Howling:Who is the Hybrid?

So the Matrix has been having more and more projections focused on the Hybrid, right? That's why it's never been a big deal and we've never heard of it until now, even though the Doctor left Gallifrey because he was scared of his part in creating the Hybrid, apart from being bored or stealing the Hand of Omega. So the Hybrid could be the Doctor (possibly half-human, half-Time Lord), or the Doctor and Clara, or someone else. But if the Hybrid is a major threat, we've had a few of them.

Who else could be the Hybrid?


 * Donna Noble was part Time Lord/part human, and since that couldn't exist, her memories had to be erased.
 * If River Song was conceived in the time vortex, she was a human with Time Lord DNA.
 * The Timewyrm, a hybrid of Qataka and TARDIS components that threatened the multiverse.
 * As cool as it would be for the TV show to use a villain from the novels, she's already listed as a threat to Gallifrey, separate from the Hybrid.
 * Also, it could be said it was Qataka, the TARDIS, and a computer virus meant to kill her; so that would be three things, and a hy-brid is only two.
 * If Ashildr's theory about the Hybrid being two people (the Doctor and Clara) is true, maybe the Hybrid is actually her and Clara, traveling the universe in their own TARDIS while Clara's un-death threatens time and space.

Does anyone else have any theories? Steed ☎  02:40, February 27, 2016 (UTC)
