Nightwing or Batman

In the ending of The Dark Knight Rises it seems more like John Blake becomes Batman, but it would also be cool for him to adopt as Dick Grayson's Nightwing. Bruce Wayne actually explains that Batman could be anyone so it would be more ideal for Blake to take over the role. 

Nightwing Suit: Nightwing's costume was built by Dick Grayson himself and specifically designed for his abilities. It appears to be light-sensitive, grows darker or lighter depending on lighting conditions in order to utilize Nightwing's mastery of stealth. It is fire resistant and bulletproof so that it provides Nightwing complete mobility and protection against advanced weaponry.

Mask: Nightwing's mask, containing an electronic transmitter/receiver and green night lenses, attaches via use of "spirit gum”. 

Gauntlets: Each gauntlet's 8 sections can contain a wide array of equipment, such as: spare Nightarangs, lock pick, smoke pellets, knockout gas, jump lines (both automatic and manual), first aid kit, and a mini-saw.

Boots: Like the gauntlets, his boots carry equipment vital for a night's heroics. Located here are flares, rebreather, portable computer, and other pieces of equipment (depending on his needs). All this, in only 7 compartments, per boot.

Holographic Computer: Nightwing retains his Holographic computer on his glove which grants him access to his own computer interface including data files and schematics. 

Utility Belt: Nightwing carries a modified version of his old Utility Belt which has several pockets around his waist for instant access to his several gadgets including:

Escrima Sticks: Dick Grayson carries Escrima fighting sticks in holsters on the back of his nightwing costume, which he uses for close combat. These are foot-long, lightweight cylinders that can be used for offense or defense. 

Handcuffs: Nightwing is equipped with custom handcuffs that hook and lock much faster than average, though this may be due to Nightwing's skills.

Explosive Pellets: Tiny marble like devices that can utilize various effects such as explosion, gas release and a tripping element.
