If I have known that entering Azula is possible as George Collins, I would have done so the instant that I was able to.
This is because of Legion.
Having access to Legion will make everything easier for me. Like super easy. But of course, in order to gain control of Legion, I will have to identify myself as the Supreme Commander. The one and only.
Not me identifying myself, but more like allowing Legion to run a series of tests on my body.
Obviously, I immediately fail the biometric test since this is not my body, but I practically ace the other tests as I do have all of my memories as well as my magical powers.
I just cannot use any magic because I lack any magical energy. I cannot sense any magical energy due to the same reason, but that has more to do with the damn astral dragon snoozing within my spirit.
