Who are the main characters in Portal 2 game story?

The main character is often an unnamed test subject.

The main characters are the protagonist (the player - controlled character) and GLaDOS. The protagonist is the one who has to go through all the tests, while GLaDOS is the AI that controls the facility and creates the tests.

Some of the main characters in the story include Orc warlords for the Horde side. And for the Alliance, there are important Human leaders. They are the ones leading their respective forces through the Dark Portal and engaging in battles.

The story of Portal 2 is set in the Aperture Science Enrichment Center. You play as Chell again. Wheatley, a personality core, wakes Chell up. They try to escape the facility. There are a lot of test chambers filled with puzzles involving portals. GLaDOS, the main antagonist from the first game, is also part of the story. Eventually, there are revelations about the history of Aperture Science and how everything came to be in its current state.

The portal game story typically centers around a protagonist in a strange scientific facility. The main mechanic of using portals to move around is key. The story might involve the character's attempts to escape the facility while being faced with increasingly difficult challenges. As the story progresses, the character may uncover secrets about the facility, its purpose, and the true nature of the portal technology. For example, there could be hidden rooms or messages that give clues about what's really going on. And all this is presented in a rather unique and immersive world that makes the story engaging.

I don't know for sure as I haven't read the novel. But I would expect there to be a child as one of the main characters, probably the one who discovers the portal and interacts with the puzzle dragons.

Since it's about a pedestrian, the main character is likely to be the person on foot. There might also be some kind of antagonist or helper characters. For example, if the game is set in a post - apocalyptic world, there could be raiders as antagonists or friendly survivors as helpers. But this is all speculation without more information about the game.

The main characters in the Tacoma game story might include the protagonist who is exploring the game's world. There could also be other characters that the player interacts with, like crew members or other inhabitants. These characters may have different personalities and backstories that contribute to the overall story.

In the 'nightingale game story', if it's a typical adventure - type game story, the main characters could be the nightingale, which is likely to have some unique abilities or characteristics. There could also be a protagonist, like a young adventurer who discovers the nightingale and embarks on a journey related to it. Additionally, there might be an antagonist, such as a dark wizard who wants to capture the nightingale for its powers.

I don't know the specific 'heretic game story', so I can't say for sure who the main characters are. But they could be the heretic themselves, perhaps a brave individual who stands up against the status quo.
