The original toyline really doesn't get as much praise as it deserves. Everyone remembers and holds it dearly, but the sculpting, paint, and diversity of the line holds up and is still impressive. I'd argue that it's in the top 5 toylines of all time, and I'm sure most other fans would as well.
What's your favorite figure?
I'm gonna say Tokka. It's not most peoples first choice, but hear me out- Tokka is awesome. The squat, chunky sculpt is both aesthetically pleasing and adds to the play value of the figure. The paint work on Tokka is pretty well done, and I can see hints of a paint wash years before that would become a commonly used practice in the toy industry. His design? Top tier, it even beats out Slash's original design for me.
Tokka is just a satisfying figure to own.
