The Rakshasa, also known as the ManCat in the Nintendo Entertainment System, is an enemy from the original Final Fantasy. It is not a powerful enemy, but will try to inflict many status ailments to the entire party, as they cast a wide array of spells like slow. Wearing Ribbons protects against these inflictions. Its most dangerous attack is Fira, but that is negligible and they can still be taken care of with physical attacks alone.
Rakshasa are gigantic demons from Hindu and Buddhist mythology. They are powerful beings aligned with evil, who live on human flesh and spoiled food. The creatures make an important appearance in the epic of Ramayana.
In Dungeons & Dragons, Rakshasa are evil shapeshifting fiends, tall humanoids whose natural forms commonly have the head of a tiger. They are powerful users of magic. The original Final Fantasy derives a lot of influence from D&D.
