[HK-51: How do you get him on hoth]

 

[spoiler ALERT BELOW]

 

This part IS theory but it makes sense. In the flashpoint "The False Emperor" the Republic and Sith must defeat Darth Malgus. in this flashpoint malgus rebuilt HK-47 again and like foundry you have to beat HK-47 after this final defeat its most likely you recieve his remains. This flashpoint is Level 50 for both the republic and sith.

 

 

My theory and conclusion

 

all these that i mentioned above make sense in the way they fit each other foundry led to hk remains being built by malgus only to have you fight him again at the level 50 flashpoint since malgus is gone and the most powerful hk assassin droid laying scrap who will take the reamins? you of course! you then go to hoth where you find someone or something who knows how they can use the "hk parts" this will then have you travel around hoth to get the final pieces to make the bonus companion.

 

I would just like to let everyone know, I beat The False Emperor yesterday on my level 50 and it does not link to HK-51 in any way.
