DC Superhero Girls Action Figures - size difference?

[Shaz]

I just acquired one of the 6" DC Superhero Girls figures (Harley) second-hand. I was looking at her next to my other figure from the same line (Batgirl, bought new in 2017) when I noticed something weird: Harley is quite a bit bigger than Batgirl, both taller and stockier o.O. I'm curious: is this something other people have noticed with these figures? Are they from different batches or something? They both have the same things written on them and are copyrighted 2015.

I can't weigh in as I have no experience with this line. But, I will say that I'd give the edge to Harley!

I don't have Bat Girl, but I will check Harley against Wonder Woman and Katana. Hold on a sec.


ETA: Yup! Harley is taller then Wonder Woman, and Wonder Woman is a smidge taller then Katana. I'm unsure about the rest because these are the only 3 I have.
