No. Robin does turn into Nightwing, but not because he is bad. Nightwing is still an ally of Batman.
Nightwing
He changes his name to Nightwing.
No and the first robin was called nightwing
There is not supposed to be lightsaber blades. There supposed to be some sort of neon sticks. In the comic when the first robin leaves batman he becomes nightwing and uses those sticks as weopons.
