Coba jelasin Jean Colbert dari Daftar karakter The Familiar of Zero dong

is a professor at the Tristain Academy of Magic who is interested in history; his element specialty is fire magic. He is one of the few people that Saito have in common with. His interest in technology from Saito's world helped him create dragon's blood (actually gasoline) to fuel an airplane. It is revealed that he was the captain of the magic troops sent to burn Agnès' village, D'Angleterre, 20 years ago, but also the person who rescued her, when he found out the village wasn't "plagued", and devoted himself to atone for the sin he committed. He has an anti-war attitude, and is envious when he finds out that modern Japan is not ravaged by war. He reveals himself as the Flame Snake when Albion sends hired mercenaries to attack Tristain Academy, and sacrifices himself to protect Agnès. In the third season, Colbert surprises everyone as he returns with Kirche to Tristain Academy; he had Tabitha cast a spell to fake his death, and was staying with Kirche's family. He constructed a giant airship called the "Ostland", based on Saito's Zero Fighter.

In the novels, Tabitha did not cast a spell on Colbert. Instead, Kirche tricks Agnès into thinking that he is dead. Louise and Saito were also not present during the Academy invasion. He is likely named after Jean-Baptiste Colbert, finance minister to Louis the XIV from 1665 to 1683.
