Tear Jerker / Dial H for Hero

• At the end of "Who's Pulling the Strings?" from Adventure Comics issue 489, after defeating the villain the Marionette, the heroes realize he's dying and offer to take him to a hospital.
  Marionette: No. The exertion, and Earth's alien environment, have finished me. But at least I am free of the Controller.
  Chris: Then it was the real villain! You were innocent!
  Marionette: Not really... you see, I created it. I intended it to be the perfect artificial brain, with all the potential of a human brain, but able to use it as no human could, at least not on any planet known to me. And you have seen its power.
  Chris: But why use that power for senseless destruction? And why here?
  Marionette: That was my great error. I made it too human. My artificial brain was... insane...
• The ultimate fate of the person who transformed into Shocking Suzie in H-E-R-O. The Dial was lost, and he was unable to transform back into his male form. Not only that, but he lost his job as a construction worker because they "didn't want a girl on the team," and his girlfriend left him because it was too awkward for her. In the end, she ended up working at a strip club under her heroic alias, and after a time, her powers even disappeared because of her depressed mental state. And by the end of that series, the reader finds out she was murdered by someone hunting down dial-users to try and obtain the Dial and its power for themselves.
