I'm fairly familiar with which Star Wars properties are/aren't considered Disney canon; I was thinking about it yesterday and realized that I can't think of a single appearance of the Chiss race in any canonical sense, aside from Legends. Do they appear in any Disney canon works, and if so, can you point me to them?
5This seems like a fair question. Don't let the downvoters get to you!– ThunderforgeAug 15, 2017 at 13:21
1@Thunderforge thanks! I never do :D Pretty dumb question on my part though, I should really watch Rebels before asking about Disney canon– Allball103Aug 15, 2017 at 13:22
14Upvoting because the negatives are undeserving imo. Just because you aren't aware of the existing works where they have already appeared doesn't make this a stupid question. Ignorance, yet knowledge.– thegreatjediAug 15, 2017 at 13:25
7@Allball103 - you aren't required to watch a show of a 100hour length to be allowed to ask questions, and having not watched it doesn't make you dumb in any way (for full disclosure, neither have I :)– DVK-on-Ahch-ToAug 15, 2017 at 13:28
2Could we use 'Star Wars canon' instead of 'Disney canon'. Wikipedia and Wookieepedia both list 'Star Wars canon'. Disney canon would be understood as this: tvtropes.org/pmwiki/pmwiki.php/Franchise/DisneyAnimatedCanon first google hit.– LudiAug 15, 2017 at 15:15
Yes - Both Chiss (and Admiral Thrawn!) are Disney canon.
Timothy Zahn's Disney Canon novel Thrawn introduces them.
Eli winced. A gift for the Chiss of the stories, that would have been a deadly insult. Thrawn was behind him, and he didn’t dare turn around, but he could imagine the expression on that proud face.
“I do, Your Majesty,” Parck said, bowing low. “A warrior reportedly of a race known as the Chiss.”
“Would I?” the Emperor sounded amused. “Certainly you’re a resource of unlimited confidence. What exactly do you offer, Chiss?”
Some relevant details from new Disney canon were summarized in Wookieepedia Chiss article.
As another answer noted, Thrawn (and his blue appearance) is also in Star Wars Rebels but I'm not aware if he's named as a Chiss there.
Since your question doesn't explicitly specify whether you meant Disney canon by "canon", I should for completeness's sake point out that Chiss are most certainly a part of EU Legends canon, in multiple books starting with Timothy Zahn's original trilogy.
Awesome! Haven't watched Rebels yet, thanks a ton. Aug 15, 2017 at 13:19
(I should have clarified, but Disney canon IS canon now. So yes, that's what I meant) Aug 15, 2017 at 13:30
2@Allball103 - yeah, I mostly added that to give Valorum a reason to vent :) Aug 15, 2017 at 13:34
1EU Legends are not canon!– ValorumAug 15, 2017 at 16:59
2Adding to this, the first appearence of Chiss in the Disney canon was in the mobile game Star Wars: Commander. Another fun fact is that the Disney chiss have pupils, wheras the Legends Chiss have completly red eyes without pupils. Aug 16, 2017 at 15:46
Thrawn is in Star Wars Rebels, which is Disney Canon. As we all know he is Chiss and retains the blue skin/red eye combo that we all know and... recognize?
2Good answer, chose DVK's because of quotes and other examples. Aug 15, 2017 at 13:25
According to Wookieepedia
The Chiss became canon when they appeared in Secret Alliances, the sixth campaign featured in Star Wars: Commander, a mobile game published by Disney Interactive1 that was released on August 21, 2014.
Also from StarWars.com - Grand Admiral Thrawn
Thrawn was a male Chiss, with striking blue skin, red eyes, and an angular face, known for his brilliant strategic mind and ruthlessness. He was determined to “pull the rebels apart piece by piece.”
2this is a good answer - if you flesh it out a bit more (ie - include some details - maybe from StarWars.com or something "official" as the canonicity of Star Wars: Commander, you may get more upvotes. You have mine because it seems this is the first new canon reference. Good catch Aug 15, 2017 at 13:26
