Wars (Lore)

According to the lore, there are six major wars that have occurred between the tanks and other entities. The first and second wars are the only documented ones, while the 6th is the current war, which is stuck in a time loop.

Overview
Wars tend to revolve around friction between the polygons and the tanks or the bosses and the tanks. The tanks lost the first war, but won the second. However, the second war caused AIs to evolve and clone themselves. The third, fourth, and fifth wars are undocumented, though there is much speculation surrounding them.

Some wars caused the mythical First Tanks to leave. Others caused massive upheaval in the hierarchy of the arena.

First Major War
The First Major War (1MW), fought between the simple polygons and the tanks, was hard-fought on both sides. The polygons, however, won out, and the tanks were defeated. The war caused the tanks to be unable to evolve like polygons do, instead choosing their own path. The Tank A and Implosionist projects were born from the aftermath of this war. All the tanks in Diep.io before Necromancer was added were present during this war. The most major force of tanks was a brown team.

Second Major War
Factional disputes over the Tank A project, which was intended to clone tanks, caused the Second Major War (2MW). The polygons joined in the fray, but this time were beat back. The Tank A project, however, backfired, causing the cloned mutants to break from the rest of the tanks and forge their own destiny and unique paths. T The Comet joins polygons.

Third Major War
The Oxyrrhexis was created during this war. Crashers were made by the Hemispheres to protect polygons. Mladic was the leader of this war and led the polygons to victory. Most tanks were also created in this war.

Fourth Major War
The 6th war, despite being ongoing, was not the most lethal war. The 4th one was.

The 4th war was quick, and happened due to polygon bosses becoming so deadly and advanced that their methods of killing actually became inhumane. In and attempt to fight back, the tanks stole technology from the Hemispheres to forge the AWP-39. The project went wrong and the AWP-39 turned against them and began to commit genocide. Eventually, due to fighting against a common enemy, tanks and polygons signed an agreement called "Sheba", which wanted everlasting peace, until the Fifth war that is.

Mladic was also the leader of this war and temporarily led the polygons to victory.

Fifth Major War
Little is known about this war. The only thing that is known is that it was the shortest war. Mladic disappeared at the beginning of this war.

Sixth Major War
This war is the current one, and its stuck in an infinite time loop. The Hemispheres (tanks and polygons), bound by time, are unable to solve the issue before the time loops again, causing them to forget everything and have to restart. This war is fought between the tanks and the shapes. The bosses help the shapes in their war but are always defeated, even if they massacre the armies of tanks.

The Hemispheres fight against the AI, even though the AI are technically on the side of tanks. However, tanks capitalize on the death of AI by stealing their score and killing them. This war is the only one to involve multiple different arenas and battlefields.

This time loop stopped some projects of the tanks.
