FIGHT ME

Marinette Dupain-Cheng: The one who rises to make the bread.

Adrien Agreste: The word "agreste" is French for "rustic".

Nino Lahiffe: "Lahiffe" means "the descendant of the hero"

Alya Césaire: Alya means "scarlet" in Slavonic while Césaire is a French variation of Caesarius, derived from Caesar, believed to mean "hair" or "hairy" in Roman, therefore her name means "scarlet hair" which Alya has. Also, Aimé Césaire is a famous poet from Martinique where Alya is from.

Chloé Bourgeois: Chloé means "young green shoot", possibly hinting that Chloé will grow into a better person? Bourgeois relates to the middle-class which discords how Chloé acts as a rich girl who is better than everyone else.

Sabrina Raincomprix: Sabrina means "legendary princess" in English, "from the border" in Italian and "from Cyrpus" or "the river Severn" in Latin. "Rien compris", which sounds similar to "Raincomprix", is French for "understands nothing". The surname could also relate to the comic Asterix where there are many puns and wordplays, like in all these names.

Mylène Haprèle: Mylène is a contraption of the names "Marie" and "Hélène", meaning "bitter" and "moon" respectively. The meaning of Haprèle is unknown, I assume (I may be incorrect) that it has ties to the English surname "Harper".

Alix Kubdel: Alix is a French variation of Alice, meaning "noble" and is also a variation of the name Alex, meaning "defender of man" but I have no idea what Kubdel could mean.

Lê Chiến Kim: Kim is a diminutive of Kimball, a Welsh name meaning "warrior chief" and "le chien" is French for "the dog" while "lé chiến" is Vietnamese for "pear war" according to Google Translate. "Chiến" means war and "Kim" means gold, therefore also referring to the golden war

Ivan Bruel: Ivan is a Russian variation of the name John, Bruel is a variation of "Breuls" meaning "marshy woodland". Patrick Bruel is a singer and Ivan makes music and sings.

Max Kanté: Max means "greatest" and Kanté is possibly related to Kant, meaning "edge" or "corner".

Nathaniel Kurtzberg: Nathaniel means "gift from God", Kurtz is German/Jewish surname meaning "short in height" and the suffix -berg is common in Jewish surnames and means "mountain".

Rose Lavillant: Rose means "rose" or "flower" but I can't find anything for "Lavillant".

Juleka Couffaine: Juleka could be a variation on the name Julia, meaning youth or beauty, "Couffaine" sounds like "coffin", perhaps pointing at Juleka being goth-ish (I don't have a lot of information about Juleka's name).

Lila Rossi: "Lila" is an Arabic name meaning "night", "Rossi" is an Italian surname meaning (the plural) of red, "Lila Rossi" = red night.

Aurore Beauréal: In French, the Aurora Borealis is called is called "aurores boréales", which is a weather phenomenon, hence Aurore being Stormy Weather.

Penny ROLLING & Jagged STONE: (The) Rolling Stone(s). Also Mick Jagger and Jagged.
