Before you can fight the final boss, you must battle the bosses of the previous 4 worlds. Mercifully, they only take 5 hits each to defeat, and if you lose a life, you'll continue from the last boss you were fighting.
Bagura Head / バグラーヘッド flies around in circles and drops electrified spheres; these can be destroyed with a bomb blast.
This form requires 5 hits to defeat.

The second form will electrify it's lower half and scatter some of your items if it comes into contact with the player; during this period it is invincible. When its electricity is off, it will send a stream of slow explosions down the lanes; this is when it is vulnerable to bombs.
Requires 5 hits to defeat.
