Interesting tradition from manga and anime: declare the name of your next move to freeze your opponent in shock. ^_^

RurouniKenshin: Hiten mitsurugi ryu… double reversed rotation triple slash!
Enemy: awestruck paralyzed by what they heard

VoltesV: Ultra magnetic top!
Foe: shaking in fear

YuyuHakusho: Ray gun!
Taguro: eyes wide in shock

What other memorable move declarations can you remember?
