At first, I was highly sceptical of the possiblity.
Now, however, I have come to believe that the director of Gundam SEED/Destiny, may be leading into Newtypes in someway.
For various reasons, I believe that possible Newtypes may include Mu La Flaga/Neo Lorrnoke, Rau Le Creuset, Rey Za Burrel, and maybe Al Da Flaga.
Kira Yamato, also, has been showing the possibility of being/becoming a Newtype.
The greatest eviden of my suspicions are the "Newtype Flashes" that occur between the aforementioned characters. Although, those may also be attributed to cloning, but that does not explain Kira's. Kira's could be attributed to the Ultimate Coordinator Program though.
Anyway, what are your thoughts?
