Steven Universe is coming back in 2020 retitled to Beyond Stevens Universe

he hasn't lost it so far, I mean he's got tissues right next to his bed.

Bullshit. If this is true, I will eat my fucking belt.

No, Blastoise doesn't shoot water from its cannons, it shoots water from a not well defined spot in front of its head.

>Even in the cold subway, Steven was an outcast. "Eh fatteh!" The New Yorker slugged a fist into his fface, "You stole his sausage!"
>"Pl-Please! I had no green stuff and-"
>"That ain't no excuse!" Another, "they used to cut off the arms of thieves!"
>"Enough," Kevin chuckled from his throne. Before the apocalypse, Kevin had money and his own healthy stockpile of anti-rads, making him the equivalent of their Bill Clinton. It had only been a few months but he had already accumulated so much power and influence, Jasper herself had to take heed when dealing with him.
>Steven though, "ah, what the hell." Kevin got up out of his throne, his men making way, "suppose I can be merciful." Kevin lifted Steven by the collar, impressively showing his well sculpted muscles, "just don't steal from me again, Fatty!" With a single thrust, Kevin threw Steven out of the subway window, Steven screaming as he landed on the ground with a THUD. Steven cried and cried, the people avoiding him out of disgust.
>His few bullets falling out of his pocket. Steven had no money, begging off the street, still fat from weak gem genetics so people assuming he was hogging and hoarding away food. Finally one of the guards showed up, "hey Fatty, we've been getting reports about you." Steven shrieked as they picked him up, dragging him away to his hovel which was full of anime memorabilia, and started trashing the place.
>"STAH-" Steven got hit with the butt of the soldier's rifle, as he fell the man then knee cocked his chin, making Steven spit out blood. Then as he rolled around on the ground, the entire squad joined in stomping him. "STO-BLAH-WAAAAHHH!"
>"Eh Vlad, this kid don't got shit."
>"Right," Vlad slung his kalash over his shoulder, "you got lucky. Hahahaha! Taught you a lesson." Steven lay on the ground for what felt like hours, unable to look at the dumpster that was his home-somehow looking shittier than before.

>Years passed and Steven was still a short fat kid, getting stared down and beaten by the bigger citizens. Hell, even the slaves sometimes beat on him, the Guards assuming 'Steven' was asking for it. But the tubby boy did find an effective use of his abilities. "Ladies and gentlemen, boys and girls!" Connie called from the microphone. "Take your seats and watch kick the autist!"
>The arena was bloodstained as there had been others before Steven, but they all expired. Only he was left-forced into it due to his outstanding debt to Kevin. Steven tried to run as the gates opened, and a Watchman popped out, roaring with range. "AAAHHH-" Steven screamed as the monster bit into his arm, shaking him, blood spreading all over the stadium and even into the crowd.
>"YEAH!" The crowd cheered, throwing bottles and rocks at Steven. Steven crying for them to stop but to no avail, having suffered years of Steven and wanting revenge. Finally the Nosalis left and went back into the cage as the next round of festivities began.
>"Ladies and gentlemen," the spotlight illuminated a familiar face, "STELIO KONTOS!" The song started playing as the big man picked up and bodyslammed Steven, making him shriek-spitting out blood and teeth.
>"AAAHH-" Steven tried to run but this only angered Stelio, who grabbed Steven's right arm behind his back and twisted. Steven felt his left arm tear out of his socket and screamed, "AAHAAAAAHHH!" Barely able to hold back tears, then CRUNCH, he couldn't feel it anymore. Sastified, Stelios then grabbed Steven's right leg and slung him right into the cement wall, cracking Steven's nose and leaving a stain of blood, mucus, and mangled teeth.
>The crowd was cheering, throwing in choclate turtles, bullets, and love letters. Stelios flung up his arms to their great delight, smiling.
>"Now for the finale," Connie pecked Kevin's right cheek as Stelios got ready. Holding Steven up above him.
>"No-" Stelios slammed Steven's spine right on his knee.

It's more of a placeholder for a more original name to come.

>"Move Fatteh!" Steven felt his gasmask, it barely fit his fat face. Gerald and the other slaves occasionally slapping him upside the head. The veteran Stalker with his SWAT HAZMAT armor watching over them with a machine gun at his hip. "Ah know yous and dem darkies don' like each other, but ya GOTTA WORK!" Steven trudged more snow, the nuclear winter never letting up.
>The railways were clogged, and with the high radiation ensuring a high causality rate, the slaves were used, and unlucky nerdowells like Steven who Kevin lost in a card game. They were trying to make contact with one of the other stations, having been isolated for the better part of a decade, but to no avail. Gerald was shoveling away snow when, "AAAAHHHH!" A Gargoyle swooped in and took him away.
>The slave screaming with terror as the beast took him to a nearby roof and started tearing into him, guts even flying off."Looke like dat darkie ain't got luck. AAHAHAHAHA!" The Stalker roared with laughter. The slave's orange jumpsuits doing little to protect them from the monsters. But the monster that afflicted Steven was one that wasn't seen, oh no. And Steven only knew it got him later, after his shift ended and he went underground, his face bright red and throwing up all over the bathroom.
>"Yo whiteboi," one of the slaves snarled as he slammed Steven's fat face into the sink, "clean dat shit up!"
>It wasn't long before Steven was burning all over, made worse by him shitting blood, the Stalkers shaking their heads as they made Steven undertake more and more dangerous tasks. Figuring he was on his way out, "WAAAAHHH!" Steven cried as his hair started falling out, Stalker Uncle Ruckus slapping him across the head.
>"Oh quit yer cryin'. Man up fo' a change!"

The one unexplored thing left is seeing rose' last days and how she gave up her form. I think the last season will be all falling action.

>Steven resolved to see the sunrise one more time. He was on his way out, his body was bright red from the radiation, he had lost both ears from frostbite, his nose was permanently broken and he only had half his teeth left. Sneaking out past veteran Colonel Uncle Ruckus (no relation) who was training the Campfire Stalkers, he walked to the top of a snow covered hill. In a way the city seemed oddly beautiful even with the nuclear winter. In the distance he could even make out a strange dark creature, watching in the distance with long arms.
>Steven tried to wave, but then-a big train came. "No... Impossible!" Steven stared as it slowly chugged along, he fell to his knees as he saw who was driving it, "no..." Kevin, with his ingenious smile, his handsome olive skin, and his well toned muscles even a heavy duty hazmat suit struggled to fit, was at the controls. With Connie looking out the window longingly.
>Steven wanted to approach her, wanted to tell Connie how much he cared about her, but then... Kevin came up from behind her. Then it dawned on Steven that Connie wasn't wearing any clothes. "No..." Connie got a nasty look on her face and turned, then faced forward as Kevin began moving... Her moaning and her face in pure ecstasy. Her body pressing on the windows, Steven able to make out some very generous assets....
>And Kevin looking at him, smiling. Steven felt his spirit die, then he fell to his knees, his eyes craning into the back of his skull, his bowls letting loose and blood pouring out of his mouth. His body jerked once more, once twice, and then... Steven died. When the Campfire Stalkers found Steven, it was deduced Steven died in a pool of blood, piss, and shit.

What you did well:
>STELIO KONTOS
>Kevin VIP
>Stalker Uncle Ruckus
What needed improvement:
>More world building
>More details about the later stages of radiation poisoning
>More Jasper and Ruckus
I do think it would've been more effective if you established Kevin restoring the railways as him saving humanity. That way the utter humiliation of Steven dying as a slave would've been deeper, having been outdone and cuckolded by Kevin in his last moments.
