Hahaha .. This thread got you curious .. I know this guy too from somewhere in Naruto but i can't remember when or what episode he was shown .. But absolutely not in the Shippuden ..

But the daughter, yeah i know her .. I'm following and watching Boruto .. She's the one who fight with Sarada and got beaten, then Sarada copied the Lightning Ball Techniques and made it as her own technique and used agains Shinki in the Chuunin Exam Finals with Boruto ..
