The Great Malboro of Final Fantasy X is a stronger version of the standard Malboro, which is encountered in the Omega Ruins and also Inside Sin. When fought inside the Omega Ruins, Great Malboro will always begin every battle by ambushing the party and unleashing Bad Breath.
After the first turn, each of Malboro's three main attacks: a gastric juice attack on a single character; a volley of gastric juice hitting all characters, and Bad Breath, all have an equal chance of being used.
Since Bad Breath can inflict status effects like Poison, Confuse, Darkness, and Berserk, it is a good idea to equip active party members with armor that resists some of these effects. Having one active member equipped with a First Strike weapon will make the fight slightly easier. If that character has Delay Buster, the player can even defeat it before it takes its first turn. If this tactic is used, the Great Malboro will counter with a chew attack, which causes fairly heavy damage to the character that delayed it.
Having someone with a First Strike weapon that knows Provoke is useful; if provoked before it makes its turn instead of using Bad Breath it will use a rather weak attack that hits the entire party for less than 1000 damage, giving the player plenty of time to finish it off before its next turn. Having a member doublecast a Fire-elemental spell is also effective, as Great Malboro is weak to Fire. If Yuna has First Strike, she can Summon an aeon (which are immune to status effects) before it takes its first turn. A player merely trying to traverse the Omega Ruins can also give First Strike to any character that knows Flee.
