Cobra

The Cobra is one of the three super-heavy skimmers of the Eldar, the others being the Scorpion and the Lynx. Apparently, in Eldar mythology, the cobra was the brother of the serpent but a short-tempered, fickle ally, to whom the serpent turned to for aid only during the darkest days of the War in Heaven. The Cobra is best compared to the Shadowsword, a titan killer that uses its D-Inpailer to rip large chunks of the enemy into the void.
The Cobra uses the same chassis as the Scorpion, this means that the super-heavies of the Eldar are stupidly fast and agile both in fluff-terms and on tabletop. Other than its stupidly humongous D-cannon which makes even void shields collapse on themselves like wet tissue paper, the Cobra also comes equipped with a titan-grade Holo-field as well as secondary armaments such as a Bright Lance, Eldar Missile Launcher, Scatter Cannon, Shuriken Cannon or Starcannon. Some Cobras are also upgraded to include Star Engines and/or Vectored Engines for improved handling and speed.
