From what players from other versions said before, 4-star Nine-Tail Chakra Naruto is OP in the other versions of this game. His 3-star version just basically has less stats and his skills are weaker. However, we won't know how strong he is until someone gets him and tries him out. He could definitely be brutal for Ranked Battle.

The more affordable option is Sage Jiraiya, who is great all the way around with the points Narbsy made. I believe his standard also goes through dodges like Hinata or Neji, but I'm not 100% certain.

Haha 2-star alone in the beginning got me to 1600 points in arena. I just can't justify the cost so wouldn't really recommend him unless you plan to 4-star him later, which would cost even more...
