Metal Pom

The second strongest monster among the Poms, this formidable specimen has a pretty high defense and attack, and it also has access to the Jumping Needle Stored Attack, which can be pretty dangerous if left unchecked. It's advisable to use Grathnode Crystals and items that reduce it's attack power, or try to increase the Vanguards' attack power to the point in which they can easily take it down. Using strong Song Magic is a good plan as well.
