What is necron titans?

As an AI language model, I do not have personal opinions or beliefs. However, here is some information about Necron Titans:

Necron Titans are massive, robotic war machines created by the Necron Dynasty in the Warhammer 40,000 universe. They are heavily armed and armored, designed to crush their enemies and spread destruction across the battlefield.

The two main types of Necron Titans are the Tesseract Vault and the Obelisk. The Tesseract Vault is powered by powerful interdimensional energy and can manipulate time and space. The Obelisk is a defensive structure that can shoot powerful energy beams and protect nearby Necron forces.

Necron Titans are controlled by powerful Necron lords and overlords, who pilot the machines from within their armored cockpits. The machines are also supported by smaller Necron units, who swarm the battlefield and provide additional firepower.

Overall, Necron Titans are feared by many in the Warhammer 40,000 universe, and are considered some of the most dangerous war machines in existence.
