The Ochu, also known as Ocho in the original NES translation, is an enemy in the original Final Fantasy. They are weak to lightning-based spells. Like many of their equivalents in later games, the Ochu's attacks tend to cause negative status effects; in this game, they can inflict Poison. The player's party can find these, alongside the related enemy Neochu, in all the rivers around the world map. They are not hard to defeat, but they are more difficult than some common enemies. Using consecutive Lightning attacks alongside physical attacks will kill it.
[view·edit·purge]"Ochu" comes from Dungeons & Dragons; specifically, it is the otyugh. The name in Japanese (and transliterations) comes from the pronunciation; it is pronounced with a short O and T (practically to a ch), making the pronunciation close to "o-chuugh". "オチュー" is the closest the katakana system can get to representing the sound without using compound katakana pronunciations not natively found in Japanese.
