Emils

Emils (エミルス) was a character appearing in the mobile game, That Time I Got Reincarnated as a Slime: Isekai Memories. Izis created him as part of the Mad City, a mirror version of Rimuru City, with Emils himself being based on Rimuru Tempest through the dreams and desires of Shinsha. When the Mad City dissipated, so did Emils.

Appearance
Emils looked nearly identical to Rimuru Tempest, with the exception of his light pink hair, red eyes and a crown on his head.

Personality
He has a cold and evil personality. Though he sees everyone in Mad City as his "Family" and values them as such as he gets enranged whenever one of them is harmed or killed, due that part of his personality being influenced by Shinsha’s desires to be family together with Rimuru which she was dreaming about when Emils was created. He hates being called a copy, knock off, rip-off or any kind of mention of being a copy of someone.

He eventually changed a bit in his final moments as Mad City disappeared as he told Rimuru to promise him to watch over his loved ones before fading away.
