The Massive

"Noticed that? This is a flagship for the Irken Empire. They called it the Massive. Can't you believe it's so big that it could transport the most importent people in the Irken Empire?"

--Su Ji-Hoon, Coming in Peace

The Massive is the appropriately-named giant flagship of the Irken Armada, and is escorted by many ships at all times. It is always surrounded by smaller ships, except in Invader Zim episodes, "Backseat Drivers from Beyond the Stars," where the Massive was dragged away from its fleet through a hacking by Zim; and "The Nightmare Begins," in the ending where Zim reported in to the Almighty Tallest.

History and Design
The Massive was commissioned by Tallest Miyuki and designed and built by Vortian Engineers (particularly Prisoner 777) long before their conquering by the Irkens.

As the lead ship of the Armada, the Massive is constantly occupied by the two leaders of the Irken Empire, the Almighty Tallests. From the bridge, they monitor all of the machinations of Operation Impending Doom II and Operation Impending Doom III.

The main chamber, where Almighty Tallests Red and Purple spend most of their time, is equipped with a large screen and with a long-distance communication system, which the numerous Invaders and Zim himself make use of, contacting the Tallest to inform them of their progress in conquering their respective planets. The frigate is run by the Navigators, who are also in charge of communications. The Massive is a gargantuan, one-of-a-kind battle cruiser, and is the largest in the Irken armada, being even larger than some planets. Its outward appearance appears to be a combination of the Viral Tank, Ring Cutter, Spittle Runner, and Ripper's designs. The sheer scale of the vessel itself is meant to strike fear into the hearts of those who would resist the Empire, and the thick armor, powerful weapons, and large accompanying fleet make victory all but certain. However, according to The Resisty and a sequence in an Invader Zim episode, "Dib's Wonderful Life of Doom," the Massive possesses one structural weakness: the side pods filled with the Almighty Tallest's snack foods. With enough firepower, this side-pod can be ruptured, releasing the snacks and causing great distress to the Irken leaders. An additional weakness is witnessed in its vulnerability to long-distance hacking and hijacking.
