4. Tesseract
Who wielded the Tesseract? Odin, Red Skull, Loki, Mar-Vell
What kind of object is it? Similar to the Eye of Agamotto, the Tesseract uses an Infinity Stone as a source of its power. The Space Stone is located in the blue cube that was utilized by Loki in the first Avengers film.
Originally, the Tesseract was long in the possession of Asgard, but in World War II, HYDRA seized the object, thus enhancing their arsenal. The Tesseract was used as an energy source. Later, S.H.I.E.L.D obtained the relic, but Loki took the Tesseract in the first Avengers film.
Loki then used the Tesseract to create a portal to unleash the Chitauri army on Earth. As an energy source, the Tesseract was also responsible for granting Carol Danvers her powers and her transformation into Captain Marvel (Source: Marvel Cinematic Universe Wiki).
