An alien super computer that you won't find in your local store.
Mr Smith is a super
computer with a difference. He is a Xylok crystal life form from outer space
that can connect with computer circuitry.
He assists Sarah Jane housed
in the attic of 13 Bannerman Road disguised as a chimney, helping with
everything from identifying strange and extra terrestrial life, scanning the
universe for star ships and planets, diagnostics of alien technology and the having
the occasional argument with K-9.
He remains a loyal and
trustworthy friend and ally after a slight reprogramming from Alan and
continues to assist Sarah Jane in her investigations.
