Backstory: Boden is a case unlike any other. normally the Legendary super saiyan is born once every thousand years to which it was and that happened to be his father Kainkoi, who had met a saiyan woman, Tamita, and while they loved each other to the star and back the saiyan kingdom did not appreciate Kainkoi and had set a bounty for the mutant's head and so to protect her love she took them to a remote planet, Vandal its life was very balanced allowing for the two saiyans to live on the planet, and after sometime Boden was born, his power unlike any when only a few months his father sensed ki similar to his own and his mother's but vague enough to be its own, they had taught him everything from offence to defense to ki control, but unfortunately during one of the ki control training it had caught the eyes of the saiyans bringing them to the planet and fighting Kainkoi and Tamita. but unfortunately while they fought back well it had led to their death in the eyes of young Boden and to remove the bloodline they attempted to off the baby hybrid but energy grew and grew withing boden along with anger and before the soldiers could react Boden had become what seemed the legend super saiyan but green to which had led to the death of both soliders but due to the transformation it brought more saiyan soliders to attempt to kill Boden and while the green form had stood it's while it did eventually lead way to an Oozaru unlike any other, larger and stronger. Boden had won at the cast of finally being listed an outcast from Saiyans so Boden had to grow up alone but he did eventually manage to get control of his ki and gain the iconic SSJ but with that hint of more rage he would become the deadly LSSJ, only after many years would he manage to control it gaining CLSSJ and even controlling his Oozaru power into Ikari to which he soon stacked SSJ onto it gaining Super Saiyan Oozaru, Boden had pride not in the normal sense as it wasn't directed at himself but in his opponent happen they were equal or stronger than him allowing him to push limits. after an encounter like no other with a group of aliens strong beyond belief Boden was pushed to his edge, not even CLSSJ could beat them so instead of panicking Boden calmed his energy gaining and his power skyrocketed his hair turned red and he slimmed down unlocking the iconic SSJG, allowing Boden to beat the alien's and during a boring day on his home planet, Vandal, Boden tried something, stacking his energy of LSSJ onto SSJG and after some trial and error he gained LSSJB and that's when Boden sensed energies he never before knew of and one that interested him enough was the energy of Son-Goku. time periods I'd say Boden has lived is from 712-current day. Title: The Mutant Hybrid
I apologies if you are not able to understand his backstory. in summary he is a pure-blood saiyan hybrid between the mutation(like Broly or Kale) and the normal(like bardock, goku, vegeta, Tamita etc) essentially making him one of the rarest saiyan types to EVER exist. but I hope you enjoy! edit: Boden can go on par with SSJB Goku & SSJB Vegeta in SSJG
