If there will be Jinchuriki's my ideea might help
The Bijuu's are placed somewhere on the map
Let's say you defeat a Bijuu
You have defeated him ,you'll get the Bijuu like a Item
Now you can seal the beast in a player with a specific jutsu.
Skip
The Bijuu is Sealed in A Player
After The Bijuu is sealed in a Body ,the respective player becomes a Jinchuriki...
-Hi's chakra regeneration will increase
- If hi's Chakra goes to 0 he will gain a Bijuu Chakra Boost
- Every Bijuu will have a specific unique ability
eg: Kyuubi [Fox Regeneration ( HP Regeneration ) ]
Other Players will start Hunting the Bijuu for hi's power.
If the Jinchuriki's is hurted (player goes to 20HP%) the bijuu will raise up and take control over the Jinchuriki's Body [ You'll start the Bijuu transformation , regain 100% HP AND MP )
-You won't be able to peform Jutsus wich require a High Chakra Focus becouse you can't control the Bijuu Chakra.If your HP goes to 20% Again you'll transform again( Regain 100% HP AND MP)
but lose control of your character , the bijuu will do random attacks.
The Bijuu transformation can start from the 1st tailed(first form ) to 9 tailed form. ( ultimate form )
.You will have control just over the first form.Exception is Shukaku , where the first transformation will make you look like
- Spoiler:
and the Final Form like - Spoiler:
[
When the Bijuu reach hi's full form the Jinchuriki will die and the Bijuu will walk free Again.
Let's say your Bijuu is Kyuubi , if he reach 9st tailed form you'll die and Kyuubi will walk free again
If you're Sanbi (3 tailed) , when the Bijuu is 3 Tailed you'll die and Sanbi will walk free again
You're Shukaku , when the Bijuu is full 1 Tailed you'll die and Shukaku will walk free again , got it?
With more wounded the Bijuu is , more Tails he will gain.
To avoid this ^ you must take control over the Bijuu like Naruto and Killer Bee did. You must fight alone against your Bijuu and take him 40% hp.
If you're Kyuubi you'll have a quest to learn the Bijuu Mode ( Like Naruto Learned).
If you're bijuu is not Kyuubi you will learn:
- Bijuu Transformation ( you'll be able to transform in Bijuu without losing control of your character)
-Bijuu Dama
But it wont be so easy to learn those things ^
Now once you mastered the Bijuu players will need to take your HP to 10% and use a special jutsu who will neutralize you , after that they can extract the Bijuu from you.
