Megasentris

The megasentri lives in universe T-38, galaxy Orgon, around the star Palatma-9, on the planet Elcarti. It operates on one sense-only head and two brain and sense heads. The top head is actually only for sensing the environment while the other two also have these functions in addition to an electrical brain. There is not such thing as three creatures glued together, only one being with multiple components.

It is big and very fast, that is actually what it mainly does in the caves. This is because it has a wide body-span compared to it's stand-up component. It has a hard time standing still before it eventually tips over. It has to move around pretty much all the time to hold balance.

History
The megasentri was discovered much later than the other electroids. People visiting the planet because of it's beautiful "tropical deserts" made stories about a beast in some caves in the area. Some people became scared and requested the S.M.O to take a look down in these caves, where they actually found a new type of electroid.
