Prior to the 50th anniversary, it was believed that at some point between the 1996 movie and the 2005 series restart, the Eighth Doctor regenrated into the Ninth Doctor during the Time War.  However, in the minisode prequel ''The Night of the Doctor,'' it is revealed that the Eighth Doctor regenerated into another incarnation called the War Doctor.  In ''The Day of the Doctor,'' which is the 50th anniversary special, the War Doctor is shown to be someone who has seen much, as this incarnation fought in the Time War.
