Luffy defeating Akainu with a Gomu Gomu no Giant Gatling.
Pirate Warriors 2
During the "Return to Thriller Bark" Arc, Moria is on the verge of being defeated by the heroes, but he summons even more zombies to his aid. "The longer the battle continues, the more zombies I can summon." Cue a stream of water one-shotting them all. Jimbei arrives and says: "It seems zombies don't like salt." Moria starts attacking Jimbei to steal his shadow, but he parries the attack and one-shots Moria with a Shark Karate Strike.
During the Return to Punk Hazard Arc, Akainu arrives and the Straw Hat/Whitebeard Alliance is cornered by the Fleet Admiral's strength. Just when a few members are about to be melted....the attack freezes. Aokiji appeared. And his response to Akainu asking why he's there? I missed seeing your face..
Brook shrugging off Mihawks's attacks count as one.
During the Marineford War, Akainu is driven into a corner by the full force of the Straw Hat/Whitebeard alliance and prepare to counter attack against the Whitebeard pirates. Ace comes to block the incoming attack, saving a lot of his crew in the process as he himself gets hurt by the magma attack. Luffy come to his aid, only for Akainu to leap on both Ace and Luffy with a magma punch. When everyone expect Ace to suffer the same fate he did in the manga... Whitebeard pulls a Big Damn Heroes, stabs Akainu's with his spear and counterattacks with a Quake Punch to the guts.Ouch.

The Final Chapter, which is PW 3's game-exclusive rendition of the Dressrosa arc given that at the game's launch, the arc was still going. It follows the canon right up to the point where Law's negotiation attempt in Green Bit. Following that, Kizaru has teamed up with Fujitora to capture the Straw Hats/Law alliance while the alliance itself is aided by Kuzan, Luffy fights Burgess for Ace's Flame-Flame fruit when Sabo arrives and takes on Burgess himself. When the Straw Hats go to destroy the SMILE factory , they find none other than Blackbeard himself guarding the factory as a result of an alliance with Doflamingo. It all culminates in an epic showdown against Doflamingo in the throne room which ends with Doflamingo making clones of himself, each of which is taken out by one of the Straw Hats, Law, Sabo and Kuzan, ending with Luffy and Sabo launching a combined Red Hawk/Fire Fist to end Doflamingo for good.No Problem with Licensed Games indeed!
