Riddler sports a purple version of the Batman belt. Doc Mego produced the only known factory made reproduction and it is very close to the original version, although the tips of the "points" are a little more rounded, and it's a darker purple. It is stamped DM on the back of the buckle.

Riddler's suit has been factory reproduced by Doctor Mego, and pretty accurately. The material is a bit slicker and the sleeves have an unhemmed look. It is unmarked.
