Lord Ochu is an Ochu-type fiend in Final Fantasy X found sleeping at a crossroads in the Kilika Woods. The fight can easily be avoided by taking a different route, but courageous players can approach and awaken the monster.
The player should first talk to Luzzu, who will hand over four Antidotes. These will come in handy as Lord Ochu can inflict Poison along with its normal attacks. Being a plant, it is vulnerable to Fire, so Lulu is handy in this fight. After losing around half its HP, Lord Ochu will fall sleep and regenerate HP. It can be woken with a physical attack, but will immediately react with Earthquake; the damage can be avoided by Summoning Valefor, who, due to being an aerial Aeon, will evade the attack. As this is not an ordinary boss fight, if the going gets too tough, the party can escape at any time.
When it is defeated, Luzzu will hand over an Elixir if spoken to after the fight, while the Crusader to the West of where Lord Ochu was will give the party a NulBlaze Shield.
Excluding the optional ones in the Monster Arena, Lord Ochu is the only boss encountered in the game that uses the normal battle theme as opposed to the one used for boss battles. Furthermore, it is one of only two bosses (Ultima Weapon being the other) that can be bribed. The party can also Flee from the battle.
