Titanus Gigan

Titanus Gigan is a altered titan he has been altered to the point where he no longer needs oxygen making him able to survive space like ghidorah can but he is a naturally accuring titan but is the last of his kind as plasma ghidorah wiped out his species thinking that they are nothing but another thing for him to kill he still thinks gigan should die and is one of the reasons godzilla changed his view on plasma when he realized that he wiped out almost an entire species for no reason the reason the species exists is that when some titans get injured badly they can not heal themselves back to health but it does not die so this species ends their suffering.
