You need identical characters to unlock paths. Now that you've dokkan awakened him you can either dokkan awaken four more dupes (not recommended) or reverse him to his previous form with an hourglass (much simpler). After reversing him and feeding him any dupe you might have, you can reverse him back to his TUR form for free. If you don't have a dupe, then you can only wait. I'm not sure if he's worth all those orbs, though.

Hourglasses cost 30 gems, so it's not a bad idea to try to save them as much as possible. For example, when the SSJ4 Goku banner came out I pulled him on my 2nd multi, but I didn't awaken him because I knew that I'd keep summoning on that banner for a while. A month later the banner went away and I hadn't gotten any dupes, so I awakened him. Then he was featured again on Omega Shenron's banner, and luckily I pulled a dupe. Did I reverse him right away? Nope, because I knew that I'd keep summoning for a while, and in the end I did pull two more dupes, so when the banner went away I finally reversed him and fed him the three dupes, and I ended up spending only one hourglass instead of three.
