GOD / CALCULATING GOD / ENTITY

A species or entity which is believed to have triggered orchestrated sychrone mass extinctions  (440, 365, 225, 210 et 65 millions years ago) on several worlds in Earth's vicinity (at least Earth, Beta Hydri 3, Delta Pavonis 2 and possibly Groombridge 1618) and might be doing it on a even bigger, even galaxywide scale  to promote the evolution of sentient life.

This species/entity looks like a pitchblack sphere some 1.5billion kilometres wide. is known to be able to contain the showckwave of a Betelgeuse-sized star going supernova and to give to species that it deems mature enough the know-how to fuse genetic materials from several species to produces a new intelligence able to live in space and whose essence will possibly be able to survive the Big Crunch and create its own Universe.
