====Alternate 2014: Thanos' Plan and Nebula's Betrayal====
In an alternate 2014, Thanos discovered that Ronan the Accuser had located the Power Stone. He prepared his daughters, Nebula and Gamora, for a mission to retrieve it. However, Thanos became suspicious of Nebula after detecting that her mind had been tampered with. His concerns grew when he found evidence of her future self's intentions to take the Power Stone for herself.

Thanos ordered Ebony Maw to run diagnostics on Nebula's memory, discovering that her mind had been merged with her future self's memories. Maw revealed that these memories were from nine years later and included information about the Avengers planning to undo Thanos' actions. Realizing that the Avengers were aiming to prevent his future self's actions, Thanos was intrigued by the possibility of his own destiny being altered.

Thanos observed his future self's interactions and the eventual destruction of the Infinity Stones, leading to his own demise at the hands of Thor. This confirmed his belief that his destiny was fulfilled. Understanding that his current actions would shape the future, Thanos decided to use this knowledge to his advantage.

He captured 2023 Nebula and used her to devise a plan involving the Pym Particles, which would allow time travel. Thanos ordered 2014 Nebula to impersonate her future self and recover the Infinity Stones from the future. Thanos also directed Ebony Maw to reverse-engineer the Pym Particles to enable his fleet to time-travel and follow the Avengers.
