Alien

The Aliens are the final boss in Fantasy Zone, which are released from Opa-Opa's father, O-Papa. While they are not vulnerable to anything, each Alien will take more hits then the last one to kill it. Their silk acts as a wall, meaning Opa-Opa cannot fly through it. Their patterns follow this.

Alien 1: A simple Alien that goes up and down. It is very slow, and should take only a few hits to kill it.

Alien 2: This Alien will try to trap Opa-Opa by centering the screen with it's silk.

Alien 3: Like the 2nd Alien, except it goes left and right before going up and down.

Alien 4: Like the first Alien, except it will leave large gaps, and moves a little faster.

Alien 5: Splitting the screen when it reaches Opa-Opa's height, it will then attempt to box Opa-Opa in.

Alien 6: The final Alien, it will follow Opa-Opa to no end, takes a lot of hits to kill, and moves very fast. It can also be trapped to kill itself if players are skilled enough to do this. Other options on killing this last nemesis is to use a Heavy Bomb, or use Rapid Fire on it.

Once all Aliens have been killed, Opa-Opa gets mixed emotions that his father, O-Papa was leading the Menon Forces.
