Griffin Shadow God

Name : Griffin Shadow God

Picture:

History : This demon tried to destroy our village . The village shinobi were attacking it with everything they had . Little did they know sound village ninjas snuck into the village to kidnapped our hokage . My father , one of the hokage's advisors , alerted the anbu . He quickly went to where the griffin was and told all the shinobi to go get the hokage . They did not want to leave him there alone . He kept telling hem to go until finally they left . Once they were gone he performed a sealing jutsu . He sealed the beast in my body so that he could keep a close eye on the monster . But he did not know that the griffin was so powerful . The jutsu drained him of his chakra and finally killed him . When they came back to my father , he was already dead . They still did not know what happened to the griffin .

Info: This demon can turn into pure chakra and make you an all powerful person for a short amount of time obviously. It is able to copy any attack it sees , like the sharingan , but more powerful. It uses its giant wings in order to push itself away from the ground and away from the enemy. It is able to use shadows for strength . It is invisable to the human eye , but any animal that is summoned is able to see it .

Jutsus : Forbidden Jutsu's that are not forbidden for this bijuu only he can use it.

i thought shin will make a topic for "custom bijuus" when they attack a village? you can make this somerthing kind of like my dragon gods for example
