the goddess imprisioned it long ago when she defeated it to keep it away.
The next hardest boss I'd say is Kolokotos.
Demise
Kill the mini boss on the Sandship
Defeat 8 bosses in a row in boss rush mode.
You have to beat the bosses.
you don't always fight Ganondorf at the end. in skyward sword i think the final boss is Ghirahim and you don't see Ganondorf in Majora's Mask
Well this is a tricky question, because skyward sword is coming out for the wii, and you can get virtual console games too. If you mean virtual console then just dodge the fireballs and hit the dragon. EASY! If you mean skyward sword, the scorpion, I think he opens hit claw to attack, then you attack him. Im not intirely sure, because the game isn't coming out until next year.
The overall boss is unknown, however Shadowscythe (Necrotic Sword of Doom), is probably closest to an overall boss.
Unfortunately, he cannot. Kirby can, however get something called Triple Star after the final boss.
You get it from groglurk the boss in bludrut4.
You get it after defeating the mini boss in the second to last dungeon, the Sandship. The mini boss is a "Skeleton Pirate", and you must return him to dismantlement by defeating him in the usual Nintendo 3-hit charm manner. As soon as he is dead, the chest containing the bow and arrow will form.
It is the same sword as the one in the main menu.
