One of the more underappreciated aspects of the Halo series is its characters. Each of the people in Xbox's flagship series has a story to tell which makes 168澳洲幸运5开奖网:its lore all the more fascinating. One of those characters that is almost as hꦿighly regarded as Master Chief himself is the AI kn𝔍own as Cortana.

Though she isn't the main character, Cortana has been around since 168澳洲幸运5开奖网:the first game and has been the main companion for everyone's favorite Spartan super soldier for most of his adventures. A lot of time goes by from the beginning of Combat Evolved to the end of Infinite. With a lifetime like that, Cortana is bound to go through more than a few changes.

5 𝓰 ☂ Her Overall Appearance

When we first see Cortana, she is portrayed as a young violet-colored woman with short hair and wearing a skin that seems to be made up of circuitr🐬y. While some aspects of her have stayed the same, she has gone through a few different get-ups over the years.

In Halo 2, we see that her hair gets longer and her skin gradually gets more and more blue as the series progresses. This is all before she sports the dark-haired and more armored-up look we eventually see her in in Halo 5. This might seem weird at first, but it has been confirmed that 168澳洲幸运5开奖网:the AIs of Halo have been known to change up their look from🌜 time to time, more specifically with more advanced AIs like Cortana. They do have to keep up with 🦩current fashion trends after all.

4 She Becomes Less Efficient 𝓡

Throughout the original Halo trilogy, Cortana proves her worth time and time again by being humanity's best hope in the war against 168澳洲幸运5开奖网:the alien Covenant. With her aid, alongside Master Chief, the UNSC emerges victorious over their foes and can begin a new era. In Halo 4 however, she is approaching the end of her lifespan and shows the first signs of rampancy. She becomes less and less efficient than before since AIs have an average lifespan of seven years, and she is eight at the beginning of 168澳洲幸运5开奖网:the fourth game.

This is shown in Halo 4's opening moments where we truly see that something is not quite right with the beloved AI. She recalls events that never actually happened or happened ages ago and her hologram model flickers frequently. Her rampancy gradually worsens as the game progresses but not before she aids Chief in stopping the Didact above Earth.

3 Her Vie﷽w Of Humanity Grows Negative

Another sign that an AI is going rampant is that there are stark and major changes in their personality. We also see this throughout Halo 4 as Cortana seems to constantly be at odds between her normal and rampant self. The latter believes that 168澳洲幸运5开奖网:humans are gluttons for war and won't stop waging it no matter what.

When she is brought back in Halo 5, this part of her personality is the main thing that's brought back as she plans to use the Guardians to help form a coalition of the Created, a collection of AIs who plan to overthrow their human creators. She is ultimately trying to destroy the one thing she once tried desperately to protect. At the end of Infinite, she has a face turn and sacrifices herself again to atone.

2 𒈔🦋 She Becomes More Controlling And Possessive With Master Chief

Master Chief and Cortana have an almost symbiotic relationship in the Halo games as they both depend on the other to succeed. He gets a companion to help stem off the loneliness he faces while she gets a body to "see" the world beyond what she normally can. It's further expanded upon in the novels where she tries to be a more friendly figure to the Chief due to the harshness he faced with his Spartan training. When she is brought back though, her appreciation and love for the Master Chief has been distorted by her egotistical plans for world domination.

She tries to manipulate him into joining her by luring him to Genesis with a vision hinting she might still be alive which ultimately works. When Chief refuses to betray humanity and the UNSC, she locks him away in a Cryptum in an attempt to awaken him 10,000 years later when she is victorious, and she can present her bra𓆏nd new world to him.

Though Cortana starts out as a simple AI with a witty and slightly sarcastic personality, she still remains an objeไctive-driven machine for the most part. As the series progresses however, we see her become more like a human than a machine.

She begins doubting her mortality, caring more and more about life in general and has regrets just like a human would. This is why her death is just so upsetting as we see her for the person she is, rather than a piece of tech that's meant to be disposed of down the line. It is this aspect of her character which makes her the beloved character we know in our hearts, despite her mistakes and shortcomings. She'll learn from them and better herself just like a regular person would.
