Drains HP with its Doomsickle attack.
The Twinscythe, also known as Toe Cutter, is an enemy in Final Fantasy VI.
It normally only uses physical attacks, but when attacked has a chance to counter with Drainsickle, restoring its HP. Fira and other Fire-elemental attacks work well against them, as does Strago's Aero Lore.
1st Turn: Attack (66%) or Nothing (33%)
If attacked by anything: Drainsickle (33%)
