Preon

Preon (プレオン) is the most common type of enemy fought on Mega Man X: Command Mission. They appear in almost every area from Giga City and come in a variety of different forms, each with a unique set of attacks and abilities.

=List of Preons=

Preon Chaser
Preon Chaser (プレオンチェイサー) is the first type of the Preon series of robots in the game, and are very common.

This particular Preon has a stun gun that can temporarily Bind the target, slowing the character.

Preon Bitmaster
Preon Bitmaster (プレオンビットマスタ) is one of the first enemies encountered in the game that is able to summon other enemies.

It is suggested that one destroys the Bitmaster before going after the Bits, seeing as if the Bits are destroyed, the Bitmaster will just summon more. If many Bits are destroyed, the Bitmaster may run away. The Preon Bitmaster only acts when two Bits are present.

Bit

Bit is a small enemy summoned by Preon Bitmaster. They attack with shots.

Preon Spark
Preon Sparks (プレオンスパーク) are Thunder-based Preons, as their name implies.

Their attacks are Thunder-based and have a chance of inflicting Bind on the target.

This is the only Preon type available in the Deployment Center.

Preon Pod
Preon Pods (プレオンポッド) are ice-based Preons.

These Preons use an ice cannon that requires charging up before use. One can interrupt the charging sequence by knocking them down.

Preon Gunner
Preon Gunner (プレオンガンナー) is equipped with a machine gun capable of either inflict multiple hits or attacking the entire party. This type of Preon also has a move capable of Binding a character.

There is two Preon Gunner varieties, the one with level 31 being able to use Riot.

Preon Elite
Preon Elites (プレオンエリート) command a group of Preons and is capable of giving them orders to concentrate attacks on a single unit. The command lasts until the Elite is destroyed, and the other Preons go back to choosing their own targets.

This type is also equipped with a shield, which they can use to block attacks. Unlike other Preons with shields, they are the only ones to use Shot Attacks. That is, if you don't count Preon S Ferham's Energy Sword attack.

Preon Elites can also give orders to your units that have gone Berserk, most likely caused by the Riot attack of Preon Gunners that are always seen with it in Gaudile Labratory.

Preon Soldier
Preon Soldiers (プレオンソルジャー) are a high defense model capable of parrying a fair amount of attacks.

Though they do not do it often, they are also capable of healing themselves.

Preon Nurse
Preon Nurses (プレオンナース) are able to heal and boost the stats of their allies.

Unlike most Healer type enemies in most games, these units are better left alive, for when they are the only one remaining when it is their turn, they will surrender, heal the entire party, and on their next turn will flee the battle with a “Thanks” for letting it live. This is a convenient way to regain the health of your party for free.

Destroy it before it runs if you are trying to gather the Build LE Item since that's what they have a chance of dropping when defeated in battle. They also may drop the Injector, a Weapon for Cinnamon that oddly have the effect of Virus for a syringe.

Preon Shielder
Preon Shielder (プレオンシールダー) is another model of Preon with a energy shield.

While it has its shield up, it is weak against melee attacks and strong against shot attacks. Also, shot-based attacks will net you a counterattack. You can negate the shield by hitting it with a melee attack. If the Preon still has its shield when its next turn comes around, it will shoot it at one of your party members.

Preon Doc
Preon Doc, short for Preon Doctor (プレオンドクター), is a type that acts similar to the Preon Nurse. The Preon Docs don't surrender though. This is because, unlike the Nurses, the Docs actually do attack.

Preon Tank
Preon Tank (プレオンタンク) is a type of Preon with capable of using oil on the party.

This attack can temporarily lower the player's resistance against Fire. The Preon also happens to be weak against Fire itself.

The party can win its Oil Can for your own use, which will even reverse someone who normally absorbs Fire and make them vulnerable to it again.

Preon Pressure
Preon Pressure is similar to the Preon Pod, except this one uses a hyper gravity weapon.

This attack strikes the entire party, but almost always misses. When it does work, it seems to do about half of the target's LE in damage. Either way, the player can interrupt this shot in the same way as with the Preon Pods.

Preon S Botos
Preon S Botos uses Bit Shift, gaining helpers in the form of Bigbits. Other than this, they use Mega Fire occasionally and defend often. When their health is low, they may self-destruct to damage one enemy. They, for some reason, never use their swords. They only use Mega Fire or Bit Shift. Even if they're berserk, they only use Mega Fire.

Bigbit
Bigbit is a small enemy summoned by Preon S Botos. Their attacks cause negative status like bind and virus.

Preon S Ferham
Preon S Ferham can inflict multiple hits with their sabers, and sometimes can wear down your units' stats with moves such as Armor Pealer and Power Leak.

Unlike the other sword-and-shield Preons, they can use S-Class attacks with Energy Sword, an attack where they fire a green ball of energy from their Saber Arm. They can also use Mega Blizzard since it is considered as a Water-Attributed enemy.

It can drop the Force Metal known as Assassin Mind, which raises the user's Critical Hit ratio.

Preon S Face
Preon S Faces "charge" for one round (when they are "taunting" the player). The more damage they receive, the more damage they will inflict in the next turn they attack. Destroying them first in battle is preferable, as two or more of them with low health can cause more damage to the player.

Preon S Epsilon
Preon S Epsilon is a powerful sword-wielding Preon type who has Codebreaker, which is probably its most threatening attack.

With the Force Metals known as "DOA Block" or "DOA Protection", the chances of Codebreaker knocking you out instantly are reduced, even though chances are already low at an estimated 35% hit rate. Better safe than sorry, though.

As you might have already noticed, all of Preon S Epsilon's attacks are overdramatic in some ways, and the reason why is unknown. One popular theory is that it was made that way to give it a unique fighting style among the other Preon S and because likes to take down its foes in style while showing off its superiority over the other Preon all at the same time.

Preon Hybrid
Preon Hybrid, known as "Preon Weird" (プレオンヘンナー) in Japan, is a mix of three different Preons. It has the body of a Preon Spark, the left arm of a Preon Chaser and the right arm of a Preon Shielder. This Preon type is only fought after defeating Mach Jentra in Chapter 5, where it's produced by Duboar.
