The original post for Lazarus

Lazarus's updated design!

Instead of this being simply a redesign of my character, there's actually a canon explanation for his change in look, even if he is made out of ferrofluid.

Lazarus, for many, many years since leaving his homeworld of Earth, has had a habit of building life-like android AI bodies for him to embody, and live entire lives through. He'll design a character, possess it with his machine controlling abilities, and become a part of some random world and society, living full 50-100+ year lives as these characters, until he plots out the character's death and moves onto his next life to play through. It's something of a hobby of his.

Each time he leaves a body after being in it for so long, his "default" form changes slightly. The original design as seen in the link above, is how his default form originally looked when he was first created thousands of years ago, and this art piece is him in modern times.

Mind you, thousands of years ago doesn't mean ancient history to Earth. At the time Lazarus was created, Earth was already well into space colonization in the year 30XX.

Personality-wise, Lazarus himself is still seemingly simpleminded and laid back, even if he is genius enough to casually design life-like android bodies.
