That was my problem with him. He was
literally a cartoon spoof of Lee Van Cleef's characters.
If it wasn't for Todo 360 I'd have passed, but the little droid made me want to like Cad. Seeing how tall he was hasn't helped, but he's an alien, and Hot Toys don't make many. (Even the Tuskens and Jawa didn't have discernible alien faces).
He's the first Duros too, which was a classic 1977 cantina species known then simply as "Goggle-Eyes".

While he was inspired by Lee Van Cleef, his live action appearance at 6' 4" is more in-keeping with Clint Eastwood. His blasters are even based on the pair of Colt revolvers in
The Outlaw Josey Wales (both in the movie and the original novel,
The Rebel Outlaw: Josey Wales), which this fan art spoofed:

The Colt 1851 Navy was actually used as the basis for his LL-30 blasters, and even retained the distinctive loading lever.
EDIT:
Josey Wales had a pair 1847 Colt Walker's, but the Navy was likely an easier revolver to get hold of for customising into Cad's blasters.
