Preon

Preons are the most common enemies fought on Mega Man X: Command Mission. They appear in almost every area and come in a variety of different forms, each with a unique set of attacks and abilities. The list goes as followed:

Preon Chaser
The first of the Preon series of robots, which are like the Joes of this game.

This particular Preon has a stun gun that can temporarily Bind you (lowers your speed).



Preon Bitmaster
One of the first enemies you will encounter which summons helpers. You can either destroy the bits as it summons them (thus causing it to waste turns summoning more), or ignore them and take out the Bitmaster first.



Preon Spark
Thunder-based Preons, as their name might make you guess. Their attacks are Thunder-based and have a chance of inflicting Bind on you.



Preon Pod
Ice-based robots which use a freeze shot if you give them time to charge up to it. Each Preon Pod opens the battle preparing its freeze shot attack. Hit it with a blow that knocks it over before its next turn to interrupt the shot (Or just destroy it outright).



Preon Gunner
This Preon attacks with a machine gun which can inflict multiple hits, or strike your entire party. Although there is nothing terribly fancy about its normal attacks, it does have a special move which has a chance of inflicting Bind on your entire party. There seem to be two of these, though the game names them the same thing. This is a more durable variation that has Riot.



Preon Elite
Elites order other Preons around, and block sometimes with their shields. It can also couple Riot with its “Order” to give your party members commands as well!



Preon Soldier
These guys don’t look it, but they have pretty good defense and seem to parry a lot of blows. They can also heal themselves, though they don’t do it very often.



Preon Nurse
These Preons heal and boost the stats of their allies. While normally you would want to focus on the healers in a particular battle and take them out first, in this case, if you leave the Nurse alone and destroy all of the other enemies on the battle field instead, the Preon Nurse will surrender in its next turn and heal your entire party. After that, defend until the Preon Nurse’s next turn, and it will leave the battle with a “Thanks.” This is a convenient way to regain the health of your party for free.



Preon Shielder
This robot uses a glowing blue shield a lot. 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
Sort of an upgraded version of the Preon Nurse. The docs don’t surrender though, sadly. This is because, unlike the nurses, the docs can actually attack.

Preon Tank
This guy has an interesting attack which temporarily lowers your resistance against Fire. The Preon also happens to be weak against Fire itself. You can win its Oil Can for your own use; amusingly, this will even reverse someone who normally absorbs Fire and make them vulnerable to it again.

Preon Pressure
Very similar to the Preon Pod except this one uses a hyper gravity weapon. This attack strikes your 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, you can interrupt this shot in the same way as with the Preon Pods.

Preon S Botos
These guys use Bit Shift, gaining helpers in the form of Bigbits. Other than this, they use Mega Fire occasionally. They also defend a lot, for some reason.

Preon S Ferham
They can inflict multiple hits with their sabers, and sometimes block hits.

Preon S Face
These guys “charge” for one round (when they are “taunting you”). The more damage you do to them, the more damage they will inflict in the next round when they attack. Of course, destroying them flat out is preferable. What you don’t want to do is get two or more of them low in health without finishing them off before their next turn.

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



Preon Hybrid
A mix of two or three different Preons. Only fought after defeating Mach Jentra.
