To beat Gregar, stay on your toes and use the Slashman link navi with Megaman, because it does 80-100 damage and if you move quickly should beat him fairly easily. Remember to save before the battle because it might take 2-3 tries before you can get the hang of it, but when you do, it'll be easy to win. If you don't have Slashman link go to Green Town and help the lady giving cooking lessons. Once you beat the challenges you'll get to use Slashman as a link navi.
