Can we get Nico Okarr at all?

Returning to the originally posted topic, you don't really want Nico. I have him, and from this experience:

1. His breath is worse than Qyzen's.
2. He shows up to work late, and never sober.
3. Always lets everyone know about his chemical dependency by asking if there will be a cantina.
4. Subsequently reminds everyone about his chemical dependency after the fact by saying he'll be in the cantina.
5. There is more dirt under his fingernails than on the ramp leading into the ship tracked in by Qyzen.
6. He comes back empty-handed from missions, but it could have been worse. He doesn't know how, but could have.
7. When he says "Wasn't me," he's not talking about having shot someone.
8. You will be jealous of his hat.

I'm sorry, but that is not the case. I did the quest chain for HK on a Republic character and then immediately unlocked the droid on an Imperial character.

Then I might be bugged, I can pay the unluck on my Imperial characters, but my republic ones it tells me I need HK...

I did pay with cartel coins instead of forking over 1 mil. Don't know it makes any difference.

No HK-51 is free to all subscribers on any account they make cause Section X opens at lvl 50 but if you are F2P or Preferred you have to buy the Access Authorization: Section X and you can either buy it for one toon or all accounts. It also allows f2p and preferred to get HK-51 but as a subscriber you don't have to do this. I should know I've done it several times now nor have I ever payed 1 million for HK-51 either. I just go back to Section X on whatever toon and do the mission to get him on it. I don't even understand what the unlock is for cause once I got HK-51 on my main the legacy thing said he was unlocked imp side but a locked symbol appeared on the pub one it didn't even let me unlock it so I don't understand why it's even a legacy perk when it's useless... Also I just assumed the unlock did nothing any cause I'm not sure what I am missing but every toon I have done HK-51 I go to Section X and do the mission.

Yes, you can get him. He's an Alliance Alert Mission. The only thing the Sub reward did was provide Early Access via a token. You Will get him

You don't get the alert if you didn't qualify - the Early Access to him was only added because they hadn't been clear that you'd need to finish the story before you get him.

1) Veteran players are all swimming in more companions then we can ever use now days.

2) Nico was a one time available, special promotional item, given to players who subbed in advance of KoTFE release. This is written right into the terms and conditions of the KoTFE promotions. He's not a primary companion granted to any player who simply does the chapter to obtain him.

3) If you could not be bothered to meet the terms and conditions to obtain Nico, leave the thread. You have ZERO rights to Nico.

NO you cannot. The token was to fix an oversight in their original terms and conditions. In other words, it was a gesture of good will by the studio for players who qualified to obtain Nico, because they were not clear up front that he was walled off behind a KoTFE chapter.

I'd assume for the achievement sakes there will be a few more chances in the future to obtain him by being subscribed, especially when they run out of HK-55 themed junk, it's like rock bottom with May being retarded and giving ship droid companion customization as rewards.
