30MF DLRSkeleton

I'll just lead with this: These guys are awesome. I love this kit to bits.
Two models in one kit with a set of equipment and ring parts to equip other 30MF armor kits, while also being subtle enough to work as skeleton props.

They're named "DLRO" because that's the name of the world that the setting is on. You can consider it a "neutral faction" name for wildlife and monsters.
It's not really an acronym (that we know of), but in katakana symbols, it's pronounced "Durō", which can phonetically relate to pretty much anything and you can read a ton into the various Asian symbol types that match the pronunciation, for hidden meanings.

Skeletons don't have an element, they have a calcified white core (replaceable).

Aesthetics:
Both kits have transparent beady red eyes.
At a glance the skeletons look like they're human bones, especially when looking at the teeth, however upon closer inspection, you'll find lots of mechanical lines, rivet holes, and joint pins (insinuated). The skull itself has a nice integrated seamline that mimics the soft spot sutures that we have on our own skulls, but with more of a machined look to them.

While it's definitely a simplified skeletal structure, such as only having four rows of ribs, it is surprisingly anatomically accurate, with clavicles, scapula (shoulder plates), the forearm radius/ulna (as one piece) and even fibula (side shin bone). There's a two part spine as well as a molded-in spine on the back of the ribcage.

The most human looking part is definitely the skull with 20 teeth, an opening jaw-bone and its nasal cavity (vomer).

Overall, a really impressive looking skeleton model.

Mechanics:
Despite having a lot of joints, its articulation is simple, even compared to a 30MF Silhouette. The individual skeleton has an excellent ab crunch (he can get his knees behind his ears!) and a lot of neck movement, but it's somewhat limited in range.

The limbs have single joint bends and are just 'fine', while the ankles are a simple ball joint in a socket, with pretty limited movement. The overall shoulder and hip movements are pretty good, so even though you'll struggle to fine-tune poses, there is a lot of range to take advantage of.

Compatibility:
The skeletons themselves, are self-compatible. That means they have a lot of 3mm hard points that you can connect stuff onto, so if you have more skeletons, you can combine them into various bone monstrosities.

One of their advantages is the ability to mount 30MF armor, but here's what you CAN'T equip:
Mouth piece - No lower face parts
Chest - Only a single hole for a core, you're not meant to equip dual peg chest pieces
Back - There are tons of back hole options, but no support for "HG" style dual pegs, such as the ones the Knight Options armor set uses
Waist, front - No loincloths, he lets it all hang out
Arm Guard - While there is a hole, it won't fit standard armguards/bracers
Calves - No holes on the side of the shins
Feet - No holes on the front

Item Shop 3 does have a single peg chest connector piece, for hanging chest plates on a rack, so you can technically use that to attach a chest piece, but it sticks out significantly. It's easier to just blu-tac a chest piece on, if you need to. Alternatively you can use 30MM chest pieces, like the Spinatio Knight chest armor, completely naturally.

There is a pegged ring set that you can attach other armor onto and there are additional hard points that a Silhouette doesn't have, on the scapula, back and upper thighs. He even has two butt holes for extra 3mm pegging action.

Equipment:
2 Pairs of hands (each) - Holding and spread out open hands
1 Cleaver
1 Machete
1 Stiletto Blade
1 Staff - The three weapons can be extended with the staff for a makeshift spear or halberd
1 Heavy Chain - Wraps around the chest and can carry 3mm pegged stuff
2x 3mm pegs

Conclusion:
Like I said, I love this kit. Despite its limitations, it's awesome and while it comes in a nice bone color, it's perfect for painting and weathering. You want a Terminator skeleton? Paint it metallic! You want D&D skeletons? Keep them as they are, as fidget toys on the table. Great for diorama purposes and more, a real 'sleeper' hobby kit.
