Pom Leader

The strongest Pom-type enemy, and one of the extremely rare Leader subtype enemies, this version of the Pom not only has very high attack, defense and HP: it's also completely immune to all status ailments, and has quite a high resistance to all attack kinds, so felling it won't be an easy task. However, it's also one of the monsters that give the highest experience in game upon being defeated, so if you happen to encounter one, do your best to defeat it.

Trivia
Erroneously called Bomb Leader in the in-game Encyclopedia, but its correct name is used in-battle.
