American comic book Devil, starting with the creation of Spider-Gwen

Rilin travels through the Marvel world, is born with mastery of the life dimension, and becomes a unique life dimension demon!

Apocalypse, the ancestor of mutants: A mere mortal ant, I am the immortal king of mutants!

Lilin: You are life, so deprivation of life (Apocalypse burps), I am the source of vitality, immortality is nothing

Cybertronian Unicron: I am the master of machines. Machines will eventually destroy all life, and the God of Life is no exception!

Rilin: Silicon-based life is also life, so life is deprived (Unicron turned into scrap metal). Who says the life demon cannot kill mechanical creations?

Purple Potato Demon Thanos: The world needs balance, I will kill you to rebalance the resource distribution of the universe (six infinity stones, snap your fingers)

Rilin: It’s still deprivation of life (infinity stones turn into powder), existence is life, it’s not you who have the final say about what life is, but I have the final say!

What is the Life Dimension Demon?

Do you think it's a dimension lord like Dormammu? Wrong, it’s a conceptual god like the River God.
