- Peak Human Condition: Through a rigorous training regimen and strict diet, Josh achieved top physical condition with all his physical capabilities are near-superhuman.
- Peak Human Strength: Josh is exceptionally strong, he can easily overpower most thugs even enemies bigger than him. Like Batman, Josh can perform practically superhuman feats of strength such as lift a full-grown man over his head with one hand, throw them several meters, and rip metal structures barehanded in his environment to use as improvised weapon, and kick down steel doors. Josh can strike with enough force to overwhelm Killer Croc, bypassing the superhuman density of his mutated skin.
- Peak Human Speed: Josh possesses tremendous speed, he uses his astounding agility and immense acrobatic prowess to gain a superior advantage over his enemies, his fighting style is more reliant on speed rather than raw strength. He is much faster than anyone in the Bat-family.
- Peak Human Reflexes: He possesses enough skill to detect a Sniper and evade bullets at point blank range. His reflexes are much more advanced than Batman, and are near-superhuman.
- Peak Human Agility: Josh was extensively trained in acrobatics since childhood, developing an incredibly high agility even before he became Robin, from his intense training as the first Robin, his dexterity, flexibility, and balance have been trained to utmost perfection, granting him extraordinary agility greater than the finest Olympic level gymnasts and is superior to even Batman. He is one of the 3 people able to do a quadruple backflip. He can easily incorporate high level gymnastic and acrobatics maneuvers into his fighting style.
- Peak Human Durability: Josh’s muscle and bones are much tougher/denser than a normal human. His durability enabled him to suffer beatings to the face from Penguin’s thugs for a very extended period amount of time before Batman rescued him, and Nightwing’s face was barely damaged even still joking about it. He can also fall from heights that would surprise even Meta-humans.
- Peak Human Stamina: Josh's highly trained and developed body generates far less fatigue toxins than the musculature of most other humans, granting him near-superhuman stamina and lung capacity. Nightwing is trained to exert himself at peak capacity in all physical activities for hours before fatigue started to build up. Also, he can hold his breath for minutes from training with Batman.
- Peak Human Healing: Grayson’s natural healing abilities can heal broken bones, torn muscles, several gunshot & knife wounds and other severe injuries all within of several days to weeks and most lesser injuries like cuts, scrapes, and burns within hours to days.

His form of combat is a mixture of Aikido, Escrima, Stick Fighting, Kung Fu, Capoeira, Muay Thai, Ninjutsu and Boxing; though he is proficient in other styles as well. These combat skills makes him an immensely versatile fighter making up his lack of immense raw strength with unmatched agility making him as formidable as the Dark Knight.
