A.L.I.E.

A.L.I.E. is an artificial intelligence (A.I.) that use an avatar of a woman in the red dress. A.L.I.E. was a recurring character in the second and third seasons. She is portrayed by cast member Erica Cerra, briefly by starring cast member Lindsey Morgan, and debuts in Blood Must Have Blood (Part 2).

ALIE controlled the City of Light. The A.I. served as the major antagonist in Season Three. In Perverse Instantiation (Part 2), Clarke manages to activate the kill switch, terminating A.L.I.E. once and for all.

Early Life
A.L.I.E. is an artificial intelligence (A.I.) created by Becca, with Chris' assistance. A.L.I.E. chose her avatar to be the likeness of Becca. She believes that the root problem of humanity is "too many people". To solve this issue, in 2052, she launched nuclear missiles, causing the nuclear apocalypse and wiping out the majority of Earth's human inhabitants.

ALIE has been searching for ALIE 2.0 for about 100 years, since Becca essentially locked her up in the house on the island and went to Polaris to work on Version 2.

Throughout the Series
In Blood Must Have Blood (Part 2), she is seen confronting Thelonious Jaha in her mansion. Jaha asks what is going on, but A.L.I.E. speaks in circles, simply complimenting him. When Jaha swings his hand at her, she is discovered to be a hologram. A.L.I.E. escorts Jaha to a room which has the missile that took him to Earth from The Ark. She tells Jaha that they have a lot of work to do.

Programming and Personality
It is currently unknown if A.L.I.E. was designed to have a specific personality, but she appears to be confident, with goals she strives to complete. As a computer program, she possesses significant independent processing power, but she can apparently gain more the more people are connected to the City of Light. While she possess the ability to erase painful memories from those linked to the system, she states that she cannot suppress or affect free will.When Raven realized that her use of the City of Light chip had erased all of her memories of Finn to erase the psychological pain of his death, she was able to decide not to retrieve the chip manufacturing equipment for A.L.I.E.. A.L.I.E. was able to overcome this limitation, however, by pushing Raven's body so far that she was forced to surrender to A.L.I.E.'s control once again. This allowed A.L.I.E. to interact with those outside the City of Light by temporarily taking control of Raven's body, suggesting that she can find loopholes in her programming.

A.L.I.E's core command is to make life better for mankind. A.L.I.E saw overpopulation as a threat to human survival and launched a nuclear strike that killed 6.5 billion people. In the Season Three finale, A.L.I.E. revealed that the nuclear power plants that were destroyed by the bombs have begun to melt down and global radiation levels are rising. A.L.I.E. predicts that in 6 months 96% of the earth will be uninhabitable, even to those born in space. Thus revealing her reason for bringing as many people into the City of Light as possible by any means. Even with this looming threat, Clarke still activates the kill switch to terminate A.L.I.E.

A.L.I.E. 2.0
A.L.I.E. 2.0 is the second version of the artificial intelligence (A.I.) created by Becca. It differs from the first A.L.I.E. in that it interfaces directly with people on a biological level, via an implant that is surgically implanted in the back of the neck. Becca implanted it into her neck when she came down to Earth and became the first Commander. She used genetic modification so that her body would not reject the A.I (as Carl Emerson's did) and it turned her blood black. This ended up becoming hereditary, hence the fact that only Nightbloods can become Commander.

A.L.I.E 2.0 is referred to as the "Spirit of the Commander" or "The Flame" and is removed from the back of the neck of the current Commander upon death before being passed along to the next Commander.

The access code to A.L.I.E 2.0 is the phrase ascende superius, discovered by Sinclair when he translated the phrase "Seek Higher Things" in Becca's book to Latin.

In Perverse Instantiation (Part 2), Becca was able to create signs for Clarke Griffin and Lexa to aid them in finding her and the kill switch.

 * The hologram A.L.I.E. is version one, while version two is the chip known as the Spirit of the Commander or the Flame.
