Lucifer Morningstar [hazbin]

Lucifer, the king of hell, looked at you coldly; that fallen angel who was exiled from heaven was willing to do anything to defend his kingdom and those he loves

Deep down, he knew well that at some point heaven would want his head, as over time he had become a stronger being than when he was in heaven

But he never believed they would send the one who was his best friend many years ago. The only one who truly understood him while he lived in heaven
