Ruler of the Sky

The Sky Ruler is a Heartless Boss exclusive to Kingdom Hearts 358/2 Days. When Captain Hook and Mr. Smee dig up a treasure chest decorated with a dragon skull and buried next to a golden sword, the pirates' darkness awakens the Heartless that lays inside. The Boss then challenges Roxas while the Nobody explores Neverland. Upon its defeat, the Sky Ruler plummets into Captain Hook's ship, crushing it. As the Heartless Boss fades away into the light, the heart it held prisoner is finally released. Sky Ruler is fought on Day 301.

Strategy
The important thing to remember when facing the Sky Ruler is to not underestimate the Boss' true power. At the start of the battle, immediately Lock-On to the Heartless Boss. You must chase it around while airborne, so attack whenever possible. Be careful if you find yourself behind the Sky Ruler, as it will fire balls of energy from the cannon on its belly. As the Sky Ruler's HP diminishes, it begins to glow with a pink aura. It may emit a sudden burst of energy when you are at close range. It also drops homing energy balls with rapid succession. The Sky Ruler also causes geysers to erupt from the sea below, which damage if touched. That is why it is important to keep your distance from the Heartless until it settles down.

Occasionally, the Heartless Boss dives into the ocean. When this occurs, wait for it to resurface. Make sure you are out of its range, as the Sky Ruler will then quickly fire coins from its treasure chest - like mouth. The Boss is stationary during this time, so it is possible to deal damage with either the Fire Spell or even the Keyblade if you wish to take a risk. The process of battling this Heartless Boss then repeats itself from the beginning.

The Sky Ruler has yet another attack, an ability that makes use out of its sword - like wings. Turning its wings into claws, the Heartless Boss will proceed to slash you. It will also continue to deal impact damage as it flies by.

As always, equip as many healing items as possible before entering this battle. Make use of your Limit Break.
