|“||The Ark needs unity now more than ever.||”|
|— Diana to Chancellor Jaha [src]|
Diana Sydney was a recurring character in the first season. She was portrayed by cast member Kate Vernon and debuted "Contents Under Pressure". Diana was a former Chancellor of the Ark, who plotted to seize power back from Jaha. She served one of the main antagonists of Season One, alongside Anya.
After the Culling, Diana painted herself as a voice of the 'lower classes'. She regained a seat on the council, and later with her supporters stole the Exodus ship to get to Earth. However, during the launch, it had an open service hatch, and that coupled with Mount Weather's jamming frequency, caused the dropship to crash. She and everyone onboard died in the resulting explosion.
Diana was born on the Ark. At some time in her adult life, she became the Chancellor of the Ark and she lost the position to Thelonious Jaha after he beat her in an election. After that, Diana organized a coup to try and usurp power by gathering a few guards loyal to her, including Commander Shumway and Lieutenant Graco, to overthrow the current administration and be leader again. She tasked Commander Shumway with assassinating Jaha, a task he handed down to Bellamy Blake, but Jaha ultimately survived.
Throughout the Series
Diana showcased very manipulative behavior and attitudes towards others. She was very secretive and willing to kill for her cause. Being the former Chancellor she knew more than the average citizen, especially about secret Ark programs.
Diana presents herself as someone who would look after the "lower class" citizens and the voice of reason. This however, is a facade and in truth, she is a manipulative, self-serving, power hungry person who only cares about herself. After she lost the election she plotted to take the position back by force and didn't care who got hurt in the process, including her own followers and innocent civilians. This is shown after the Unity Day bombing when she was unconcerned about the innocent lives lost and only says they should have made a bigger bomb. She was even willing to manipulate the Council into making decisions she knew the people would be upset with so she could paint herself in a more favorable light. Even at her best, Diana was condescending and ignored her own faults while pointing out the faults of others. She called out Jaha to their people about the exodus ships when Diana herself knew about it too when she was chancellor.
Diana had blonde hair with dark roots. She was of average height and had light hazel/green eyes.
Day Trip, it was revealed that she was the one who orchestrated the attempt on Jaha's life.
