Still waiting for KB to do something. For a Jink he should be in the front line instead of hiding behind the alliance
Unlike some of the others in the group, a lot of his attacks are based more on close contact fights. If he tried to take a swing at obito, the odds are pretty good that obito would easily wipe the floor with him. The only way to defeat him now is with high powered energy attacks which means all he has to offer is a bijuu ball once and a while. Not exactly a great offense option hence why he is pretty much side lined for much of this fight.
