Cell and the Merged Zamasu began rising, not saying a word as they reached the clouds. Cell was the first one to speak up.

"So, Fusion, huh? Interesting.."

Zamasu replied-

"Indeed.. This universe needs only one God. And that God will be me.. ZAMASU!"

The divine fusion charged at Cell, immediately attempting to land a shot with his left fist, but Cell lowers himself, ducking to avoid the punch, bringing his right arm over to his left, and with a single thrust, gets the God's gut with his elbow. a hint of blood exits their mouth. Once they regain their composure, they respond to the elbow by getting Cell with a knee to the nose, which nearly breaks it. In return, the Bio Android does some good damage, by shooting back up, Cell gets Zamasu with a headbutt, before knocking him down with a punch from the left hand, intending to damage the sternum, and sending a Big Bang Attack down to wherever the Green Fusion landed as the finish.

Zamasu slowly but surely gets up from this, finally powering up, with a white aura carrying purple sparks of electric. Using the Instant Transmission Technique that carried over from Black, Zamasu got right in Cell's face again, landing multiple punches and kicks of all kinds, due to the attack being unexpected. Then, landing a kick delivered from the right leg to Cell's chin, which sends the Perfect Being shooting backwards. He then performs the divine lasso on Cell. But instead of falling to ground unconscious like Goku does in Canon, Cell's new Golden Aura explodes, getting rid of the smoke, as the holes that the spear-like projectiles made in his body slowly disappear, due to his Namekian Genetic Makeup.

Seeing the Bio Android's easy recovery, And remembering that as long as it's the bug hitting him, he can't do that, Zamasu gets a little pissed. So, he places his left hand in the air, and forms something similar to Frieza's Supernova. Cell decides he can joke around one more time before everything gets serious. He comments-

"Holy shit, he's throwing the sun at me.."

Cell was about ready to charge up a Kamehameha as a counter, but suddenly, Trunks gets in front, putting a hand out to stop Cell. He tells Perfection-

"Let me tag in.. I feel like I can take this."

Cell didn't even say anything, he simply disappears.

Zamasu shouts-

"Behold, MORTALS! MY DIVINE JUDGEMENT!"

And, throws his Star-looking ball of Ki down towards Trunks.

Now, Trunks wasn't gonna try and stop this with a puny Galick Gun, His father reminded him of one stronger than the Galick Gun. Trunks spreads out both arms, a yellow electric forming in both of them, before becoming golden balls of Ki. Once both were a certain amount charged up, The future boy put his arms in front of him. The Ki mixes together. After some more yelling and powering up in SS Rage, Trunks shouts-

"Final FLASH!"

He fires off the attack, and the two collide, creating a massive shockwave that pretty much everyone on the planet feels. At first, the two are rather equal, but then, Zamasu starts pushing a little more. He doesn't know why Trunks is trying, but for him, he thinks that's just a free mortal out of the way. Until, Trunks breaks his limits- Goes beyond what his full power should be. The Final Flash breaks through. Trunks has won the Beam Struggle.

But now, Trunks is exhausted. He needs to rest. And so he does. Dropping down to his normal state, his hair drops and becomes blue. Speaking a dropping, that's what Trunks does. Yeah, he's won the Beam struggle, but he hasn't won the fight. Letting out a mighty yell-

"TRUUUUNKS!"

A white aura with purple sparks for Zamasu forms. He was about to go over there and slice up the Future Warrior, but he feels a hand being placed on his left shoulder. The God turns back to see who it is-

Cell says, as he pulls back his right arm, forming a fist-

"Hey.."

And gives Zamasu a full force right hook, that sends the mean green machine flying. He drags on the ground a few times, before finally stopping after he goes through a building. For some reason, now, Zamasu feels the pain that Trunks' Final Flash did. And, he's covered in a strange yellow ki barrier that he didn't create. Suddenly, using the Instant Transmission, Cell is behind Zamasu again, a few yards away.

"I sent a shockwave of my energy through your entire body with that punch, now, even to Trunks.."

Cell zooms in, grabs the God by the neck, and slams him into the wall of the building he was just sent through, Before finishing it with a punch to the gut, with causes Zamasu to cough up a little blood-

"You're technically just a mortal.."

Zamasu must admit, he's never seen such a genius fighter.. He's a master of Martial Arts, like those Saiyans.. Yet he has the cunning of Piccolo and Frieza, and the smarts of someone like Bulma or Gero. The God hates to admit it, but this freak of nature may actually be Perfect.

Cell hops back once more from the Divine Fusion, as they simply stare at each other. But soon, Zamasu's anger gets to him. He yells at Cell-

"Who.. WHO THE HELL ARE YOU?!"

Cell, this time, uses the Afterimage Technique to get in front of Zamasu. His hand, not even in a fist, with a single thrust, gets lodged into Zamasu's chest. But it didn't exit the other end. Instead, a yellow glow comes through the hole Cell made- And that glow starts exiting through Zamasu's ears, eyes, nose, and mouth as the God yells in pure agony. The last words he ends up hearing are-

"I'm Perfect Cell, Jackass.."

And then, he blows up. Cell had used his own Ki to destroy the God from the inside, in the form of an explosion.

Also, no Infinite Zamasu this time. One, Personally, I don't like Infinite Zamasu. Just let the Future Warriors have their W. Two, Cell pretty much got rid of the immortal thing before killing Zamasu, so the Soul is gone too. Dropping out of this Half Way Golden Form he found, Cell says to himself-

"Damn it, I should've said 'I'm Batman'."

Anyways, Cell flies over to Trunks, who was currently getting back up. He took his time to rest up, so he can at least stand now. The boy asked-

"Is it.. Over?"

Cell replies-

"Indeed it is.. And I must admit, You've impressed me more than I thought you would've. Good job, boy.."

The two give each other a smirk, before realizing- How are they gonna get outta here? Trunks was fine staying, but he needs that Time Machine back just in case. Cell decides to use the Kai Kai to explore the explosion aftermath. Well, what do ya know? Because it was in a place where the explosion was at it's weakest, that Time Ring survived. Cell picked it up, and slipped the thing on. Long story short, the two get back to the past. Trunks and Vegeta have a little spar, that Trunks actually almost wins. Goku is kinda jealous Cell had all the fun, but he'll get over it.

Cell promises Beerus that he'll bring the Ring to the Supreme Kai, but he doesn't. He thinks it's a neat little thing to have. Cell did know that Goku was talking about some kinda Multiversal Tournament coming up, so perhaps it wouldn't be limited to their own Universe 7 when it comes to finding recruits.
