Ni Tian Xie Shen (Against the Gods) (CN)

Against the Gods is a tale of revenge with a heavy dose of power leveling and face slapping. Red Rising is that and more, as both main characters rise of from the very bottom echelons of humanity in their quest to reach the top.

Overlord (JP)

Both feature protagonists who are not quite heroes. They are not the good guys but their stories are fascinating to follow. While Tenaka Khan is not a transmigrator like Ainz, his story is an evolution of his character as he ascends to rule.
