There are so many possibilities for companions. I have a question though: will there be advisors like Cullen & Josephine, who are stationed on our ship/main colony, but play a major role in our story as a pathfinder and/or will be LIs? They said they use DA:I as a pattern (if i remember correctly, if not: you never read this xD.) so what will we get? Or will there be the typicial ME-flair with the 7 squad members?
As squadmembers/companions (attention: stereotypes ahead) i like to have a female turian or salarian, class doesn't matter for me here. A turian with a cheerful personality like Talis' and a Salarian with a quiet sarcastic nature like Morrigan would be awesome. But i think a stern, rightous, battlehardened and loyal personality like Cassandras' or Brienne of Tarths' would be fine, too.
I am fine with Drack as a male krogan (would be quiet interesting, if he is the untypical krogan, cowardly, sensitive, nerdy and gentle who wants to find courage and his fighting spirits. Something like self discovery as a theme). Or he is the machoman, who has to be tamed oO.
I have the feeling that we'll have 2 human companions (male or female) or a human male and a female asari. I don't know why, but this space cowboy n7 guy from the teaser reminded me a little bit of James Vega (but i can't say why oO). Maybe he is a mix between Anthony DiNozzo from NCIS and Roland from Stephen King's The Dark Tower. I can live with a Zaeed - like type, too. Or with a good old Clint Eastwood like mentor guy. Or we'll get a Dorian comeback (other name, other background, same character traits). Or a human Javik. Or....
Cora, hm. A greece name for maiden or virgin. Could be a soft and gentle person like Liara or Tali - or a second Morrigan/Morinth as ironic counterparts. Or a manipulative ice queen biotic. Or hot tempered, self confident, brash & direct, but very observant and emotional.
"Cora" could be a human female, a female asari and i think it could fit a female turian as well. A female turian with biotics? Why not
Is something special, i think. And different is always interesting.
A quarian headhunter/ scavenger/ engineer/ treasure hunter/sentinel/ex-soldier would be interesting. But male. Personality? I don't know, but it has to fit in the squad. He could be a badass, a lonesome warrior, a gentleman, a leader, a slob or a cowardly loudmouth, who just barks, not bite. Or has a strange codex for a quarian. Maybe he got exiled from the fleet or something like that.
Would be quite funny if we discover, that in the andromeda galaxy male asari exist or the counterparts to the asari as males.
As new species, besides the Remnants, why not Ovavores or Raloi. Latter ones got the chance to meet up with the asari (i walked around the spectre room on the Citadel in ME3, as the news said this). That was after the asari councel president refused to be part of the rescue team for earth. That would be quiet interesting. Other natives from Andromeda, that we never heard off before would be nice, too.
Sorry for my bad english :/.
