Prism Pom

As visible from the stats alone, this is the ultimate Pom monster. Its attack power and defense double-up that of the Metal Pom, and it also has a high speed stat, all of which can be increased even further thanks to its Self-Evolution skill. However, it doesn't have any Stored Attacks at its disposal, so the best way to fight is to defeat it as fast as possible, especially because it tends to appear alongside with much tougher monsters.
