If you browse goddess_of_victory:_nikke official_art, it's easy to notice that many of the character portraits use the same background motif of a thick diagonal line or backslash. It is prominent enough that fanartists occasionally/frequently imitate it, as this picture demonstrates.

Could this be considered a meme? Should we tag it? Its utility would be low, I would think.

Edit:I tagged it as faux nikke portrait.
