3rd Person POV

In the City of Musutafu, A Battle was Ensuing as Momo, Tsu,  Ochaco, Mina, Yu, and Katsuki All fought as The Monster DOOMSDAY As All-might tried to beat him but was instead nearly killed if his associates didn't save him from the Alien Superweapon and he continued to try to pound him in fury with his Fists with Bone protruding through them like Draggers as the hero's tried to stop him.

 Momo Has been trying to make some kind of Kryptonite netting but her body can't seem to Make Kryptonite for some reason, Tsu tried to Wrap him with her tongue but he keeps catching it and throwing her into buildings, Ochaco keeps trying to Smash him with Floating objects that she made float but he keeps surviving everything thrown at him, Mina kept trying to shoot acid at him but it doesn't even burn through his eyes as he has faced worse, Yu kept trying to stomp on him but he just catches her foot and tosses her over and even used her like a giant club on the others and Katsuki being as cocky as ever kept trying to punch him but he just brushed it off and kept just backhanding him to the side. Mitsuki was there too but since her power only makes her look young she stands by the sidelines watching her son fail miserably the most out of all of them!

Doomsday: "I want Superman! Where is Superman!?"

Yu: "Guys He's right where's supes At?"

Mina: "I got a call from the Justice League and they say He's currently dealing with an Island with an Erupting volcano full of people so They're sending in a replacement to deal with him!"

Doomsday: "No! I want Superman! I want to kill him so bring me, Superman, before I level this entire city!

???: "I don't think so!"

Just then it was Jackson who was waiting for him to say something like that!

Girls: "Jackson!? He's a justice league Member!?"

Katsuki: "That Jerkwad!"

Just then a Brick thrown by Mitsuki hit him upside the head.

Mitsuki: "Don't talk about him like that!"

Katsuki: "Grrr, Shut up you old hag!!!"

Another brick was thrown this time with much more force!

Mitsuki: "Shut up you miserable bastard!!!!"

Doomsday: *To Jackson* "Who are you standing in my way Young Child?"

Jackson: "First I am 16 so I'm a young adult and secondly what's your game!?"

Doomsday: "There's no Game Young one! I just want to level this city to gets Superman's attention and then I can finally kill him!"

Jackson: "Then fight me! I'm just as good!"

Doomsday smirked before reeling his fist back for a punch before a green construct of some chains and shackles held it in place as he looked behind him it was Carla Shadowbelt AKA Jackson's Mom AKA (One of) The Green Lantern(s)!

Doomsday: "Let me go Female Human!"

Carla: "First, No! Secondly, That's my son your trying to hit! and thirdly, I'm not letting you hurt him!"

Yu: "Your Mom's a Green Lantern!"

Jackson: "Yep!" *He then Turns into Fourarms and charged up his Fists with Chakra* "Pucker up for your date with my fists!" 

He then punched him so Hard he sent him flying into a Building and then he got up to attack and he then Turned into Heatblast then into Ultimate Heatblast!

Jackson: "Prepare to die! Raaaaaaghhhh!!!!!!" 

He fired a powerful blast of fire from his Mouth which started Vaporizing Doomsday's flesh as he walked towards him.

Jackson: "Momo!"

Momo: "Yes!"

Jackson: "Make me some Titanium! 50ft thick!"

Momo: "Got it!"

Jackson: "Yu! Get me some Rubble!"

Yu: "Yes Sir!"

Jackson: "Tsu! Distract Him!"

Tsu: "Yes sir!"

Jackson: "Ochaco! Lift all of those Materials with Anti-Grav over here!"

Ochaco: "Yes sir!"

Jackson: "Mina! Use your acid to protect Tsu!"

Tsu: "Of course-Kero!"

Jackson: "And Katsuki Just stay out of the way while we do our work!"

Katsuki: "Why!?"

Jackson: "Because... SHUT UP!!!"

Katsuki: "O-Ok..."

As they Gathered the Materials Jackson melted it all down and while Doomsday is down he pours it on him encasing him in a tough near-indestructible metal blend! and he then Grabbed the casing as Doomsday keeps trying to bust through and started spinning at top speed until he finally let's go sending him flying into Pluto's direction and may land down there keeping him away for a while!

After that, he went back to human form and before he can even say a word the girls (Except his mother) Glomped him and of course he already knows what's going on!"

Jackson: "Let me guess You love me?"

Mitsuki/Ochaco/Yu/Tsu/Momo/Mina: "How did you know!?"

Jackson: "I got used to it by now."

He then kissed all five of them and they Blushed and continued to hug him and Blush. Clara smiles and Katsuki was Just Shocked by his Mom and also somewhat by the other girls as well.

Katsuki: "Mom!!! What the Actual Fuck!!!"

Everyone (Except Katsuki): "Shut Up Katsuki!!!"

Meanwhile In space (Near Pluto)...

Doomsday was in his self made casket in space heading for Pluto as he sulked and replanned for the Future...

Doomsday: "Forget Superman... Jackson 10's my new Target..."
