I looked through some Psychic types through out the gen and realized that a handful shared the "space" theme so I decided to go with a pest from outer space idea. Basically put, it's a bug type Pokemon like other psychic types with the space theme that's origin is unknown and is thought to be from outer space. It's also based off the idea that the species are pests that travels in swarms, but no one seems to be able to catch them in their act because of their psychic powers;
they raid crops and leave a certain pattern behind, or
raid live stocks to feed on fresh meat. The psychic powers it has is the reason why it has abilities and moves that seems like the bugs are using some sort of alien technology.
The shape of its arms was probably the most important part of this design imo. I designed it to look like those
ray guns from old space movies.
-The silver part is hardened armor and the most fortified part of its armor meant for ripping through steel walls like some sort of space monster; I'm going to bullshit myself here and say I added this part mostly to give it the ability to learn Megahorn (if Escavalier can ram into things with its lance and count it as Megahorn, I guessed this can work too). The spikes protruding from the under side is used for climbing up or clinging on to surfaces it can stab into.
-The crystal like part is its source of its psychic powers. It can communicate to others by sending signals from it to the antennas. It is also used to produce different assortments of specially based beams/moves too. It is also used to shoot out psychic waves that cancels out its presence to living things nearby through mental manipulation, so they can successfully perform their "raids" without being disturbed. It can also project hallucinations of other Pokemon with this, successfully performing feats of
Illusion. The fact that they get away soundly after raiding around is the reason why many people thought they were
cloaking themselves until their psychic powers were discovered.
Their armor is a special type or armor that detaches itself from the body once it has been sufficiently damaged and would do no good. Although it comes off easily, under its old and battered shell is a lighter
Weak Armor that has a fast regenerative properties that lets it restore its original defenses after time. It has a very powerful bite thanks to its fangs and powerful jaws and its eyes are capable of seeing in heat vision. At first I decided to give it horns but those designs did not work out so well so I went with the tube like antennas instead, to give it more of that
alien body suit look; the armor design was also made with the body suit look in mind too. It has powerful legs capable of jumping and giving it lift, and also the mon has wings for flying its own weight+. Although they try to avoid being disturbed, if they decide to go after something or is threatened due to their "cloaking" failing,
they will go at their opposition as if they are ready to take out everything in their way; they will go at their objective/opposition with
No Guard and will continuously attack until they are done.
