BM Naruto managed to fight with Madara toe to toe,Who basically almost Slaughtered the GoKage(Five Kages) with ease. Nagato,when using bodies,and in an UNHEALTHY form,Managed to kill Kakashi,Fodderised SAGE mode Naruto,Destroyed the entire village(Which no one in the manga except Rikudou Sennin and Edo Madara can acheive)And managed a CHIBAKU TENSEI(Not as powerful as RS's,but still powerful).Kushina was known as 'The Red Death',indicating she was powerful as well.Mito,By Kushina ,was told to have a mode similar to KCM,Indicating she was powerful as well.Though Karin's weak,she a healing type,and also a sensing type.I chose Uzumaki's by the logic I've given above.
