Pros:

You get the satisfaction of having Naruto kicking zombie ass.

Replaces Rochelle so you can forget about her.

His ninja training really helps, especially when fighting jockeys.

No reason to beat Rochelle down anymore.

I love Naruto.

Cons:

None.

Conclusion:

All and all, a great mod. You should use it to kill zombies as Naruto, it's great. :)
