The final fight in the game is against Spacetime Emperor Salamander himself. He can take three different forms. The forms are described below. The solution to defeating the final boss is an unusual one. It has been described in a spoiler window in case you want to figure it out for yourself.
Last boss forms
Form A
Form B
Form C
The initial and most common form of Salamander is as a large two headed dragon that sends lightning bolts forth. He doesn't fly too quickly, but he's faster than you are, and he tends to home in on your location, which can make avoiding him difficult. He flies to the left and to the right, so if you can get behind him, you're usually safe unless he stalls in mid-air and decides to turn around. The lightning bolts can be nullified by your boomerangs.
Occasionally, Salamander will break apart into three smaller dragons. These dragons don't fire lightning bolts, and they're not as big, so they are easier to avoid. In fact, you can defeat them by hitting them with two boomerangs for 2000 points each. If you defeat all three, or after a set amount of time has passed, the main larger form will return to the screen.
The last form is the most dangerous of all. He becomes enraged and moves directly to your location, pushing you down to the bottom of the screen as it touches you. This form is the most difficult of all to avoid. If you can, try to be at the top of the screen when he engages this mode, and drop to the bottom. It will take the dragon time to catch up to you, and may return to normal before it does.
How to defeat the boss
In order to defeat Salamander, all you must do is gather the five swords that you have collected from the bosses and situate them into the correct locations around the palace. The map to the left will show you where each one needs to go. Simply walk up to one sword at a time, and walk to the place where it must be placed. The sword will immediately appear when you reach the right location. The black sword must be saved for last. Unless the other four swords are placed in their proper location, you will not be able to set the black sword down. As soon as all five swords have been placed in the correct locations, Salamander will be defeated. This is why, even though you may opt to fight the him when your game is over, you will never actually be able to defeat him unless all five of the swords have been collected.
