Mr. Bolhofner (Modern)

"Mr. Bolhofner" is a minor character (recurring antagonist-turned-supporting character as of season 5) of the 2016 Nickelodeon series, The Loud House. He is a math teacher at Royal Woods Middle School in "Middle Men" and "Hero Today, Gone Tomorrow", and is Lincoln and Chandler's homeroom teacher starting from "Schooled!" due to Mrs. Salter doesn't work out for Lincoln to attend her class with his friends because there's no room in there.

While he was tolerable in the two season 3 episodes, "Middle Men" and "Hero Today, Gone Tomorrow", he underwent flanderization beginning in season 5.

Why He's A Filthy Cruel Teacher Now

 * 1) Originally during the two season 3 episodes he appeared in (“Middle Men” and “Hero Today, Gone Tomorrow”), he was a clean and hygienic teacher who was strict but fair towards his students who taught in a classroom. However, when he became a sixth grade teacher and a true villain in season 5, he was flanderized to become a filthy slob of a teacher who talks down to his students and teaches in a rundown trailer outside the school (in the premiere episode “Schooled!”) for some unexplained reason.
 * 2) He is very sadistic as he punishes his students over something so trivial.
 * 3) He is very mean-spirited towards Lincoln and his friends especially for some unexplained reason.
 * 4) He was at his worst in “Schooled!” (the episode where his flanderization began) where he punishes Lincoln for things that weren't his fault and doesn't even let him explain himself.
 * 5) *He made Lincoln have lunch with him for "disrupting his class" when actually Lincoln was telling Chandler to stop kicking the back of his seat.
 * 6) *He sent Lincoln to the principal's office for being late to class, even though Lynn made him late by shoving him in a locker.
 * 7) He is shown to be very petty for in a couple of episodes:
 * 8) *In “Kernel of Truth” he sued the middle school because Stella guessed his age wrong.
 * 9) *In “No Bus, No Fuss” when Lincoln's mom Rita accidentally cuts him off at the school parking lot, later he takes out his anger at Lincoln by shoving him out of the way and cuts in front of him in line at the cafeteria.

Redeeming Qualities

 * 1) In the episode “Rumor Has It”, it is implied that part of the reason why he's like this now is because of rumors people spread about him at Royal Woods Middle School, showing that he is not completely heartless.
 * 2) *For Sale by Loner also implies another part of the reason why he's like this now is because of the fact that he now lives in the cabin.
 * 3) He is more tolerable in "Flying Solo", "Rumor Has It", "For Sale by Loner" and "Frame on You".
