Akimi Akatsuki and Akemi Akatsuki
The main protagonist of GC/XO. Originally, they were just one character with two gender choices and some differences depending on the selected gender but, similar to Raul and Fiona, the Original Generation timeline incorparated both of them by spliting them into twins, with Akimi as the "younger" brother, and Akemi as the "older" sister.
16 year old highschool students and the children of Saijou Heavy Industries' president, they get involved in the war when they pilot their newest experimental machine which, depending on player choice, is either the real robot Soul Gunner or the super robot Soul Saber.
They are both pushed by their father into becoming test pilots for his company's machines. Akimi doesn't get along well with his father due to his father's aggressive perfectionism and his own stubborn personality. However, Akemi gets along with him decently enough because of her more cheerful personality.
In Super Robot Wars Original Generation: The Moon Dwellers, Akimi seems to only pilot the Soul Saber FF, while his sister seems to only pilot the Soul Saber GG, with the other sibling working as a sub-pilot depending on the machine out.
- Ascended Fanboy: In OG, Akimi became a BIG fan for the Steel Dragon Group from watching their exploits on the net, and he fanboys over many of their mechas. And then he gets to be the part of the group. He is especially fond of the SRX, as unlike, say, the Compatible Kaiser (which is, as he puts, "just a Super Robot"), it is more a result of the latest advancements in technology.
- Half-Identical Twins: Original Generation only
- Leitmotif: Both Akatsuki siblings have "Charge the Souls of Fighters", "Splendid Star", "Chance of Victory", and "Real Ability".
- Mecha Expansion Pack: Soul Gunner Storm for Soul Gunner, Soul Lancer Burst for Soul Lancer.
- Mid-Season Upgrade: Super Soul Saber for Soul Saber, Soul Lancer for Soul Gunner.
- Talking in Your Sleep: Akemi seems to have a habit of this.
The secretary to Akimi's father, she serve's as the sub-pilot for either of the Akatsuki's.
She was originally a member of Gadisword but escaped to Earth after finding out about Helluga's mad plans to obtain the C.U.B.E./X.E.N.O.N. Engine to rule the universe.
In The Moon Dwellers, she becomes a subpilot upon the Akatsuki's upgrading to the Super Soul Saber.
- Cool Big Sis: 25 years old, intelligent (got a doctorate degree within the short time she arrived on Earth) and has a no-nonsense personality. She is viewed as this by either of the Akatsuki's.
- Meaningful Name: Fairey Firefly was the name of a two-seater airplane during World War II. She's the sub pilot of Akemi Akatsuki's mecha.
- Sole Survivor: She, Sieg, and Sally are the only surviving Gadiswordians at the end of The Moon Dwellers.
President of Saijou Heavy Industries', he has a very strong sense of justice and has yearned to be a hero ever since he was a child. He is the aggressive type that will rush and push those around if he feels there is a need. That aside, he's a successful businessman who has very good management skills, an exceptional network of contacts and has considerable say in political and business circles.
Pretty much pushes his offspring into test piloting for his companies' machines note .
- The Perfectionist: Is willing to push his employees if he thinks it's necessary. It has lead to him and his company being highly successful, however it also cost him his relationship with his son.
GadiswordThe evil faction of GC/XO.
A member of Gadisword, and Akemi's rival. He has a rough personality and is prone to anger, but he's also very intelligent, and is quick to realize that Akemi is pretty clumsy.
In GC/XO, he pilots the Cloud Harken, which requires a pilot with good piloting skills. In The Moon Dwellers, he instead pilots the Leonisis Harga.

- The Smart Guy
- Sole Survivor: Alongside Sally and Fairey, at the end of their plot in The Moon Dwellers.
A member of Gadisword, and Akimi's rival. She has a calm and kind-hearted personality, but she's pretty inexperienced when it comes to love matters so her interactions with Akimi always tend to be comedic.
In GC/XO, she pilots the Kreuz Wahrheit. In The Moon Dwellers, she instead pilots the Leonisis Varga.
- Adaptational Heroism: See Sieg's entry.
- Anti-Villain: She's very polite and friendly, and she has a good (if awkward) relationship with the main protagonist. If you are describing her to someone unfamiliar with her, and then you reveal her affiliation, expect the reaction to be "Wait, whaddya mean she's working for the bad guys?". It doesn't last though. In the OG timeline, she qualifies even less as a villain, as noted above.
