Will they change the Jem'Hadar's appearance?

[Yukaphile]

And if so, how badly will they butcher and mutilate their looks in Star Trek Galaxy?

[J!!]

Why does it matter?

[Yukaphile]

I'm a canon purist. Don't change their looks for no reason.

[Independent George]

I know nothing of Galaxy, but... since they are an engineered servant species, can't you just handwave it away that it's a new generation created by the Founders?

I'd be surprised if the Jem'Hadar change in any fundamental way (I haven't been following gossip, are they going to be in there, or is this just speculating?) - they were a pretty comprehensive makeup already, with tons of detail, individual variations, the whole works. Don't get me wrong, I love Worf-era Klingons, and I'm not particularly fond of the newbies (although I don't mind them much), but I can see how the producers felt there was room to jazz them up. The Jem'Hadar were devised when the Trek tv design/makeup department had been honing their art for years already, they were born jazzed up - I'd expect to see tweaks like the Borg got for First Contact, more intricate (more expensive) armour, maybe a bit more emphasis on the alien features to their faces, but pretty much the same thing.

Mind you, but for all being bald I feel like the 'new' Klingons are 'pretty much the same thing' as well - the skin tones are darker and the makeup's been exaggerated, but slap a wig on them and I really think it'd just come off as "we've got a budget now" rather than a 'redesign'.

And y'know, if they did get adventurous with the Jem'Hadar - off the top of my head, I'm thinking those springy leg things Farscape used for Namtar would be pretty cool, if they were willing to spend what they'd have to to wrangle half a dozen extras in the damn things every day on set - it wouldn't be the worst thing in the world. Like George says, they're engineered anyway - they had that short-lived thing of there being new 'Alphas' being bred to replace the Gammas - so now the Dominion's had time to properly study all the DNA they've no doubt sneakily collected from all the Alpha Quadrant species they never had access to until recently, why wouldn't they toss in a few upgrades?

They will look "edgy" and "new" and "modern", which means plastic and without any motion on the faces, lots of gratuitous spikes and fangs, and they have to wear multicolored spotted contacts now.

Their guns look like the bolt caster from XCOM 2's alien ruler DLC, and their polearms have at least 6 extra blades and spikes in objectively stupid positions, some in places that can only harm the user. They now will commit suicide if they fail to succeed on a mission the first time, which happens a lot because they're so literal that they obey the Founders' words to the letter, resulting in multiple failed missions every episode.

They also now have a vocabulary that consists entirely of "Victory over the inferiors is life!" and "Make the Dominion Great Again!" and "Pepe Founders glory!", and wear overcomplicated spikey red armor where the spikes on the chest are in a pattern that spells out MAGA. The writers go on and on about how subtle their allegory for Trump is, even though Salome Jens has been replaced by Alec Baldwin, who's constantly doing his Trump impression while wearing a red hat.

Everybody left of center is still expected to praise this as pure genius and everybody on the right to hate it for daring to include characters who aren't white men, though, because that's the world we live in now.

They made minor changes twice just during DS9.

I can see them changing it a lot more dramatically though, if only to make them visually distinct from the Krill over on The Orville.

[Yukaphile]

It's stupid, that's what it is.

[chaos42]

well since their all vat grown soldiers i think that its possible they can make up any reason to change how they look and fix it later so its not impossible to fix if they do screw this up

[Nessus]

I think MissKitty is on the money.

I can see them doing a version of the makup that's more exaggerated, but basically the same design on paper. Maybe make the dinosaur head ridges project more, give them a more contrasty paint job with more specular variation. Definitely give them custom teeth this time. They'd still look enough like the familiar JemHadar, just a bit "extra", y'know?

It's the costumes I'd expect them to really go to town redesigning. Those PJs they wore back in the nineties were very... nineties. I wouldn't begrudge the desire to redesign them, but I would of course want a new design to look good in its own right.
