Well, not neccesairly.
OoT/
TP Ganon transform as a result of the Triforce, while
FSA Ganon transform as a result of the Trident.
TP Ganon form is actually quite different from
FSA ganon who is clear blue like
ALTTP/OoX/
LoZ Ganon.
Either way, there is two ganon. One is born in
OoT and one is born in
FSA, both to the Gerudo. We all know this. However,
OoT Ganon dies in
TP, but
FSA Ganon gets SEALED, just like Vaati did. Who says
FSA ganon can't reappear again after
TP if Vaati can reappear after
TP all the way from
TMC ( Assuming your timeline ).
