Yellow Opera
Yellow Opera are enemies from Kingdom Hearts and Kingdom Hearts: Chain of Memories.
Yellow Opera are members of a strange family of artificial Heartless. Almost every Heartless in the family (with the exception of Wizards and Bookmasters) shares a common trait: They look very much like Vivi, and all have names referring to their color and a form of music. An opera is a theatrical work combining drama, music, song and sometimes dance. In this case, the name refers to the score for such a work.
Yellow Opera utilize Thunder magic. Because of this, the Yellow Opera absorbs any kind of Thunder magic that any party member attempts to cast on it. They are the fastest of their kind, and dart here and there like bees. Like the rest of their family, Yellow Opera are most common in Wonderland once the Hollow Bastion keyhole is revealed.
In Kingdom Hearts, Yellow Operas have 24 HP,their Attack Power is 15, and their Defense Power is 12. Sora also recovers 14 MP for hitting one, and gets 3 experience points for defeating it. However, after the events at Holow Bastion, the HP becomes 60, the Attack Power becomes 35, and the Defense Power becomes 27. Sora then recovers 43 MP for hitting one, and gets 60 expierience points for defeating it.
After defeating a Yellow Opera in Kingdom Hearts, there is a 0.5% chance that it will drop a Thundara Ring, a 1% chance that it will drop an Ether, and an 8% chance that it will drop a Thunder Shard.
An interesting paradox, the plural form for Yellow Opera can be both "Yellow Opera" and "Yellow Operas."
A Yellow Opera has been spotted in a gameplay screenshot of Kingdom Hearts 358/2 Days.
