Here is my custom Batman with armor and magnetic Batarangs, I opted to leave him without a cape since with all the armor I didn't see it as being nesasary, he has 2 Batarangs that can connect to the back of his belt ( holds both ) there is a metal strip on his belt and each Batarang has a small magnet attached.
Hope you like this and have a good one :)
