no most of obito skills are his own except for rinnegan and wood release. also madara passed on most of his knowledge to obito thats why obito is so strong
the hyugga and uchiha are not related. kakashi stated that early in the naruto part 1, but guess what kakashi believed the sage was a myth and the rinnegan was a mutation
Some members on the base disagree that Blaze release isnt a kkg or advance chakra nature, so i want to hear some of everyones opinion do not talk crap or say neg stuff just neg rep them if you dont like k thanks.
