AKA
From Tardis Wiki, the free Doctor Who reference
AKA, also known as the Metamorph, was the tweflth incarnation of a Gallifreyan.
He was a representation of all the DNA that the Gallifreyan had absorbed over the course of their lives, constantly shifting forms from one moment to the next, resulting in AKA representing a blur more than a single lifeform. (PROSE: Interference - Book Two)
