In many cases, invaders are shown as being ruthless and having little regard for human life. They come to Earth for resources or to colonize, like in 'Independence Day'. The aliens in that story just start destroying major cities without any negotiation or mercy. However, some books also explore the idea that the invaders might have their own reasons that could be misinterpreted by humans.
Apocalyptic books in fiction often portray the end of the world through various disasters. For example, nuclear war is a common one, like in 'On the Beach' where the world is slowly dying from the aftermath of a nuclear exchange. Another way is through pandemics, as seen in 'The Andromeda Strain' where a deadly extraterrestrial virus threatens all life on Earth. They also use environmental collapse, like in 'The Drowned World' where rising sea levels and extreme heat are making the Earth uninhabitable.
Mermaid characters in fiction are frequently shown as being both enchanting and a bit of an enigma. In many stories, they possess a certain grace that comes from their aquatic nature. Their fishtails are often described in great detail, with different colors and patterns. They may be portrayed as lonely, longing for the human world like in Andersen's 'The Little Mermaid', or as powerful and dangerous like the mermaids in 'Pirates of the Caribbean'. They are also often associated with singing, as their voices are considered very alluring.
Movies also portray the behavior of aliens in different ways. Some are shown as aggressive invaders, coming to Earth to take over resources or enslave humanity. Others are more benevolent, like the E.T. in the movie 'E.T. the Extra - Terrestrial', who forms a friendship with a human child. The way they communicate is also an aspect of their portrayal. Some use telepathy, while others have strange vocalizations or use technology to communicate.
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.
Ocean fiction usually portrays the ocean in multiple ways. It can be a character in itself. For instance, in 'Moby - Dick', the ocean is an ever - present entity that the characters interact with. It's a place of mystery, hiding things unknown to man. It's also a place of opportunity for some, like in stories of pirates and treasure hunters. The ocean's moods are often described, from calm and serene to violent and stormy, which adds to the overall atmosphere of the stories.
In Indian science fiction, robots may be depicted as a means to bridge the gap between different economic classes. Since India has a large disparity between the rich and the poor, robots could be used to provide services to the underprivileged in a more affordable way. On the other hand, Western science fiction is more likely to explore the intellectual capabilities of robots, such as them becoming super - intelligent and challenging human dominance. Indian science fiction also has a tendency to show robots in a more spiritual context, like a robot seeking enlightenment, which is not a common theme in Western science fiction.
Extraterrestrials in science fiction books can differ greatly. In 'Hyperion', the Shrike is a very menacing and almost god - like alien entity. It has a very different nature compared to the more benevolent aliens in 'Contact'. In 'Childhood's End', the Overlords are highly intelligent and have a very long - term view of things. They are much more evolved than humans in many ways. And in 'A Fire Upon the Deep', there are different zones with different levels of civilizations, and the extraterrestrials in those zones vary from the simple - minded ones in the Slow Zone to the extremely powerful ones in the Transcend.
In many testosterone theft fiction stories, it is shown as a means to gain power or an advantage. The thief might be someone who is envious of the strength or virility that testosterone represents in others. So, they use underhanded methods like injecting a substance that extracts the testosterone from the victim's body. It can also be portrayed as a part of a larger, more sinister plot, such as creating a race of weakened individuals for easier control.
In fiction, world leaders can be portrayed as evil through their actions towards the environment. They may be shown as being indifferent to the destruction of nature in pursuit of industrial or economic growth. Books might also make them seem evil by showing them as corrupt, taking bribes or using public funds for personal luxury while their people suffer. This creates a negative image of the world leader in the fictional context.
Fiction books often use vivid descriptions and character actions to show complex emotions. The characters' thoughts and inner dialogues also help.
