Chapter 4 has arrived and let's see what's going to happen.

Star City:

At the Bunker, Caitlin was sat in a corner after a Samuroid tried to capture her and Chase was still standing nearby. The elevator opened up and Barry ran out towards Caitlin and Chase, he hugged Caitlin which caught her off guard.

"Thank you, Chase." Barry smiled, Chase nodded then walked off and joined Oliver in training. "Are you okay, Cait?" Barry asked, Caitlin smiled and nodded which made Barry smile.

"I've got good news for you, Caitlin," Krim spoke up as he looked at Caitlin which got Barry and Caitlin's attention. "Mad Doctor did a scan on your DNA and it came back positive: you still have your powers." Krim informed them which made Caitlin happy that her eyes changed to ice blue and her hair became white.

"Frost?" Barry asked as he was unsure, Frost looked up and nodded at Barry and Krim. "It's great to have you back with us." Barry smiled, Frost smiled back then hugged Barry.

"You tell anyone that I hugged you, I'll deny it." Frost told him with a smile, Barry nodded while Krim chuckled. "It feels so good to be back with the good guys. Me and Caity have enough trouble with two minds in one body but three, that was a nightmare." Frost explained, she looked up at Chase and Oliver who were training and Chase was beating Ollie.

"Chase seems to be fitting in perfectly," Krim smiled as he watched the fight then his screen showed a shocked face. "Barry, there's a fire at a block of apartments not far from here!" Krim shouted, Barry nodded then picked up Krim and they ran to the Tridoron.

"I'll come too. You get any people trapped inside while I'll deal with the flames!" Frost shouted, Barry nodded as he flew his belt on and turned the key.

"Great idea!" Krim shouted as they got into the Tridoron then raced off as Barry transformed into Drive Type Speed.

Meanwhile:

Back in Central City, Ralph had received a gift from Krim which turned out to be a bike like Chase's but it was all white with red racing stripes like his Mach suit. Ralph then found a note by the handlebars but before he could get it, a hand had taken it and it belonged to Iris.

"Iris, that was addressed to me." Ralph told her but Iris didn't return it, she read it to see if she could find out where exactly her husband was. It wasn't long until Iris' eyes widened and she had found out where Barry was which made her smile.

"Thanks Ralph. I needed to know where Barry is and now I know." Iris told him with a grin. She tossed back the note then walked off to find Cisco and tell him where Barry and Caitlin were, Ralph took out his phone and started to call Barry but he got no answer.

"I need to get to Star City and fast." Ralph told himself as he got onto the Ride Macher then raced off as fast as the bike could go. To stop him from being pulled over by the cops, Ralph transformed into his Mach form which was working perfectly.

Star City:

At the blazing apartment, Drive and Frost arrived to see that the Firefighters hadn't arrived so they took it into their hands to stop the fire. They ran up the stairs and halfway up, the stairs collapsed and they could hear screaming from the floors above.

"We gotta get up there!" Drive shouted, Frost then fired a huge ice blast which extinguished all the flames. "Great one, Frost!" Drive told her as he gave Frost a thumbs up, he jumped up and started helping people to the fire exit while Frost kept on putting out the fires.

"Use Road Winter to assist!" Krim shouted and Drive nodded. He removed the Wild Shift Car then inserted Type Technic and shifted up. Drive's black and silver form then changed into a green and black form with the tire on the torso horizontally. Drive then removed the Technic Shift Car and inserted a white Shift Car that looked like a snow tank.

"Tire Toukan! Road Winter!" The Drive Driver announced a huge silver tire flew and attached itself to Type Technic then it folded down to reveal a huge panel with a snowflake on it. Both Frost and Drive then fired huge ice blasts to take out the fire.

"Well done, both of you!" Krim congratulated as a smiley face appeared on the screen, Barry then reverted back to Type Speed and nodded at Frost who nodded back. "Let's head back to the bunker. Ralph needs to talk to us." Krim told them, they nodded then ran out and headed to the Tridoron.

