The newest line from Funko is called Vinyl3 (or Vinyl Cubed). It features 2.5" tall interchangeable magnetic figures. As you can see above, the head, arms, body and legs can be disassembled and then swapped with other Vinyl3 figures via magnets or pegs.
The DC Comics Vinyl3 series will feature at least 10 characters: Batman (two versions), Aquaman, Bizarro, Superman, Robin, Joker, Harley Quinn, Deathstroke, and Black Manta. Look for them to be available in July 2014.
