The Stone of Mind, originally contained in
the Scepter of Loki, and later on the forehead
of the Vision - the Stone of Infinity, which
controls one of the aspects of being - the
aspect of Mind. The stone gives the user the
ability to increase intelligence and endow
other creatures with intelligence. The user
of the Mind Stone can manipulate the minds
of other beings. The stone is also capable
of projecting energy blasts and contains
artificial intelligence that can make androids
or robotic beings sentient.
The Scepter containing the Mind Stone was found
by Thanos and given to Loki to carry out an
invasion of Earth and obtain the Tesseract,
however the Scepter was lost by Loki...
