Strategy
As a large Heartless, Darkside can only be defeated by hitting his hands and head. He, however, is not very difficult and the only danger is his HP attack at low levels. His hands are of course the easiest target, while attacking his head deals more damage and increases chances of dealing a Critical Hit. Use dodge roll or other dodging moves to avoid when he slams the Dark sphere and use the opportunity to attack his head. His HP attack, Shadow Storm, can be deflected, though you should only do it if needed to avoid being overwhelmed by the amount of hits.

Strategy, Location, Etc.
Ruler of the Sky is located in a unique violet treasure chest that blocks the way between you and the end of the level. Once you open the chest, this annoyance pops out. As he rules the sky, he is always airborne, so be sure to have abilities such as Glide and High Jump equipped, as these will be a vital asset.

The trick to defeating this pest is to remember its two modes: Flight Mode and Berserk Mode. When in Flight Mode, chase after it while dodging its attacks, and destroy sections of its tail. Each section is destroyed after dealing a total of five attacks on them, whether they be Brave or HP. Hitting the tail with an HP attack will NOT deal HP damage to the Heartless itself. After a section is destroyed, it will go into Berserk Mode, where it executes different attacks instead. While it's in Berserk Mode, however, you are able to directly attack him, though it won't be quite as effective as it would against normal Heartless. After destroying all three sections of his tail, he goes into a Vicious Mode, causing him to attack much more frequently, with a combination of the attacks he uses in Flight and Berserk Mode. He'll also expose his core while in Vicious Mode, allowing for you to deal more effective hits against him, thus making him easier to kill.

Strategy
The Leechgrave is a giant, immobile Heartless with four Tentaclaws surrounding it; due to the fact that it is planted in the ground, the Leechgrave only has Ground-based attacks. Attacking the Leechgrave directly will result in a nasty counterattack. Instead, attack the Tentaclaws, defeat them, and then go after the Leechgrave, which will be stunned for a while. Each Tentaclaw has around 2000 HP, while the Leechgrave has 4500 HP. Both the Leechgrave and the Tentaclaws may attack, making for a somewhat annoying fight. However, it won't do anything while it is stunned; sieze this opportunity and go all-out!

Strategy
While encountered more than once, the Behemoth is tough enough to count as a boss. The Behemoth can only be hurt by hitting its horn on its head. Crawling up his back is the only way to hit him. The Behemoth is slow but hits hard, so magic styled characters will have difficulty. Hitting the horn enough will cause it to fall over, which also adds a Critical Chance increase. However, it will immediately counter attack after so retreat.

Strategy
As per the request of Xelias, here's the Sephiroth of all Heartless: the Dustflier! Okay, so the Dustflier is an extremely powerful Wyvern-type Heartless. All of his attacks have a chance to inflict status ailments. The best way to take him out is to ensure that you are a high level and have a good Gears equipped. When fighting him, make sure that you have abilities such as High Jump and glide. If you don't, you're screwed to infinity and beyond. In the battle, make sure to dodge as many of his attacks as you can, and then strike his wings and tail until you get and opening. Then, strike the head, which will allow you to attack the weak point for massive damage. Oh, and thre's a constant swarm of Shadows along the ground; it's best to ignore them.

Kurt Zisa
Kurt Zisa is a powerful Heartless with a peculiar and somewhat complex battle strategy. It opens every battle with its “Silence” HP Attack, which robs the opponent of their ability to use HP Attacks until they inflict a break on Kurt Zisa. The Heartless’ Brave points return remarkably fast after using an HP Attack, making this difficult. Kurt Zisa takes a great deal more time to recover from a Brave Break than any other Heartless, but is completely invulnerable to Elemental attacks during this time to compensate. Only when suffering from a Brave Break will Kurt Zisa use its Brave Attacks, in an effort to regain its Brave points faster. It is immune to all status effects and resistant to Fire, Ice, and Wind-based damage. It also has a slight weakness to Thunder damage.

AntiSora
The AntiSora is a swift, powerful, Pureblood Heartless. It shares the Shadows' and Neoshadows' ability to turn itself into a flat shadow, rendering itself invulnerable. It can deal heavy damage by leaping up underneath the player and striking with its facsimile Keyblade. Its most notable ability is the power to create weaker (at least in terms of HP) copies of itself to distract and attack the player. Like all Pureblood Heartless, it is profoundly weak to Light damage, but, unlike other Purebloods, is can actually absorb Dark damage.

Orcus
The Orcus is a powerful Pureblood Heartless that is nearly identical to Invisibles. At higher levels, Invisibles have greater HP than the Orcus, but otherwise the Orcus has greater defensive and offensive strength. It is more powerful and faster than Invisibles, though it lacks the "strength in numbers" Invisibles occasionally have, as it always appears alone.

Veil Lizard
The Veil Lizard is a moderately powerful Heartless with the unique ability to turn invisible, rendering it incapable of being targeted and immune to Brave attacks. This skill is its largest asset. Its tongue attack is also surprisingly fast and can easily catch opponents off guard, but its other attacks are easily avoidable. It has moderate defense, and is Immune to three of the four status effects.

Volcanic Lord
The Volcanic lord is a fairly powerful Heartless that always appears flanked by the Blizzard Lord. While it only has one HP attack and two Brave attacks, this sole HP attack has a very wide range, and all three have the potential to Ignite the enemy. The Volcanic Lord absorbs Fire damage and is immune to Igniting and Air-Tossing.

Blizzard Lord
The Blizzard Lord is a fairly powerful Heartless that always appears flanked by the Volcanic Lord. Like the Volcanic Lord, it only has three attacks, but it is slightly less dangerous than its fiery counterpart due to the fact that its sole HP attack has a comparatively short range. All three of these attacks inflict Ice damage and can Freeze the enemy. The Blizzard Lord absorbs Ice damage and is immune to Freezing and Air-Tossing.
