[@Tearstone] Umbraxis is a world eater, it can consume entire planets.  However, the avatar at the moment is only a fraction of the full creature's power.  Right now it is simply feeling the world out, entertaining itself by slaughtering countess people.  Police Chief Jessica Valdez called it out and claimed they could beat it, and now it is simply responding to the challenge out of curiosity, killing cops in the Station along the way.  If your father is there, he is in danger of running into a Cosmic-Level villain, if not, nothing to worry about.