Bunker:

The garage door opened and in drove the Tridoron, the doors opened and out stepped Barry and Caitlin with Krim in Barry's hand. They walked into the main room to see Ralph talking with Oliver and Felicity, Barry and Caitlin waved and Ralph smiled.

"Hey Ralph!" Barry called over, Ralph waved then ran over and hugged his friends. "Krim said you wanted to talk to us, what's up?" Barry asked as he was curious. Ralph took Barry and Caitlin to the side while Krim was placed on the table next to them.

"Iris found out you're here so she's asking Cisco to bring her here," Ralph told them, Barry and Caitlin looked at each other then Barry removed his ring and placed it on the table. "Barry, is that your wedding ring?" Ralph asked, Barry nodded then looked at Caitlin.

"Originally, I was doing what the future wanted me to do but now," Barry paused as he took Caitlin's hand and smiled at her. "I'm doing what I want to do." Barry explained to Ralph, Caitlin was now blushing and Ralph was smiling. The elevator doors then opened, Iris and Cisco then walked out to see Ralph talking to Barry and Caitlin.

"What can we do for you?" Asked Caitlin as she shot the end of the sentence at Iris. "You haven't contacted us but we tried contacting you but only Ralph and Harry have spoken to us, even Joe has made time to meet up and talk." Iris looked at Barry who had walked off until Cisco opened his mouth.

"We saw the news! You three saved a lot of people!" Cisco shouted and Barry shrugged his shoulders as if it was no deal to him.

"I do that all the time." Shouted Barry. The alert alarm was ringing, Barry ran up to check it and found out who it was. "It's DeVoe; he's trying to get to Black Siren!" He shouted as he grabbed his belt and was about to get into the elevator when Iris stopped him. Ralph and Chase walked over with their drivers in hand as they were going to back Barry up.

"If you save her, what makes you think she'll stop being evil?" Iris yelled which made Barry angry.

"Frost was evil but look at what she's done now! She's saving people and helping us to stop DeVoe. If Killer Frost was evil, then she would be killing people!" Barry shouted, Caitlin was moved by his words and in a manner of speaking, so was Killer Frost.

"Barry, I didn't…" Iris didn't get to finish because when she looked up, she was looking at Drive Type Speed. Drive walked passed with Mach and Chaser behind him as they headed to DeVoe's location, leaving three members of Team Flash with different emotions flowing inside them.

A.R.G.U.S:

Outside the A.R.G.U.S facility, the three Riders had arrived with their vehicles. They saw that all the guards had been taken down by some kind of power. The trio ran towards the injured to see if they were alive but then they were attacked by several shards of metal hitting them.

"Mister Allen, how great is it to see you!" Drive looked up to see that it was Amulet Black but she was dressed in black trousers, heel boots, a black shirt and a black trench coat. "Like my new body? I had to take over this one as you took my last one." Drive's hands clenched into a fist as he knew who that was, as did Mach and Chaser.

"DeVoe!" Chaser groaned as the trio got back on their feet, DeVoe chuckled then used his gravity powers to lift the riders into the air. DeVoe started to laugh until he heard someone else laughing: it was Drive.

"Chaser, now!" Drive shouted and Chaser nodded, he took out his Break Gunner as a Shift Car slid inside it.

"Tune! Rolling Gravity!" Chaser then fired multiple purple blasts at himself, Mach and Drive which allowed them to counter DeVoe's gravity powers.

"See, we've got some new tricks too!" Mach shouted, he then tapped Chaser on the shoulder and they ran to fight DeVoe. "Barry, go and make sure Black Siren is secure!" Ralph shouted as he and Chase kicked DeVoe, Barry nodded then he ran towards the cell block. DeVoe was trying to fight the duo but couldn't as they were too fast for her.

