Skull Eater (Final Fantasy V)

The Skull Eater is occasionally encountered in Jachol Cave. Although it has only one HP, its high evasion and defense makes it extremely hard to hit, and its attacks can easily kill a party member. However, it can be killed with the Ninja's Throw ability. It is also easier to kill after the worlds have merged, as the party's strength will outweigh its evasion.
