10 Deadliest Enemies Of The Stargate Universe
1. Wraith
The Wraith arose in the Pegasus Galaxy when humans were first introduced to the planets where Iratus Bugs lived. Over time, the incorporation of human DNA resulted in the creation of an entirely new species that mimicked many of the features of its progenitor. Wraiths feed upon humans, killing them in the process.
Wraiths are one of the hardest beings in the Stargate Universe to kill, as they can heal from nearly any injury by feeding (or if they've recently fed). They are also immortal, in that they don't die of natural causes and can only die with a great deal of effort or hunger.
Wraiths quickly evolved to become a dominant force in the Pegasus Galaxy, challenging the Lanteans (Ancients), who were the impetus of their creation. Their technology and ability to survive almost anything made them incredibly difficult to defeat, as the destruction of one Hive Ship meant that there were several waiting to take its place.
The Lanteans created the Asurans to try and defeat them, but in the end, the Wraith won the war. They created a shutdown code in the Asuran programming, and ultimately, they forced the Lanteans to abandon their city. When they did, they left the Wraiths as the dominant force in the Pegasus Galaxy.
