[Boy Blunder]

Hey everyone, a while back I started wondering just how often certain molds have been reused in the Hasbro iteration of the line. However, since I only got into the ML line in the last few years, I didn't have a fantastic knowledge of what's come in years past, so it wasn't easy for me to discern, since photos can't show things off the way that hands-on time can.

But I gave it a shot anyway, being as meticulous as I could with researching the figures that I didn't actually own.

So I've cobbled together a partial list. It's by no means complete, and doesn't go over a lot of the older Hasbro molds (the first one I started looking up was Bucky Cap, and that was a 2012 mold), nor does it include any I was overly unsure of. So if anyone would like to comment and contribute, please do. I'll mention you in the revised initial post.

NOTE 1: Some of these I wasn't 100% sure of, but thought I had a good idea about, so if anyone else can help clarify, please do. Those ones will be denoted with a question mark next to them.

NOTE 2: This will also include revealed upcoming releases, and will be edited as more are shown in full.

NOTE 3: I haven't included any Toy Biz molds, because it's much harder to track mold reuse across them, but if anyone would like to contribute there, feel free.

So, without further ado, the list! Molds are currently IDed by their first use (with common shorthand name in parentheses, where applicable).
