Since DC Direct will likely not make this figure in the future, I made my own.
I used a Justice League Series 2 Batman, based off of Ed Benes' work. This figure had a leaner look which fit Grayson nicely. Also the paint scheme and bat symbol were already what I needed, so this really required minimal work.
I made my own version of his belt based off of numerous artists' versions. There have been so many in so short a time, I figured my own version couldn't hurt as long as he was recognizable as Grayson.
The buckle is based off of Trevor McCarthy's work in Gates of Gotham. The belt front is inspired by Tony Daniels and the pouches in the back are based off of Guillam March. The belt is made from clear vinyl.
I made the gauntlets long because the "bat cuffs" that are so often drawn look lame to me (also longer based off of Trevor McCarthy). They were crafted from shrink tube and the wings are clear vinyl.
The hardest part was mixing the paint exactly right. I could have just painted him black and saved myself the effort, but it was fun to match the blue.
The belt's a little crooked now that I look at it. Easy enough to fix.
