Chitauri Scepter

"You question us? You question him? He, who put the scepter in your hand, who gave you ancient knowledge and new purpose when you were cast out, defeated?"

―The Other^[src]

Loki Laufeyson wielded the Chitauri Scepter in The Avengers, gifted to him by Thanos.

History

The Avengers

"Sir, please, put down the spear!"

―Nick Fury first meeting Loki^[src]

The scepter had a long golden handle and a black fitting which held a blue gem encircled with silver blades. It allowed its owner to open rifts through dimensions with the Tesseract as a gate key, fire destructive blue energy blasts and bend the wills of others. Subjects are placed under control of the scepter by placing the scepter on their chest for a moment, at which time their eyes momentarily turn black, then change to a blue color similar to that of the Tesseract itself with no visible pupils.

Loki used the scepter to brainwash Hawkeye, Dr. Selvig and numerous S.H.I.E.L.D. agents into his followers. He could transform it at will from its long, fully-extended appearance to its smaller but equally deadly form the same way he transformed his own appearance with and without his full body armor and cape. He also disguised it as a cane when disguising himself as a human in a lavish suit. The scepter also functioned as a devastating close-range weapon, being able to violently impale and slash enemies and besting most in combat with ease. It was even strong enough to match Thor's mighty hammer Mjølnir in close-quarters combat, much the same way Odin's spear Gungnir had when Loki wielded it in his first duel against his adopted brother, Thor.

Captain America: The Winter Soldier

The Scepter was obtained by HYDRA and was being tested on by scientists under Baron Strucker's authority.

Trivia

Fans have speculated that the blue crystal or the entire staff itself is the Mind Stone from the Infinity Gauntlet.
In the mid-credits scene of Captain America: The Winter Soldier on one of the monitors in the background, the Staff can be seen being taken apart piece by piece, digitally, hinting at the possibility that the stone inside the staff is capable of being separate from the staff itself.
