Ace appears in shackles, with Sabo beside him, surrounded by many Marine soldiers.
Ace: "Sabo, what happened?! We thought you had died a long time ago! Where have you been all this time?!"
Sabo: "I'll tell you everything later.. let's get out of this place first."
Sengoku, transforming into the giant Buddha: "So you're the one who destroyed the control room and ruined our plan!"
Sabo: "It's the giant Buddha."
Sengoku: "I don't know what the Revolutionary Army has to do with one of Whitebeard's pirates for you to come here... but I won't allow any of you to escape!"
Sabo: "There's no relation between the Revolutionary Army and Whitebeard's pirates.. it's just that Luffy and I came here to save our brother!"
Sengoku, surprised: "What?!"
Memories begin of events that happened a few hours earlier. On Kamabakka Island, while Sabo was training, a multiverse travel portal suddenly appeared next to him.
Sabo: "Huh? What is this..?"
Goku, Vegeta, and Trunks emerge from the portal on Kamabakka Island.
Goku, excitedly: "Is this really another universe?!"
When they exited the portal, they found the place surrounded by flames.
Goku: "What is this place?! Fire surrounds us from every direction."
Sabo emerged from the flames, parts of his body turned into fire.
Sabo: "Who are you guys?!"
Goku: "Oi, you're on fire! Are you okay?!"
Sabo, to himself: "Don't they know about Devil Fruits? Where did these people come from?"
A few minutes later, Koala appears next to Dragon, both watching Sabo.
Koala: "Are they still talking?"
Dragon: "Yes.."
Sabo: "I understand now.. that's why you want me to help you go to Marineford before the execution of Fire Fist Ace.."
Trunks: "Yeah.. getting help from people of this universe will greatly reduce the loss of lives.."
Sabo walked to a table with many pirate photos and said: "Alright.. I don't know if something like this can actually happen because I've never heard of anything like it before.. but if we do go there, I want you to bring someone else with us.."
Sabo took Luffy's wanted poster and raised it: "His name is Monkey D. Luffy."
The memories end.
Back in Marineford, Sabo appears smiling, but suddenly a Marine soldier charges from behind him and says: "Die, you bastard!"
The soldier stabs Sabo in the back with his spear, the spear piercing through Sabo's body.
Ace, shouting: "Sabo!"
Sabo: "It's no use.."
The spear that pierced Sabo burns, and his body begins to ignite.
The soldier, shocked: "What?! My spear burned!"
Another soldier: "Impossible! Isn't that the power of the Mera Mera no Mi?! But I thought Fire Fist Ace was the one who ate it!"
Sengoku attacks with his hand toward Ace and Sabo: "I don't care who you are! Both of you deserve to die for what you've done.. I will carry out the execution myself!"
Sabo: "Watch out, Ace, here it comes.."
But just as Sengoku's hand neared Ace and Sabo, they both suddenly vanished.
Sengoku: "What?!"
Suddenly, there was a powerful crash at one of the distant buildings beside Sengoku. He turned to the building in surprise. Luffy emerged from the debris after launching himself quickly toward Ace and Sabo, causing all of them to fly and crash into the building.
Luffy, crying in front of Ace and Sabo: "Ace!! Sabo!! I'm really happy we three are together again!!"
Ace, angrily: "You idiot, you almost killed me!"
Luffy: "But I came here to save you.."
Sabo: "That's not saving, you idiot!"
Marine soldiers begin to surround Luffy, Ace, and Sabo, shouting: "Surround them!!"
Luffy: "Let's get out of here now.."
Sabo takes out a set of keys and tries to unlock Ace's cuffs: "Let's remove these cuffs first.. I hope one of these keys fits."
Ace: "How did you get my fruit's power?"
Sabo: "It's a long story, don't worry about it now.."
Sabo unlocks Ace's cuffs and they fall to the ground.
Ace: "Thank you.. now it's my turn to help you.."
Ace launches a fire attack: "Flame... Tornado!!"
He wipes out a large number of surrounding Marine soldiers.
