One should give the two girls all the Defense and HP possible with any accessories available. High health and Defense are needed, so it is recommended to use two Dark Knights with the Valiant Lustre Garment Grid.

Mega Tonberries in the original versions are easiest dealt with the Cat Nip strategy. If the player gets the wrong Tonberry, they cannot run from the battle to try again, but in the HD Remaster Mega Tonberry can be fought alone. As Tonberry and Mega Tonberry always appear together, it is random which one oversouls. Oversouled Mega Tonberry is the only enemy to teach the Cry in the Night Blue Bullet skill, which is notoriously difficult to learn. Should they survive the petrifying and poisoning parts of Karma, it also ignores Confusion-protection, which can especially be dangerous for L-sized captured fiends.

If the party survives its physical attack, the Mega tonberry can still petrify and poison the party and finish them off with the Karma attack that also drains half of remaining HP and MP. Mega Tonberry has high Agility and immense Attack Power and will kill a party member in one hit unless they have over ~16,000 HP and are equipped with the Iron Duke or Adamantite accessories to have extremely high Defense.
