Is it in scale? 5 star Poison Ivy

So I see a lot of accessories and figures in other lines and I wonder, is that in scale with the other lines I collect?

So I own the Batman Nendoroid, but there’s those 5 star vinyl figures that are roughly the same shape. Are they in scale? Let’s find out.

So, kinda. If we assume Poison Ivy is shorter than Batman. It’s not perfect, but for posing or background figures the 5-star figures are fine. YMMV
