It was late morning like at 9:57 and Ruby was waking up slowly and soon looked at him asleep and to see his arc reactor on his chest and she puts her fingers on it feeling it as it glowed a bit until it fully lit up and Y/n was waking up and was getting a shirt on then helps Ruby get on the Wheelchair and toke her to the basement to began the scan so Y/n can make Ruby's legs

As they were in the process of finding the right size and length for the legs Ruby was looking around the basement till she saw a display case of suits

Ruby: "What are those?"

Y/n: "Those are The IronMan suits my father built them he was a hero but he died saving the world from an invasion from the Grimm."

As Ruby listens to this Y/n has already worked on the schematics and Ruby smiled at this. So Y/n worked on Ruby's new legs for a full 5 months with some rest but Ruby helped him during those days that she could and but on the final day which Y/n was finally finished the robotic legs and soon began to put them on Ruby

(The male reader did it like this)

As Ruby was watching Y/n attaching her legs and attaching them to her she couldn't held back her tears of joy just to finally remember what its like to walk again. After Y/n attached the legs he helped Ruby with her first steps with her new legs and Ruby smiled happily and hugged him

Ruby: "Thank you Y/n for this."

Y/n: "Your welcome Ruby."

As Ruby smiled still and tried walking by herself she mostly enjoyed her time walking and slowly began to run and as well as active her semblance and was fast around the basement and Y/n smiles at this and looks at his family photo before looking back at Ruby

Y/n: "Well lets get going you have to tell everyone the news right?"

Ruby nodded and packed up her stuff and Y/n went with Ruby to Beacon as there were tents with surviving people from other villages as the rest of Team RWBY and JNPR came over to see who it was

Yang: "Exuse me but who are you?"

Blake: "And where's Ruby she hasn't talked to us since five months ago?"

Y/n smiled as he stepped aside for them to see Ruby walking out with her new robotic legs and Ynag had tears and ran up to her and hugged her as she cried

Yang: "I missed you Ruby."

Ruby: "I miss you too. I missed all of you and thanks to Y/n right here i can walk again."

They all looked at Y/n and thanked him for helping Ruby. But as Ruby was looking around she never noticed Weiss at all but as once everyone got back to helping the survivors and Ruby smiled at Y/n and kissed his cheek as he soon blushed as Ruby ran off to help the other's but as Y/n looks at Beacon he soon leaves on the BullHead while sending a message to Ozpin. But as Y/n got home all he heard was atlas ships flying around him and began to fire at the house and Y/n gets behind something to take cover as when Friday activated something

Friday: "Initiate Mark 100"

Y/n: "Huh? Mark 100?"

As when Y/n said that pieces of some sort of armor started to form in front of his eyes as he couldn't believe it himself

After the armor was formed it put Y/n inside of the suit as it checked everything and it showed white fang soldiers in it shooting him as Y/n tried to fight back by shooting some sort of energy blast from his hand and shot some missiles till the floor started to break under him making him fall into the ocean. As the white fang did a search but only to find no sign of Y/n. But as they left the suit flew out of the water

[Friday]: "Where would you like to go Y/n?"

Y/n: "Beacon and im gonna take a nap."

The suit went to auto pilot after he said that and flew on its own for 3 hours until the suit lost power and crashed into the ground in a forest with Y/n still knocked out but until he was being taken away by someone or something to a shack in a forest....

Meanwhile at Beacon

Ruby was looking for Y/n as she soon went over to professor Ozpin to see footage of the building collapsed Ruby had tears in her eyes but Ozpin knew he couldn't be dead that easily so he checked the camera's to find that he flew away from the reckage and headed to somewhere in Remnant on his way to beacon

Ozpin: "Don't worry Y/n we will find you."

Ruby: "Who would even do this and hunted him down for what reason?"

As Ruby asked that she soon walked away from the dorm as he felt something in her dress and as she pulled it out as it was a photo of Y/n and her of their fun times over the five months as she walked into her dorm she looked out the window hoping that she'll see Y/n again...
