Wraith civil war

From SGCommand

"For the first time since the dawn of our race, there are too few of your kind to feed the waking Wraith. This has resulted in civil war. Hives are forming alliances. The strong are attacking the weak."

—Michael Kenmore.

The Wraith civil war was the name given to a conflict that raged among the Wraith hives after the Battle of Atlantis when the race believed that the Ancient city of Atlantis was destroyed and, thus, their only hope to find a rich new feeding ground was over. (ATL: "The Siege")

With the Human population of the Pegasus galaxy having yet to sufficiently repopulate since the last great culling 150 years earlier, the numerous Wraith hives engaged in active conflict with one another to secure what precious few habitable Human worlds of the Pegasus galaxy were available. (ATL: "The Lost Boys", "The Hive", "Allies")

It is unknown as yet how the war with the Asurans has affected this conflict. The Wraith have been known to unite against common enemies, but as the Asurans have begun targeting humans and hoping to eliminate their food supply, this may exacerbate the already volatile situation. (ATL: "Lifeline", "The Seer")

Todd's faction in the war came into conflict with another faction who decided to use one of his feeding grounds. A Hive Ship under Teyla's command arrived and she ordered the enemy hive destroyed and a Dart attack launched in order to cause as many Wraith deaths as possible. In the battle that followed many of her Darts were destroyed and her hive ship lost some of its weapons and was losing the battle until a Puddle Jumper flown by Colonel Sheppard launched drones into the bottom of the enemy hive causing a lot of damage. Teyla's hive ship destroyed the enemy hive easily after that scoring a victory for Todd's faction. (ATL: "The Queen")

Later, a hive ship is enhanced by a ZPM by Kenny at the orders of Todd, but Kenny mutinys, kicks Todd off the ship, and breaks away from Todd's faction to presumably set out on his own and use his new hive ship to overwhelm the rest of the Wraith in the civil war as the ZPM powered hive ship is more powerful than any other hive ship in existance and is nearly invulnerable. To stop Kenny, Todd turns to the Atlantis Expedition for help and sides with them in stopping the hive. The hive ship is ultimatly destoyed over Earth by a nuke snuck on board by Lieutenant Colonel John Sheppard. Todd remains a prisoner on Atlantis and it is unknown who takes over command of his faction now that Kenny, his former second in command is dead and he's a prisoner. (ATL: "Enemy at the Gate")
