Chapter 21 A new Hero Blooms

I don't own Kamen Rider Build or Avengers: Earth's Mightiest Heroes

Few days have passed and MJ was still asleep after she was exposed to the gas, she was in the Team Build base and was on the bed with a heart reader next to her.

"I'm so sorry MJ."Ryo said next to her.

He then gets a call and answers it."hello."

"Hey Ryo, how's the girl?"Tony asked.

"She's stable but I don't know when she will wake up."Ryo said.

"Are you sure you don't want her to be with a doctor, I have a friend that's also a scientist."Tony said.

"I'm sure, I'm the only one here that knows about the Nebula Gas, she needs me."Ryo said.

"Alright, I'll tell the others."Tony said and he ends the call.

Ryo goes up to MJ and does another scan on her, he then tries to see if any of the fullbottles could help but the strangest one was Rose was a match with her.

He then goes to his desk and takes out a device he made, it was a multiple roses like that of a garden with the bottom being roots, he then puts it next to MJ."I hope this will make you safe."

"Ryo."he then sees Daredevil come in."we have a problem in the city."

"Alright."Ryo then runs off with him.

At the city Team Build arrived while Ryo was Grease with the rest in they're transformed states and they saw two robots there, they were both bulky with them having one eye and green bodies while having claw arms.

"Looks like we found new enemies."Grease said.

"Target locked."they said and they opened they're shoulder pads to shoot missiles at them.

They dodged them while Engine and Remocon shoot at them, they raised they're arms and blocked them, Superpro then tackles one but gets pushed away, Engine charges at one and starts to punch at the robot but it's friend shoots him away, then Grease goes after one with the twin breaker and sees it get hit by a blast, he then sees the Avengers coming.

"Hey need some help."Ironman said.

"Well it would be good."Grease said.

Captain America then sees Castle working with Owl and Stag blocking the blasts from another robot."you found a new member."

"Yeah, I'll introduce you to him later."Grease said and they start to attack the robots.

Hulk and She Hulk then charge at them but then they changed modes to have green lights on they're bodies, then they punched at them making them blink but then the robots punched them away.

"Wait a minute, these are design to absorb the shock from they're punches and use them back at them."Ironman said.

"Well smart observation there Einstein."Castle said."got anything better like how we can crush them?"

"Is he always like this?"Wasp asked Grease.

"Yes, but you get used to him."Grease said.

"I know I did."Daredevil said.

At the Team Build base MJ was still in the bed and she wakes up, she then gets up a little hurt and she looks around."Ryo?"she calls out to him, then she sees the Rose Garden on the side of her bed and grabs it.

She then gets off the bed and walks towards the main room and sees a tv, she turns it on to see a news report of the Avengers and Team Build fighting two machines that seemed to be made to counter them but then it stopped.

"Oh no."she then looks at the device and remembers how Ryo transforms into Cross-Z, she then sees Build driver and takes it with her.

The Avengers were still figthing while the streets were empty because everyone ran away.

Grease was sent to the ground while the others got pushed back.

"Who ever made them was really prepared."Ironman said.

"Oh really."Hawkeye said.

"Who could have been able to make them."Grease said.

The robots look at them but then looked up, they then saw where they were looking and Grease got surprised, MJ was walking towards them with the Driver on her waist.

"Wait why does she have that?"Ant Man said.

"I won't allow you to harm my friend."Mj said.

"Mary."Grease said and he throws her the Rose fullbottle.

She catches it and rotates the cap, she then shakes it and inserts it in the device.

BLOOM!

She then inserts it on the driver.

GARDEN OF THORNS!

She then rotates the driver with the pipes appearing making the halfbodies of Rose only female shape, then a circle appears around her with many vines going around her.

ARE YOU READY?

She then puts her arm up and said."henshin."the suit attaches to her while the thorns go around her.

SEIGI NO TANE O UEYOU! THORN! YEAHHH!

They then saw the suit has a armor of thorns on her chest while she had a crown making vines go down the back of her head like hair, her arms have green braces and her feet have green boots.

"What the?"Ironman said.

Grease was happy and said:"MJ."

"Kamen Rider... Thorn."Thorn said.

"Thorn is not appart of the database."the robots said and they charge at her.

She then shoots two whips of vines at them hitting them, she then jumps over them while the others got up, she then lands next to Grease and said:"thanks for leaving this for me."

"Hey I noticed how you might need it so I'll make one for you later."Grease said.

"Alright."Thorn said and she then charges at one of them.

The robot shoots at her and she then dodges the beams and rotates the lever.

READY, GO!

She then punches the ground and many vines trap the robot making it struggle while she jumps to the sky.

BLOOMING FINISH!

She does a flying kick with her right foot getting covered in rose petals, she then hits the robot making it explode.

