Eclipo have a very simple build. Eclipo's face is black, while its "body" is white with two diamond-like appendanges on the top and bottom. Eclipo's eyes are oval-shaped with each barely overlapping onto the body, with a yellow iris.
Eclipo are the cause of solar eclipses. Along with their evolution Eclipser, the can move the moon in front of the sun and earth using psychic powers, which they use to gather their energy and make them stronger.
Eclipo are calm in nature, and avoid human contact as much as possible. However, if disturbed while gathering their energy during a solar eclipse, Eclipo and Eclipser will relentlessly attack with all the energy they've gathered, which can lead to huge problems and major injuries to whoever disturbed them. Eclipo then will have to regather all energy they've expended, which can sometimes lead to the Eclipo not having enough energy to sustain themselves until the next solar eclipse.
Eclipo mainly live in caves and other rocky areas that have been left untouched by humans. Eclipo usually only come out of their homes during solar eclipses, where thousands of their kind gather to collect the energy given off by solar eclipses.
Eclipo gather in large groups when solar eclipses occur. They seem to gather energy from the moon and sun.
