Fantasy Zone/Round 8 Salfar

You've made it to the final level, Salfar, the star where an evil spirit was born. The seven bosses that you previously defeated will reappear here, one after the other. Before you start, you get one last chance to visit the shop and stock up on equipment. Choose wisely since you won't get another opportunity. There are two schools of thought when it comes to shopping. One is to stock up on as many Heavy Bombs as you can afford and use them against the bosses who are particularly vulnerable to it. The other is to select nothing other than Twin Shots and Twin Bombs since that is all you can ultimately rely upon by the end of the stage. The bosses will appear and attack Opa-Opa much more quickly than they did in the past, so you must be prepared to fight once the previous boss is defeated. Note that since the shop will no longer appear, defeated bosses do not drop coins.

Final Boss
The intro is you will see Opapa's color is gray with the 6 aliens. (sometimes, it maybe a flagship of enemy reinforcements.)  six aliens are sequentially released from the final boss. They each move in a particular pattern, and they leave a blue trail behind them wherever they go that remains on the screen until they are defeated. Opa-Opa will be killed if he touches either the alien or the blue line. Each alien gets progressively faster than the last. They will be destroyed if you hit them with five twin shots. The trick to beating them is to understand the pattern of their movements.

Once the last alien is defeated, the final boss, Opapa, will become colorful again, tears will drop on Opapa
