Mentors are a key part of many anime series, particularly in shonen. The best mentors guide their apprentices through some of their most pivotal coming-of-age moments. They guide the protagonists through tough times, show them the ropes, and help them become stronger through rigorous training. The best anime teachers improve their student's abilities while fostering their mental fortitude.
Many anime mentors, of course, are among the strongest characters in their respective series. In that case, there's nobody else better for the protagonists to learn from than the best of the best. Some anime mentors, however, are stronger than the rest.

Shonen anime is notorious for its roster of wickedly overpowered characters, but few compare to Assassination Classroom's beloved yellow octopus, Koro-Sensei. Thanks to unethical human experimentation, Koro-sensei became the smiling creature that fans and class 3-E grew to love.
Koro-Sensei is immune to poison, can manipulate his body's fluidity, and compress himself into a sphere called his "absolute defense." It's plain to see why class 3-E struggled to assassinate him before the end of the year. After all, Koro-sensei literally ate half of the moon when he went berserk before coming back to Earth. His body is so powerful that it could destroy the planet if something went wrong.

All Might's absolute strength made society feel safe and protected against the villains for ages. After choosing Izuku to inherit One for All, All Might's strength faded even quicker than before. He showed Izuku how to gradually amp up his OFA usage so he wouldn't hurt himself. When Izuku started developing brand-new quirks, All Might did his best to walk him through everything, even if he didn't have all the answers.

Jiraiya has enough chakra to summon Camabunta, Mount Myoboku's chief toad. Though he's a master of most types of jutsu, Jiraiya's true strength lies in his intellect. Though he acts like a goofy, carefree guy, he's constantly gathering information and observing his surroundings.
1 Satoru Gojo's Birth Altered The Universe's Balance (Jujutsu Kaisen)
Jujutsu Kaisen's Satoru Gojo is a wunderkind in the world of jujutsu sorcery. He was born with both the Six Eyes and Limitless techniques, making him the first in 400 years to possess both. It's said that Gojo's birth altered the universe's balance for the first time in centuries. Cursed spirits and curse users were forced into hiding because someone was out there, ready to defeat them at any moment.
Gojo's cursed techniques are some of the flashiest and most electrifying in Jujutsu Kaisen. Just to name one, his Domain Expansion: Unlimited Void traps his enemies in a metaphysical atmosphere where they're simultaneously inundated with everything and nothing. Most would have expected Gojo to subject Yuji to brutal cursed energy training, but fans loved that he likened honing one's flow to cursed energy to mindfulness while doing other tasks, like watching movies.
