Gundam seed concept using other factors, told form a perspective of a ZAFT soldier as my other cross theme one was told from the perspective of one of Kira's close friends this time it will be one of Athrun's close friends, some references from star wars aside from races and the final fantasy series.
Gundam Seed Retribution has concepts taken from Gundam 00 series and their Gundam meisters been renamed to gundam pilot in this setting the use of GN drives will be seen in the Destiny part of this fanfriction.

Retribution stands for Kira's decisions after he had been captured by ZAFT forces which makes him see the truth behind the Earth Alliance and the people he grew up with. People can change over time a person may one day be your friend and your enemy the next time you meet , this fanfrict explores the meaning of true friends... something that happened to me growing up. Not sure if i should give Kenshin a love interest though.

Delta Saber Gundam

Kenshin is of Japanese descent having brown hair and light blue eyes, he is most often seen in a black leather bomber jacket and a v-neck white shirt, black pants with three interconnecting belts, and black boots and fingerless gloves. He has a silver stud in his left ear, and wears a silver chain necklace with a pendant and a matching ring resembling a winged wolf. Kenshin is a complicated character and a close friend and partner to Athrun to which he sees as a younger brother. His cold, stoic demeanor seems more fitting for a battle hardened veteran than a 17 year old teenager. Athrun comments that he actually a very kind-hearted young man with a strong sense of justice, who keeps his emotions reined in while fighting. Kenshin had lost his family during the tragedy of Junius Seven as the only one who is alive since that day with no one else to turn to Kenshin decided to enlist in the military academy and graduating at the top of their class.
To his friends and other people he is seen as a introverted, cold and taciturn person who pushes away those who would otherwise be considered his friends. Though withdrawn, Kenshin does not shrink from what he considers his duty. On many occasions, Kenshin espouses the philosophy that being emotional on the battlefield will only result in heartbreak, so soldiers need to be able to fight without caring about their opponents. However, he believes that there's nothing wrong with showing emotion in normal situations.
Kenshin is skilled in CQC ( close quarters combat ), small fire arms, but his weapon of choice is is the gunblade known as the blazefire saber

SEED factor -
stands for Superior Evolutionary Element Destined-factor, a controversial and as yet unproven theory about the continuation of human evolution. Both Coordinators and Naturals can possess "the SEED", and those who do are thought by some to be the next stage of human development. This bears some similarity to the Newtype theory of the Universal Century, but the abilities of those with SEED factor appear to be unrelated to Newtype potential. While acceptance of SEED theory is limited, Orb engineer Erica Simmons and prominent religious leader and peace activist Reverend Malchio are known adherents of the theory.

SEED mode - represents the ability for an individual with the SEED factor to enter into a state of enhanced awareness and peak physical ability. While in this state, the person (usually a mobile suit pilot, but not necessarily) demonstrates heightened reflexes and extremely quick information processing. This ability is usually triggered by extreme situations or from recalling significant traumas, often arising out of a need to protect someone else in a critical situation. It is demonstrated visually by cutting to the image of a jewel-like seed, its color matching the color of the experiencer's eyes, dropping from the above and exploding in a shower of light just above the eyes. The physical characteristics are the shrinking of the pupil and growth of the iris. When in SEED mode, a person exceeds his or her normal physical and mental limits.

Force Factor - manifestions of a person's connections to a mystic energy field that binds everything in existance mostly assoated with coordnators and Extendeds, These powers are supernatural abilitys not described by scientists as much of it is still widely not understood.

Beserk mode - often assoated with the Force Factor usually occuring when a person's emotions overtake ther mind, or when the user is sufficiently angered, and its activation is accompanied by an excruciating amount of pain. While they are in Berserk Mode, they are willing to harm or destroy everything in their path to acheive their goals. When they regain their senses, they generally have no knowledge of what happened while they were in Berserk Mode.
A person in berserk mode will have their eyes glow white , or be surrounded in a dark aura in the early stages. He or she is also capeable of unleashing or useing varyious force powers. ( reference star wars ) Once aware of the circumstances, a person can become capable of breaking out of this mode by sheer force of will.
