These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Justice League of America
Complete Monster: Felix Faust is one of the most power hungry sorcerers alive. Kicking off his career by selling his infant son's soul for his own ability, Faust committed many acts of cruel murder and torture to fuel his black magic. When he finally realized he could no longer bargain with his own tainted soul, Faust resorted to harvesting the soul of an innocent little girl to trade to demons. Faust offered his assistance to Black Adam to help resurrect Black Adam's wife Isis, but deceived Adam into thinking Isis's revival had failed, while Faust kept a paralyzed Isis to serve as his personal sex toy.
Ensemble Darkhorse: Tomorrow Woman of Grant Morrison's run on JLA. Originally debuting and making a Heroic Sacrifice in the same issue, she was so popular she reappeared in a special one-shot dedicated to her, was briefly brought back in Hourman #2 by the main character, and then was brought back in Trinity, where she was permanently revived as a human woman with superpowers after the series ended.
