Eye of Machine God

The ultimate Ball-type monster, the Eye of Machine God is pretty much the synthesis of the best abilities that the members of said monster kind have, excepting for the Big Guarder and the Satellite Star, couple with extremely high stats. Aside of the fairly standard Laser and Ice Beam attacks, it can also hit party members with random status ailments through its Mystery Ray skill, can regenerate its own HP, and finally, can also use Electromagnetic Laser, the most common Stored Attack in this monster type. Due to the above, you'll have to fight carefully and try to defeat it before it can become a problem.
