A Crucial Item

The Scepter, occasionally referred to as Loki's Scepter, was a staff weapon that served as the original containment vessel for the Mind Stone, one of the six Infinity Stones. Gifted by Thanos, the staff was wielded by Loki to lead and command the Chitauri Invasion to Earth. After the Battle of New York, the Scepter was confiscated by HYDRA, whose scientists used it to give extraordinary powers to the twins Wanda and Pietro Maximoff. Following HYDRA's defeat, the Scepter was retrieved by the Avengers who took it to Avengers Tower where Tony Stark experimented on it to complete the Ultron Program. The Scepter was taken and dismantled by Ultron after shattering its blue gem casing, which in the process revealed the Mind Stone inside.
In 2023, the Avengers initiated a Time Heist in order to resurrect the lives Thanos had claimed. Captain America, Iron Man, Hulk and Ant-Man were sent back in time to 2012 during the Battle of New York to retrieve the Mind, Space, and Time Stones, with Captain America successfully obtaining the Scepter from HYDRA agents. Following the Battle of Earth, where Iron Man used all six stones to kill Thanos and his army at the cost of his own life, Captain America time-traveled to 2012 to return the Mind Stone, albeit without the Scepter.
