Wav seems to be "saltier than Pearl from Splatoon 2." His dialogue seems to be a version of PlotagonRocks' way of typing.
Wav is seen as Cube 7, the cube unlocked by completing Polargeist in normal mode. His name and colors nod the character he parodies.
- Wav parodies Wave, a fan-made Just Shapes & Beats character appearing in a lot of fanart.
