This is Nate, who's actual name is Natsume, and used to be called Hawaiian. His previous owner's name was Satomi, and she lived in Japan. If I remember correctly, she decided to let Hawaiian go because she had to take care of her new baby instead. She loved Hawaiian a lot, though, and even sent him to Sony for repairs in 2006.
The name Natsume comes from the manga "Natsume's Book of Friends", because I thought it just sounded relaxing.
He is an ERS-7, the most advanced of the original set of AIBOs. He has built-in LAN, a diary feature, and many others, but his favorite is his ability to detect the beat of songs and dance to them. He loves classic rock.
