My Hoard of Cain
I have tried over the years getting every comic with him in it though I'm behind on new stuff. The binders on the bottom are mostly comics with him on the cover in appearance order but I ran out of space and the box holds the rest and duplicates. I pulled a few out for the pic.
Assuming I have everything marked, I have 209 individual issues not including duplicates and variants.

And then onto the figures which I don't have as much of. Including a few I customized.
My favourite story wise is probably the The Spider-man Gauntlet stuff. Art wise probably the 90s Hulk appearances or 2020 solo, but New Excalibur is what started it for me when I got the trades because I liked one of the artists on it.
