Explanatory spoiler for those who don't want to read Worm, a million words of deconstruction/reconstruction of superhero comics:

The source of superpowers is a pair of gigantic multidimensional alien creatures. Their eternal mission involves finding a planet with intelligent life, infesting them with powers via brain tumor neural links, and encouraging them to fight so as to generate new ideas -- the aliens are profoundly uncreative, even stupid by human standards, but immensely powerful -- and when the planet is no longer producing, they reincorporate all the changed and combined powers, then eat the local sun to power their next FTL hop.
When their experimental subjects aren't moving fast enough, they open up their archive and resurrect the Endbringers -- superpowered kaiju which provide a stimulus for cooperation by destroying cities on a schedule. Each Endbringer is unique. The Simurgh, or Ziz, takes the form of a giant statue of a woman covered in angel wings, and wings-on-wings, and so forth. Ziz has primarily psychic powers: telekinesis; a 'scream' or 'song' that drives people to violent insanity over the course of an hour or so; and mind-control that seems limited to slowly changing supers into creative serial killers and mad scientists and so forth. Ziz floats in orbit, preventing space travel, and periodically descends to the surface to terrorize a city.
Everything escalates. Every trope is explained.
Boo. Hiss.
