Peni

At one point, Peni was bitten by a spider with which she formed a psychic link. The spider was housed inside her father's robot, and together, became the crime-fighting unit known an SP//dr. Peni is extremely intelligent, being at least on par with Peter Parker of Earth 1610 in terms of technical skill. She is also brave, friendly, and a generally a happy-go-lucky person.Due to being one of the youngest of the spider-people, she is also very energetic, optimistic, bubbly and peppy as they come, often making magical girl, or idol singer poses, and loves jpop, candy and comics.However, despite her upbeat nature, she is shown to be a little ruthless, tough, aggressive, smug and vain for someone that's optimistic and young.

Despite her bravery, Peni is shown to be emotionally vulnerable, as she was grief-stricken upon SP//dr's destruction and by the reminder of her father's death. Much like the other Spider-People, Peni's initial motivation to become a crime-fighter was the death of a loved one — in her case, her father's. As she shares a psychic link with the spider inside her robot, Peni can summon SP//dr at any time to fight and is able to coordinate their attacks to their advantage. Peni's Spider-Sense allows her to keep a spare set of eyes when it comes to detecting threats, and fellow-Spider-People, around her. While inside her robot, Peni has access to spiderweb-like material that the robot can release, which they use to swing through the skies and entrap enemies. Peni is quite intelligent, particularly when it comes to electronics. Peni's added strength, through the spider and robot, allows her to fight villains, particularly whilst in her robot SP//dr. Peni is also seen to be skilled and agile even without the robot. Peni speaks English and Japanese

She wears a Japanese uniform and has a green skirt, She wears a cyan backpack on her back.
