"He's getting away!" Yelled TimeRed.

"We can't let him have access to the time portal," TimeBlue said.

TimeYellow checked his Chrono Changer for any information if the criminals. Tac should have told them if there they're close to the portal.

"TimeRangers! Abrella has made it towards the time portal!" Tac yelled through their changers.

"Dammit, come on we should have been there by now," TimeRed grunted.

When the TimeRangers finally reach to the time portal room the door was sealed shut. They can see through the small window of the door seeing Abrella threatening the scientist to set the date of a specific time period.

"Abrella! Open this door and surrender! If you surrender now you'll won't be sent for deletion but solitary!" Commanded TimeRed.

"Ha! You think your petty offer will convince me! I know which time period I'm going to! To a time before you got rid of quirks in the world, Midoriya! And we conquer and destroy your world, so now Sentai team will never exist!" Abrella declares before vanishing into the time portal.

"Dammit! He'd gone through the portal," TimePink muttered.

The scientist in the room unlocked the doors for the Timerangers to get in.

"Dr. Kao are you ok?" The worried TimeGreen asked the scientist as the other Rangers check on the other scientist.

"Yes, just a few cut and bruise but I'll be alright but I don't about the others," said looking at his fellow scientist.

TimeGreen look over to see the scientists to see them critically injured, "We'll get them the infirmary intimately."

Soon the City Guardian lead by TimeFire to help secure the building and to take injured into proper care.

"Where's Abrella! I don't see him!" TimeFire shouted holding his DV Defender in Vulcan Mode.

"He escaped Kacchan. He went back in time," Izuku told his childhood friend/rival as he demorph.

"DAMMIT IZUKU! YOU SUPPOSED TO GET THAT BASTARD!" Katsuki scream.

Izuku sigh and massage his forehead look back at the used time portal and started to think of a plan.

"We need to follow him. He went to a time where quirks weren't owned by 0.5% of this world's population," stated Izuku.

"Then what's the plan, Izuku?" TimeBlue asked.

"Well, Itsuki, you and the rest of TimeRangers are staying here to watch over the city while I'm gone," Izuku said then looked at Katsuki. "That includes you as well, Kacchan."

"WHAT!" Shouted everybody.

"You can't be serious!" "We're a team!" "What will happen if you don't make back?" "Your wife is going to kick your ass once she hears about this." TimeBlue, Green, Yellow, and Pink exclaimed and questioned their leader.

"Fine," Katsuki said.

"EHH!" The four TimeRangers look at TimeFire with shocked faces.

Katsuki demorphs from his TimeFire suit and remove the V Commander from his wrist and toss it towards Izuku.

"Here's some extra firepower you'll need," Katsuki smirked. "You better return that to me or your wife won't be the only one kicking your ass."

Izuku chuckled and attached the changer to his right wrist. "Thanks, Kacchan, but I won't be going alone. I have chosen four other Rangers from four different teams just in case this happens. And they should be arriving now."

Suddenly four different people came in the time portal lab. Two males and two females. One of the males was tall, had brown hair and brown eyes. He was wearing a grey uniform with black boots and yellow ascot around his neck and tucked in.

The other male is a couple inch shorter than the guy next to him, has black hair, blue. He was a wearing a blue jumpsuit with the world U.A.O.H on both his arms and one red and one black triangle on both the left and right of his breast of his uniform.

One of the females had long brown hair and yellow eyes. She was wearing a black color shirt with a half of a yellow star on the left of her side of her uniform with a symbol of a dog on the yellow side. She had the name S.P.D on the right side of her chest. She was also wearing a skirt and black boots.

The last female had short white hair, red eyes and a small horn on the right side of her forehead. She was wearing a pink collar shirt with an orange jacket over the collar shirt with a small pink patch on the jacket with a symbol on it. She also wore black pants and grey sneakers.

"Lucas, Chris, Jasmine, Eri I'm glad you arrived," Izuku greeted them receiving nods from them.

"Izuku, Abrella went through the portal is what I have been told," Jasmine said.

"Yes, he took 30 prisoners with him in their frozen containment," Izuku told them. "Those prisoners fought against each of your team. That why I chose you four to join me."

"We'll follow your command Izuku," stated Eri.

"Ok then let's go. We don't have time to lose!" Lucas exclaimed.

"Your right. can set the dates Abrella chose?" Izuku asked.

"Yes prepare to jump into the portal," Dr. Kao stated as he was setting up the time portal. "Ok, it set the time period Abrella gone to."

"Okay team lets go!" Izuku order as his chosen rangers jumps through the portal. "Kacchan your in charge while I'm gone."

"I may not have my V-Commander I can still kick ass," Katsuki smirked.

Izuku smirked back, "Tell my wife I'll be back before the baby comes." then he jumped through the portal.

"Dammit Midoriya, well who wants to join me on telling Ochako that her husband went back in time," Katsuki asked his fellow TimeRangers only to receive silence.
