The first one appeared and attacked Giroro, after she implanted the prohibition sign of a gun for everyone to have a healthy lifestyle, this angers Giroro. Soon after all the 723's start to 'protect' everyone from harm, ending up attacking Keroro, Tamama, and Natsumi Hinata. Soon Giroro placed the prohibition sign's on all the 723's, causing them to see each other as threats. They soon started attacking each other.
She looks exactly like Natsumi, but with cybernetic features, she has gray plates for ears and her hair is more a cyborg appearance. She also has a black prohibition sign on her forehead (originally the word 'Prototype' in the manga) . Her eyes are oval and black, giving it more simplistic and cartoonish looking.
