|First Appearance||X = Ben + 2|
Sylonnoids are humanoid in shape, and seem to be covered in a metallic substance. So far two color schemes, silver and gold, have been seen. The only organic part visible is a round pink brain which protrudes from the tops of their heads, which seems to be in some sort of dome. Their domes have a circular piece affixed to the forehead.
They have jagged angular eyes, conical heads which taper at the chin, and lines on their faces which run down the center, around their eyes and mouths. They have only been seen wearing black clothing with metal pieces.
Powers and Abilities
Sylonnoids are shown to be able to survive in space, due to their protective metal exterior.
Sylonnoid comes from the word "solenoid".
