Mr. Crabbycat is Jibanyan wearing a gray suit with a brown shirt worn underneath and a dark brown short wig.
In his side series, Mr. Crabbycat is shown to have a short temper and a strict personality.
Despite his short temper, he does honestly care for his students, as shown when they finished a test and he said the scores didn't matter as long as they all tried their best (at least in the Japanese version).
In the anime, he has a crush on "Ms. Blizzaria". He is shown to be in love with her the day she first appears and ends up mocked for this by his students twice. Ms. Blizzaria doesn't seem to reciprocate these feelings, but is a good friend to him.
Then when he goes to Hot Blood Academy, he hears that the teacher is leaving the students Blazion, Swelterrier, Swelton, and Sproink (A.K.A the Anti-Soul Brothers) stone cold, but then to his surprise, he sees Ms. Blizzaria.
The version of Komasan, known as "Mr. Countryfolk" that Mr. Crabbycat works with is his assistant teacher and makes sure that he doesn't actually get physical with the students whenever he gets angry. Mr. Crabbycat deeply appreciates him but is very frustrated when he learns his students prefer Mr. Countryfolk to him.
Mr. Crabbycat spoke with several of them once, as they eat their namesakes (such as watermelons for Watermelnyan), asking for their advice on how to teach.
Mr. Crabbycat cares deeply about his students and will do anything to make sure that they succeed. His known students are Roughraff, Blazion, Fidgephant, Noway, Tattletell, Wazzat, Mad Mountain, and Hidabat.
Roughraff is the one whom he interacts with the most, as he rebels and doesn't want to learn (even going so far as to be the one to prank him about his crush on Ms. Blizzaria the first time (with aid from two other students)). Despite all this, Roughraff does indeed respect his teacher and helps him up after a prank on the graduation ceremony left him slightly injured.
Mr. Crabbycat was frightened by Rubeus J, Hardy Hound, Gargaros, Cap'n Crash, Meganyan, Gutsy Bones and Dromp because when he went to the Disruption Class Academy, they might cause the damage to the entire school.
Abilities and Powers
In the Anime, Mr. Crabbycat makes his appearance. In EP112, Mr. Crabbycat enters Disrupting Class Academy where he teaches Hardy Hound, Gargaros, Rubeus J and Cap'n Crash, but they all they did is to damage the school and Mr. Crabbycat has to fix the mess they make. Mr. Crabbycat can see Meganyan, Gutsy Bones and Dromp as transfer students that can easily dwarf the entire school.
Mr. Crabbycat, known in Japan as Nyanpachi-Sensei, is a homage to the eponymous protagonist of the long-running TV drama Kinpachi-sensei
- His catchphrase is "Nyever hear of spare the paw, spoil the child!?", a reference to the Biblical proverb "spare the rod, spoil the child". He also makes use of "Who's ready to learn!?" as a secondary catchphrase.
- At Anime Japan 2018, Etsuko Kozakura said that she studied the imitation of Kinpachi-sensei from Japanese comedian Matamata Sanmata rather than from Kinpachi for her characterization. The reasoning for this is because that she couldn't be able to imitate Kinpachi.
