What are the Woolworths Marvel Super Discs and what do they do?

Woolworths Marvel Super Discs are a connectable 12 prong plastic ‘disc’, with a total of 42 to collect.  Each disc features an action shot of a Marvel character and also details their levels of strength - which will be used in the game play. There are seven teams of characters to collect; each group has its own colour with six different characters. Marvel Super Discs can also be used to build fun shapes and structures.
