The Tonberry is an enemy in Final Fantasy VI. It uses Traveler every turn, doing Defense-ignoring damage to a party member. They Counter every attack with their special attack Knife, doing heavy physical damage, followed by Traveler. This combo is powerful and will likely kill any party member it hits unless they are at a very high level. The Tonberry is vulnerable to the Imp spell, which will prevent it from using Traveler, but it will always get a critical hit with its normal attacks while imped. It is also susceptible to Petrify. The Break spell will fail due to the fact they are immune to Instant Death, but Gau's DeepeyeRage works well, as its Dread attack (which induces Petrify) does not check for Instant Death protection like Break does.
