Although the age grading is for 5 years and up, this is definitely not for little kids. The stories in the comics are often a lot more dark and violent than traditional superhero stories, and they're intended for adult fans who will recognize the figure. It's not designed so much for play as for collecting and display.
Each of the six figures in this line comes with a large piece that is part of the Shark King large figure. If you buy all six figures, you can create the large action figure. Once you put the Shark King pieces together, do not remove them; the figure can only be assembled once.
