Quick theory
- Characters with the voice of all things are tied to people from the void century
- The ability/language was created by the 3 eyed tribe which is why they all have it
- Who is who
- Shirahoshi = Poseidon
- Luffy = joyboy
- Momo = the og kozuki shogun (the one that gave the mink the poneglyph)
- Oden = failed version of the og kozuki or a different kozuki of the time
- Roger = failed version of joyboy maybe like all the previous strawhat holders in between the original and luffy. Or someone else
- The pictures imu tore up also might have the voat
- Teach = the xebec of the void century?
- Vivi = the og nefertari part of the 20 families
- Even less confirmed but zoro and sanji might be the reincarnations of ryuma and sora/og vinsmoke
