Hi! There are actually quite a few counters to him including teams that can do double standard attacks such as the GNW treasure ninjas and more. Players invested in an event based on chance and earned them. I agree that he is strong, but he is not invincible. There are multitude of ways to counter him and you can definitely call on the community to help you in your quest to improve. You can find the strategy forum here. You can do it, there are many viable options. I recommend taking a screenshot of your ninja and giving us the opportunity to help you. Hope that helps!
