Corbeau has five children. The oldest are two fraternal twins named Lupine and Oleander.
Lupine has Corbeau's eyes and vision (cursed to wear glasses). He focuses on poison types and views himself as the oldest – he was technically born before his brother. He is studious and almost a clone of his father in a lot of ways. Though, he does rely on his twin quite a bit to balance him out.
Oleander has Corbeau's hair colour, but he tends to keep his hair messy. He trains under Philippe and has a talent for using steel types. He and Lupine trust each unfalteringly, so their bond is quite beneficial in what they are set to inherit. He pretty frequently wears a face mask to make himself look more threatening – he looks too soft otherwise.
Third in line is Galan – another boy. He is quite talented with charism, so he is a bit of a playboy and leans towards dark types. He cares a lot about his appearance – he has his other parent's eye shape, but Corbeau's eye colour. (Probably could be besties with Morrigan and is what Grims hoped Nero would be.)
Fourth is Corbeau's only daughter, Wisteria. She is shockingly gentle and kind; almost embodying Corbeau's best side mixed with what he adored about their other parent. She is uninvolved in the Rust Syndicate properly due to that. She is a bug type trainer and loves the Venipede her father gifted her. Corbeau says she looks like her other parent, but most people sat she looks like her father as a girl.
Fifth and final is Lilium – he was an orphan that Corbeau took in. He is a bit more enthused about being in the Rust Syndicate, but he isn't actually yet due to being so young. He is mostly just playing out what he thinks happens and idolises his older siblings. Due to unknown circumstances, he has bad damage in one of his eyes and wears a medical eyepatch to cover it up and keep it safe.
Grisham has two children, a girl and a boy.
Melia is his oldest and the girl. She shares his passion for coffee and helping people. Her smile is just as charming as her father's own, and many around Lumiose seem to love her despite the association her father has with Team Flare. Her customer service is astonishing and attracts many to their café truck. She is a terrifying trainer as her father and specialises in fire types like him. Contrarily, she uses Charizard Y over X.
Cendre is the youngest and a boy. He finds himself enjoying making pastries and has a full intention of becoming a pâtissier. When the siblings work together, they attract a large crowd and also feel capable of helping the most people. While he uses fire types, he seems to lean more towards fairy types. Slurpuff, Dachsbun, and Alcremie are on his team.
Lastly, Ivor has a daughter. One is enough.
Wynne, since he was uncreative and scribbled down the first thing he could think of, is a passionate martial artist who thankfully has the restraint her father lacks. She can get quite a bit annoyed by his antics, like her aunt. Her view of herself is that of a heroine who pursues justice. This means she is constantly harassing Corbeau's children. They do not win against her.
