Hunter x Hunter
This 148-episode adventure anime follows 12-year-old Gon as he pursues a dangerous career path to find his absent father, joined by a memorable found-family of friends. The series covers the whole run from 2011 to 2014, and while early episodes feel like classic shounen adventure, the content escalates significantly across later arcs into graphic violence, psychological darkness, and disturbing themes.
Teens 14 and up who enjoy complex, emotionally rich anime; not a comfortable fit for younger children even with supervision.
Episodes to know about
The Hunter Exam arc is the lightest section of the series; people die during the exam but deaths are mostly implied or off-screen, making this the most appropriate stretch for younger or more sensitive viewers.
The Yorknew City arc features organized crime, mass killings by the Phantom Troupe, and notably more on-screen bloodshed than earlier arcs; a pivotal fight involves a character being beaten and killed.
The Phantom Troupe raids the underground auction, with large-scale violence against many characters shown in this episode.
