How are different types of aliens in fiction portrayed?

In superhero comics, characters like Wolverine have a form of immortality. His healing factor allows him to recover from almost any injury and he has lived for a long time. In dystopian fiction, immortality can be a tool of the ruling class. For example, in some stories, the rich can afford life - extending treatments while the poor cannot. In epic poetry like 'The Iliad' and 'The Odyssey', the gods are immortal and their immortality is used to show their power and influence over mortal affairs.

In fiction, ESTJ types are often portrayed as strict leaders or authority figures. For example, in many military - themed stories, they might be the no - nonsense commanders. ISTP characters can be the cool, practical problem - solvers, like the mechanic in a post - apocalyptic story who can fix anything with whatever is on hand. ENFP characters usually show up as the enthusiastic idea - generators, full of creativity and always coming up with wild new concepts for adventures or solutions to problems.

In fiction, aliens are often portrayed in various ways. Sometimes they are depicted as little green men with big heads and large eyes. For example, in some classic science - fiction movies. They are usually highly intelligent, possessing advanced technology far beyond that of humans.

Typically, they can be shown as either benevolent or malevolent. The friendly ones, like E.T. in the movie 'E.T. the Extra - Terrestrial', are cute and form an emotional bond with humans. However, in movies like 'Alien', the aliens are terrifying predators that hunt humans.

In science fiction books, aliens are often portrayed as having strange physical appearances. They might have multiple limbs, large eyes, or unusual skin colors. For example, in 'War of the Worlds', the Martians are depicted as large, tentacled creatures with a high level of intelligence and advanced technology but a cruel nature.

In children's stories, imaginary friends are often cute and friendly. They might be small, colorful creatures that talk in a high - pitched voice. For example, in some picture books, the imaginary friend is a little fairy or a talking animal that accompanies the child protagonist everywhere.

They are often portrayed as having feathers, beaks, and the ability to fly. Their physical forms might be slender and agile, similar to birds on Earth. For example, in some works, they have large wings that can be folded neatly against their bodies when not in use.

In some fantasy stories, adult breastfeeding relationships might be portrayed as a natural part of a unique species' behavior. For example, in a fictional world of magical beings, it could be a normal way of showing maternal - like care among adults. However, in more realistic stories, it's often depicted as a very controversial and taboo topic.

There are many different types of fiction, such as mystery, romance, science fiction, fantasy, and historical fiction. It's hard to give an exact number as new subgenres keep emerging.

One common type is the human - like alien. For example, in 'Star Trek', Vulcans are human - like in appearance but with distinct cultural and physical differences like their pointed ears and logical thinking. Another type is the insect - like aliens, such as the Arachnids in 'Starship Troopers'. They are often depicted as having multiple limbs and a hive - mind mentality. There are also the blob - like or amorphous aliens which can change their shape, like the Thing in the movie 'The Thing' which can mimic other organisms perfectly.
