Mr. Iwamoto (YuYu Hakusho/Ghost Fighter)

Mr. Iwamoto (学上岩本, Iwamoto) is a teacher at Sarayashiki Junior High and is Yusuke Urameshi's enemy.

Why He Sucks

 * 1) He is a hypocrite, as he hates rebels like Yusuke although he steals stuff. More on that later
 * 2) His design, although better than Akashi's, is still unappealing.
 * 3) He doesn't respect the deceased, when he was shown smiling at Yusuke's feuneral.
 * 4) He teamed up with Mr. Akashi to expel Kuwabara and make his friend lose his job.
 * 5) He taught Akashi to erase correct answers and make them wrong, which is very illegal.
 * 6) He attempted to frame Yusuke by stealing another student's pen and making Yusuke the thief when Yusuke didn't even mean no harm and steal the pen.
 * 7) He even tells Keiko to stop hanging out with Yusuke despite Keiko being Yusuke's girlfriend and she doesn't even like Iwamoto.
 * 8) He was later possessed by a demon insect, making him more powerful and terrorizing Keiko and Botan.
 * 9) Despite him doing a lot of horrible things, he hasn't been arrested.
 * 10) His attempt at thievery had led him to his own downfall.
 * 11) He also works for Suzaku.

Redeeming Qualities

 * 1) He did deserve that hit from Yusuke's Spirit Gun
 * 2) At least his design isn't as bad as Akashi's
