A new commission, hot off the press. The four leading ladies of the Tenth Doctor's era, plus a variety of 'bots and beasties.

My introduction to Doctor Who was when I was about eight or nine, watching "The Brain of Morbius" on our local PBS channel. It was a perfect "first taste" for my unindoctrinated child mind- gothic horror with a sci-fi twist, some scary witches, a brilliant but mad scientist in a secluded castle, an alien twist on Frankenstein, mysterious talk of something called "the Time Lords", and of course a strange madman in a box and his plucky companion. That companion was Sarah Jane Smith, and Lis Sladen's performance made a crazy story that could have been laughable seem real and dangerous (just look at the scenes where she's been temporarily blinded if ya don't believe me). To me, she'll always be the original "Doctor Who girl".
Sarah Jane fans may also want to check out our new webcomic, "Sarah Jane Smith: Final Report"...

Judoon and Slitheen- many appearances in Doctor Who.
The Trickster tried to kill the Doctor (by proxy) in TURN LEFT, and had expressed his desire to destroy him as early as his first SJA appearance. They finally meet face-to-face in THE WEDDING OF SARAH JANE SMITH.
A member of General Kudlak's race (the Uvodni, if I remember the name right) appeared as part of the Pandorica Alliance in THE PANDORICA OPENS. For all we know it IS Kudlak (they have the same coat)!.
And Sontaran Commander Kaagh (sp?) was part of General Staal's invasion force in THE SONTARAN STRATEGY/ THE POISON SKY. We see his pod (and him in it) very distantly- a shot that appears again in SJA where we see how he crashed down on Earth when Staal's ship exploded. He blames the Doctor for his scars and makes it clear he wants revenge on him eventually.
So technically they're all enemies of the Doctor.
I haven't watched Turn Left in a looooong time (Heck, probably only once), so I probably didn't make the connection between the trickster and the Beetle
