[1] Lucasfilm rebranded the Expanded Universe works as Star Wars Legends in 2014 and declared them non-canon to the franchise; however in the 2017 Chuck Wendig novel Star Wars: Aftermath: Empire's End, the recurring character of B-1 (Mister Bones) is revealed to have been built from parts of HK-47 to help the fledging New Republic against the leaderless Galactic Empire, briefly taking over the droid with their "strange, hard-angle" accent.

In the time frame of the Trials of Obi-Wan expansion to Star Wars Galaxies, HK-47's artificial intelligence has transferred into a computer on a Galactic Republic cruiser that later crashed on Mustafar.

The B-1 battle droid known as "Mister Bones", rebuilt by New Republic supporter Temmin "Snap" Wexley from droid parts from a scrapyard, is revealed to have been built from parts of HK-47 in the 2017 Chuck Wendig novel Star Wars: Aftermath: Empire's End, with HK-47 briefly taking over Bones after they "glitch" and their voice "warps", causing their "strange, hard-angle" accent to return and say "COMMENTARY: I SAY WE BLAST THE MEATBAG AND SAVE YOU THE TROUBLE, MASTER".

[10] GamesRadar listed HK-47 as the 3rd best conceived character in video gaming, calling him "cheerfully insane" and saying he was "[e]asily the highlight of the [Knights of the Old Republic] series".

[18] Dakota Grabowski of GameZone listed HK-47 as the second top BioWare created teammate, commenting that he delivered some of the best lines in Knights of the Old Republic.

"[20] Matt Miller from the same magazine called HK-47 the second top AI character of the decade, commenting that if the player chose to go light-side, then "he is a perfect counter to your heroic actions".

The magazine noted that his personality and humour "[held] a mirror to Revan's dual history with both sides of the Force", saying that he highlighted the overarching Star Wars theme of everyone having both good and evil in them.

[23] GameSpy's Mike Sharkey called HK-47 a noticeable omission from the 2011 Guinness World Records Gamer's Edition's top 50 video game characters.
