Nasty Owl

2x Tesla Coil

3x Directional Cannon

4x Missile Launchers

2x Laser Cannons

The Nasty Owl is the final Boss of Sky Force Anniversary's story, found on Stage 8 and as an impossible obstacle in the Prologue.

## Appearance

The Nasty Owl appears to be a large aircraft with a boatload of weaponry on the front, center, wings, and even in the rear. The gun ports contain multiple different weapons.

This plane is the second largest flying object in the entire series. This is only crowned by the Lewiathan from *Sky Force Reloaded*.

## Armaments

**Phase 1**

* 4x Cannon

2 gun ports on each side will pop up a standard Cannon that fires single bullets at regular intervals. Keep in mind that the gun port is not completely destroyed.

* 1x Swaying Chain Gun

A hatch at the center of the plane contains multiple weapons. But at this 1st phase, it starts as a Chain Gun. The gun, however, isn't aiming at the Player. Instead, it fires in a single wave pattern. Once it finishes firing, the gun will lowered down and the hatch will be closed. While it's taking cover, the Player is unable to attack it (unlike many other enemy turrets).

**Phase 2**

* 2x Tesla Coil

On the front between the cockpit are Tesla Coils that resemble large turbines. When in proximity, the Tesla Coil will activate and zap the Player endlessly.

* 4x Chain Gun

Using the same gun ports from the previous Phase, the Chain Guns will pop up and fire a stream of bullets at the Player.

**Phase 3**

* 1x Hexa-Radial Wall Cannon

The secondary weapon from the hatch in the center of the plane. The Cannon fires a row of bullets and each row has a total of 10 bullets in hexagon pattern.

* 4x SAM Launcher

The last weapon compartment of all 4 gun ports. This 3rd Phase has launchers that fire strong lock-on missiles.

* 2x Mega Lasers

The Mega Lasers are equipped in each side of the wings of the aircraft. The Lasers remain active for the entire fight up until this point. It can't be hit until "Phase 3.5" when all Phase 3 turrets are broken.

**Phase 4**

* 2x Hexa-Radial Stream Cannon

On the rear of the plane in each fin is a Radial Cannon that fires a stream of 10 bullets in a thin line in hexagonal pattern. The Cannons at each side fire at the same time. These parallel the Radial Cannons of this variety in the level proper.

## Combat Routine

### Prologue

The only way to finish here is to let the Plane be exploded. Regardless of the damage or survivability, the Tesla has infinite range after some time.

### Stage 8

**Phase 1**

At the start, 4 Cannons will immediately begin firing at the Plane. The Chain Gun will also engage, but only from time to time. Destroy the Chain Gun if there are unpleasant interruptions and the 2 turrets in each wings. The ports are not completely destroyed.

The Laser Cannons can catch a Player off guard due to the Nasty Owl's swaying motion, and aren't breakable until Phase 3.5. Stay away from the near-edges during the fight.

**Phase 2**

The Tesla Coils will immediately activate and begin doing heavy damage over time to the Player if they fly too close. Combined with the Chain Guns, it can put them in a tight spot. Luckily, the Tesla Coils are relatively weak, all things considered.

**Phase 3**

One of the hardest Phases in the game. Four SAM Launchers will engage, along with a never before seen weapon that shoots hexagon sheets. Better destroy that unique weapon as it will cover the arena very quickly, then take on the SAM Launchers.

Mega Bombs are extremely effective on all Phases, but especially useful on this one due to the sheer amount of stuff on screen. Note: A maxed out Mega Bomb will one shot every weapon on Normal, leading to a very easy fight.

**Phase 3.5**

The two side Mega Lasers that were gunning for the entire fight are finally vulnerable. Arguably the easiest Phase in the game, like a well deserved break.

**Phase 4**

After all front weapons are destroyed, the plane will turn tail and run. The two Radial Cannons act like the ones seen earlier in the level, shooting long, straight lines of energy bullets.

## Trivia

* The Nasty Owl can be seen being repaired of the damages caused by the Player during the Prologue. This can be seen when passing through the hangar section of Stage 8.
* When this Boss is defeated, it doesn't obliterate in explosion immediately. Instead, the credits play where the plane is descending from the skies and crashes on the ground. This leads to the canonical death of General Mantis. How he comes back to fight on higher Difficulties is not known, but it might just be for gameplay reasons.
* The Nasty Owl in the Prologue has the Laser Beams fire at the same time, but the Stage 8 version has alternating fire. It also appears much more choppy in the Prologue.
* It is odd that Tesla Coils destroy the plane from any distance in the Prologue, while Stage 8's has a limited range.
	+ Due to fighting in stormy area in the Stage 8 battle, it might be overloaded with electricity.
* The name can be found with a Steam Trading Card, or by getting the in-game Card 10.
* Interestingly, the Frying Falcon, the Stage 8 Boss of Sky Force Reloaded, shares many similarities with Nasty Owl. Both planes have the ability to fly backwards, have high levels of firepower, and more than three Phases each.
