Dr. Catherine Elizabeth Halsey
When it comes to quick-witted, steel-tongued older ladies, Dr. Halsey is most certainly one of the coolest. Halo 5: Guardians showed us a side to Halsey that puts her on the list of badass seniors. Her cold demeanor and abrasive personality conveys the strength and respect she’s due. She is a key scientific advisor of the Office of Naval Intelligence, and is best known for her work on the SPARTAN-II program, creating smart AIs like Cortana, and for developing the MJOLNIR Spartan armor.
Basically, she’s responsible for everything that makes the Halo universe so awesome! If that doesn’t impress you, she also escaped the UNSC after being convicted of warcrimes. In turn, she defected to Jul ‘Mdama’s splinter Covenant faction. Not badass enough? She also lost her arm in a struggle against Spartan Palmer. When it comes to badass seniors, Dr. Halsey is about as tough as they come.
