Mafty Navue ErinA militant terrorist group (often shortened to "Mafty") opposed to the increasingly corrupt activities of the Earth Federation. By U.C. 0105 Hathaway Noa had became their leader, using their name as a pseudonym for his public broadcasts.
- As Long as It Sounds Foreign: Their name is a mixture of various languages that roughly translates to "Righteous King of Prophets". Gigi lampshades this by pointing out how hamfisted it is.
- True Companions: They have a strong bond as evidenced by Hathaway going the extra mile to rescue Gauman after he had been captured by Lane.
- Well-Intentioned Extremist: They genuinely believe that the Earth Federation has become corrupt and needs to pay for its oppression of Spacenoids, but they use force and assassination to achieve it.

The protagonist of Hathaway's Flash and the leader of Mafty - using the group's name as a pseudonym to hide his identity.
He pilots the Xi Gundam, the final mobile suit created under Project Zeta.
- Adaptation Dye-Job: A weird example but Hathaway is depicted as a brunette (like his mother Mirai) in the original story, as opposed to his raven black hair in Char's Counterattack. It also to carries over into multiple other works that feature Hathaway's Flash despite the discrepancy.
- Anti-Villain: He seems to have good intentions, and he tries to avoid unnecessary death, only targeting important Federation sites.
- Awesome Mc Coolname: Mafty Navue Erin means "Prophet-King of Justice".
- Byronic Hero: Dark, brooding but very passionate about bringing justice and is very charismatic.
- Char Clone: The closest thing this novel has to one, due to his relation to Bright Noa, use of an Ace Custom, and donning a different name - he's the closest to the third type, albeit due to his role as a Villain Protagonist, he's not exactly the Big Bad. And although he doesn't wear a mask, he does obscure his face in public broadcasts.
- Eco-Terrorist: He publicly threatens that he and his organization will continue killing politicians until the Federation ceases all immigration to Earth, for the purpose of halting the planet's pollution.
- Evil Makeover: While the "evil" part is debatable, his darker ambitions are accompanied by swapping out his white spacesuit from Char's Counterattack to an all black one.
- I Let Gwen Stacy Die: Constantly haunted by the memory of accidentally killing Quess.
- Like Father, Unlike Son: He commits violent acts against the government that his father Bright serves. He has also fully adopted the ideology of Char Aznable, one of his father's greatest enemies.
- Living a Double Life: The public knows him as a hero of the Axis Shock event who took down the Alpha Azieru and now works as a botanical researcher. But secretly he's the leader of the terrorist group "Mafty".
- Loves My Alter Ego: Initially has this going on with Gigi.
- Older Than They Look: He should be about 25 years old, but he could still pass for a boy in his teens.
- Psychic Powers: His Newtype abilities have fully awakened, allowing him to effortlessly control the Funnel Missiles.
- Sympathy for the Devil: He studies Char Aznable's life and starts to sympathize with him to such a degree that he begins to carry out his philosophy of preserving the Earth by any means necessary.
- Took a Level in Badass: That little kid from Char's Counterattack has become quite the Mobile Suit pilot.
- Villain Protagonist: A terrorist who serves as the main viewpoint of the story.

The heroine of the story. The young mistress of a millionaire founder of a large insurance company, she boards the fateful shuttle Haunzen whose hijacking leads her to become friends with both Hathaway and Kenneth.
- Betty and Veronica: She's the Archie to Kenneth's Betty and Hathaway's Veronica.
- Love Triangle: She has this dynamic with Hathaway and Kenneth. She herself pursues Hathaway, while being the object of Kenneths affection. Hathaway for his part seemes wary of her, as hes is still dealing with his guilt with Quess.
- Maybe Magic, Maybe Mundane: She has a strange, almost prophetic intuition but whether this is some form of Newtype ability or something else entirely is left ambiguous.
- Red Baron: "Goddess of Victory" by the members of the Circe Unit.
- Ship Tease: With both Hathaway and Kenneth. She seems to fall for Hathaway, within five minutes of meeting him and Perseus him throughout the story. She also is the object of Kenneths affection and occasionaly flirts back with him.
- "Where Are They Now?" Epilogue: After the Hathaway's execution she moves to his birthplace Kyushu alongside Kenneth who plans on setting up another Mafty organisation with Gigi funding them.
An Earth Federation soldier holding the rank of First Lieutenant.
He pilots the Penelope, the result of the Odysseus Gundam equipped with a Minovsky Craft flight unit, which served as the basis for the Xi Gundam's design.
- Ambiguous Situation: It's not made clear whether he is a Newtype or a Cyber-Newtype. In the first novel, Hathaway and Emeralda speculate that he is a Cyber-Newtype, though it is never conclusively determined. For the sake of simplicity, video games often list him as a Newtype, with menu text stating that he can "somehow" utilize the Penelope's funnel missiles.
- Hero Antagonist: He may not be the nicest guy, but he's still trying to take out a terrorist threatening the Federation. Mind you, he's not necessarily a "bad" guy, either.
- Out of Focus: While he and the Penelope are Mafty's biggest obstacle on the battlefield, his commander Kenneth is much more of a personal adversary to Hathaway.
- Rank Up: After the Mafty incident is resolved he is promoted to the rank of Captain.
- The Rival: He serves as this towards Hathaway.
- Shadow Archetype: Serves this to his own commander Kenneth. Both oppose Mafty but Lane is dogmatically loyal to the Federation and is completely blind to the hypocrisy in using immoral tactics to fight terrorists whereas Kenneth slowly questions whether or not they are in the right. This comes to a head by the end where Lane's character is completely static after fighting Hathaway and continues his path in climbing the ranks of the corrupt Federation but Kenneth came around to Hathaway's line of thinking and not only quit the Federation but swore to resurrect Mafty in as its new leader.
- Small Name, Big Ego: While Lane is a very capable pilot, he thinks he's much more skilled then he actually is. Case in point, during his first duel with Hathaway, he has Gawman as a hostage and boasts that he could beat Hathaway without him. Not only does he still lose, Hathaway manages to give him near-fatal injuries while rescuing Gawman, who is completely unharmed.Lane: Impossible!
- Spell My Name with an "S": His name was alternatively romanized as Rein Aim in games for a time.
