The timelines of Earth-Prime, Earth-1, Earth-2, Earth-3, Earth-19, Earth-38, Earth-90, Earth-203, Earth-X, and Earth-TUD5 are a series of significant events listed in chronological order. The timeline is always in a constant flux when a person with access to some form of time travel goes backwards in time and changes events, creating a new timeline from that moment onward.
