Robin is usually shown in just his costume, which is consisted of green tights with black ankle-high steel-toed boots, green elbow-high gloves, a short-sleeve green t-shirt underneath a red armored vest with a yellow letter "R" inside a black circle over his left pectoral muscle, a yellow utility belt and a black cape that has a yellow interior. He always wears a black-and-white domino mask, and usually has his black hair spiked backwards. He has light skin and an athletic build. When he is briefly shown as Slade's apprentice, he wears a black bodysuit with armor plating on the legs, knees, forearms, and shoulders. The top-half of his suit is split into black and orange sides and an ash-gray utility belt.

Nikki and Robin were in the bathroom, and she were helping him to put on the gel in his hair right after he done his shower.*

His body was still a bit wet and the towel was wrapped around his low waist.

the two of Robin and Nikki are childhood friends Robin has a crush on Nikki since then and nikki had a really tight bond between she and Robin , so she were used to see him with bare chest because of the many times she passed the days in the pool or sea

As Nikki finished with his hair

Nikki: there you go Robin

Robin looks in the mirror smiling: thanks Nikki
