Great Philosopher (大哲人, Dai Tetsujin) is an A-Class Rank 13 hero for the Hero Association.


Great Philosopher has a look which is highly reminiscent of the stereotypical look of an ancient Greek scholar. He has black bands covering his hands and a large white beard accompanied by flowing white hair. Typically, he carries around a large book.

Along with that, he has a large vein coming down his bicep and has an athletic build.

Personality Edit

True to his name, he appears to be a very stern and analytical individual. Unlike many other heroes and people in general, Great Philosopher actually tries to understand monsters and asks them about their feelings and intentions. However, they never give him an actual response, and as a result, he always kills them with his book.[1]

Appearances in Other MediaEdit

He and other heroes tried to stop Jumping Spider together, but were easily blown away by the creature because of a misunderstanding of the monster's real capability.[3]
