One important quality is adaptability. Sci - fi stories can range from post - apocalyptic settings to intergalactic adventures. Actresses like Natalie Portman in 'Thor' had to adapt to a very different and fantastical world. They also need to have a certain charm or charisma, because they are often representing the human element in these otherworldly stories, whether it's in a love story within a sci - fi context or just being a relatable character among all the strange things happening.
They often possess great physicality. For example, in action - packed sci - fi movies, actresses need to be able to perform stunts or fight scenes. Sigourney Weaver in 'Alien' had to do a lot of physically demanding work. Another quality is the ability to portray strong - willed characters. Since sci - fi often involves complex and dangerous situations, like in 'The Hunger Games' where Jennifer Lawrence played Katniss, the character has to be strong - minded to survive.
Actresses in science fiction usually have a good sense of wonder. They need to convey the amazement and curiosity that comes with exploring new worlds or technologies. Take for instance, Keira Knightley in 'Never Let Me Go'. She had to show a sense of discovery and acceptance of the strange world they were in. Also, they should be able to handle complex scientific concepts, even if it's just in terms of making it seem believable to the audience.
Courage is a common quality. For example, Katniss Everdeen in 'The Hunger Games' showed great courage when she volunteered to take her sister's place in the deadly games and then fought against the Capitol.
Most famous fictional heroes are intelligent. Sherlock Holmes is a prime example with his amazing ability to analyze evidence. They often show perseverance too. Katniss in 'The Hunger Games' keeps fighting against the Capitol through all the difficulties. Another quality is leadership. Aragorn led the forces against Sauron in 'The Lord of the Rings'.
Wisdom. For example, like Dumbledore in Harry Potter. He has vast knowledge about magic, history, and people, which he uses to guide Harry.
Often, they are brave. Like Beowulf in the epic poem, he fearlessly battles monsters. They can also be intelligent. For example, Hermione Granger uses her vast knowledge to solve problems in the 'Harry Potter' series. Another common quality is determination. Odysseus in 'The Odyssey' is determined to get back home no matter what obstacles he faces.
One important quality is a deep understanding of the science fiction genre. They need to know the tropes, the history, and the potential future directions of the genre.
One important quality is courage. In science fiction novels, agents often face extremely dangerous and unknown threats. Take the Doctor from 'Doctor Who' for example. He constantly travels through time and space, facing all kinds of alien threats without hesitation. They also have a sense of loyalty, either to their organization or to a greater cause. In 'Star Trek', the agents of Starfleet are loyal to the ideals of the Federation. And of course, they are resourceful. Agents in 'Dune' have to be resourceful in a harsh desert environment filled with political intrigue and advanced technology.
They should have a deep understanding of science. This allows them to fact - check scientific concepts in the stories and ensure they are presented plausibly. For example, if a story involves time travel, the editor should be able to assess whether the scientific explanations given are at least somewhat reasonable.
Fictional war characters often possess resourcefulness. Take Katniss Everdeen from 'The Hunger Games' for instance. She uses her skills with a bow and her wits to survive in the dangerous arena which is like a war zone. They also tend to have a strong will. Paul Bäumer from 'All Quiet on the Western Front' has a strong will to endure the horrors of war. Additionally, loyalty is seen in many, like Holden Caulfield's loyalty to his own sense of self in the psychological 'war' in 'The Catcher in the Rye'.
The best men in fiction often possess courage. For example, Beowulf in the epic poem was fearless in the face of terrifying monsters. They also have integrity, like Ishmael in 'Moby - Dick' who sticks to his beliefs. And many of them are intelligent, such as Doctor Strange in the Marvel comics. His vast knowledge of the mystic arts helps him face numerous threats.
The greatest fictional leaders often possess courage. Like Aragorn, he wasn't afraid to face the powerful Sauron. They also have wisdom. Dumbledore's wisdom guided Harry Potter and Hogwarts. And charisma, which Captain Picard had in abundance, making his crew follow him willingly.
