Personally, its Locke for me.
You forgot Halsey 
Me, it’s Buck and Linda 
Buck and linda
You just forgot Master Chief…
Toss up between Fred and Kelly for me… but went with Kelly since Fred is more or less a master chief clone.
Vale FTW
Going to press Buck…Oh, Arbiter, I haven’t seen you…press the Arbiter

I think he did it on purpose 
QUEEN KELLY-087
Kelly <3
The choice is between Linda and Kelly and it is a hard one, but I ended up going with Kelly since I have a feeling I know how they’ll portray Linda already (silent badass sniper) while Kelly is much more open to interpretation.
It’s all about Buck! BAM said the lady!
Playable: Fred
Unplayable: Halsey
Arbiter
I can’t decide between Buck and Arbiter. If there was like a meld of both characters… ArBuckter… <.<
Blue Team as a whole but especially Kelly. I adore the Spartan IIs, don’t care for any Spartan IVs except Buck.
Can we just pretend Blue Team is one character? I don’t like picking favorites 
Arbiter for me.
The Chief
I think Locke’s character is going to be the most interesting. Guys, remember, he is the leader and the secondary main character for a reason. 343 is most definitely going to flesh him out the most as he explores Chief’s psyche and tries to understand his motives on his manhunt mission.
I think we are going to see some pretty great character development for him (as well as good characters that 343 have surrounded him with, not the least of which is Buck).
