Kingdom Hearts KHFM Phantom... Nobody??? sort of?

Okay I just found out how the phantom looks in KHFM And the first thing I thought was JOLY CRAP IT LOOKS LIKE A NOBODY
The color scheme is very nobody like and overall it resembles

Spoiler

The final Xemnas boss in KH2

But the phantom is... weird and Although it is a heartless it seems to exhibit characteristics of both nobodies (lacks physical essence and in a sense doesnt exist,new color scheme) and heartless (The emblem on its back, the ability to curse a person and steal their heart) while at the same time exhibiting characteristics of neither a heartless or nobody (It has a heart).
Is this just a coincidence or maybe did they change the Phantom in FM to be more nobody-like?
