Savior Of The Multiverse (Male saiyan reader insert x massive crossover)

As Days Go By

3rd person POV
10 years since Y/n obtained a kagune

A peaceful decade has passed since the Heroes of other worlds and the Z-Fighters had fought Cell. Well...perhaps peaceful isn't the correct term to describe how things had happened..

That means the author lied to you and had something happen within the 10 years.

A/n: i swear to god if i have to repair this wall one more time...

Present time Y/n POV

It was a nice day. There was a light breeze and everything was calm, today was everyone's day off from training. Atleast until two overly excited kids ran to me and tackled me onto a hug.

Goten: "Hey Uncle Y/n! Train with us it's been forever!"

Trunks: "Yeah come on bro, you promised us!"

I ruffled their hair and gave them a smile then nodded my head.

"Sure thing guys, Goten make sure to let your mom know, she can be real sensitive on training. Especially after.. well Cell."

His smile faltered for a moment but quickly regained it and ran off to tell his mother. I sent Trunks to get all his training weights then I looked around Capsule Corp. I saw the garden that Android 16 and I had started, we were both more than happy to work on it together. My Brobot was reprogrammed shortly after I gained my kagune, we've been close ever since. I then looked at the group of other worlders. I felt guilt tug at my heart as a few of the groups were missing people, and some were gone entirely. I took it all to heart, it was my fault for not protecting anyone when i needed to. For allowing them to disappear... Shenron himself couldnt even find them. I felt tears well up in my eyes as I remembered that day...

Flashback 5 years prior
Y/n POV

I was taking Naofumi as well as Filo and Raphtalia out to do some training. Because of their strength I decided to teleport us to a forest some 20 miles away so we could train without disturbing anyone. As we were all getting into our fighting stances I felt as if something were off but I just thought it was my imagination so I ignored it. I gave Naofumi the okay and he sent Filo and Raphtalia at me, they were both incredibly fast and it made me proud to be their mentor. As Filo went to kick me in the side I jumped back and caught Raphtalia's arm as she went to slice my head clean off. I threw her to the ground and flew after Filo, hitting her in the beak and throwing her at Naofumi. As she reached him I flew above the three of them and used the Kikoho, a powerful move I got from Tien that also uses massive amounts of energy. Though being the saiyan I am and still having my tail, it hardly did anything to my energy. I used it three times and waited for the dust to settle. They got up and wiped the blood from their mouths. Then I was sent flying from a hit to my jaw and I looked over to see someone I had seen only once before...

Mira.

"THE HELL ARE YOU DOING HERE MIRA?!?"

I was about to charge him but he smirked all cocky like and snapped his fingers. I'm unsure of what move he used but it was like three of Krillin's solar flares in one. As I held my face and screamed in agony I could only wait for my vision to return. When it finally did I looked down toward the others and was shocked at what I saw. Mira had put some sort of mask on Naofumi that covered his face and his eyes were glowing red. On Filo there was an anklet that seemed to be controlling her as the mask was Naofumi. They both glared at me with their red eyes as Mira had Raphtalia by the throat and was beating her to a pulp. I got angry and went super saiyan 3, I charged at him and blasted his arm with a special beam cannon. The attack went right through his arm and he dropped Raphtalia. When he did I picked her up with one hand and aimed in the direction of Capsule Corp.

"Sorry about this Raphtalia, I hope you reach Capsule Corp. YEEEEET!!!"

I threw her in the general direction and as I turned back to face my enemy and former allies I took a claw to the gut and a shield to my face. I spit out a bit of blood and cracked my knuckles then charged Mira. Mira simply side stepped and grabbed my throat, I felt my energy drain and I began to panic. He threw me in the air and my former friends took turns hitting me toward eachother. I had returned to base form already when they finally punted me to the ground and left me in a crater. Mira smiled wickedly and the three of them went into a rift. I could only let out a disappointed whisper...

"I failed...them.. again."

I started to stand but I soon fell back over only to be caught by Gohan. He and the other Z-Fighters looked at the carnage and I weakly explained what happened. Krillin then asked me a famous question.

Krillin: "Senzu bean?"

"Senzu bean."

Krillin: "SENZU BEAN!!"

I ate the bean and fully recovered then we all flew back. When we arrived I apologized to Raphtalia for everything, she had been given a senzu before the others came to my location, following my ki of course. Raphtalia was crying at the loss of Naofumi and Filo but she insisted that it wasn't my fault and that I kept her alive by throwing her, although she wouldn't stop saying that my means of rescue were questionable at best. At that moment I came to a sickening realization. Mira was the only one I saw, but I hadn't seen Towa anywhere. Then I sensed ki behind the Capsule Corp building. I tuned to see her then looked back and Yato was missing, and the last thing I saw was a closing rift in his place. My eyes widened in anger and fear. I began to scream and I felt power rushing through me. My muscles increased in size by three times, my hair grew spiky and I could only think of one thing..

MURDER.
