Frank O’Connor and Rob Semsey have both shot down two of the more popular theories/speculations in relation to the unknown Spartan-like figure in the Halo 5: Guardians teaser image.
It’s not female and is not Cortana in any shape or form. So that leaves the question what is it? Could it be a playable character just like the introduction of the Arbiter in Halo 2. Or could it be an enemy? Leave your thoughts!
Update: Josh Holmes makes it even more apparent this is a new character and a male!
I think that the mysterious character is Cortana’s secret brother, dunno why but it just came into my head 🙂
