Jevil - Pretty simple once you learn his attacks and the easiest way to beat him.

Spamton NEO - Screw the hand attack.

Hammer of Justice - Tough if you already don't have a lot of experience with the green soul.

Weird Route Spamton NEO - Spamton NEO but you are alone and his attacks hit like a truck.

ERAM/Nightmare - I suck at Zelda

The Roaring Knight - They may be a fraud, but they beat my ahh every odd numbered playthrough.
