Categorized as a Cyborg Soldier Level 3 by the Syndicate, and colloquially dubbed the Masked Rider by both the Foundation and the CIA, Shin transforms into a heavily mutated, insect-like humanoid with enhanced strength and regenerative abilities. Through the intense gene therapy process he endured, the Grasshopper genes bonded to his cells give him a number of abilities which are only further enhanced through his body's mutation, such as an incredible jumping range, heightened senses, bolstered stamina, and phenomenal lower body strength allowing him to run at great strides and deliver kicks of intense force. In addition, he has limited telepathic communication with other mutants, including Onizuka and his own unborn son.

As his primary forms of offense, Kamen Rider Shin brandishes the High Vibration Nails on his fingers, and the Spine Cutters on his forearms, both of which he uses to violently disfigure and decapitate enemies. Both are highly acute and razor sharp, and when they're dull or break, Shin can quickly replace them through his advanced regeneration.
