Gigachad is a meme character based on a series of heavily modified greyscale photographs by Russian photographer Krista Sudmalis. Similar to Yes Chad, Gigachad is used to express support or praise for one’s politics or actions in some hateful memes. The Gigachad is also used in non-hateful contexts to satirize an “optimized”, or efficient and productive person.

The character often personifies a extreme perception of traditional masculinity. For example, within incel communities Gigachad can be used to represent genetic superiority and desirability. White supremacists sometimes use Gigachad as an avatar for themselves, their movement, or white men more generally.
