You do have to keep in mind we barely know anything about Jugo, He has a weir ability that when he goes into his anger he becames insanely strong and its basically like he is under super pain killers. He is probably one of the most characters
that hasn't shown all his abilities. Kisame was a constant character and we got a real in depth understanding of kisame's strength through his battles. The most we know about jugo - Cause of curse mark - meaning he will be a
master of it so will have immense power. Kimmimaru trusted him and his strength so much that he trusted him to keep Sasuke alive at all costs. He was practically A's B during the Summit but this what A going hard core no joke serious. A
himself even thought Jugo was dead after that but nope he just launched out the wall and then he seemed really serious. I just can't wait to see what Jugo can dish out with the new part they are at where him suigetsu Sasuke and Orochimaru
( Who wants Sasuke to be another notch in the belt in his bed ) Which mostlikely this will lead to a battle of them vs Orochimaru and we will greatly see all their strengths.
