With this out of the way, let's begin.

Chapter 25

Cell, upon noticing that the time had passed two minutes, then started to destroy the islands one by one, destroying tons of them in the process before only our island remained, Vegeta only then showing up with Trunks.

"Okay, we have some time now that they've shown up... we need to stay out of sight and get out of here before invisibility wears out... Lazuli, you and 16 accompany me back to West City. We need him to get into pique physical condition to face Cell and he's in need of repairs... and Lazuli?" I asked the female android. "So you know, the ability I wish to master is the ability for me to possess someone's body and force them to do as I command. I'd need only a day in the Hyperbolic Time Chamber in order to perfect it with some assistance from my girlfriend... okay?" I smiled at her.

"O-Okay..." Lazuli said weakly as I warped our trio away and to West City, directly inside Doctor Briefs's lab, which shocked the doctor highly.

"By Jove! What's going on?!... Wait... Where's Lapis?" he asked in shock, me smiling at how he was wearing some special glasses to see the invisible 18.

I sighed and looked at him grimly as 18 started to sob. "Cell got him... he's going to try and get me too..." Lazuli cried at that.

"Please, Doctor Briefs. We need you to repair 16 so that he can be able to fight Cell while also getting rid of his 'kill Goku' programming... we need to go somewhere to hide from Cell before he starts to get desperate," I said.

But it was then that I felt Cell's power level stop being exerted and I felt Vegeta's power dwindle a bit. They were bargaining for Cell to gain his perfect form... "This isn't good..." I gulped as I looked at the scene from my mind's eye.

"And not just your pride, but for the pride of the entire Saiyan Race! I promise that if you let me reach my perfect form, I will be able to show you the truest extent of my power!" Cell guffawed.

"Very well. Go ahead and get this perfect form of yours. I'll wait right here for when you decide to face me again," Vegeta smiled before I stopped looking and went back to my reality.

"Dammit, Vegeta! He just accepted an offer to let Cell reach his perfect form instead of eliminating Cell with his increased power! Ugh, curse his stupidity!" I growled lowly as I punched the ground and formed a small dent in the floorboards at that.

"What do we do?" 16 asked in worry. Lazuli then stepped forward with a sigh and looked at me with a small, sad smile.

"The only way that we can possibly prevent Cell from destroying any more lives... is by giving him what he wants... if it means saving my family... if it means saving the world... I'll offer myself to him... just promise you can get me and Lapis out of Cell when you fight him next... okay?" Lazuli smiled at me with tears in her eyes.

I sniffled at that and placed my hand on her shoulder, ending her invisibility. "You're a very brave warrior, Lazuli... I'll make sure that you and Lapis are freed from your torment... and that you can score a date with Krillin," I smiled at her, Lazuli smiling and playfully slapping me across the face, which she was able to do, as she was part machine like Cell was.

"Yes... I don't deny that I like him... he's so cute... okay... I'm ready... take me to him..." Lazuli said as I placed my hand on her shoulder and warped us away to Cell, shocking him when we appeared in front of him and I saw that he was on his way to West City once more.

"What?! Well what do we have here?" Cell smiled at me and Lazuli together.

"Cell... monster... I don't want you to hurt anymore people looking for me. So I offer myself to you to prevent anymore innocents from dying... you'll still be defeated in the end, just like Piccolo in the Martial Arts Tournament," 18 sighed as I let go of her and Cell smiled at her offer.

"Very well. Join your brother inside of me!" Cell snickered as he opened up his tail and stuck it over Lazuli's head, her not even trying to struggle as Cell sucked her up extremely quickly. He then started to undergo his final transformation and I decided to stay and watch just to give him an offer that he absolutely couldn't refuse.

It took at least 5 minutes, but Cell had finally turned into his Perfect Form, which had a power level of a whopping 40 million. "Cell," I frowned at him as he looked at me with a frown.

"What do you want, spectral bitch?" he asked me.

"I want to make you an offer. One that you absolutely cannot refuse," I said, Cell's interest getting piqued as I sensed it. "You remember how there were the World Martial Arts Tournaments in the past, right? Like with Goku versus Piccolo and others like that? How about a new type of Martial Arts Tournament that revolves around you?" I frowned, Cell smiling at that offer.

"Oh really? You think that someone would be powerful enough to face off with me?" Cell snickered.

"We will give you 10 days to prepare a ring and for us to prepare to battle with you. If you run out of competition to fight with you, you get to do whatever you want. But if you lose, you must die by our hands. And NEVER come back. Understood?" I frowned at him.

"HAHAHAHA! You're terrible at making rules in your favor, bitch! You've got a deal! 10 days. The date will be set for September 26th and the time will be 1 pm. And I'll let you know what happens if you fail. Watch the news," Cell smirked at me as he then flew away afterwards in a huff.

"Okay... now I need to make another stop... two in fact... one to Broly and one to Annin... hopefully she allows it," I gulped as I used my warping abilities to grab my best student and then warped both of us to Annin's place, her shocked at our sudden intrusion.

"What the?! Trixie, what did I say about no outsiders coming here?" Annin asked with a stern gaze on her face.

"I'm sorry, Annin, but time is of the essence here and I need to finish training in how to possess people pronto," I said to her, Annin looking at me with a sigh before I explained the whole situation to her, Annin's face going from frown to shock and then to understanding after everything was said.

"So this Cell creature allowed us 10 days to train before he holds a tournament to face him in? And only by beating him will the world truly be safe?... But in order for him to become easier to defeat, you need extra training to release two specific people that powered him up enormously?... And you need to have us go to the Hyperbolic Time Chamber to do so in less time... I have to agree, this is certainly an issue that transcends my duties... okay, I'll talk to King Yemma into seeing if your Broly friend can guard the Furnace of Souls for a full 47 hours. That will allow us to have 2 days worth of training in the Time Chamber... and since the results are urgent, I'll have you join me when we go to meet him ASAP," she said as she held onto my hand and Broly's and all of us were warped to King Yemma's check-in station, him shocked at Annin's presence as well as mine and a living person.

"Annin?! And Trixie Gunders? What are you doing in Otherworld? You need to be guarding the furnace and you still need to complete your report," Yemma said.

"Apologies, King Yemma, but we're experiencing dire straits on planet Earth. A monster of 40 million power, the strongest in the universe, is going to destroy everything unless we stop him... but in order for me to help in defeating him, I need to train for 2 days in the Hyperbolic Time Chamber with Annin on a secret technique... but that means that we'd need a replacement to guard the Furnace of Souls while she trains me," I said to Yemma, him slamming his fists in surprise at my words.

"Great Scott! You're saying that a power level that strong is on Earth right now?! Of course I'll allow this!... But who will guard the furnace?" Yemma asked.

"Well... I'd like to..." Broly said as he timidly stepped forward.

"Who are you?" Yemma asked.

"This is Broly, the kindest, toughest, and best man for the job of guarding the furnace. He's also my number 1 pupil that I've been training," I said with a smile.

"Hmm.. I sense no evil within his heart... and he has a very incredible power level... very well. You have a deal. How long do you need to train?" Yemma asked.

"47 hours, just an hour short of 2 days. That gives us 2 years to train in the Hyperbolic Time Chamber," I said.

"Deal," Yemma said as he knocked his gavel against the desk and the clang of it made the whole check-in station jump!
