Pretty much all of them. I transform out of the package (if needed) what I want to display as, 90% of the time being bot mode. I'm very much in my display piece phase of my old fart collecting 'career'. To be honest, while I love the modern engineering, there's a heavy emphasis on cost cutting with the reduction of plastic. TF once and there's already stress marks on the hinges. Over use of clear plastic that's painted versus just clear plastic panels for windows. And of course clear plastic means other pieces in the mold not needing to be clear are also affected sometimes. Not really complaining, it's just the current state of the toy industry.
Oh and of course plasticizer soft plastic parts included with the toys, such as Weirdwolf.
I love the blast effects too, but way too chicken to display any of them.
