Lord Eclipse is still similar to how he was before resetting the world, though there is slight differences. For example, he's more bored since he got rid of anyone that caused any amusement to him, despite keeping Sun around. He's still egotistical, thinking that what he's doing is correct. He's also cruel and a malevolent ruler, coming up with extreme punishments or just straight up murdering people, although he said he was getting rid of all that.
