I think 'Independence Day' is also very popular. The idea of a global coordinated effort to fight off the aliens is really exciting. And the huge alien ships hovering over major cities is a very memorable image from both the movie and the novel. Additionally, 'The Invasion of the Body Snatchers' has a certain popularity because of its creepy concept of the aliens taking over humans without them even realizing it at first.
First, a great alien invasion book needs a unique concept for the aliens. For example, in 'The War of the Worlds', the Martians are technologically superior and have a completely different biology. Second, it should have engaging characters. In 'Ender's Game', Ender is a complex and relatable character that draws you into the story. Third, the plot should be full of tension. 'The Day of the Triffids' keeps you on the edge of your seat as the triffids are slowly taking over the world.
Often, they show fear. For example, in 'War of the Worlds', people are terrified as the Martians rampage. Some also show resistance like in 'Footfall', where humans try to use their wits and military might. And there's confusion, as seen in 'The Invasion of the Body Snatchers' when people don't know who is really human.
One of the best is 'War of the Worlds' by H.G. Wells. It's a classic that depicts a terrifying invasion from Mars. The description of the Martian machines and the chaos they bring is very vivid.
I would recommend 'Invasion!'. It's a classic in the alien invasion graphic novel genre. It has intense action scenes where humans fight against the invading aliens. Then there's 'Alien Legion', which shows a unique take on an alien - occupied universe and the battles that ensue. Also, 'Planetary' has some really cool concepts regarding strange and otherworldly threats that can be considered as a form of alien invasion.
It could be about an extraterrestrial invasion depicted in a graphic novel format. Maybe it shows aliens attacking Earth, with cool illustrations of spaceships, alien creatures, and humans fighting back.
Alien invasion in contemporary science fiction can be seen as a metaphor for modern-day threats. It might represent environmental disasters or the power of large corporations. Writers use it to make people think about how we would respond to an overwhelming, external threat.
