The Borg BO in KA is a Male Sci Officer. There's three problems with getting it though, one is that finding a group and getting past the first Space part is very difficult for most groups unelss you get lucky and have a group of fully specced escorts who know what their doing and how to do the first space part.
Second to get the accolade for the Borg BO is very deep inside the borg caves, and while you don't have to complete the STF to get it its far enough in you might as well so having agroup stick together that long is tough to find.
And lastly, the Borg BO looks like an actual Male Borg in the game however unlike the female one on the C-store you can not customize it (hopefully that will change) like the Photonic/Hologram BO so its not as "cool" as the one the C-store but still worth trying to get if you can manage the annoyance that is the "Borg Build Up" in the first part of KA.
(And I am not saying KA is impossible but it does need to be changed unless there is some easier less stress free way to get past the first part that I and most people are unaware of)
