I'm reposting this because the list is now complete.
Edit: Except Garrett? Maybe she won't get one?
Fuzz (The Maniac)
Fuzz can switch from hysterical laughter to filter-free anger at the drop of a dime.
He's a fun-loving guy until he isn't. Just don't suggest anger management sessions to this Section 31 operative.
Melle (The Lover)
While most Deltans take an oath of celibacy upon joining Starfleet, Melle uses her irresistible magnetism for Section 31's benefit. After all, she's in a league of her own.
Zeph (The Machine)
Mech life ain't just about brute force. The human Zeph lives, works, and everything in between, inside his mechanical exoskeleton, drawing out the right tools in his work as a Section 31 operative.
Quasi (The Enigma)
No one's ever met a Chameloid's true form before, perpetuating their myth-like status as they never show their real appearance, which suits Quasi perfectly as a member of Section 31. He's disinterested in the delusion of "utopia" and most other things, especially you.
Alok Sahar (Mastermind)
Alok Sahar is a strategic mastermind who leads a special team of Section 31 operatives. Sahar is driven to make amends for actions in his past by serving the greater good, which involves tracking down and recruiting Emperor Philippa Georgiou for a covert mission.
Philippa Georgiou (The Emperor)
Unable to return to the Terran Empire, Emperor Philippa Georgiou lives under a new alias as owner of The Baraam, a nightclub operating outside of Federation space.
That is, until Section 31 enlists her to help protect the Federation while also facing the sins of her past.
This makes Section 31 sound like Oceans 11.
