[RPG] How to replicate this effect of the Infinity Gauntlet using official material

dnd-5e

I am a GM searching for some means (spell, magic item, artifact, etc) of replicating the power granted by the notorious Infinity Gauntlet as depicted in Marvel's Cinematic Universe. The effect I'm searching for in the game I am going to run as GM isn't "demicide" but is (if anyone recognizes my name and will be in my game spoiler below):

targeting 100% of certain species in the world where my game is set with something like the 6th level spell "Disintegrate".

The 9th Level Spell Wish does not seem to suffice due to this clause in the rules for Wish:

You might be able to achieve something beyond the scope of the above examples. State your wish to the DM as precisely as possible. The DM has great latitude in ruling what occurs in such an instance; the greater the wish, the greater the likelihood that something goes wrong.

Emphasis added.

I'm looking for something reliable, not a monkey paw that Wish seems to function as when anyone attempts to use it for effects of this scope.

Something that ties into established D&D lore rather than "oh yeah, it's like the movie, but in D&D".

If there is nothing even remotely like the Infinity Gauntlet in any official D&D 5e material, or Unearthed Arcana, then are there any official rules or guidelines on expanding the scope of a spell like Disintegrate to target massively large numbers of targets? I could extrapolate from there.

CLARIFICATION: it doesn't have to have "collect sub-components" as the Infinity Gauntlet needed Infinity Stones to be collected from all over the universe. The important part is if there is already anything or anyone in DnD5e official that has such power.

The closest would be: The Infinity Gauntlet

Its your world - if you need an Infinity Gauntlet, make an Infinity Gauntlet. Obviously, you can rip-off Marvel as much or as little as you want (providing you don’t infringe their IP, which you won’t do unless you publish it). Infinity codpiece, anyone?

It would clearly be an artifact so you can look to existing artifacts for inspiration starting on p.219 of the DMG but you can give an artifact whatever powers you want:

An artifact is a unique magic item of tremendous power, with its own origin and history. An artifact might have been created by gods or mortals of awesome power. It could have been created in the midst of a crisis that threatened a kingdom, a world, or the entire multiverse, and carry the weight of that pivotal moment in hi story.

Some artifacts appear when they are needed most. For others, the reverse is true; when discovered, the world trembles at the ramifications of the find .
