AN: 2000's kids will know the nostalgia of Beyblade, Naruto, dbz, yu yu hakusho, pokemon, bleach, one piece, etc. Used to watch it on cartoon network.

AN2: I am taking most of the info from the fandom websites, so kindly forgive me if there is some wrong info.

AN3: My English is not good. Just doing this shit so that I can take some time off studying.

AN4: This will be collection of fanfic ideas from some of the anime mentioned above and high school dxd. I loved hsdxd. It has great LN, but anime is not that good. And there is so much room for world building, still not explored.

AN5: Constructive criticisms on my ideas are most welcome.

Chapter 1: Tyson Granger in High school dxd (This idea just came to my mind when I watching Beyblade amv on yt.)

It has been 50 years since the last battle between Tyson and Kai. Their group of friends went to pursue their own carriers, with Kenny being the most famous became a world-famous analyst of Beyblade tournaments (Beyblade burst and onwards). Tyson is continuing his grandfather's legacy of continuing the dojo. Where Kai went after their last battle is unknown.

When Tyson is checking his mail box, he finds a letter addressed from kai. He is shocked to find that Kai contacted him after 50 long years. He is both excited and angry. He opens the letter and finds that Kai has challenged him for a bey battle (how you want to express his emotions is upto you).

Tyson finds it hard to ignore the letter send by kai. He was still struggling to forget his past and was finding it hard to control the adrenaline rush for a bey battle.

Tyson looks at his most trusted partner Dragoon, which he still cleans regularly (he replaced his family heirloom sword with his beyblade). Dragoon gives his permission for the battle by shining.

Kai vs Tyson (a few days later) (you can decide their meeting place)

Tyson and kai stares at each other, not knowing what to say. So, they decide to let their Beyblade do all the talk. They nod to each other and with perfect sync they let their Beyblade rip.

(Their battle your choice)

They have completely unleashed their bit beast's power. Kai is winning the bey battle and Tyson is being pushed back. Tyson and kai are having fun, they forgot for 50 years. Tyson feels that even if he die today, he has lived his life. So, Tyson starts burning his will power (you will know later) along with his life force to fuel the Dragoon. This bought a smile to kai's face, so he also starts doing the same. The typhoon of Dragoon and flames of Dranzer collides with each other. The match between them is so intense that the whole fields starts getting destroyed, but none of them cared. They started fueling their bit beasts with more power while smiling towards each other.

The power became so intense that a huge explosion occurred. Both Tyson and kai breathed their last breath having a time of their life. Kai went in the cycle of reincarnation, but something different happened with Tyson. His bit-beast unable to see his most loved one after coming from dxd universe turned himself into sacred gear (he didn't let the god convert him into sacred gear, so he jumped universe where most of his powers were restricted due to laws of Beyblade universe) and attached himself to Tyson's soul to enter the circle of reincarnation with him.

Due to fusion of two souls of different universes, there was 50:50 chance of ending in either of universe. Tyson get's reincarnated in dxd universe as issei's brother. (Tyson kept his original appearance). Both Issei and Tyson were born at the same time.

Suggestion:

1. 1. Both Tyson and issei should be present in the fic.

2. 2. Issei's sacred gear will be same as in original and he will become a part of Gremory peerage.

3. 3. Tyson's sacred gear will be Dragoon.

The suggestion is upto you. Thx for reading this shit.

I will be posting Naruto x dxd idea next.
