Who could recommend a novel about the protagonist's powerful country transforming Mars at the same time and an alien invasion?

There could be an alien race that has a very different ideology from the people of Remnant. For example, they believe in a survival - of - the - fittest concept at an extreme level. Their leader, who enforces this ideology and leads the invasion, would be the main antagonist. RWBY would have to oppose this leader's cruel ways and protect their own values.

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.

Some animals would hide. Mice would scurry into their holes and stay there until they think it's safe.

The novel I recommend to you is 'My Moon Base Is Exposed.' Zhao Yu, the protagonist of this sci-fi space-time travel novel, built a base on a barren planet. Worried about the threat from an unknown civilization, he hollowed out half of the planet and built a star annihilation cannon that could destroy the planet. He also built tens of thousands of fully intelligent robotic dogs of various forms, such as the defensive robotic dog Door God, the detection and collection robotic dog Xiaotian, the combat robotic dog Nezha, and so on. He set up defenses around the base and could attack enemies that might come. Zhao Yu also discovered the ability to travel between Earth and the other worlds. He became the person at the forefront of immigration policy, wanting to make his planet the center of the Federation and fight against other planets. I hope you like my recommendation. Muah ~

I recommend "The Age of High Martial Arts: Humans Must Survive." This was a fantasy novel from the East. It described the appearance of the World Gate on Earth. From then on, the era of cultivation began on Earth. 60 years later, the alien race invaded, humans suffered a crushing defeat, and Earth was destroyed. However, the heavens turned. Li Lin returned to his high school days. At this time, there were still ten years before the appearance of the alien race…Growth! Don't be reckless!" I hope you like my recommendation. Muah ~

The key elements usually include powerful aliens with advanced technology, human resistance and strategies to fight back, and maybe a doomsday-like setting.

Arthur C. Clarke has penned stories that touch on alien invasion themes. His scientific knowledge and imaginative ideas blend well in his short stories, presenting different scenarios of how an alien encounter or invasion might occur and the consequences that follow.

One possible plot could be that aliens invade Hogwarts. They might be attracted by the powerful magic there. The students and teachers would have to put aside their differences within the wizarding world and unite against the alien threat. Harry Potter and his friends could use their knowledge of magic, like defensive spells, to fend off the aliens.

The animals might be very confused. Some could run away in fear. For example, the deer in the forest would dash through the trees, trying to find a safe place far from the alien invaders.

One great book is 'War of the Worlds' by H.G. Wells. It's a classic that depicts a terrifying alien invasion on Earth. The aliens in this book are highly advanced and their weapons are far beyond human comprehension at first. Another is 'The Invasion of the Body Snatchers' which has a very unique concept of aliens taking over human bodies in a rather insidious way. And 'Independence Day' novelization also makes for an exciting read, with its large - scale battles against the invading aliens.
