Seth then looked at Blackbeard "Let's start this blacky" Seth summoned the fused red and blue, he immediately attacked "Electric wind spikes!" he created 10 spikes then immediately threw it towards blackbeard *swoosh!*swoosh!*swooosh!*
Seeing the incoming spikes blackbeard laughed then he shouted "Black Hole!" the electric wind spikes were sucked in by the black hole, blackbeard continued "LIBERATION!" Seth's attack were thrown back at him.
Seth already knew blackbeard's attack so he started spinning his scythe to block the incoming spikes, he then lured blackbeard away from the crowd because he knew that this would be a fierce battle and some would get hurt if they are near.
"Zehahaha are you running already seth?" he then chased towards seth, "Heh, you're really confident huh blackbeard don't think that because your devil fruit can nullify other devil fruit that you're already invincible you only defeated ace because he didn't know your full power."
Seth then converge winds on his foot then dashed towards blackbeard "Take this Wind Slash!" *swoosh!* Blackbeard dodge the slash but he was surprised that seth's scythe split into two. "Told you don't be overconfident Electric Slash! *bzzzt!*"
Seth managed to slash blackbeard's arm then seth continued his attack "100,000,000 Volt VARI!"
"Aaaaaaaaaaaahhhh!" blackbeard screamed, but seth didn't let him recover he immediately fused red and blue then slashed at blackbeard's injured arm "Destruction Slash!* *swooosh-bzzzt!* *splaash!*
"My aaarm!!! I will kill you!!" Blackbeard shouted then looked at seth menacingly, seth just smiled at blackbeard while holding his severed arm he then said "Red, time for a quick meal" blackbeard could see seth's scythe feeding on his severed arm's blood, "You'll pay for that brat!"
Blackbeard then shouted "Die in the darkness seeeeth!" he then started converging darkness behind ready to attack seth anytime, seeing this seth smiled he knew that he must fight blackbeard in close combat or else he would definitely lose.
He then said "Blue It's time to use that skill just follow my lead and don't release too much lightning" the scythe glowed. Seth then started converging winds in his body while blue also converge lightning at seth.
"It's time blue! Merge!" *swoooooosh!*Bang! Bang! Bang!* Strong winds and lightnings were raining down on Seth then suddenly a huge lightning descend towards Seth *bzzzt! BOOOM!*"
Seth was now glowing with wind and lightning circling every part of his body including his scythe seth opened his eyes then said "Berserk Form"
When blackbeard saw seth he was shocked then he immediately prepared to release his darkness attack to Seth, when seth saw this he immediately disappeared from his positon. Blackbeard panicked because he didn't know where seth was.
When suddenly he heard seth beside him "I'm here blacky!" seth then slashed blackbeard's left leg then disappeared again. Blackbeard lose his balance then fell, his darkness dissipated because he lose focus.
He was now looking left and right to find where seth is, but suddenly *swooosh!* "Aaaaaaaaaaaaah!" his left arm was immediately severed he didn't even saw seth's silhouette he then shouted "Come out you brat!! Is that the only thing you know hit then hide?!!" Blackbeard didn't know what else to do but to taunt seth and pray that it would work.
He was still taunting when suddenly seth appeared infront of him with a smile "I really wanted to play with you more blackbeard but I can't stay in this form for too long" seth then showed blackbeard his scythe, when blackbeard saw this he shouted "Noooooooooooooooooo!"
*swoooosh!* Blackbeard's head flew out of his body, seth then dispel his form he immediately plopped down breathing heavily "huuh! huuh! that form is really exhausting if I continued playing with blackbeard any longer I would be the one who will die.
Seth then told red to feed on blackbeard and take his devil fruit, after a couple of minutes a purple fruit with spiral design appeared, Seth then took it and stored in his ring. He got up then started walking towards his crew.
When he reached them he saw burgess body with no sign of life beside him was van augur and doc Q, he then looked at the battered lafitte who was surrounded by his crew he then said "Hey lafitte it's time to die now and join your captain" Lafitte was shocked seeing seth and when he heard that his captain died he was in complete disbelief.
Daz bonez saw that lafitte guard dropped so he immediately slashed at his neck decapitating him immediately seth then walked towards lafitte's body then started feeding Red, he knew that he has a devil fruit and was curious to what it was.
After finishing feeding a white devil fruit appeared seth studied it for a while then stored it, he would ask jared if he knew what kind of devil fruit it is.
He then looked towards his crew who was injured and said "Good job guys! now let's go and leave this place we can rest at the ship" they nodded in agreement then started ascending.
Ivan didn't care if Blackbeard died because he haven't heard of blackbeard's name, he then followed seth with his followers.
After ascending for almost and hour they finally reached the surface, they chose a random warship then started sailing. Ivan then went to seth and asked "Seth, how will you know where your crew are waiting" seth then showed a vivre card then said "You should know what this is right?"
Ivan then nodded and didn't talk anymore he knew that the vivre seth showed should be from one of his crew mates. Bentham,Galdino and the others were dead tired and slept on the cabin while seth was at the dining table waiting for food.
When the food was serve he was shocked because he could feel his energy recovering when he ate, he then remembered that Ivan had a secret recipe to make every food filled with energy that would benefit whoever ate it.
He then thought that after this war was over he would ask for the secret from Ivan whether he likes it or not.
