Neo, (born Thomas A. Anderson) the protagonist of The Matrix franchise, is a redpill rescued by Morpheus and the crew of the Nebuchadnezzar.
Trinity is a computer programmer and a hacker who has escaped from the Matrix, a sophisticated computer program in which most of the human race is imprisoned as virtual slaves. Morpheus is a Zion operative who serves in the city’s defense force against attack from the Machines. His hovercraft, the Nebuchadnezzar, has far less armament than its sister craft. Cypher (born Reagan) was a redpill assigned to the Zion hovercraft Nebuchadnezzar under the command of Morpheus. He was also the one who betrayed the crew of the Nebuchadnezzar to aid Agent Smith.
