BOSS

BOSS was a computer created by Global Chemicals it was linking 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 Stevena 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)
