The Destiny of Zorro (Wii) Walkthrough Part 4

It took me a while to figure out the boss at the end, all you need to do is wait by his side and block his attacks until his green bar is completely depleted, then look around the area and you'll see you can hit two of the ropes holding the bell with your whip. Repeat the same thing again for the two other ropes, then the bell will fall on him so attack him with a special move during that time and repeat the whole process until you defeat him.
