Upon seeing Luffy and the rest of the inmates of Impel Dawn fell out the sky Kareem smiled. He had enough fun playing around. It was time to end this war.
Luffy and everyone from Impel Dawn landed and crocodile spotting White Beard went to go attack him because of his past grievances. Unfortunate Luffy came and stop him. While all this was happening Kareem was picking his nose.
Kareem opened his mouth and shouted "IF YOU WANT ACE COME TAKE HIM FROM ME" saying that he looked at everyone menacingly.
Ace appeared by his side once again unconscious. Luffy seeing this rushed forward and screamed out "You Bastard. What Have You Done To Ace" Kareem merely shrugged his shoulders before saying "You want to find out? Take him from me first" he fired off his conquerors haki knocking out the weaker pirate's and sending shivers down Luffy's spine.
Luffy still braced himself and went forward none the less. Along with him the white beard pirate's were attacking too. Kareem stood firm breathing in and out he decided to let out some of his power to see if they would dear to continue with there attack.
His hair turned black and his eyes red. Blue Zhenqi burst out his body piercing straight through the sky. Blue Wings appeared behind his back.
The whole battlefield went silent. The pressure was immense. Both pirates and marine couldn't bear the pressure as they were forced down on the ground couching blood. The only one left standing was Kareem. Even White Beard was on his knees but he refused to be forced down and was trying to stand back up. The same was for Garp.
Admirals, Warlords, and Commander's of White Beard Division were pressed down on the ground. If Kareem willed it he could kill them all instantly. But that wasn't his goal. He merely wished to show the difference in power. The only reason he was here was to save Ace and earn system points.
He looked down and saw Luffy struggling to crawl forward toward's him. Seeing this Kareem couldn't help but think "He really is the protagonist of this world isn't he?" he walked up to Luffy and stopped the pressure boring him down along with the White Beard Pirates.
"You are weak yet still had the courage to try to take me on. Stupid but for that I admire you. Here take him" saying that Ace appeared by his side.
Kareem took him and threw him towards Luffy who caught him. Before Luffy could throw a fit Kareem said "His unconscious he should wake up soon. Goodluck in escaping" after those words were spoken he disappeared in flash.

In the air, Kareem was flying at high speed while collecting the rewards for his mission.
Ding!

Reward: 100,000 SP
Ding!
Mission: Save Portgas D. Ace

He collected the rewards and opened up his inventory. While scrolling through it he saw many items like the storage ring of Yong Sun and his sword. There was also the lottery ticket and summoning ticket he got from saving Doryu and Ankuji awhile back.
"Now that I saved ace I should go find Douglas Bullet. He probably won't come with me without a fight" thinking about it Kareem grinned that's even better.
Using the system he scanned for Douglas location. He should have just escaped Impel Down. Before long Kareem spotted on Island with nothing but trees. On this Island, he saw Douglas in his prison outfit.
Boom!
Kareem landed out the air in front of him saying " Your Douglas Bullet right?"
"To think I would run into the Sword Saint after just escaping prison," Douglas said with a grin.
"Oh, you've heard about me? I feel honored. But sorry to say I'm here to give you a beating. We can talk after" Kareem fired off his Haki.
Douglas raised his head up and grinned firing his haki off as well. Two blue spares of equal began to clash before disbursing. Kareem was the first to make his move. Pulling back his striking hand whilst twisting it, he launches a powerful palm thrust strike while twisting his hand.
"Heavenly Destruction, Shattering Thrust Palm" the palm landed directly in Douglas's stomach blasting back.
Douglas crashed into a couple of rocks before walking out little to no injuries.
"Your pretty strong aren't ya?" Douglas disappeared and appeared behind Kareem going go push his head in the ground.
Kareem grabbed his hand and flung him over his shoulder slamming him into the ground. He then punched him in the stomach continuously before grabbing his body and throwing it up in the air. He appeared behind him and punched his body down towards the ground.
Boom!
Crashing into the ground Douglas proceeded to walk out with his shirt destroyed.
"You've got some spunk don't ya? But shouldn't the Sword Saint use a sword?"
"If I were to use my sword I'm afraid I'll kill you. Then again I just received a brand new one so let's test it" a sword appeared in his hand with a golden hilt.
Waving his hand he uttered these words " Sakura Tensho" a pink crescent-shaped blast of energy was sent out.
Douglas covered his arms with haki seeing the incoming attack. The blast reached in seconds. Upon connecting, it exploded with tiny sukara's leaving cuts all over Douglases body.
Kareem was shocked seeing this. He knew the system said he would be able to mix the skills of different zanpakuto depending on his own creativity. But he only waved his sword idly saying something fancy. He didn't actually expect it to work so flawlessly.
He looked at Douglas who now had numerous cuts on his body. Even though he was relatively fine thanks to Kareem holding back. Kareem knew he wouldn't join him unless he defeated him in combat so he decided this was the best way to do things. Then explain later.
"Douglas if I were you I would dodge" saying that he waved his hand.
Mugetsu!
A slash that seems to bring pure darkness itself was sent out. As it rushed forward it continued to split the island in half. Douglas had no time to dodge as the attack was upon him.
