This is extra work for the 50 Indie Games Characters Icon which is about Undertale Duo/Trio stuff (EX: Bad Time Trio, Murder Time Trio) But instead of Undertale Alternate Universe, It's instead crossovers other Indie Games. Yet there are also projects created by other creators in the picture (Indie Cross, Interloper)
