Gotham continues on April 24, 2017 with ‘How the Riddler Got His Name’ @8pm on FOX.
While certainly a concern, Gotham has opted from day one to be its own thing, drawing from established Batman canon but not chaining itself to it.
To deviate from that path now would just be counterintuitive to everything the show has established up to this point.
Of course, this is a very early version of Riddler’s suit and it’s likely that the character will evolve and tweak the outfit as Gotham presumably continues onward with its recurring theme of focusing on the rise of Gotham City’s most prominent Batman villains.
