Imagine if you will, a future where the fanastic four eventually perished, save for reed richards, whose disembodied brain lives on in a secret lab beneath new york, alone and forgotten. that is, until a young mutant stumbles upon this lab, and tells the brain of the world above, a world in need of heros. moved by the lad's words, Richards installs himself in a robotic duplicate of the Thing, and joins Mutant 2099 in protecting the streets of new york for human and mutant alike.

as you can see, Big Brain draws from several archetypes, and was indeed a royal pain to build.
