Inferno's left arm. Will regenerate even if killed, but if you leave it alone, Inferno will use Delta Hit.
Final Fantasy VI PlayStation Bestiary entry
The Ketu, formerly called Striker, is a boss in Final Fantasy VI. It is the right arm (from the player's perspective) of the Inferno.
Stats
Battle
Ketu attacks with its physical and Metal Cutter, the latter doing heavy damage to one or more targets. It should be taken out before the Rahu, the left arm. It is weak to 
Fire.
Strategy
The easiest way to defeat Ketu is to summon Catoblepas at the beginning of battle, both Ketu and Rahu are not immune to 
Petrify. If Inferno revives both arms, the player can also cast spells and summons that target all enemies, such as Grand Delta or Ultima.

Ketu is the descending lunar node in Vedic, or Hindu astrology. After the head of Svarbhānu, an Asura, was cut off by the god Vishnu, his head and body joined with a snake to form 'Ketu', representing the body without a head, and Rahu, representing the head without a body.