Marine soldiers: "Impossible! Fire Fist Ace is.."
Pirates cheer with joy: "He's free!!"
A group of pirates approach Ace, Luffy, and Sabo from afar, saying: "Good job freeing Ace, guys.. let's attack the Marines and clear a path for them!"
Whitebeard, from behind the pirates: "Make way.."
The pirates move aside, and Whitebeard delivers a powerful blow with his weapon, sending many Marines flying and creating a path next to Ace, Luffy, and Sabo.
Ace: "Oyaji.."
Ace: "Let's go! Let's take this path.."
Ace, Luffy, and Sabo head down the path Whitebeard created.
Meanwhile, Trunks appears in the sky watching Rumba take energy pills.
Trunks: "He's taking those things again!"
After consuming more energy pills, Rumba unleashes a massive energy surge. He suddenly appears in front of Vegeta and punches him hard in the face. He keeps hitting Vegeta in the face with multiple punches.
Trunks flies quickly toward Vegeta, shouting: "Dad!"
Vegeta: "Damn it!"
Vegeta fires multiple ki blasts from his hand at Rumba's face. The blasts explode on Rumba, but he is unfazed and keeps punching Vegeta in the face while blasts continue to explode on him. Then Rumba lands a powerful punch on Vegeta, slamming him hard to the ground. Rumba fires a blast at Vegeta, but Goku quickly appears in front of the blast, catches it, and throws it back at Rumba, exploding in his face.
Trunks: "Dad.. are you okay?"
Vegeta: "That bastard!"
Rumba emerges from the smoke, and Goku flies at him quickly. But just before reaching Rumba, Goku flies upward fast.
Rumba, watching Goku: "Where are you running to.."
While Rumba looks up, Vegeta and Trunks appear in front of him and both punch him hard in the stomach. Rumba is hurt and glares at them, but they quickly kick him in the face. Rumba grabs both Vegeta's and Trunks' heads and flies rapidly downward to smash their heads into the ground. But before they hit the ground, Goku grabs Rumba by the leg and stops him.
Goku: "I won't let you!"
Rumba: "You're annoying.."
Rumba fires two ki blasts from his hand while still holding Vegeta's and Trunks' heads. The blasts explode in their faces.
Goku: "Vegeta! Trunks!"
Rumba fires a blast at Goku, causing a large explosion. Rumba flies backward, but Goku, Vegeta, and Trunks rush toward him and clash powerfully. Goku and Vegeta both kick Rumba in the face, but Rumba blocks with his arms. They then use their other feet to kick Rumba again in the face, sending him flying. Rumba is knocked on his back from the impact, and Trunks appears high in the sky and dives down at super speed, hitting Rumba's face with both feet and slamming him hard into the ground.
Luffy, Ace, and Sabo advance across the icy ground and glance at the destruction Trunks' attack on Rumba caused.
Luffy: "That was Trunks."
Ace: "Do you know who those guys are? They seem really strong."
Sabo: "Yeah.. Trunks and his companions are the ones who helped us get here.."
Trunks flies upward after slamming Rumba, but Rumba grabs Trunks' leg quickly and holds him back.
Rumba: "Not so fast!"
Rumba punches Trunks hard in the stomach and throws him far. Then fires a ki blast at him, which explodes with a huge blast.
Luffy and Sabo: "Trunks!"
Trunks crashes to the ground far away.
Goku and Vegeta: "Trunks!"
Rumba appears before Goku and Vegeta, grabs both by their necks. As Trunks tries to get up, Rumba slams down onto his head, smashing him to the ground. While choking Vegeta with his right hand and Goku with his left, and pressing his foot hard on Trunks' head, Rumba smirks and says: "Let's see who dies first!"
Luffy, watching: "Trunks!"
Sabo: "They helped us so we have to help them.. we promised them this.. go, Luffy.."
Luffy: "But.."
Sabo: "Trust me.. I won't let Ace die again!"
Ace: "What?"
Luffy: "Alright.. I'm counting on you, Sabo!"
Luffy dashes toward Rumba quickly.
