Ryoga (U93)

Ryoga isa mystical dragon bent on destruction of all life dated to exist 10,000 years ago. He flew over the universe destroying civilization after civilization until he came to Earth. He was stopped by Amaterasu and was sealed away in a book he stayed in that book in amaterasu's cave for 10,000 years until Brudikai found the book and opened it dispite his mother told him countless times not to. Ryoga was free to roam the Earth again. To thank the saiyan for freeing him Ryoga took over his body unlocked a transformation called Super Saiyan of the Black Dragon.

Ryoga set his sights on west city but when he arrived he couldn't destroy a thing. Brudikai's idiot brain and pure heart tainted ryoga's dark heart, and because of that Brudikai got his body back. Brud pleaed with his mother not to seal Ryoga back into the book if he could prove that Ryoga changed. Brudikai succeeded in proving that Ryoga changed. The new Ryoga who was once destructio incarnet, is now a sarcastic, logic obsessed, only destroying things when needed, dragon  Ryoga bonded with Brudikai not just by friendship but through his body. If Brud ever were to die Ryoga would Die too. Ryoga lives at Capsule Corp. with Brudikai and his family
