Itsuki is a young green Yoshi with purple crests on the back of his head and the tip of his tail. His clothes are generally a darker red, and he wear gray-colored gloves. Itsuki comes from a village on Marshgreen Island and was the first person to meet Feather after his strange sudden appearance in a nearby jungle. He has a fun personality, but can be snarky or very sarcastic when he wants to. He loves exploration and finding new things, places, and people to talk to.
In terms of fighting, he has his gloves, which produce an electric transforming spark thanks to nanobots that were infused in the gloves by a professor who goes by the name of Nuhthrin Thomas, or Nuht T. for short. He can use the electricity to shock his opponents and send their body and mind into disarray as they are transformed. Without his gloves, Itsuki cannot fight, as he does not possess very much fighting skill nor is he very strong.
