BOSS

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

Biography
From being linked to a human brain BOSS 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 (specifically 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?

The BOSS was enraged at its inability to solve this paradox and even tried to talk its way out of needing to solve it by saying the question was not relevant. The Doctor was quite satisfied with himself at the BOSS' inability to answer, though the BOSS decided to throw the question out the window and simply summon security (showing another mental advantage it had over its fellow god-complex ridden computers).

The BOSS saw what was good for Global Chemicals was good for the world. It had a less serious side, unlike most early AIs. It was disappointed that its human partner in crime was agitated at the idea of singing at the triumphal moment of linking humans minds together into the BOSS, so it sang a slightly off key but well humored verse itself.

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