An @sspull is when there is no story and or training.
Susanoo is apart of sasuke's hate (or anything the uchiha gives a shet about and live for) which started since part one, not an @sspull.
Sasuke amaterasu was gained by his loyalty to his team, and he thought about team 7.
Kirin was thought up at the beginning of shippuden, he obviously trained off screen because he isn't the main character.
Nothing but Sauske's swordsmen skills is an @sspull because it was random as hell.
Naruto, everything is an @sspull, hands down.
Minato....everything but shushin, hands down.
Madara, LOL EVERYTHING but MS and EMS. Like wtf is with that taijutsu?
Hashirama, sage mode, we've yet to see a story or anything.
Tobirama, shadow clone jutsu, and or edo tensei. Most likely anything else he does is an @sspull unless its water style.
Kabuto, nothing but sage mode, its normal to follow in your mentors footsteps (sasuke dumb af in other words).
