Hard,hard as hell.If devil was in Metroid he will be Phantoon.It's incredible hard to defeat him without damage.This boss has many pattern of same attacks.
Main rule is use pseudo screw attack this help evade many of his attack.
This battle is about luck,but it's seems what my luck is very bad because i lost about 300 times against this bastard.
