The faculty of Tohjo Military Academy currently consists of 6 members, all of whom have reached the rank of General in the Counter-Pokémon Division, and are typically referred to by the title of Professor or General.
Surprisingly, most of them are pretty laid back in person, but no one's stupid enough to think that means leniency. When it comes to things involving Pokémon, every single member of the faculty is deadly serious, and can be very strict.
Samuel Oak, Chancellor
A military hero and the foremost authority in all things Pokémon, he rarely gets directly involved with the cadets unless he has to, preferring to focus on his research. He also sometimes has to leave the campus to deal with Pokémon emergencies.
Every time you've met him, you've felt a sense of immense, stifling pressure by just being in the same room with the man, and you admit he intimidates you greatly.
Robert Elm, Vice-Chancellor
The man who's in charge of recruitment, he strikes you as friendly and amiable.
Honestly, if you haven't seen the photos, you wouldn't be able to imagine the man in armour and with a gun in his hand. As far as you know, he's in charge of all administrative issues.
Wilhelm Blaustein, Engineering
A cheerful and casual young man, he's better known as Bill, and is the youngest of the faculty who's still in his 30s.
Actually, he kind of reminds you of Silver in some ways... Except that he doesn't really like to waste his words. He's friendly enough, though. He teaches Marksmanship, Drugs, Traps, and Tools.
Philena Ivy, Ecology
Always seemingly absentminded and a little bit distant, you've never seen her angry, but if the rumour are true... you really don't want to.
She teaches Survival, Navigation, and First-Aid.
Lynnette Joy, Zoology
She's likely the most patient woman that you know. She always speaks in a kind, gentle tone.
She teaches most of the Pokémon-related classes, such as Pokémon Anatomy and Pokémon Behaviour.
Pierre Sigebert, Archeology
A new member of the faculty. You've never met him in person, only from a distance, since he doesn't actually teach any classes yet. The Archaeology department is brand new, after all. Word is he's preparing a new syllabus that will be rolled out next year.
Now that you mention it, he looks like he's around the same age as Bill... But somehow, he's just got this mysterious aura about him.
