BOSS

BOSS was a computer created by Global Chemicals. It was linked to a Human brain; chiefly Stevens, the director of Global Chemicals.

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

It made Stevens program these 'qualities' into itself and became sentient, and megalomaniacal.

It was confused by the Third Doctor with a logical paradox (spefically the Liar's Paradox):
 * If I were to tell you that the next thing I say will be true,
 * But that the last thing I said was a lie,
 * Would you believe me?

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