DC Universe-What's a Suneater?

so...does anyone have an answer? just some basic info

It's a force in the cosmic nature of space. It feels hungers and consumes energy from different suns. Kinda like Galactus but suns instead of planets.

They were artificially created by the Controllers. They look like giant clouds of gas or nebulae, they can eat suns and planets and fire beams of stellar energy.
