My biggest collection is by far my GI Joe Classified collection. I have a little bit of everything but GI Joe has been my jam since I was old enough to say the words. I haven't even seen my entire GI Joe collection all in one place out of their storage bins because it would take up a lot of space and I'd have to put it all back away.
For 6" scale I also have most of the Indiana Jones Adventure Series line and a few Black Seires Star Wars figures, and the odd custom figure here and there, and I got some IDW TMNT figures from Loyal Subjects before that line ended (RIP). I've been slowly collecting some vintage Lord of the Rings Toybiz figures with the intention of customizing and improving them, but that's a backburned project. Also I have some MOTU New Eternia figures and a few random one or two off licensed figures from movies and shows.
Beyond that, I have some 3.75" GI Joe figures and vehicles, mostly in the 25A style, and not much in the way of O-rings, my childhood ones all broke and I think I've only found like 2 of them. I started collecting figures and vehicles Star Wars Vintage Collection after giving away all my 90s Kenner toys a few years ago, and I have some Re-Action and Playmobile Back to the Future toys (which are acutally cross compatible with a few minor modifications to the car). Lastly, I have some big Godzilla and Kong toys and some Jurassic Park dinosaurs. Not a lot but I figured they were worth mentioning.
GI Joe in particular has always stuck with me. I grew up with the cartoon and always liked the characters, and one day I found some of my old toys in a box that was enough to rekindle my interest in them. I went on eBay and figured I'd just get a few 25A figures because at the time they were cheap, but once I got my first classified figure it was RIP wallet time.
