A fist raised in the air that may be used as a celebratory gesture: the fist pump. Can also be used to represent zero items, due to a lack of any fingers being held up.
Sometimes used as a symbol of resistance or defiance.
Raised Fist was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.

The Raised Fist emoji supports skin tone modifiers. A yellow (or other non-human) skin tone should be shown by default, unless an emoji modifier is applied.
Platforms without support for emoji modifiers display a missing symbol character (box with a cross, alien, or question mark in it) next to any modified emoji.
