The Emerald demi armor is piloted by Tanas, who leads the Port Mary army. While it is likely that the armor has a fair amount of power, it had the misfortune to be too close to Dillguard during a discharge of power, and was thus was destroyed without even actually fighting the Rom armor.

Aluba is a fairly strong demi armor which mainly uses dimond folm (probably because it contains the diamond folm crystal). One of the drawbacks of the armor is that a person absorbed by the armor has only feelings of hatred, and in fact warps the mind of the pilot.

They Ruby demi armor is a very formitable opponent. While the armor's pilot, Gifa seems more like a preacher devoted to religous retoric, he also happens to be very focused, and good at combat. The armor makes use of a sort of focused lazer beam called the "rain of fire" which emits from the armors single eye. The sheer heat of it's attacks is enough to keep enemies at bay.

The royal family of Fairmount has long treasured a very powerful demi armor named Dragoon. While the family rules Parania, the armor is never seen (perhaps even a secret). The armor can be called up by a member of the family when needed. Dragoon contains the topaz folm crystal.

Gorgeous, having suffered humiliation and defeat at the hands of Maze set out to find the most powerful and terrifying demi armor known as Namuchi. The pilot controls the armor, but at the price of the armor devouring the life force of the pilot. The armor was nearly destroyed by Dilguar, to the point where it relequished it's crystal of saphire. Gorgeous managed to ressurect the armor with a new power source, using human life as the power to obtain folm. As long as there is human life to consume and use, it's power is tremendous. Namuchi also specializes in directly attacking the mind of an enemy demi armor pilot. The enemy pilot is basically demoralized to the point in which he/she no longer wishes to live, and then the pilot dies, making the opposing armor useless.

In order for a demi armor to be used, it must synchronize with a knight. Very rarely, something goes wrong, and a very powerful demi armor consumes the spirit of a knight, and the armor changes into a sort of horrid monster. Andental is such a demi armor. While Andental cannot truly be piloted, it can be controlled from a distance by a powerful folm user such as Gorgeous. Gorgeous also uses the despair and haplessness of spirits from people he has killed. While the armor looks like a skeleton, it in fact is entwined with spirits which are bound in suffering, which gives the armor it's power.

There was a time in mega burst space when the world resembled things on the earth in the 21st century. All that changed however when folm was discovered. With the development of fel (demi) armor, came many more advances. One advance came with a terrible price however. Something went wrong with a special fel armor which was developed that used all kinds of folm. The high fel armor developed a brain of its own and became known as Yumil. Yumil is basically living death, only existing to see the destruction and death of all. Yumil is far more powerful than any other fel armor, and in fact controls it's own army of fel armors (whether it created them itself or took over existing fel armors, I can't say). Yumil would have surely destroyed all life if it were not for the fel armor developed to destroy Yumil.

Pochomkin seemed to be very intent on doing away with Maze without any real confrontation, but when his plan falls apart, he resorts to his armor Calhorn. Calhorn is by no means a typical demi armor (it's not called 'mega' for nothing). The armor is gigantic with strength and power to match. Calhorn doesn't actually have arms, but instead uses two tentacle like appendages which make very effective whips.

Gorgon is an extremely powerful armor, piloted by Chic. While having enormous power, endurance, and being well armored, probably the armors greatest strength is in the intelligence of the pilot. Chic is no idiot, and knows when to withdraw and wait for a better oportunity. The real extent of it's power is hard to tell, since the main battle in which it fights is against the eraser, whom is immensly powerful as well.

Shiva is said to be the ultimate armor, which is nearly alive. Shiva was near a dimentional gate when the creator (Soshu) found it, and merged with it. The creator lost his/her body, although the spirit merged with the armor. The armor isn't really capable of much movement with it's body. Instead it depends on enoumous tenticles (and such). The armor is actually capable of absorbing an entire world, which fits in well with the creators plan of becoming a 'god'.
