OMG! They are so gorgeous and detailed! Ooooh, from what I can see they are from First4Figures. That's pretty cool. I remember the Dark Link one. Ever since they opened with OoT stuff they have done so many cool figures and they are limited, as far as I can recall so it is pretty awesome you have gotten such a nice collection over the years.
I like them all. I find pretty cool the details in Ganondorf's one. with the fancy cape. The painting job in TP Zelda's face and hair is really good.
