After downloading and trying out the Batman Beyond skin in Arkham Knight I immediately loved it. I thought it was such a cool new take on my favorite series and I tried to replicate it as best I could while still sticking to how it looked in the series. The trickiest part was the symbol on the chest. It's a sticker that I glued on then repainted red.
