Dark Henge are Esmeraude-shaped statues from Sailor Moon R that the Black Moon Clan planted at the Negative Point to raise the Dark Gate. Several were needed at once, and each grew with Dark Power until the gate could form.
Appearing solely in Sailor Moon R, the Dark Henge were carved into the likeness of Esmeraude and served as the machinery behind the Dark Gate. Esmeraude set them at the Negative Point to open that gateway, though a single statue was never enough; she required a whole set working together to make the passage take hold.
Once positioned at the Negative Point, the statues swelled with Dark Power and began forming the gate, with a Droid posted to guard them. The Sailor Guardians repeatedly disrupted the scheme. Whenever a guarding Droid was beaten, its Dark Henge appeared to self-destruct, shrinking and venting Dark Power before toppling and breaking apart. Chiral and Achiral fielded a pair of far larger golden versions that towered over Chibiusa's elementary school after sprouting up in almost no time, yet those too shattered upon the brothers' defeat.
Esmeraude was the primary user, with Saphir credited as their maker and Chiral and Achiral deploying their own oversized pair. After Esmeraude died, Prince Demande abandoned the statues entirely, choosing instead to draw on Black Lady's power in the present through a large crystal, with Black Lady channeling the Dark Power directly, which left the Dark Henge unneeded for the new gate.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....

Saphir is credited as the maker of the Dark Henge, which Esmeraude then set up at the Negative Point.
Each Dark Henge is guarded by a Droid, and when that Droid is defeated, its statue self-destructs, shrinking and venting Dark Power before toppling and breaking apart.
Chiral and Achiral fielded a pair of oversized golden Dark Henge that towered over Chibiusa's elementary school after sprouting up almost instantly, though these also shattered once the brothers were defeated.
After Esmeraude died, Prince Demande abandoned the Dark Henge entirely, choosing instead to draw on Black Lady's power directly through a large crystal, which made the statues unnecessary for the new gate.
