Metal Pom (Ar tonelico Qoga)

A more advanced version of the Pom, although this one spawns in the same areas and time as the Cherry Pom and the normal Pom. Its only difference with the others is its enormous defense and great resistance to everything. However, given its low HP, it isn't an enemy that should prove difficult to defeat.

Trivia
It's incorrectly called "Meta Bomb" in the in-game Encyclopedia, despite being called by its correct name in-battle.