"Keep her busy! I have a plan!" Chase told Ralph and he nodded as he took out the Zenrin Shooter. Ralph fought DeVoe as the Shingou Axe flew and landed in Chase's hand then he inserted his Signal Chaser and pressed the red button on the handle.

"Hissatsu! Matteroyo!" The axe announced as Chase fired several shots at DeVoe, Ralph back flipped and landed next to Chase. "Itteiiyo! Full Throttle!" Chase picked up his axe then ran and slashed DeVoe, the attack had caused DeVoe to feel weak.

"What did you do to me?" DeVoe screamed as she collapsed onto the floor, Chaser turned around and looked at the weakened DeVoe.

"I analysed the best way to remove your powers then inserted the formula into my finisher," Chase explained which impressed Ralph. "You've lost your gravity and telepathy." DeVoe punched the floor then looked at Chaser then she disappeared into a portal which looked like shattered glass.

"Nice one, Chaser!" Ralph congratulated him then he held his hand and waited for a high five but Chase just walked off and headed to the cells. "Really? Did he just walk past me without a high five?" Ralph asked, he then ran to catch up with his teammate and see if Barry needed any help.

Cell block:

Mach and Chaser arrived to see Drive fighting a bunch of metal soldiers created by DeVoe so they jumped in to back him up. The trio were fighting together in unison until a red and yellow blur ran past and knocked them down in one go, the trio looked up to see that the blur was an old enemy of Barry: it was Reverse Flash.

"Thawne!" Barry shouted, Thawne smiled and waved at the trio. "You two protect Laurel, I've got Thawne!" Barry shouted as he removed Shift Speed and inserted Shift Formula; the red Speed armour faded away and was replaced with the Formula armour.

"Drive: Type Formula!" Drive then ran shifted the Formula Shift Car three times which made the tires on his forearms spin. "For-For-Formula!" Drive then ran towards Thawne and the two started fighting at high speed that made them look like two blurs. Meanwhile, Mach and Chaser were almost finished so Mach opened his driver and removed his Signal Mach then held up the folded in Shift Deadheat.

"Can you handle these while I help Barry, Chase?" Ralph asked, Chase nodded then Ralph inserted Deadheat and pushed down the driver.

"Signal Bike/ Shift Car! Rider! Deadheat!" Ralph's Mach form then changed into Deadheat Mach and joined Drive while Chaser kept fighting the metal attackers with the Shingou Axe. Drive and Mach were double attacking Thawne and they were all equally fast but the evil speedster wasn't fast enough to block Mach's electric punch to the chest.

"Finish it together!" Krim shouted, both the Riders nodded as Barry turned the key and Ralph lifted up the front part of his driver then pressed the white button.

"Hissatsu!" The two punched Thawne back then Barry shifted Formula once while Ralph smacked the front half down. "Full Throttle! Formula! Burst! Full Throttle! Deadheat!" Both Riders jumped then kicked Thawne with all their power but he started to vibrate then he phrased through the ground.

"He got away!" Barry screamed then punched the wall, Chase walked over as he just destroyed the last of DeVoe's metal soldiers. "Check if Black Siren is secure then contact John and Lyla. They need to cover the entire building in Metahuman Dampers." Barry told them and Ralph made a call to John while Chase checked Laurel's cell, Barry was looking at the floor as he just watched his arch-enemy escape but Krim noticed his anger and made him concerned.

Meanwhile:

In the new secret location, DeVoe was sitting in his Thinking Chair as she was planning on a way to take down Barry Allen. It was quiet until she felt her hair blow, DeVoe looked behind to see Eobard Thawne with Marlize in his hands.

"You got my wife. Thank you, Eobard Thawne." DeVoe thanked and Thawne nodded as Marlize smiled. "Now, let's get down to our important task: taking down Barry Allen once and for all." DeVoe told them then their plan started to take down Barry.

Chapter 4 ends here and Thawne is here! The three Riders are in Star City and DeVoe has followed them. What is this plan that DeVoe has got to take down Barry?

See you all next time!
