Great Gozu is known as the Former Super High School Level Wrestler. He graduated as a part of Hopes Peak's 69th class. He appears to be around 32 at the time this takes place. During the actual killing game, Gozu is the 3rd victim, but that could change this time.

Gozu is actually very gentle in nature, despite his intimidating appearance. He has a very quiet and polite way of speaking. He rarely raises his voice, and when he doesn't, it's just to get a point across. He has high morals, and doesn't like persecuting without a fair trial. Gozu also dislikes meaningless violence, and attempts to resolve conflicts quickly. If needed, however, he can easily fight. He states that he will never doubt his allies, and respects them greatly.

Gozu's voice is definitely in the lower register, as he has the deepest voice out of anyone. However, while his voice is deep, it is also soft and gentle, so the actor shouldn't be shouting during the delivery. The actor should also possibly be able to cry while in character, and there will likely be times where he actually does raise his voice.
