The Time War is a conflict that expands throughout space and time. Most beings are unaware of the conflict or when the war took or takes place. Ben 10,000 further in the future takes part in the war. During the war, the Chronosapiens had gone rogue and temporal beasts on an cross-dimensional rampage, causing the time war to escalate. Ben 10,000 mentions a being known as Maltruent.
Ben 10,000 travelled through space-time looking for Professor Paradox asking the present Ben for possible directions. Professor Paradox in some point in time will enter into the time war. It is unknown how the war is turning out.
The effects of the time war forced Professor Paradox to take a more active role in temporal affairs and he called it open warfare on the space-time continuum. With the time war ongoing, he had to camouflage his Chrononavigator for safekeeping.
- The Time War is a reference to the TV show Doctor Who where the Time Lords faced the Daleks and the supposed destruction of Gallifrey. It is known as the Last Great Time War.
