The Borg cube is the primary vessel of the Borg Collective. Measuring 28 cubic kilometers in volume and carrying up to 200,000 Borg drones, the cube is one of the most powerful vessels in the galaxy. (VOY: "Dark Frontier")
Every Starfleet encounter with a single cube has resulted in heavy losses. 39 out of 40 ships were lost at the Battle of Wolf 359 in 2367, and dozens more in the incursion of 2373. (TNG: "The Drumhead"; DS9: "Emissary"; Star Trek: First Contact; Star Trek: The Prospect Chronicles: "The Burnt Child"; Star Trek: The Cantabrian Expeditions: "Catalyst, Part One", "An Innocent Time", "Devil's Cube")
In the aftermath of the Battle of Wolf 359, an alien starship appeared to be communicating with the Borg cube en route to Earth. In actuality, it was a 27th century Federation starship communicating with their away team of historians aboard the cube; a communication the USS Prospect cut off, essentially leaving the historians to be assimilated. (Star Trek: The Prospect Chronicles: "The Burnt Child")
A single cube was capable of eliminating all elements of civilization from an entire planet.
In 2372, the USS Cantabrian encountered a Borg cube, nicknaming it the "Devil's Cube", severely crippled in the Devil's Cradle by an unknown adversary. This adversary employed a harpoon-like system to breach the cube's hull and seriously cripple the cube. The cube was repaired and engaged the unknown adversary in a fierce fire-fight: one which the Cantabrian ran from. (Star Trek: The Cantabrian Expeditions: "Devil's Cube")
In late-2373, a second Borg cube was sent to assimilate Earth. The cube was detected after attacking the Federation colony of Ivor Prime. Starfleet intercepted the cube in the Typhon sector and engaged it in battle. The cube reached the Sol system before been destroyed by Starfleet forces led by the USS Enterprise-E. (Star Trek: First Contact)
In an alternate universe, the Borg cube sent in 2373 would place a crucial role by creating a turn point in the Federation Civil War. Its attack devastating Admiral James Leyton's forces defending Sector 001 and set in motion the final stages of that war. ('Star Trek: Pendragon)
Upon closer inspection, the Cantabrian away team discovered several harpoon-like weapons lodged deep within the Devil's Cube. These weapons sent a surge through the cables attached, disabling the cube and its drones.
The Cantabrian fled the attacking Devil's Cube after the cube's systems came back online, and the unknown adversary emerged again from a subspace rift. As the two alien ships battled, the Cantabrian made its escape, igniting metreon gas in its wake to either disable or destroy the enemy ships and collapse the subspace rift.
