Best example for what or how an independent avatar type SG functions is Regulus. BUT take note that Regulus Nemea is NOT an independent avatar type.

Just as the name implies, it functions independently from the user.

Utsusemis are artificial SGs based on independent avatar types. Not particularly sure what the Utsusemi refers to: the SG, the user, or both.

Utsusemi means cicada/cicada shell. Himejima Hanezu chose the word as according to himself, humans with no special abilities are just like cicada shells. They are hollowed inside.

So, to counteract that, they give them artificial SGs so they will have the means to fight against the Great House which have members that have special abilities.
