List of enemies from Mega Man X4.

Enemy Table Guide[]

[Enemy picture]
Enemy name
Description/background information of an enemy or boss.
Health Points: Lists the amount of HP an enemy has.

X:
LVL 1 shots: 3 Damage
LV2 shots: 5 Damage
LVL 3 shots: 15 Damage
Stock Shots: 8 Damage
Plasma Shots: 16 Damage at first, then +2 Damage a hit
Nova Strike: 32 Damage every 5 frames

Zero:
1st Slash: 4 Damage
2nd Slash: 6 Damage
3rd Slash: 4 Damage every 6 frames
Jump Slash: 4 Damage every 6 frames

Special weapon damage is listed in the tables below for both characters

Note: These numbers only apply to regular enemies. Bosses will take significantly less Damage, and will often be immune to any special weapon that isn't their weakness weapon.
Attack Damage: Attack damage that the two characters take.
They start with 32 HP, and get +2 from every Heart tank.

X's Armor Upgrade reduces different attacks by different amounts (usually ~33%).
9 Damage → 6 Damage
6-8 Damage → 4 Damage
3-5 Damage → 2 Damage
1-2 Damage → 1 Damage
Weakness: Enemies will usually take x4 normal Damage from the weapon(s) listed here. Lightning Web is the exception—its multiplier depends on the enemy.
