Well if your early in the game (Which I will assume you are), bring potions, power/mega juice if you can, sonic bombs, and traps and trang bombs if possible. Try to bring dual swords with good green sharpness, and either water or dragon element. You really want armor the gives earplugs, that way his roar doesn't effect you. I think some good early game armor that gives earplugs in Hornetaur, but it might be hard to get.
