3rd raikage neg difficulty, this is true because of the 3rds resilience and "iron" skin, he also has lightning able to paralyse any ninja, he has black lightning capable of injuring edo gin and kin brother in kyuubi chakra form.....and finally what makes a great distance in power, stamina, power and speed.. Able to last 3 days in battle, move at lightning speed....and powerful enough to stale-mate with the 2nd strongest bijuu= hachibi