"With one attack."Ironman said.

Grease then charges at the last one and hits it away with the breaker, she goes next to him and Grease gives her the drill crusher."here you might need it."

"Alright."She nodded.

He then changes the mode.

ATTACK MODE!

He then takes out the robot fullbottle and sclash jelly and inserts them.

TWIN!

She then takes Helicopter and inserts it on the weapon.

READY, GO!

They then charged up with Grease's weapon being covered in gold energy while her was spinning around making a spinning blade with petals coming out of it.

VORTEX BREAK!

TWIN BREAK!

They then charge at it and hit it at the same time, the robot starts to crack and it explodes, they then turned around with Thorn putting the weapon on her shoulder.

Later they were at the mansion out of they're costumes and Wasp said:"wow Mary that was pretty cool how you just took out one of those bucket heads like it was nothing."

"Thanks, I was surprised that I was able to be that strong."Mary said.

"So are you going to join a team?"She Hulk asked.

"Well I would like to be with Ryo so I'll go with his team."Mary said.

Tony frowns a bit and Steve said."don't need to be jealous soldier."

"Me jealous, ha."Tony said.

"It looks like it."Dean said going in between them."you know you might have all those fancy stuff with the suits but I can still kick you're butt."he then looks at Steve."also who puts this old man here."that made some of them chuckle."he likes to ramble on and on how the old days were good, but if me and the guys were in you're time you wouldn't even be 120 years old."

Steve chuckles and said:"a little eager aren't we."

"Hey I can kick you're ass too."Dean said.

"Language."Steve said.

"That I would like to see."Hawkeye said.

"Yup."Hulk said.

Tony was thinking what Steve said and asked."didn't anyone notice Cap just said language."

"Oh so you want fight."Dean said.

"Okay, how about in the ring."Steve said.

"This is going to be good."Grant said to Adrian.

At the ring everyone saw Steve fighting against Dean and he is doing way better than Tony, they were punching at each other and Dean pushes him down and does a leglock, Tony was side of the arena."come on Cap show him who's boss."Dean then turns then lock around to be on his belly facing Tony and gives him the finger."hey Cap hates that."

"I like this guy."Hawkeye said.

Steve then breaks the hold and throws Dean to the ropes but then he gets his nose grabbed while he screams in pain. some of the guys were laughing.

Dean then lets him go and goes towards a corner, Steve then sees Dean lying on top of it.

"Oh the disrespect."Grant said.

Steve then charges at him and Dean then moves out making Steve fall out of the ring and lands on Tony which made them laugh.

"Ow."Tony said.

"Sorry, I just never faced anyone like him, he's not even doing this seriosly."Steve said.

"Yeah, I can see that."Tony said.

Steve then jumps up to the top ropes only for Dean to trip him making Steve hit his crotch on the ropes and he screamed, some of the guys groan in phantom pain seeing that.

Dean goes up to Steve and puts a hand on his shoulder."it's alright."he then throws him back to the ring.

Steve got up and then gets a ddt to the mat, Dean got up with a smile."I told you, even with that super soldier drug I would still kick you're ass."then he gets a call and takes out his phone."hello, oh hey babe."

Steve got up and said:"you're really taking a call in the middle of the fight."

"Yeah, yeah, okay I'll be home later."Dean then ends the call."sorry about that, but my girl wanted to know where I was."

"Okay well let's just finish this."Steve said.

"Okay."Dean then starts to punch at Steve while he did the same.

"This will take a while."Ryo said.

He then sees Grant and Adrian recording the fight."who are you recording this for?"

"Oh for our buddies like Laura and Pixie."Grant said.

"Oh them."Ryo said.

"Yeah they will like to see this."Adrian said.

Pepper came in and saw the fight."what's going on here?"

Kai goes up to her and said:"Dean wanted to show that he could beat up Captain America so they're now testing that."

She then grunts and sits next to Ryo."I can't believe them."

"Yeah, and Tony is even betting Dean to lose."Ryo said.

They then saw Dean throw Steve to the ground and motions Mick to give him something, then he gives Dean a rolled up tarp only for him to unroll it to reveal a banner with the Team Build Logo.

"Okay no self promotion in our mansion."Tony said.

"He really likes you're team."Wasp said.

"Yeah."Ryo said.

They continued to fight for a while until it ended in a draw but Dean still said he would win, they went back home with Mary Jane getting a driver of her own while Ryo kept his Build Driver.

Note:Mary Jane is now a female Kamen Rider also don't expect all the stories to have a female rider like Den-O and OOO, robots are made to show off Thorn's skills and Dean got to fight against Steve and was winning for a bit since he was more savage in his fighting style.

The phrase in the transformation:"SEIGI NO TANE O UEYOU!" means plant the seeds of justice.
