Hybrid

A hybrid is a lifeform produced from either the mating of parents of two different species or a mixture of DNA from two different species.

List of Hybrids

 * In New York 1930 the Cult of Skaro created two forms of Dalek-Human hybrids. Dalek Sec became a Human-Dalek after merging with Mr. Diagoras, and Dalek-Humans were created by Dalek DNA implanted into dead human corpses; these were also given Time Lord DNA after an attempt by the Doctor to destroy the transmitter on the top of the Empire State Building resulted in him being struck by lightning, fusing his DNA into their genetic code and causing them to question the Daleks' orders. (DW: Daleks in Manhattan/Evolution of the Daleks)
 * By implanting the Human Factor into Alpha, Beta, Omega and soon many more Daleks, Humanised Daleks were created. However, this led to the Great Civil War as the Humanised Daleks questioned and rebelled against the Daleks' orders. The opposite of this procedure occurred when the Daleks implanted the Dalek Factor into Theodore Maxtible. (DW: The Evil of the Daleks) The Dalek Factor turned Humans into Dalek servants and in some cases when they are mortally injured they can initiate a type of regeneration. (NSA: I am a Dalek)
 * Silurians and Sea Devils could create cross-breeds, even though they were similar species. The Hybrids were shunned by society, were sterile and possessed a shorter lifespan due to cellular degeneration. (MA: The Scales of Injustice)
 * In an alternate reality a Silurian-Human hybrid was created. (BBC: Spiral Scratch)
 * The Doctor once described himself as "Half-Human", but this is disputed. (DW: Doctor Who) A possibly apocryphal account suggests this was a ruse to fool the Master, involving the use of a Chameleon Arch. (IDW: The Forgotten)
 * When the Doctor prevented his regeneration by shifting his regeneration energy into his severed hand, a Meta-Crisis was caused, resulting in Donna Noble being turned into a Time Lord-Human hybrid, giving her the Doctor's knowledge (although the Doctor later had to erase her memory as the knowledge would cause her to burn up). In the Meta-Crisis, the Doctor's hand turned into a duplicate of the Doctor who was exactly the same as the Doctor apart from having only one heart as opposed to two. He also was unable to regenerate and had the lifespan of a Human. (DW: Journey's End)
 * Peter Summerfield was a Human-Killoran hybrid; he had a Human mother (Bernice Summerfield) and a Killoran father (Adrian Wall). (BFBS: The Squire's Crystal)
 * Arnold Golightly was a Human-Vespiform hybrid; he had a Human mother (Clemency Eddison) and a Vespiform father (Christopher). (DW: The Unicorn and the Wasp)
 * Adam Lloyd was the half-Human son of Samuel Lloyd and Eve. (SJA: The Mad Woman in the Attic)
 * The Raxacoricofallapatorians and their relatives from their sister planet, the Clomians, sometimes bred together; the Abzorbalovian Rebels were descended from the Raxacoricofallapatorian Huspick Degenerate. (WEB: Captain Jack's Monster Files: Slitheen)
 * When the Pyroviles tried to conquer Earth, they converted the Sibylline Sisterhood into Human-Pyrovile hybrids. (DW: The Fires of Pompeii)
 * Thomas Kincade Brannigan (a Catkind) and Valerie (a Human) produced several Catkind-Human hybrid children. They resembled kittens but could say words like "mama". (DW: Gridlock)
 * While in New York 1930 the Cult of Skaro implanted Pig DNA into humans, turning them into Pig Slaves. (DW: Daleks in Manhattan/Evolution of the Daleks)
 * Kronos was an Eternal-Chronovore hybrid. (PDA: The Quantum Archangel)
 * A Karfelon scientist known as Megelen, while experimenting with Morlox DNA, was accidently fused with it and became the Borad. (DW: Timelash)
 * The Luminus cult combined the DNA of the Sline lizard and the Aaglon shark to create the Slaag. (NA: Tragedy Day)
 * The Winders, the police force of Starship UK, were Human-Smiler hybrids. (DW: The Beast Below)
