Overwatch Null Sector: What You Need to Know

Overwatch Null Sector omnics are being positioned as the villains in Overwatch 2, at least according to the latest trailer released by Blizzard. These extremist omnics used violent force in pursuit of omnic rights, and they've appeared in Overwatch before. Here's what you need to know about them.
I actually think my question about Overwatch 2 is how the story explores the Omnics. Right now, they just sorta seem to be a faceless enemy, despite us having a fondness for a few of them. Will they just be treated like robots to destroy or sentient entities?

Overwatch Null Sector: What You Need to Know
Null Sector first formed seven years before the start of Overwatch's main story line. These omnics, fed up with the inhumane treatment the English government subjected them to, rose up in violent rebellion. Their rebellion began in King's Row and lasted about a month.
Twenty seven days into the King's Row Uprising, the prime minister of the United Kingdom forbade Overwatch from stepping in despite Null Sector having taken more than 100 hostages and hurt or killed thousands.
Commander Jack Morrison — before he became Soldier: 76 — authorized an illegal Overwatch mission to end the crisis, sending Tracer on her first mission as an Overwatch agent. She was accompanied by Reinhardt, Mercy and Torbjörn in what players experienced as the first Archives event.
Though new forms have appeared in Overwatch 2 materials, Null Sector omnics have been catalogued in the following types in original Overwatch:
- Bastion Siege Automaton B73-NS
- Detonator
- Eradicator
- Nulltrooper
- OR14-NS
- Slicer
In the Overwatch 2 reveal cinematic, Null Sector omnics can be seen attacking Paris. Why the group has returned remains unknown, and will likely be the focus of Overwatch 2's story — at least at first. Talon likely remains the shadowy organization behind the scenes.
