How to you fight and kill zant. Plz explan ?

PART 1:
Use you gale boomerang to knock him out of the air, then attack him with
your sword.

PART 2:
Put on your iron boots and block his attacks, when he gets tired and slumps
over move in and strike (take off you iron boots before you move in).

PART 3:
Zora Armor & Iron boots on, clawshot ready, wait for him to reveal himself
from behing his own head, claw him over to you and attack. (When there are
four heads watch to see which one he is under and swim towards it).

PART 4:
Monkey miniboss, roll twice into the pole he's standing on and attack him.

PART 5:
Hit his ankles with the Ball & Chain, this will make him shrink, attack him
with your sword when this happens.

FINAL PART:
Jump out of the way of his spin attack/combine harvester style move, and
attack him when he's slumps over like from part 2. After all that HC 8 is
sitting on the throne.

To fight Zant you must kill him in many ways. He has many forms and I may not remember them all. In his Diababa form I think you just use the gale boomerang against him when he is not firing at you. In his Goron mini-boss form put on the iron boots and walk towards him while he is jumping like a maniac. He will dissapear and reappear somewhere else and shoot at you. Take off the iron boots and put your shield up. When he has stopped slash him like mad. In his Morpheel form straight away put on your Zora suit and have iron boots handy. Don't get too close to the statues mouth or it will blow you wawy. When the statues mouth opens put iron boots on and put your shield up. When he has stopped firing drag him out using the clawshot. Now there are multiple statues. He is only in one of them. It is random. Do the same to beat him when you find him. In his Monkey mini-boss form just roll into the platform he is on when he shoots at you then slash him like mad. I think his last form is Blizetta where he turns HUGE. Just use the ball and chain to hit his foot and then slash him. Now you will fight him normally. He can randomly warp about the arena and launch 3 attacks at you. Slash, spin and he can fire at you aswell. The best time to get him is avoid his spin attack and he will stop dizzy. Hit him then. Do this a couple more times and you have beaten Zant.
Hope this helps.
