She is such a snarky bitch and I absolutely love it. Dr. Halsey is smarter than every single person in any room to have ever been built. What I adore most about her is that she knows that fact and intimidates everyone with it. Her intelligence is more vicious than any MAC cannon could ever be. No matter if you're the captain of the galaxy's most powerful warship, a Spartan commander, or one of the deadliest radical Sangheili leaders, you will never be safe from her intellect.

This was a fantastic list and I'm glad to watch it. Really makes me appreciate how 343i portrayed her in Halo 4, even despite her controversial appearance in the then-ongoing Kilo-Five Trilogy. However, you are omitting the genesis of her proper visual introduction in Halo.

"Your primary objective? Commander, are you a puppet or a Spartan?"

Sword Base's ending in Reach was an amazing scene not only witnessing her care for her Spartans, but so quickly snapping at the third generation Spartans she previously had no real idea about. Then came her flair for the dramatic. Dr. Halsey is never one to disappoint, is she? Well, morally, of course, she's atrocious, but damn if she can't make you excited to watch her be the alpha bitch.
