While IT doesn't have a traditional name or human form, it's described as a powerful, malevolent force that consumes love, light, and joy. IT represents darkness, evil, and the lack of imagination.
Here's why IT is considered the antagonist:
* Opposes the protagonists: IT actively seeks to prevent Meg, Charles Wallace, and Calvin from rescuing Meg's father, Mr. Murry.
* Drives the conflict: IT's presence and actions create the challenges and obstacles the protagonists face throughout the story.
* Represents the opposite of good: IT embodies everything that the protagonists and their allies fight against.
While IT is a powerful force, it ultimately loses to the power of love, faith, and imagination, which are represented by the protagonists and their allies.
