You are Nikki one of nightwing and batgirl older daughter

Nightwing is a futuristic vigilante alias of Dick Grayson, who was once Robin in Teen Titans Go!. Occasionally, the Titans will drop by the future and pay him a visit. this alternate version of the hero was more mature and calm, unlike his younger self. He married Batgirl and had three kids Nikki Jake and Mari with her. He and his family lived in the Titans Tower on account of the other Titans moving out. Even though Cyborg and Beast Boy thought this future was horrible, Nightwing was actually very happy with his life and loves his family very much. Nightwing wears a black skinsuit costume with blue gloves, a blue belt, big black boots, a face mask and a blue Nightwing icon over his costume. Physical Appearance

Along with the new identity comes a new appearance. Nightwing is clothed in a dark blue kevlar suit. He still retains metal tipped boots, although these new ones have more traction cleats. A gray utility belt wraps around his waste, and blue pads adorn his forearms. Nightwing's face is roughly the same, but his hair is now fashioned into a mullet with two spikes on top. His voice is deeper. His "R" symbol is replaced with a light blue bird (although sometimes red...), coinciding with his new identity.
