>vintage He-Man and Skeletor
I never had the vanilla pair of them as a kid, just the later variants. The exact moment Origins 100% hooked me was being able to finally put together the two halves of the sword. You read about the two halves in the Golden Books but didn't get to the thing with your toys....life is hard bros.
Anyways once I became a toy collector, I know I had to have these two vintage.
>Unicorna
Funny but sucks to stand on his own and can't pose for shit. I probably should have got the carded one...life is so hard bros.
>Magoon
I guess he's the best KO? All those lines seemed like they had a blond, boring good guy leader. But this one has a helmet!
>Battle Cat Man
Almost perfect. I think his helmet sits weird on his head and looks bad. Otherwise though this is exactly what I want from the crossovers.

Maybe its just the way my taste work, but I'd rather see crossovers work like the companies make the mashups that fit perfectly (like Battle Cat as a Thunder Cats character) but do a wider varity of IPs.
