"Jackpot!" is a recurring phrase/technique in the Devil May Cry series. Usually, it is said by the protagonist of an installment just before the main antagonist is finished off. The only exception from this rule is Devil May Cry 3, where it was also said by Vergil, although he was playing at the "good side" at the moment. The attack itself is an incredibly high powered Charge Shot. In real life, a "jackpot" is the grand prize in gambling.
During the first cutscene when Trish enters the Devil May Cry shop, Dante says, "The way I figure it, in this business, a lot of your kind comes around. And if I kill each one that comes, eventually I should hit the jackpot sooner or later." It is the first time it is ever heard. The phrase is again said by Dante at the end of his third (and final) fight with Mundus.
After Trish lends her power to Dante in his final fight with Mundus, Dante shouts "Jackpot!" before releasing two over-powered charged shot, one fired with his red energy and one fired with Trish's yellow energy.
There is also a track called "Jackpot" when Dante beats the final boss of the game with the over-powered charged shot.
In the end of the final fight with Arkham, Dante and Vergil first slice him with their swords, and after Ebony is smacked out of Dante's hand and caught by Vergil and they each fire one overcharged shot in their respective colors.
- Arkham: "It can't be! You cannot! Die!"
- Vergil: "I'll try it your way for once."
- Dante: "Remember what we used to say?"
- Arkham: "Don’t do it!"
- Vergil & Dante: "JACKPOT!"
Chronologically, it is the first time it is said on-screen.
In the final, twelfth episode of The Animated Series, the demon Sid absorbs Abigail's power but later has it stripped from him, and in a last-ditch effort rushes at Dante. Dante says "Jackpot" before shooting him at point-blank range.
This time the opportunity to say the phrase falls not on Dante but on Nero during his fight with Sanctus Diobolica. Nero shouts "Jackpot!" if the final blow dealt is a Devil Buster. If the player chooses not to use Devil Trigger, Nero will say "Checkmate!" or "Bingo!" instead.
In Devil May Cry 4 Refrain, Nero does say "Jackpot" after defeating Sanctus Diabolica with his Devil Bringer during the cutscene in Mission 10.
When Captain Blue gives Dante the V-Watch, Dante gains his DMC1 costume. Dante transforms by saying "Devil May Cry's a rockin' baby, yeah!" He then says "Alright, JACKPOT!"
Dante says "Jackpot" right before the final blast of his Million Dollars Hyper Combo; he also says "Jackpot.. yeah baby!" during one variation of his victory cut-scene.
"Jackpot" is the name of Dante & Demitri's Special Attack and Dante will sometimes say "Jackpot!" when he fires his charge shot to finish the attack.
In the sequel, Project X Zone 2, "Double Jackpot" is the name of Dante & Vergil's Special Attack. After the barrage of attacks from the brothers, Vergil uses Ebony and Dante uses Ivory to shoot a final shot at the enemy, while simultaneously saying, "Jackpot!"
