the Thirteen Colonies and where technology has become more advanced than Earth-One. Lady Quark, her husband Karak ("Lord Volt"), and daughter Liana ("Princess Fern") make up the royal family that rules Earth-6. While Lord Volt and Princess Fern are both killed when Earth-Six is destroyed during the Crisis, Lady Quark is saved at the last minute by Pariah, a dimensional traveler. Lady Quark helps most of the multiverse's surviving heroes and they journey to the Dawn of Time to battle the Anti-Monitor. After the Crisis is over, Lady Quark resettles on Earth with Pariah and the Harbinger.

Missing her husband, Lady Quark approaches Will Payton with the idea of having him become her consort in Starman #8 (March 1989), but Payton rejects her advances.

Lady Quark is eventually recruited by Vril Dox to become a member of the peace-keeping force L.E.G.I.O.N. in L.E.G.I.O.N. '90 #18. Lady Quark is apparently killed in L.E.G.I.O.N. '94 #62 after a parasitic shapeshifter absorbs her memories and powers. The shapeshifter replaces her in L.E.G.I.O.N., but later dies in L.E.G.I.O.N. '94 #70. Lady Quark's corpse is later seen floating in space, heavily maimed.

Lady Quark has not been a contender in any CBUB matches.
