Crisis Protocol Mister Sinister Expansion

Once, Nathaniel Essex was a biologist in Victorian London.
Realizing that an increasing number of human mutations signaled
the beginning of a new evolution, Essex put aside morality in his
pursuit of perfecting the human race. A long road of unethical
experiments on unwilling subjects eventually led to him to
incredible discoveries and even greater personal power.
Becoming something far more than human, Nathaniel
transformed himself into the nearly-immortal being known as
Mister Sinister. Mister Sinister views the mutant race’s eventual
dominance over the world as a foregone conclusion, and that
now we must look beyond the next step. Believing that certain
genetic bloodlines possess greater mutant power than others,
Mister Sinister has targeted members of the X-Men as potential
experimental subjects. Regardless of the opposition, Mister
Sinister will allow nothing to impede his quest for evolutionary
perfection.
