Large Body:
The massive heartless Large Body is one of the biggest heartless you‘ll find in the game. Its head and feet are quite small compared to its gut and arms. They appear in Wonderland, Coliseum and Monstro. It’ll use its gut to body slam you and jump into the air and cause an earthquake when it reaches the ground again. This heartless has a strong offense, but you shouldn‘t worry about that. What you need to worry about is its defense. Any attack that damages him, must be from behind. If you attack him in the front, it‘ll be useless. The Large Body card has the same effect as the monster itself, negating any attack done to you head on.

Red Nocturne:
A floating heartless that bears the color red. It appears throughout the castle and in Traverse Town and the Coliseum. These heartless consist of 1 attack, a powerful fire spell.

Powerwild:
Powerwild acts and looks suspiciously like an ape. Its body type give it an agile, strong appearance. The only place you‘ll encounter this heartless is in the coliseum. For a heartless looking so agile, it sure has a poor defense. It‘ll mainly spend its time chasing you around the field. This will include it clawing at you and sliding across the field. The Powerwild card has a pretty unique effect as well. It reverses the card values (ex. 9=1, 8=2, 7=3 etc.).

Bouncywild:
Bouncy wild looks like a chimp, and that doesn‘t stop her from acting like one as well. It shows off its agile body and teases you throughout battles. Lucky for you, Bouncywild only appears in the Coliseum. Don‘t fall for its tricks though. It‘ll leave bananas scattered throughout the field, and if you step on it you get stunned. It’ll shoot you from afar with a slingshot to annoy you more. The card it drops attracts fallen items on the ground for easy retrieval.

Air Soldier:

The Bandit card gives you the ‘Combo Finish‘ ability, allowing any card to deal the same damage as a finishing blow.

Fat Bandit:
The Fat Bandit may look similar to the Bandit heartless, but takes more after its brother Large Body. He can also be a tougher opponent than his big brother too. No worries though, you‘ll only face this heartless in Agrabah. It can jump in the air and cause an earthquake from the resulting impact. It also walks towards you while waving its arms, still doing damage. But a new ability Large Body didn‘t have is that he spits out fast and hard hitting fireballs. You must hit him from behind to deal any damage to him. Attacking him in the front is useless. The card he drops lets you do greater damage to an enemy by attacking him from behind.

Barrel Spider:
The sneakiest heartless that you‘ll face in the game. Not in battle though, beforehand. It‘ll pose as a normal barrel, but when you strike it you get a surprise.

The Search Ghost card allows you to drain your enemies health when you attack them, but the cost is that enemies drop fewer items.

Sea Neon:
Sea Neon is the generic heartless in Atlantica since Shadows do not appear in there. They look more or less like a squid that swims around. It can spin towards you with its tentacles dealing some damage or it can just tackle you. The card it drops gives each card a randomly selected value.

Screw Driver:
A screw driver is sometimes seen partnering up with an Aquatank. It call only thrive in Atlantica. It looks like its wearing a green swimsuit and wields a spear.

Aquatank:
Aquatank is a powerhouse fish type heartless. It has a glowing antenna on its head to attract foes before it strikes. It is seen partnering up with Screwdriver to do so pretty harsh damage on any opponent it faces. The antenna on its head is used to cast a powerful thundara spell over the field. It also spins towards you to deal some damage. Don‘t worry about that move though, it moves slowly and is easy to avoid.

It will also try to keep you from getting airborne as well by punching you into the ground. The Air Pirate card stops enemies from breaking your item cards.

Darkball:
Darkball‘s name is enough description for this heartless. It basically is a floating black ball. This nuisance appears in many worlds as well. And the reason why I say nuisance is the fact that its wild and unpredictable attacks makes it hard to defend. It can all of a sudden move rapidly in a circle or just fly straight across the field harming anyone in sight. The card it drops lets you hide your cards from the enemies sight.

Defender:
Defender is better at its defense and offense then Large Body and Fat Bandit. It usually roams the castle halls or Hallow Bastions.

Using magic against this is a big no-no, it‘ll just absorb it. The Wizard card forfeits summon cards to enhance magic cards.

But you won‘t find these guys in the wild, you have to use a black room card to face them. The card it drops uses a random enemy card effect.

Creeper Plant:
One of the three new heartless introduced in chain of memories. Appears in Wonderland, Halloween Town and Destiny Islands. It stays in one place constantly through the battle.
