Lol, Sasuke...
He has -
- Indra's entire being is basically Sasuke's chakra in itself so...yeah
- His chakra (uchiha chakra matched senju)
- Susanoo itself is basically a tailed beast none the less so that.
- Curse mark enzymes (flesh/cells/etc) which is why he is compatible with senjutsu
- Naruto's absorbed kyuubi cloak
- The absorption of Orochimaru/the white snake (gone, but the enzymes still remain)
- Itachi's eyes/chakra...was stated, but w/e
- Hashirama's chakra itself, and his cells
- Indra's chakra/Sage's chakra/possibly his brother's chakra as well...which is senjutsu I believe
