Just when you think Superman can’t get any more evil, the unhinged hero uses his heat vision to kill Black Canary in Injustice: Gods Among Us: Year Two #22. Canary and Harley Quinn swore vengeance against Superman after he killed both of their baby daddies: Green Arrow & Joker.
Harley helps take down Superman’s allies including the Flash. The former Arkham psychiatrist tells the misguided hero that she has been tasked with reprogramming him. She uses electro-shock therapy with a Superman doll to create an aversion to his super friend.
Canary enrages Superman by telling him she’s glad Lois died before seeing the “evil, murdering dictator” that he’s become. It lures him close so she can shoot a Kryptonite bullet, though she intentionally avoids vital organs. The bereaved widow tells him she’s sparing him at the request of Batman, who is still recovering from a broken break courtesy of Supes.
Victory seems assured when the Green Lanterns defeat the Sinestro Corps but one of the yellow ring from a felled enemy finds its ways to Superman. “You have the ability to instill great fear,” the ring tells Superman as if to confirm his fall from grace. He uses the ring to make a yellow construct and remove the bullet. The ring only fuels his rage. Superman fires his heat vision at Dinah, who looks down in horror at the holes in her stomach.
Yellow Lantern Superman stands over the lifeless heroine but we don’t know if she’s really dead. No vital organs were hit and the heat vision may have cauterized the wound. In fact, we see no blood. If she did survive, expect her to go back on her promise to Batman.
Perhaps Harley will have the last laugh and be the one to kill Superman. It would bring the series full circle by having her avenge the death of the Joker. The summary execution of the villain for killing Lois Lane was the first of many lines crossed by the champion of truth, justice and the American way.
