I love me some Bossk, because Trandoshans get allllllll da ladies. Jockin' the Wookiees and slappin' the ho's is livin' Trandoshan style.
I loved Bossk as a kid, and I don't really know why because the aliens weren't always my favorite characters. He and Snaggletooth (blue) both had the cool grin thing going on though for some reason. I liked that. I also had a love of all things Godzilla, and I used Bossk as like Godzilla's human-communicator. Weird? Yes. I was a strange kid who morphed into an even more strange adult I guess.
The modern versions of Bossk have all been pretty good... I even liked his Saga resculpt, which was a decent upgrade over the POTF2 figure. NOthing compares to the Vintage sculpt of the character though, which features a lot of depth, realism, and detail. The paint, the open mouth... There could probably be improvements, or added features, but they'd be minor.
There are 3 characters in the SW world that I have to have definitive versions of at some point, and which I try to do a little character-focused collecting and buy any goofy thing that has that character's likeness. Bossk is my main one though, and so I have lots of weird Bossk stuff around.
He'll always have a proud place in front of the other Bounty Hunters too, on my shelves. He could beat up on any of them I'm sure.
BTW, a cool mag that used to come out back in the day gave a deck-by-deck breakdown of Bossk's ship, The Hound's Tooth. It's maybe the coolest diagram of a SW ship ever.

From Wookiee skin rugs to their stuffed heads mounted in his living area... Bossk is just a lizard-man badass.
