(lazily copy and pasting from DA account)

The idea came for this when me and friend were playing Metroid prime 3 for old time sakes, and in that space of free time I thought how the phazon though a "poison" or corruption was still effective and useful when managed appropriately. It's clear from the games there's a theme of an arms race, pirates have phazon, so does the federation in turn. The ones that use it constantly do become quite powerful but at the expense of their own being (ie: the hunters)

What occurred to me that constant use isn't the same as controlled use, using it as and when needed does have some payoffs. 

So I looked at the phazon as a spectrum, a range of different positions within the same group, with blue phazon being the consequence of constant use of phazon to where it becomes misuse and that person is consumed by that very power and become corrupted (aka Dark Samus)

On the other side of the spectrum was the idea that if Dark Samus is the consequence of misuse then maybe if there was an opposite it would be a samus where the phazon has enhanced her as far she will allow it, she is in total control of the phazon because the duration of controlled use has strengthened her natural tolerance and give her body time time to adapt.

In this case the controlled phazon has enhanced her being, as well as manifesting the Chozo DNA within which is depicted as a orange like colour because that is the colour of the chozo eyes.

Hence Chozo Samus. A polar opposite of Dark Samus.

(Think of it as the fierce deity mask version from legend of Zelda.)
