The Death Machine BIS is an enemy in Crisis Core -Final Fantasy VII-.
Death Machine BIS is a highly dangerous foe as it is far more quicker than most other machine-type enemies, and is capable of inflicting massive amounts of damage in a relatively short timespan. In addition to damage both HP and MP, it can also severely hamper the player with its Death Cloud attack, reducing their HP to 1 while inflicting Poison, Silence, Stun, and Stop. Continuously circle the foe to avoid its attacks as well as any of its cohorts' attacks, and use Costly Punch to one-shot them. If Costly Punch is not available, spells such as Graviga, Gravity, Tri-Thundaga, and Energy are suitable replacements.
Bis is a Latin prefix or suffix designating the second instance of a thing.
