Inside Princess Bubblegum's castle, Hunson Abadeer is looking outside the window. His daughter and her girlfriend are already out of the place as they attempt to get Finn and Jake of their memories of the former back before Alex gets to them and kill them. The Lord of Evil has a disgust look on his face with his sight set on outside the castle. It is filled with dark swamps all over and it's getting worse with citizens getting stuck to the goo and trying to avoid the giant spikes that are bursting from the ground.
"Alex, you crazy..." he muttered angrily as a flashback comes into his mind. Now that he knows Alex is truly responsible behind his actions of eating Marceline's fries and his rampage in the Land of Ooo, that is. At that time, he doesn't recognize her of being the black robed figure who attacked him in that night.
"What?! You refuse to give me some souls after you made me ate Marceline's fries?!" Hunson yelled in anger for being duped.
"What can I say, Mr. Abadeer? You're nothing but pure evil and I'm going to vanquish you like all the monsters in this land," Alex, who is wearing a black robe at that time, wields her lightsaber.
"Really, you of all people? Have you forgotten I'm deathless?"
"We'll see about that."
The human girl charges into the demon with her weapon swinging from right to left. Hunson jumps high to dodge it and tries to make an attack.
"Karate kick!" he makes a drop kick into Alex and it's a successful one. However, this does not faze her as she gets up with a smirk on her face. She goes to him closer and stabs his chest with her lightsaber. Upon doing so, Hunson laughs sinisterly. "See, I told you. I am deathless. I can't die just by being shot, stab, falling, and even being sent into outer space."
"I see..." the human girl is still not fazed and gets her weapon off the Lord of Evil. Putting her lightsaber in her robe, she goes into hand to hand combat stance.
"Hand to hand combat, huh? Well, I like karate. I swear I will make you pay for breaking our deal," Hunson swears with anger on his face.
Alex runs towards him with a fist on her right hand, but he easily blocks it. As for her left hand, it is blocked. She just makes a smug smile on her face as she kicks him to his crotch. In pain from this, he releases her hands and Alex begins to punch him repeatedly from left to right. That is until he went down the ground. The demon got up from this moment, still not giving up.
"So you think you, a human, can beat me? Well, I will not tolerate that!" the Lord of Evil has turned his head into demon-like with his neck having two extra purple arms.
"This keeps on getting better and better," the human is not bothered by this and pulls out her lightsaber. She and her enemy charge at each other. Alex starts off trying to slash the latter with her weapon, easily injuring Hunson. However, he brushes his injuries off and tries to reach out to her with his extra arms. Alex easily cuts them down, then jumps up high to the ground and swinging the lightsaber to him, but he jumps from behind to avoid it. As she tries to attack from left to right, and vice versa, he dodges it. However, she finds a way to stab him with her weapon. "You're right, you're immortal. So, this is your fate."
Alex pulls out a purple ball and tosses it to the ground. Upon this action, a portal of some sort appeared and it's starting to suck down Hunson.
"You, what is the meaning of this?!" the latter tries to struggle while he is being sucked down.
"This is your new home, Hunson Abadeer. You will be trapped in the Nightosphere for a very good long time, but don't worry, you're still useful in my plans. When a hero comes and tries to free you from your imprisonment, you call have all the souls in the land of Ooo."
After a few seconds, the Lord of Evil has lost his grip on the ground and is being sucked down into the place where he rules the realm itself.
Back to reality, this moment really brings him uneasy.
"Marceline, Bonnibel, I hope you two could bring Finn and Jake back and stop Alex before he could take advantage on anyone else," Hunson only hoped for this outcome to come by. Only time will tell, that is.
