Suggested by Sonic Ururu had a pretty impressive showing in Bleach when she dealt some damage to one of the Arrancars. She may not have gotten a whole lot of screen time over the years but we know she can fight. Then you have Utakata who didn’t do a lot in the Naruto manga but the anime gave him some more screentime. In his tailed form I dare say that he would be able to keep up with Ururu and his destructive power is definitely a lot higher which certainly helps his case here. Ururu would need another ability to keep up. Utakata wins.
