The Martians, also known as the Invaders, are the fictional race of extraterrestrials from the H.G. Wells novel The War of the Worlds. They are the main antagonists of the novel, and their efforts to exterminate the populace of England (and later the Earth) and claim the planet for themselves drive the plot and present challenges for the novel's human characters. They are notable for their use of extraterrestrial weaponry far in advance of that of mankind at the time of the invasion, 1898.
Little about the Martians is definitive, the story being told by a first-person narrator.
The Martians are described as octopus-like creatures: the "body" consisting of a disembodied head nearly four feet across, having two eyes; a v-shaped, beak-like mouth; and two branches each of eight 'almost whip-like' tentacles, grouped around the mouth, referred to as the 'hands'. They reproduce asexually, by "budding" off from a parent. Internally, the Martians consist of a brain, lungs, heart, and blood vessels; they have no organs for digestion, and therefore sustain themselves on Earth by mechanically transfusing blood via pipettes from other animals, notably humans. The ear, a single timpanic membrane located on the back of the head, is believed "useless" in Earth's denser atmosphere. The Martians arrival on Earth is aboard large, cylindrical spacecraft launched from some kind of immense cannon on Mars, and their chief weapon of war is the invisible 'Heat-Ray' that produces a white flame that consumes any organism it touches. This is mounted on an articulated arm attached to the front of the tall tripod, called a 'fighting-machine' in Wells' novel, which travels across the landscape destroying humans and their habitat. A secondary weapon, the "Black Smoke," is a toxic gas released from canisters launched at a distance from Bazooka-like tubes, referred to in the novel as a "gun," which kills humans and animals alike; it is rendered harmless by Martian high-pressure steam jets and water. Mention is also made of a Martian aircraft, but it is hardly seen, except to possibly spread the deadly Black Smoke from above over a wider area.
