The Decreator - Doom Patrol (2019)

Built by the pure faith of the Cult of the Unwritten Book, the Decreator was believed to be the shadow of the light of creation formed at the Big Bang. Others also mused that it was the umbra from God's light. Either way, it took the form of a giant eye that could cause organic and non-organic matter to cease existing in any realm. Their power was so absolute that it could even penetrate to other dimensions, including one inhabited by Mr Nobody and the captured Niles Caulder.

In 2019, after the Little Sisters of Our Lady Razer recovered and read the Unwritten Book, the Decreator was called into existence over the house of Niles Caulder and Cloverton, beginning the wipeout everything.

To counter this, the pair were forced to work together to create a new being entirely that would do the exact opposite, leading to the origin of the Recreator.  Both entities cancelled themselves out and disappeared.
