All paths lead to 2 sources:
>Spiderverse
>Arcsys conference about making their 3D games looking 2D (Xrd and DBFZ specifically)
Literally just these 2. I remember when YouTube was filled with "GUILTY GEAR CHOP AND SLOP (Formerly animated)" videos and then Spiderverse sent it into overdrive due to being a massive hit.

Thankfully it finally seems to die out now. Even the new arcsys game is actually splined despite the marvel budget.
