Take a look at these ultra-fun Custom BATMAN Mighty Muggs Figures created by an Artist named David Krawczyk. He recently submitted these to the BAT-BLOG.COM with the explanation that he will be making more characters. That's great news because these examples are very cool! Here are Catwoman, The Joker ( Green Lantern Corp outfit ) and Two-Face... excellent!
Now, for the few people who don't know, "Mighty Muggs" are toys made by Hasbro and, for certain legal reasons, they will NEVER make any DC Comics' Superheroes. So, Fans of the BATMAN usually have to create their own customs. The basic reason is that Mattel has that license and Hasbro does Marvel ( They also do the Transformers, G.I.Joe, and Star Wars ).
Thanks David, great job on these!!
