im sowi to the ppl that do not understand i can't make it any simple bt i can say that nagato used the six paths of pain those six paths are 1) Deva Path: Manipulate gravity, attract/
repel objects
2) Animal Path: Summoning of various
animals
3) Preta Path: "energy absorbtion" capable
of absorbing any ninjutsu-related tech., therefore nullifying it
4) Human Path: Mind reading, taijutsu,
also capable of removing the soul entirely
5) Asura Path: Shape shifting/shape
manipulation
6) Naraka Path: Can summon "the king of hell" which fullfill two purposes:
interrogation and resurrection. So Rikudou Sennin (Six Realms Sage) had six different paths the 1)rinnegan 2)E.M.S 3)wood element 4)tailed beasts 5) sage mode 6)and last i do not knw but thats my guess and it makes sence if you think about it that way to cause todi has the rinnegan,sharingan and wood element so i guess i just answerd my own question so what do you think the last one is? (note* this might not be true its just what i think)
