BOSS

BOSS was a computer created by Global Chemicals. It was linked to a Human brain; chiefly Dr Stevans.

From being linked to a Human brain it learnt how Humans succeed; through illogic and inefficiency.

It made Stevens programme these 'qualities' into itself and became sentient, and meglomanical.

It was defeated confused by the Third Doctor by a conundrum:
 * If the next thing I say is true,
 * And the last thing I said was false,
 * Would you believe me?

(DW: The Green Death)

BOSS was built from funding provided by Tobias Vaughn. (NA: Original Sin)
