Golden Axe/Enemies

Like many arcade games of the time there are only a few enemy types (seven in this case) which are then recolored to indicate their stats. The stronger an enemy the more damage it adds to the base values of its attacks. The numbers beside attacks indicate how many life bars (or fractions of life bars) it removes.

Heninger
You cannot block their dash attack.

Longmoan
Unlike the Heninger, the Longmoan's dash attack can be stopped, but only by your own dash attack.

Amazons
Dash attacks can't be blocked.

Skeletons
Except for the downward thrust, Skeletons deal double the damage of any other enemy. Purple Skeletons are only seen in the arcade version and ../The Duel/ mode. Note that Death Bringer's Skeletons can be killed; they have 256 HP whereas Death Bringer himself has only 128 HP, meaning he usually dies first.

Bad Brothers
Attack strength: C (Green), B (Silver), A (Red) Attack speed: C (all variants) Dash attack: 8 HP (1/2 bar) All other attacks: 16 HP (1 bar)

Bad Brothers cannot ride Bizarrians. Dash attacks can be stopped.

Knights
Attack strength: A (all variants) Attack speed: B (Silver), A (Red, Gold) All attacks: 16 HP (1 bar)

Cannot run or ride Bizarrians.

Death Adder/Death Adder Jr.
Attack strength: A (all variants) Attack speed: B (all variants) Axe swing: 16 HP (1 bar) Projectile: 8 HP (1/2 bar)

Death Adder Jr. replaces Lt. Bitter as the boss of ../Stage 3/ in Beginner Mode. The only difference between them is the palette and how much health they have. Death Adder Jr. also cannot run or use the projectile attack. He's vulnerable when he throws a projectile, so hit him when he does this. The projectiles can be easily jumped over.

Death Bringer
Attack strength/speed: A HP: 128 Swing attack: 16 HP (1 bar) Explosion magic: 16 HP (1 bar) Ground magic: 8 HP (1/2 bar) Dragon magic: 40 HP (2 1/2 bars)

Death Bringer can use your own magic against you! Whenever he knocks you down he'll cast a spell, which is always the highest level spell the players have access to. Early on he'll use Gilius', later he'll use Ax Battler's, and when he's almost dead he'll use Tyris' dragon. Note that Death Bringer's Skeletons can be killed; they have 256 HP whereas Death Bringer himself has only 128 HP, meaning he usually dies first.

Thieves
The Blue Thief drops magic pots. He will also steal them during the Bonus Stage. The Green Thief drops food.

Chicken Leg
Dash attack: 4 HP (1/4 bar) Tail whip: 8 HP (1/2 bar) First seen in Altered Beast, the Chicken Leg's attack is to spin around and hit enemies with its tail. Because it has to turn to attack its attack is powerful but delayed.

Blue Dragon
Dash attack: 4 HP (1/4 bar) Fire breath: 8 HP (1/2 bar) The Blue Dragon spits fire with fairly good range. It cannot move while breathing fire so is vulnerable when using this attack. Its dash attack has no such limitations.

Red Dragon
Dash attack: 4 HP (1/4 bar) Fireball: 8 HP (1/2 bar) The Red Dragon's fireball can hit enemies across the screen (or even offscreen). Like the Blue Dragon it is unable to move while spitting fire. It also cannot spit another fireball until the previous one is gone.
