After 90 years of being in a jar his brain was put in a robotic body which was only supposed to use as a full power battery for the thing. But fate had other plans, he woke up full with the memory of his former self and was devastated because not only was everyone he cared about dead but he had no cause for living.

Your free to us him or Dr.Nullity as you please just explain where the character came from and if possible show me the finished or unfinished product. Since I'm a fan of continuity and like to see what becomes of this character!

Edit: Also note that when used my entire universe around this character crosses with yours.

Nice, reminds me a little of HERBIE from Fantastic Four or that little robot from the movie, "The Black Hole."
